Astronomers Detect Signal From 13.4B Years Ago

Signal shows dawn of the universe, possible evidence of dark matter

(Newser) - After the Big Bang, it was cold and black. And then there was light. Now, for the first time, astronomers have glimpsed that dawn of the universe 13.6 billion years ago when the earliest stars were turning on the light in the cosmic darkness, the AP reports. And if... More »

Largest Structure Ever Found Is a Really Cold Hole

Some call the discovery independent evidence of dark energy

(Newser) - Researchers using NASA's Wide-Field Infrared Survey Explorer and a telescope in Maui have discovered what they are calling the "largest individual structure ever identified by humanity," reports the Royal Astronomical Society . So large, in fact, that the only way to measure its size is in light-years—1.... More »

Darkness Reigned for 550M Years

Stars didn't appear until 100M years later than we thought

(Newser) - After the Big Bang, it was dark for a very, very long time—even longer than experts had previously believed, the Smithsonian reports. Scientists had thought that the dark period between the Big Bang and the emergence of the first stars lasted about 440 million years, the Press Association reports... More »

Amazing Simulation Shows How Universe Formed

'Dark matter' helps create accurate model, researchers say

(Newser) - It's like "flying through the universe way faster than the speed of light and watching galaxies as they are assembling," says one of the researchers who has created a stunning visual simulation of how the universe formed. The "Illlustris" model created by an international team of... More »

Majority of Americans Doubt the Big Bang

Poll shows 51% Americans unsure

(Newser) - Americans aren't really sold on scientific consensus. A new AP-Gfk poll finds that while the public generally believes scientists on issues of personal health—just 4%, for example, doubt that smoking causes cancer—there's widespread doubt on bigger picture subjects. A slim majority (51%) said they doubted the... More »

Universe 80M Years Older Than We Thought

Scientists get most accurate look yet at Big Bang-era radiation

(Newser) - The universe has been around just a bit longer than we've given it credit for. Scientists today unveiled the most accurate data ever recorded from the radiation left over from the milliseconds after the Big Bang, revealing that the universe is roughly 80 million years older than advertised, Science...

Scientists Glimpse Universe's First Stars

The glow is almost as old as time itself

(Newser) - Star light, star bright, the first stars have actually been glimpsed—or at least their light has, reports . Astronomers in California studied massive black holes, called blazars, that give off huge amounts of light while swallowing up matter—and were able to separate out a glow from what... More »

GOP Rep Blasts Evolution as Lie ‘Straight From Pit of Hell’

Paul Broun tells church group science meant to keep people from their savior

(Newser) - Rep. Paul Broun, a Georgia Republican and medical doctor whose musings on the president have landed him on the House Wingnut Index , is mincing no words on his views on evolution, reports Talking Points Memo . “God's word is true. All that stuff I was taught about evolution and... More »

Hubble 'Travels' Back 13.2B Years

'Time-tunnel' composite bares space 'just' after Big Bang

(Newser) - An out-of-this-world composite photo of Hubble Space Telescope shots peers back to a time a "mere" 450 million years after the Big Bang. Dubbed the eXtreme Deep Field, or XDF, the photograph—made up of 2,000 snaps taken by the Hubble over 10 years—reveals nearly 5,500... More »

Oldest Spiral Galaxy Shocks Astronomers

'Grand-design' spiral formed only 3B years after Big Bang

(Newser) - An ancient galaxy has flabbergasted astronomers. The perfectly formed spiral galaxy was born eons ago, a mere 3 billion years after the Big Bang. But this galaxy type was considered impossible so early on, when the cosmos was too chaotic to mold a "grand-design" spiral. How did it appear?... More »

Hottest Temp Ever Created by Man: 7 Trillion Degrees

Physicists produced it during quest to learn more about Big Bang

(Newser) - A team of New York physicists has managed to smash gold ions into a quark-gluon plasma much like the one believed to have existed in the milliseconds after the Big Bang—and in the process broken the Guinness World Record for the hottest man-made temperature ever recorded. The plasma hit... More »

God Not Necessary for Big Bang: Scientists

But that doesn't mean there is no God

(Newser) - The Big Bang could have brought the universe into existence whether or not God exists, researchers said at the recent SETICon 2 conference. "The Big Bang could've occurred as a result of just the laws of physics being there," said one astrophysicist. "With the laws of... More »

Japanese Team Spots 'Oldest Galaxy'

Astronomers believe galaxy is nearly 13 billion years old

(Newser) - A long time ago, in a galaxy far, far away, light was apparently emitted that has now been detected by Japanese astronomers using telescopes at the summit of Hawaii's Mauna Kea volcano. The team says the galaxy is 12.91 billion light years away and is the oldest one... More »

Scientists Spot Gas Clouds That Seeded All Life

Early formation created stars that led to our own

(Newser) - Astronomers have caught a first-ever glimpse of gas clouds as they existed just a few minutes after the big bang, the Los Angeles Time s reports. These clouds—long gone by now, but still visible to us—contain lighter elements like hydrogen and helium, which condensed into stars during the... More »

Scientists Spot Signs of 'Shadow' Universes

Space telescope testing 'multiverse' theory

(Newser) - Scientists who believe our universe is just one of many have found a way to put their theory to the test. The "multiverse" theory holds that our universe is in a bubble of space and time drifting in a sea of other "bubble universes." Cosmologists say that... More »

Bits of One Universe's First Stars Spotted

Remains of early star a 'Holy Grail' of astronomy

(Newser) - Astronomers believe they have spotted the remains of one of the universe's very first stars—a "missing link" between the Big Bang and today's universe. The gas cloud left behind when the star exploded more than 13 billion years ago was illuminated by light emitted from a quasar, the... More »

Collider Scientists Launch 'Mini Big Bang'

Experiment generates highest temperatures ever achieved

(Newser) - Scientists have used the Large Hadron Collider to smash together lead ions and create a "mini Big Bang" for the first time. The ions collided at close to the speed of light, creating temperatures a million times hotter than the heart of the sun. The "soup" of subatomic... More »

Hawking: Universe Didn't Need God to Begin

'Laws of physics are all that's necessary for creation'

(Newser) - The universe didn't need God to begin; it was quite capable of launching its existence on its own, thank you very much, says reknowned physicist Stephen Hawking. The universe began with the Big Bang, which simply followed the inevitable law of physics, the scientist writes. “Because there is a... More »

Space Telescope Captures Big Bang Radiation

Planck beams back microwave map of entire sky

(Newser) - The European Space Agency’s Planck space telescope has beamed back its first, much-anticipated image: a map of the entire sky, composed of microwave light. That bright line in the center of the image is our own Milky Way galaxy, and the lights surrounding it represent not stars but the... More »

Large Hadron Collider Gets Closer to Mini-Big Bang

Proton collision shatters record as scientists cheer

(Newser) - The world's largest atom smasher conducted its first experiments at conditions nearing those after the Big Bang today, breaking its own record for high-energy collisions with proton beams crashing into each other at three times more force than ever before. In a milestone for the $10 billion Large Hadron Collider's... More »
