When Stars Explode

New research suggests studying the shape of the aftermath of supernovas (exploding stars) may allow astronomers to figure out what caused them (before the same thing happens to our sun?)

A new study of images from NASA's Chandra X-ray Observatory on supernova remnants (the debris left over from these explosions) shows that the symmetry...

Death Star on the Way?

Australian astronomers are keeping an eye on an exploding star they call WR104 that could end all life on earth. Before you say it couldn't happen, note that a smaller version of this has happened here before.

This star is actually TWO stars and it's getting ready to explode at any time. When a binary start like this one collapses into a...

Why the New World was So Empty

when the Europeans arrived - Debris from an exploding star (a supernova) wiped out mostof the large animals (including humans) living in North America around 13,000 years ago. This is one reason why the continent was so empty, despite being so verdant, when the Europeans arrived. If this hadn't happened, they would have had to...

Death Star

There's a binary solar system, consisting of two suns, out there, rotating and twisting through space. If it comes near us, it may shoot out a beam of gamma rays that could eliminate all life on this planet in an instant.

The solar system was first spotted 8 years ago by Australian astronomers. One of the suns is a highly unstable star...

Astronomers have spotted a star that is about to explode?a supernova. Could this ever happen to OUR sun?

In BBC News, Roland Pease reports that astronomers saw the star "RS Ophiuchi? flare up around 6 months ago, suddenly becoming a thousand times brighter than normal. This could mean that, somewhere in the universe, a world like ours is...

Supernova Wipeout

While doing research for a term paper, Karin Sandstrom, a student at Harvard University, discovered a star in our own backyard that is on the brink of exploding in a supernova. It?s so close that if it were to blow up before moving away from us, it could wipe out life on Earth.

Supernova Ended Life on Earth

An exploding star may have destroyed part of Earth?s protective ozone layer two million years ago, killing off some forms of ancient marine life. Narciso Benitez, of Johns Hopkins University, says the ?missing smoking gun? of a mass extinction that occurred far in the past was the revelation that a stellar cluster with many large, short-lived...
