Intense Bursts of Star Formation Drive Fierce Galactic Winds

Aug 28, 2012 (SPX)

Fierce galactic winds powered by an intense burst of star formation may blow gas right out of massive galaxies, shutting down their ability to make new stars. S...

Halo of neutrinos alters physics of exploding stars

Aug 27, 2012 (SPX)

Sparse halos of neutrinos within the hearts of exploding stars exert a previously unrecognized influence on the physics of the explosion and may alter which ele...

The Milky Way now has a twin or two

Aug 27, 2012 (SPX)

Research presented at the International Astronomical Union General Assembly in Beijing has found the first group of galaxies that is just like ours, a rare sigh...

Supernovae of the same brightness, cut from vastly different cosmic cloth

Aug 27, 2012 (SPX)

Exploding stars called Type 1a supernova are ideal for measuring cosmic distance because they are bright enough to spot across the Universe and have relatively ...

Astronomy project hunts for Chinese helpers

Aug 24, 2012 (XNA)

The online astronomy project - Galaxy Zoo - is searching for Chinese people to help categorize galaxies in the universe. The Zoo, which has no animals but more ...

Astronomers Reassured by Record-breaking Star Formation in Huge Galaxy Cluster

Aug 20, 2012 (SPX)

Until now, evidence for what astronomers suspect happens at the cores of the largest galaxy clusters has been uncomfortably scarce. Theory predicts that cooling...

Phoenix Cluster Sets Record Pace at Forming Stars

Aug 20, 2012 (SPX)

Astronomers have found an extraordinary galaxy cluster, one of the largest objects in the universe, that is breaking several important cosmic records. Observati...

Curious dark nebula seen as never before

Aug 20, 2012 (SPX)

Just as Rene Magritte wrote "This is not a pipe" on his famous painting, this is also not a pipe. It is however a picture of part of a vast dark cloud of inters...

Gamma rays from galactic center could be evidence of dark matter

Aug 15, 2012 (SPX)

Gamma-ray photons seen emanating from the center of the Milky Way galaxy are consistent with the intriguing possibility that dark-matter particles are annihilat...

Evidence further suggests extra-terrestrial origin of quasicrystals

Aug 14, 2012 (SPX)

Results from an expedition to far eastern Russia that set out to find the origin of naturally occurring quasicrystals have provided convincing evidence that the...

Fingering the culprit that polluted the Solar System

Aug 08, 2012 (SPX)

For decades it has been thought that a shock wave from a supernova explosion triggered the formation of our Solar System. According to this theory, the shock wa...

Origins of our solar system probed

Aug 08, 2012 (UPI)

Our solar system may have been kick-started by a shock wave from an exploding star that rippled through a giant rotating cloud of gas, U.S. astronomers say. The...

Physicists celebrate centenary of the discovery of cosmic rays

Aug 07, 2012 (SPX)

A constant shower of subatomic particles rains down from space. A hundred years ago, this "cosmic radiation" was discovered by the Austrian physicist Victor Fra...

A blue whirlpool in The River

Aug 07, 2012 (SPX)

The galaxy NGC 1187 is seen almost face-on, which gives us a good view of its spiral structure. About half a dozen prominent spiral arms can be seen, each conta...

Thin current sheets in space: where the action is

Aug 06, 2012 (SPX)

Much of the exciting action is space is confined to thin boundaries. The Universe is filled with plasma, a charged gas consisting of ions and electrons. Thin sh...

X-rays Discovered From Young Supernova Remnant

Aug 02, 2012 (SPX)

Over fifty years ago, a supernova was discovered in M83, a spiral galaxy about 15 million light years from Earth. Astronomers have used NASA's Chandra X-ray Obs...

Turbulent Relationship among Massive Stars

Aug 02, 2012 (SPX)
