Three researchers behind the discovery that our Universe's expansion is accelerating have been awarded this year's Nobel prize for physics. Saul Perlmutter and Adam Riess of the US and Brian Schmidt of Australia will divide the prize. The trio studied what are called Type 1a supernovae, determining that more distant objects seem to move faster. Their observations suggest that not only is the Universe expanding, its expansion is relentlessly speeding up. Prof Perlmutter of the University of California, Berkeley, has been awarded half the 10m Swedish krona (£940,000) prize, with Prof Schmidt of the Australian National University and Prof Riess...

Dartmouth College theoretical physicist Marcelo Gleiser has an interesting essay this week which deals with the possibility of life around the universe and, more to the point, what such life might be like. It was spurred by the recent discovery of one of the most promising possible Earth-like worlds yet, orbiting in the “Goldilocks zone” of its parent star, where water could exist in liquid form. As more and more of these planets are identified, scientists will be focusing their search for possible forms of intelligent life in those regions of the galaxy.But if life exists, Gleiser wonders, would it...

Big as it is, our universe may be just one of many, all floating in a nearly unfathomable "multiverse," scientists say. Problem is, there's been no way to test the idea. Now, though, physicists say they've devised a way to detect "bruises" from our cosmos's purported collisions with other universes. The international team has created a new computer algorithm to hunt for such irregularities in our universe, which they say would be disk-shaped—think of the temporary, circular flattening that happens when one beach ball bumps into another. Because the multiverse would likely have expanded so fast that its universes would...

This is a video of two deep space experiments using the Hubble space telescope. First, Hubble was pointed to a "dark" spot in space and left to collect data for 10 days to see if anything was there. The second is to use this data and the Red Shift to create a 3D image. The result is presented here. To me, pretty amazing stuff. http://www.flixxy.com/hubble-ultra-deep-field-3d.htm

Brilliant, But Distant: Most Far-Flung Known Quasar Offers Glimpse into Early UniverseA gargantuan black hole has been spotted voraciously devouring material just 770 million years after the big bangBy John Matson June 29, 2011 GLOWING GOBBLER: An artist's conception of a quasar ionizing the hydrogen gas surrounding it.Image: Gemini Observatory Peering far across space and time, astronomers have located a luminous beacon aglow when the universe was still in its infancy. That beacon, a bright astrophysical object known as a quasar, shines with the luminosity of 63 trillion suns as gas falling into a supermassive black holes compresses, heats up...

Scientists hoping to puzzle out how the Universe began will find a long-sought theoretical particle — or rule out that it exists — by the end of 2012, the director of the world's largest atom smasher predicted Monday. Rolf Heuer, director of the European particle physics laboratory near Geneva, said his confidence was based on the latest findings from the $10 billion proton collider under the Swiss-French border. "I would say we can settle the question, the Shakespearean question — 'to be or not to be' — end of next year," he told reporters at a major physics conference in...

Astronomers have discovered the largest and oldest mass of water ever detected in the universe — a gigantic, 12-billion-year-old cloud harboring 140 trillion times more water than all of Earth's oceans combined. The cloud of water vapor surrounds a supermassive black hole called a quasar located 12 billion light-years from Earth. The discovery shows that water has been prevalent in the universe for nearly its entire existence, researchers said. "Because the light we are seeing left this quasar more than 12 billion years ago, we are seeing water that was present only some 1.6 billion years after the beginning of...

Victor Stenger, a retired physics prof from the University of Hawaii, has given us two books that explain both atheism and "multiverses", and behold, they are one. Few other proponents of multiverses are quite as forthcoming with their logic, but clearly something besides data must motivate the science of multiverses, because by definition multiverses are not observable. Stenger makes the connection explicit, whereas Hawking or Susskind is a little more coy with their metaphysics. Multiverse-theory is designed for one purpose, and one purpose only, and that is to defend atheism. It makes no predictions, it gives no insight, it provides...

Astronomers have found a nascent star 750 light years from earth that shoots colossal jets of water -- a cosmic fire hose -- out its poles in bullet-like pulses. In a process that almost defies adjectives and analogies, each jet of water is the equivalent of a hundred million times the water flowing through the Amazon River every second and the speed of the jet is the equivalent of 80 times the muzzle velocity of an AK-47 assault rifle. The blast creates huge shockwaves around the star and the process may be responsible for sprinkling the universe with water. And...

Is an Adjacent Universe Causing the Dark Flow of Hundred of Millions of Stars at the Edge of the Observable Universe? Or, Might It Be Something ElseBack in the Middle Ages, maps showed terrifying images of sea dragons at the boundaries of the known world. Today, scientists have observed strange new motion at the very limits of the known universe -- kind of where you'd expect to find new things, but they still didn't expect this. A huge swathe of galactic clusters seem to be heading to a cosmic hotspot and nobody knows why. The unexplained motion has hundreds of...

That's scientists' latest estimate for our galaxy alone, based on Kepler data Roughly one out of every 37 to one out of every 70 sunlike stars in the sky might harbor an alien Earth, a new study reveals. These findings hint that billions of Earthlike planets might exist in our galaxy, researchers added. These new calculations are based on data from the Kepler space telescope, which in February wowed the globe by revealing more than 1,200 possible alien worlds, including 68 potentially Earth-size planets. The spacecraft does so by looking for the dimming that occurs when a world transits or...

Today, looking out across a seemingly boundless cosmos filled with an unimaginable variety of exotic objects, it's easy to forget that the Universe we currently admire is the product of a violent event that occurred 13.75 billion years ago. As we know, the leading theory for universal birth is the Big Bang, where everything came from nothing, in a single energetic burst of inexplicable creation. So, if we turn back the clock back 13.75 billion years, what would we see? My instinct would be to say "energy, the Universe was filled with pure, violent energy," but according to some mind-bending...

Modern cosmology theory holds that our universe may be just one in a vast collection of universes known as the multiverse. MIT physicist Alan Guth has suggested that new universes (known as “pocket universes”) are constantly being created, but they cannot be seen from our universe. In this view, “nature gets a lot of tries — the universe is an experiment that’s repeated over and over again, each time with slightly different physical laws, or even vastly different physical laws,” says Jaffe. Some of these universes would collapse instants after forming; in others, the forces between particles would be so...

Our Universe is an enormous place; that’s no secret. What is up for discussion, however, is just how enormous it is. And new research suggests it’s a whopper – over 250 times the size of our observable universe. Currently, cosmologists believe the Universe takes one of three possible shapes: It is flat, like a Euclidean plane, and spatially infinite.It is open, or curved like a saddle, and spatially infinite.It is closed, or curved like a sphere, and spatially finite. While most current data favors a flat universe, cosmologists have yet to come to a consensus. In a paper recently submitted...

Howard Smith, a senior astrophysicist at Harvard, made the claim that we are alone in the universe after an analysis of the 500 planets discovered so far showed all were hostile to life. Dr Smith said the extreme conditions found so far on planets discovered outside out Solar System are likely to be the norm, and that the hospitable conditions on Earth could be unique. “We have found that most other planets and solar systems are wildly different from our own. They are very hostile to life as we know it,” he said. He pointed to stars such as HD10180,...

Enjoy. I found this by reading down to the bottom of Greg Easterbrook's Tuesday Morning Quarterback column on ESPN.comClick on the source link then click play. Then push the blue square over to the left. Slowly drag to the right and let your mind take it all in. Try not to fall into a thought-induced catatonic state, especially if you are at work.

Best Art in the Universe? Hubble Space Telescope's Amazing Pics From 2010 (Dec. 15) -- You might think that taking highly detailed photographs of the darkest corners of the universe would be a purely scientific job. Turns out, there's an art to it. For the past 20 years, the Hubble Space Telescope has been orbiting the planet and wowing earthlings with breathtaking images of outer space, from jaw-dropping pictures of clusters of newborn stars to fantastic photos of colliding galaxies. But it's not just Hubble's cutting-edge optics that are responsible for these stunning photographs. Behind each image is the hard...

Latest research deflates the idea that the Universe cycles for eternity.Our view of the early Universe may be full of mysterious circles — and even triangles — but that doesn't mean we're seeing evidence of events that took place before the Big Bang. So says a trio of papers taking aim at a recent claim that concentric rings of uniform temperature within the cosmic microwave background — the radiation left over from the Big Bang — might, in fact, be the signatures of black holes colliding in a previous cosmic 'aeon' that existed before our Universe.

The night sky may be a lot starrier than we thought. A study suggests the universe could have triple the number of stars scientists previously calculated. The new estimate is 300,000,000,000,000,000,000,000. That's 300 sextillion. The study questions a key assumption that astronomers often use: that most galaxies have the same properties as our Milky Way. And that's creating a bit of a stink among astronomers who want a more orderly cosmos.

Have we found the universe that existed before the Big Bang? The current cosmological consensus is that the universe began 13.7 billion years ago with the Big Bang. But a legendary physicist says he's found the first evidence of an eternal, cyclic cosmos. The Big Bang model holds that everything that now comprises the universe was once concentrated in a single point of near-infinite density. Before this singularity exploded and the universe began, there was absolutely nothing - indeed, it's not clear whether one can even use the term "before" in reference to a pre-Big-Bang cosmos, as time itself may...
