This is the thread were we post news about and discuss astronomy. We've had some cool threads lately, and I thought it would be good to have future posts appended to one thread.

Planets

Black Holes

Galaxies

Comets

Big Bangs; modest bangs; small, shy bangs

And more!

I'll start, the Washington Post has a cool article today on a probe of the planet Ceres. I think they were being too cute and attempting to generate views by referring to this piddling dwarf-planet as a "planet", without qualification. But no matter, we're there, taking pictures and orbiting.

Whats strange about the Ceres probe is how far away it is from its target. Right now its orbiting at like 22,000 miles. Eventually it will get as close as 250 miles. But Ceres is only 500 miles in diameter. It seems the probe is awfully far away from something so small.

When you learn about all the contingent hoops our planet had to pass through to produce life, and then all the other things that had to happen to produce "intelligent" life, it wouldn't surprise me if we weren't the only intelligent species in our galaxy, or maybe even the entire universe.

But everyone else if they exist is too far away to test that hypothesis.

R20, I also expect many planets with lots of green pond scum. And not much, otherwise. Certainly no mammal-like animals would be nearby. And the most likely nearby planets would be Venus-like (too hot), or Mars-like (too cold) for life.

But in the entire galaxy, I'd bet there is intelligent life of some kind, in many places.

This mirror is used in experiments to measure the distance of the moon from Earth by shooting a lazer at the mirror and timing it's return. The experiment is conducted at facilitates around the world. They found that the moon is adding about an inch a year to its orbit, and will one day escape into space.

Far out, man: 13.1bn-year-old galaxy is most distant yet seen by humans

Galaxy EGS-zs8-1 has moved 30bn light-years away from Earth since it was born: ‘We’re actually looking back through 95% of all time to see this galaxy’

Alan Yuhas in the Milky Way, Thursday 7 May 2015 15.22 EDT

A team of astronomers has measured a galaxy farther than any other ever seen by human beings, reporting this week that the ancient star system offers a glimpse of what the universe was like not all that long after the beginning of time.

Astronomers from Yale University and the University of California Santa Cruz announced in the Astrophysical Journal that they had identified a galaxy that formed about 13.1bn years ago, making it the earliest measured galaxy known in the 13.8bn-year history of the universe since the big bang.

The newly measured galaxy, given the unromantic moniker EGS-zs8-1, now holds the record for distance: because the universe has continued to expand since its original existential spasm, early galaxies moved farther and farther outward over the millennia, eventually putting EGS-zs8-1 an estimated 30bn light-years away from Earth.

But because light can only travel so fast through the vast distances of space, what reaches Earth is actually old light – the sight of what the sun looked like a few minutes ago rather than what it looks like at that moment.

Light reflected off the moon takes 1.3 seconds to reach Earth, sunlight takes eight minutes and light from a distant galaxy takes billions of years. The effect, through powerful telescopes like the Hubble, is of looking into eons past.

So what we see in EGS-zs8-1 is happening a long time ago, in a galaxy far, far away.

“We’re actually looking back through 95% of all time to see this galaxy,” Garth Illingworth, an astronomer at the University of California Santa Cruz and co-author of the paper, told the Los Angeles Times. “It’s really a galaxy in its infancy,” he added, “when the universe was in its infancy.”

Astronomers can therefore see these ancient, distant galaxies as when they were “young” and in an early form. EGS-zs8-1 is unusually large and bright among the known early, distant galaxies, already about one-sixth the mass of the Milky Way – about 8bn suns – and creating stars 80 times faster than our galaxy, the researchers found.

“While we saw the galaxy as it was 13bn years ago, it had already built more than 15% of the mass of our own Milky Way today,” Yale researcher Pascal Oesch, the lead author of the paper, said in a statement. Oesch suggested that the research would help illustrate some of the earliest epochs of the cosmos: “The universe was still very young then.”

“By looking at different galaxies as a function of time, we can reconstruct the buildup of the heavy elements that we see around us today and that we’re all made of,” Oesch said. He added that the data gave clues as to “how the stars were forming at these extreme distances, and they seem to be forming differently than the local universe. Every discovery opens up a whole new set of questions.”

Both Oesch and Illingworth said that the Hubble appears to show many more light sources and likely galaxies even farther away, but that they cannot yet measure their distance. With more data about more distant galaxies, researchers hope to gain insight into how galaxies formed, and so quickly, after the big bang.

Scientists have raced in recent years to discover ever more distant and older galaxies, in paradoxical pursuit of clues to the early universe. Astronomers try to measure distance by seeing how starlight stretches, or “redshifts”, from the ultraviolet levels of high-energy light down to what’s visible to the eye, and then farther down to infrared levels. As the universe expands at an accelerating clip, the light stretches along longer wavelengths and becomes “redder”.

To measure the distance of this galaxy, the Yale and UC Santa Cruz team used a spectrograph called Mosfire mounted on a specialized telescope – itself mounted on the dormant volcano of Mauna Kea on Hawaii. Nasa plans to launch a new super telescope, the James Webb Space Telescope, to join the ageing Hubble in orbit, and also to add a gigantic Thirty Meter Telescope to the observatory complex in Hawaii.

I dragged my telescope out last night. I saw Venus before it set. Venus goes through phases like the Moon, but was full last night. Then I found Jupiter. I saw four sparkly moons in space around the big guy.

Saturn was rising too late and it was too cold to dilly-dally, so I missed that planet. Trees blocked my view of Mercury as it was setting, and the moon had set early, too.

I'm looking forward to using the telescope in Summer.

Yes, you are looking into the past. When you look at the moon, you see with light that takes about 2.5 seconds to reach you from the moon. You therefore see the moon as it looked about 2.5 seconds earlier. When you go further out in space, which is very big, you get longer delays. I think we can only see things that are up to about 13.5 billion light years ago. We can't see further because time only began with the Big Bang, which was about 13.8 billion years ago.

How's that for freaky!

We recently got a close encounters with an ELE asteroid, and didn't know it until it was past us. It passed INSIDE the moon's orbit. There is some other ELE sized object that they do know of, which is making a flyby some year soon. They aren't worried about that event; however, we won't know until it passes if the flyby will perturb its orbit, so that when it returns 20 years later for another flyby, it might run smack into us. At least they know about this one. If it's trouble, they have a couple decades to figure out how to prevent it. Maybe they will just send us all into the past via time travel?

by Anonymousreply 11407/01/2015

R110, the one I find freaky is that a star could go supernova nearby, and under certain conditions, we won't know about it until it obliterates the entire planet in a millisecond. We'll have no advanced notice, since the x-rays and other energetic rays that will fry us travel at the speed of light, and nothing travels faster, so there is no way to know in advance. The star Beetlejuice is a candidate for just such an event. Astronomy writer Phil Plait says we are in no danger, but I have reservations, based on nothing.

Black Holes Aren't As Black As Thought, Says Stephen Hawking In New Theory

August 25, 2015 | by Jonathan O'Callaghan

Stephen Hawking says he may have solved a problem that has plagued astrophysics for 40 years: the information loss paradox.

For decades, scientists have argued about what happens to the information relating to the death of a star that forms a black hole. It’s known that nothing, not even light, can escape from a black hole owing to its intense gravitational pull. Quantum mechanics, though, says that information cannot be destroyed; general relativity says it must be. Hence, the information loss paradox.

In the 1970s, Hawking said black holes could emit “information-less photons” via quantum fluctuations – tiny perturbations in space-time – called Hawking radiation, but in 2004 he produced a new theory that claimed information could actually escape from a black hole. How that would occur wasn’t clear, but now he says he has an answer.

[quote] Jupiter and Saturn, the gas giants, are something like our solar systems’ favored children. Their ice giant siblings, Uranus and Neptune, have received much less attention over the course of our explorations of the planets. A significant group of readers wanted to rectify that. Of the two planets, interest in Uranus was greater. Marjorie Parent-Greenman of Ann Arbor, Mich., explained what fired her imagination with a number of questions: “It’s the only planet, in our solar system, with a tilted axis. How, or why, did that happen? Has it always been tilted? If not, what caused it?” Lucas, a 7-year-old also in Ann Arbor, wrote, “It’s so colorful and beautiful, and it’s interesting to learn about a colorful and beautiful planet.”

[quote] Another reader, Dan Moss in Dallas, offered a more novel justification for studying the seventh planet from the sun: That unfortunate name — Uranus — has made a perfectly fine planet the butt of every schoolyard joke and late-nite wisecrack in English. Nothing would rehabilitate poor Uranus like a proper, awesome visit.

I've always had a soft spot for Uranus. It's such an underrated planet that's often labeled "the most boring planet" because of its uniform atmosphere. Plus it's constantly the butt of lame jokes.

I just learned that Saturn's moon, Titan, orbits in reverse direction. It goes around reverse to the direction of the planet's rotation. This would not be natural forming. It was probably cruising by and was captured by the planet. The show I'm watching said it was captured in a crash with another object; but if things were right, it might have been captured simply by gravity, perhaps by more than one object. But reverse is weird! .

R212, they strangely use the seemingly unique term for a few different things. I've heard it used for the point from which the big-bang banged. I've also heard it used for a black hole, especially any black hole at the center of a galaxy. I've lastly heard it used for any oddity that seems to originate from a small point.

One thing they all have in common is that there is a lot unknown and unknowable about their origination, and the physics within them. So in part, the word is a smart sounding way to stand-in for the expression that a lot is unknown.

So, it might be less confusing to know that the definition seems to depend and vary based on context.

Edinburgh University astronomers find sunless world

3 November 2015

Clouds made of droplets of molten iron have been detected on a sunless world 75 light years from Earth.

The planet-like object, PSO J318.5-22, was already considered one of the strangest ever discovered.

About the same size as Jupiter, it floats freely out on its own in space.

Scientists estimate it is only about 20 million years old. Edinburgh University astronomers used a telescope in Chile to show it is covered in multiple layers of thick and thin cloud.

It has no parent star. Hot dust

Without the dazzling light of a parent star, the team was able to carry out accurate measurements of the object's varying brightness.

They estimated temperatures inside its clouds to exceed 800C. The clouds were made up of hot dust and molten iron.

Dr Beth Biller, of the University of Edinburgh's School of Physics and Astronomy, said: "This discovery shows just how ubiquitous clouds are in planets and planet-like objects.

"We're working on extending this technique to giant planets around young stars, and eventually we hope to detect weather in Earth-like exoplanets that may harbour life."

The findings are published in The Astrophysical Journal.

Every time half of the Earth faces the Sun, we experience the brightness of daytime, the Sun’s energy and light driving weather, biology and more. But in space, NASA’s Solar Dynamics Observatory (SDO) keeps an eye on our nearest star 24/7. SDO captures images of the Sun in 10 different wavelengths, each of which helps highlight a different temperature of solar material. In this video we experience images of the Sun in unprecedented detail captured by SDO. Presented in ultra-high definition video (4K) the video presents the nuclear fire of our life-giving star in intimate detail, offering new perspective into our own relationships with grand forces of the solar system.

R241, if Mars were Earth size, it would still have a liquid metal center, and a magnetic field. The field would have protected it's atmosphere from the Solar winds, and it would therefore still have liquid water on its surface.

Due to the occasional exchange of rocks between Earth and it, this means it could have had life swimming around in these bodies of water.

R294 Earth has been emitting signals for decades. If any other intelligent life form has techonology capable of deciphering our signals then they certainly know of our existence. As far as I know, we haven't been able to find signals coming from other worlds that suggest they are the product of intelligent beings...

On the other hand, I think that scientists would use other methods to find life on other planets such as light. Aparently, light can give a some data on the composition of a planet, perhaps the gases of its atmosphere and all that stuff.

The idea of our radio and television audio signals being transmitted through space and being discovered by an alien race is actually a fallacy. It only takes a short distance - I think it's about a light-year more or less - before the signal starts to degrade and becomes nothing by noise. If it were to reach the neared possibly inhabitable regions of space, the audio signal would be unintelligible.

by Anonymousreply 29612/21/2015

Also, as I understand "broadband" transmissions, signals are sent in packets on multiple channels at the same time. A single message is all sliced and diced. I would imagine that this makes the detection of a signal very complicated, because you have to reassemble the message from multiple channels to make any sense of it. It adds a layer of complexity that another party might not be expecting; and not know how to, or care to, reassemble. .

They say on TeeVee that a nuclear bomb wouldn't be helpful because it just makes many smaller radioactive missiles headed for Kansas or wherever, instead of one big one. I'm not convinced. These smaller missiles will have greater surface area, and therefore burn up in the atmosphere more effectively. I think it depends on the original size of the asteroid. They never discuss that. (I know the Russian idea is to completely move the asteroid away from a collision, but I'm thinking "big picture" here).

[bold]New evidence suggests a ninth planet lurking at the edge of the solar system[/bold]

Astronomers at the California Institute of Technology announced Wednesday that they have found new evidence of a giant icy planet lurking in the darkness of our solar system far beyond the orbit of Pluto. They are calling it "Planet Nine."

Their paper, published in the Astronomical Journal, describes the planet as about five to 10 times as massive as the Earth. But the authors, astronomers Michael Brown and Konstantin Batygin, have not observed the planet directly.

Instead, they have inferred its existence from the motion of recently discovered dwarf planets and other small objects in the outer solar system. Those smaller bodies have orbits that appear to be influenced by the gravity of a hidden planet – a "massive perturber." The astronomers suggest it might have been flung into deep space long ago by the gravitational force of Jupiter or Saturn.

Telescopes on at least two continents are searching for the object, which on average is 20 times farther away than the eighth planet, Neptune. If "Planet Nine" exists, it's big. Its estimated mass would make it about two to four times the diameter of the Earth, distinguishing it as the fifth-largest planet after Jupiter, Saturn, Uranus and Neptune. But at such extreme distances, it would reflect so little sunlight that it could evade even the most powerful telescopes.

Confirmation of its existence would reconfigure the models of the solar system. Pluto, discovered in 1930, spent three-quarters of a century as the iconic ninth planet. Then, a decade ago, Pluto received a controversial demotion, in large part because of Brown.

His observations of the outer solar system identified many small worlds there – some close to the size of Pluto –and prompted the International Astronomical Union to reconsider the definition of a planet. The IAU voted to change Pluto's classification to "dwarf planet," a decision mocked repeatedly last summer when NASA's New Horizons probe flew past Pluto and revealed a world with an atmosphere, weather and a volatile and dynamically reworked surface.

Brown, who tweets under the handle @plutokiller and who wrote the book "How I Killed Pluto and Why It Had It Coming," said now may be the time to rewrite the textbooks yet again.

"My daughter, she's still kind of mad about Pluto being demoted, even though she was barely born at that time," Brown said. "She suggested a few years ago that she'd forgive me if I found a new planet. So I guess I've been working on this for her."

rown and Batygin initially set out to prove that Planet Nine didn't exist. Their paper builds on earlier research by two other astronomers that revealed a peculiar clustering of the small, icy objects discovered in the past decade or so in the remote regions of the solar system.

In 2014, Scott Sheppard of the Washington-based Carnegie Institution of Science and Chad Trujillo of the Gemini Observatory in Hawaii published a paper in the journal Nature that discussed the potential existence of a giant planet affecting the orbits of those dwarf worlds. Sheppard and Trujillo noted a similarity in the motion of those bodies when they are closest to the sun.

Do I understand correctly that gravity isn't a force at all? It's the curvature of space, in 3-d (at least 3-d, but that's another matter). That is why it can "act" over long distances between objects that have no other interaction. I gather that this is the case.

If this is true, does that mean there are really no such things as "gravity waves" or particles? I think I occassionally see eggheads setting up experiments that are designed to look for gravity particles, but I don't think they exist, because gravity is just the warping of space-time, and not a force.

I'm confused about this. Can anyone explain simply and concisely? Thanks!

by Anonymousreply 35701/25/2016

But how precisely does a ED object curve space-time?

You usually see the model in which a ball in put on a stretched piece of cloth held from its edges causing the curvature of the piece of cloth. That works perfectly if you think that the piece of cloth is put horizontally and gravity does the rest, however, how do you apply this to space-time? Space-time is not a horizontal piece of fabric and there isn't gravity from any side to cause the curvature when putting a planet in the middle.

by Anonymousreply 39802/05/2016

R397, this crash was responsible for knocking the Earth off its axis. (Normally, a planet would spin with its equator parallel with its orbital plain, and spin in the direction that it circled the Sun.) The axial tilt causes the seasons. Venus and Uranus must have experienced something similar. Venus rotates backwards, very slowly. Uranus actually rotates on its side (off by 90°).

The Earth-Moon relationship stabilizes each other's orbits. Without the Moon, the North Pole would occasionally exchange places with the equator. This would be hostile to life formation. (Mars has only two tiny Moons, not big enough to stabilize its orbit. As a result, Mars experiences this kind of wobble.). Even so, the Earth wobbles very slightly, but not enough, apparently, to over-stress living things.

The heavy metals in both the original Earth and Theia joined and mostly settled into the center of the Earth. These molten metals cause our magnetic field. This resulted in the Earth having a much larger magnetic field that one would expect for a planet its size, since it had the metal from two planets, essentially. This magnetic field deflects dangerous solar radiation. Life might never have left the water without this oversized magnetic field. Meanwhile, the Moon mostly consists of rock which is lighter than metal. My understanding is that Moon rock matches Earth rock in composition, though I thing this article disputes that.

Mercury had a mysterious event as well that ripped-off its outer shell. They don't know how this happened, but another collision seems reasonable.

Without this collision, we'd have no regular seasons; our climate would change unpredictably, severely, and frequently (like on Game of Thrones and their lament that "Winter is Coming", and their seasons lasting an unpredictable length of time.); and there would be little life on land because of the solar radiation.

If all goes as the scientists hope, this will be the kick-off for an era of gravitational wave astronomy: for learning about some of the most extreme and violent events in the cosmos by measuring the tiny ripples of space distortions that emanate from them.

Time to brush up on your gravitational wave knowledge, if you haven’t already done so! Here’s a visualization to help you – and we’ll go step by step to see what it means:

If you have a big piece of sponge in the shape of a square and you put a relatively big ball inside it will cause a ripple pushing outwards in all directions.

by Anonymousreply 40702/10/2016

Well, the ball will push the sponge arounf it outwards to make room for itself whereas the sponge will fight back trying to regain the space that the ball occupies inside the sponge. The characteristics of the ripple caused by the ball are define by the two fighting forces when finding the balance betwen the two of them.

[bold]Breakthrough: Scientists detect gravitational waves, just as Einstein predicted 100 years ago[/bold]

In a groundbreaking discovery, scientists say they have finally detected gravitational waves — ripples in space-time from a violent collision 1.3 billion light-years away — that serve as a resounding confirmation of a prediction made by Albert Einstein a century ago.

The detection, made with the Laser Interferometer Gravitational-Wave Observatory, known as LIGO, is the culmination of a decades-long search for signs of this elusive phenomenon.

The discovery, described in a paper in Physical Review Letters, will open a new window onto the universe, said LIGO executive director David Reitze.

“Until now we have been deaf to gravitational waves – but today we are able to hear them,” Reitze told a packed room at a press briefing in Washington D.C.

Astronomers rely on light of all wavelengths to detect the universe. Visible light reveals the starry heavens; infrared allows us to penetrate further back in time to see older, more distant stars; radio waves reveal the afterglow of the universe’s violent birth; and X-rays showcase violent encounters in the cosmos, including the supernova deaths of massive stars.

With the exception of the nascent field of neutrino astronomy, scientists have nearly always relied on their (or their telescope’s) ‘eyes’ to view the distant heavens. But now, researchers will be able to sense the universe in a whole new way: with their ‘ears.’

The telltale ripples were picked up just before 2:51 Pacific Daylight Time on Sept. 14 by the twin LIGO detectors – one in Hanford, Oregon and the other in Livingston, Louisiana – a mere three days after the detectors had gone live following a five-year upgrade. The L-shaped detectors send laser beams down each leg of the L, which have the exact same length. If a gravitational wave passes through the detector, it will squeeze one leg and stretch the other, causing the distance to change and thus creating slight differences in timing.

Gravitational waves occur as objects move through space, almost like a boat moving on lake sends ripples through the water’s surface. But they’re so tiny that until now it’s been nearly impossible to detect them, even those caused by something as large as a planet moving around the sun. (The fact that they’re imperceptible on these scales is probably a good thing – objects lose energy as they emit gravitational waves, and if a body like the Earth lost too much, it would eventually fall into the Sun.)

So to pick up this signal, scientists have to look for massive, violent events in the universe. This particular signal appears to have been caused by a collision between two black holes (20 and 36 solar masses) that occurred some 1.3 billion years ago.

During the smashup, the two black holes combined into one, and turned about three suns’ worth of mass into gravitational waves in just a fraction of a second. At its peak, the power output was about 50 times the output of all the stars in the visible universe, the researchers said.

“It has been a long journey … we are very proud of this work taking a village – a worldwide village,” Gabriela Gonzalez, LIGO’s spokesperson at Louisiana State University, said at the press briefing.

Reitze, who compared the achievement to the moment when astronomer Galileo first turned his telescope to the heavens, said this would allow scientists to begin studying the cosmos in a whole new way.

“This was truly, I think, a scientific moonshot,” he said. “I really believe that. And we did it. We landed on the moon.”

If the universe is expanding which is observable by seeing galaxies getting away from each other how then could such small objects like planets and stars cause ripples in space-time if the force that causes the expansion of the universe is much stronger when streching out space-time?

First, there was the idea that Martians built canals. Then that was dismissed, as was the idea that water existed there. I think that was the 1970s. Them more recently, they started to think there might be water there. I think it was only confirmed for fact in the last couple years or less.

Alien ‘Wow!’ signal could be explained after almost 40 years

A former analyst with the US Department of Defence is on the trail of an astronomical ‘cold case’ – an unexplained signal that some believe could have come from extraterrestrials

Stuart Clark, Author of The Unknown Universe, and co-host of The Stuniverse podcast. Thursday 14 April 2016 12.59 EDT

Way back in 1977 something amazing happened (apart from the release of Star Wars obviously). Astronomer Jerry Ehman was using the Ohio State University’s Big Ear radio telescope to sweep the sky for possible signals from extraterrestrial civilisations. He found something.

While pointing towards a grouping of stars called Chi Sagittarii on 15 August, he received a powerful blast of radio waves that lasted for 72 seconds. He circled it on the readout and wrote: “Wow!”

Analysis of the signal showed that it displayed all the hallmarks of coming from interstellar space, and it became something of a cause célèbre for those involved in SETI, the search for extraterrestrial intelligence.

The trouble is that despite numerous attempts, the signal has never been observed again and so remains unexplained. Until now perhaps, thanks to the work of Professor Antonio Paris of St Petersburg College, Florida.

Before he was an astrophysicist at the St Petersburg College, Paris was an analyst for the US Department of Defence. “I have this investigative background, so I approached the ‘Wow!’ signal as I’m going back to the crime scene,” he told me over Skype. “It’s a cold case, so I went to various [astronomical] databases to find culprits or suspects that were at this crime scene at the time.”

He didn’t find aliens but he did find two suspicious looking comets.

Known as 266P/Christensen and 335P/Gibbs, they have never been investigated before because they were only discovered in 2006 and 2008 respectively. Paris found that they were both in the vicinity of Chi Sagittarii on the day that the ‘Wow!’ signal was detected.

This could be significant because comets are surrounded by clouds of hydrogen gas that are millions of kilometres in diameter. The ‘Wow!’ signal itself was detected by Ehman at 1420MHz, which is a radio frequency that hydrogen naturally emits. He published his idea at the beginning of this year.

But before the case can be closed, Paris must test his hypothesis and for this he needs public support.

Comet 266P/Christensen will pass the Chi Sagittarii star group again on 25 January 2017, while 335P/Gibbs will make its passage on 7 January 2018. Paris plans to observe these events to look for a recurrence of the mystery signal. But time is not on his side for using an existing radio telescope – they are all booked out.

So, he has launched a crowdfunding campaign on gofundme to raise the $13,000 he needs to buy a radio telescope to make the observation. Donations are rolling in and he is already most of the way to his target.

“I would like to [be fully funded] in May, order the stuff so that I can have it by October,” he says. This would give him time to construct the dish, test it and prepare for the January encounter.

Although some other astronomers have voiced scepticism at his hypothesis, Paris points out that even if he turns out to be wrong, it’s still good science because we are learning something about comets, and he and his colleagues have a new radio telescope that they can use for further research.

Also on the plus side; if it isn’t comets, SETI scientists still have their best candidate for an extraterrestrial signal.

Discovery could help explain how 'cosmic dark ages' ended.

Scientists have detected and confirmed the faintest early-universe galaxy ever, using the W. M. Keck Observatory on the summit on Mauna Kea in Hawaii. The team detected the galaxy as it was 13 billion years ago.

Hubble finds universe is expanding faster than expected.

Astronomers have obtained the most precise measurement yet of how fast the universe is expanding at the present time, and it doesn’t agree with predictions based on other data and our current understanding of the physics of the cosmos.

by Anonymousreply 55206/16/2016

I though that gravity was simply the observation of objects moving through warped spacetime caused by objects with mass. In other words, it doesn't actually exist as a force at all, it just appears to be a force. In which case, there shouldn't be any thing like a gravatational wave or particle. Am I wrong about this?

Scientists begin modelling universe with Einstein’s full theory of general relativity.

In a simulation of the universe without commonly made simplifications, galaxy profiles float atop a grid representing the spacetime background shaped by the distribution of matter. Regions of blue colour contain more matter, which generates a deeper gravitational potential. Regions devoid of matter, darker in colour, have a shallower potential.

Why ultra-powerful radio bursts are the most perplexing mystery in astronomy.

Strange signals are bombarding Earth. But where are they coming from?

by Anonymousreply 56406/29/2016

I'm sorry, R564, I left my short wave radio on by mistake!

When I was a kid, I had this suped-up radio that allowed me in New England to get radio signals from as far as Key West, Florida. It wasn't a short wave radio, but something else. It was as big as a breadbox, and used vacuum tubes that had to warm up before it worked. I seem to recall getting signals from Australia, too, but maybe that's a fantasy. That was in the 70s, before air travel was deregulated and affordable for the average Joe. If you were going to Florida, you'd drive, usually. So, these long distant signals were like they were coming from another world. Maybe they were!

Hubble views a stubborn dwarf galaxy.

Dwarf galaxies are small, faint collections of stars and gas. Their diverse properties make them intriguing objects to astronomers, but their small size means that we can only explore those that lie closest to us, within the Local Group, such as LEDA 677373 shown above.

Last night, I was watching a documentary about Asteroids on DCh and, while it is true that there is the risk of being hit by an asteroid in the future I then thought, right now the most dangerous threat we are facing is religion, islam in first place and the the rest of Abrahamic religions. These are more lethal than asteroids today and more capable of wiping life off the face of the Earth.
