Astronomers Find Hundreds of Young, Distant Galaxy Clusters

Astronomers have found the largest number of the most distant, youngest galaxy clusters yet, a feat that will help them observe the developing universe when it was less than half its current age and still in its formative ...

Distant ball of dust not dusty enough

One of the youngest supernova remnants known, a glowing red ball of dust created by the explosion 1,000 years ago of a supermassive star in a nearby galaxy, the Small Magellanic Cloud, exhibits the same problem as exploding ...

Negative Index Materials: From Theory to Reality

Kent State University researchers are leading a team of scientists from eight institutions, who have been awarded a $5.5 million Multidisciplinary University Research Initiative (MURI) from the Air Force Office of Scientific ...

The Magnetic Nature of a Mysterious Cosmic X-ray Emitter

Our Sun has its explosive flares and spots and high speed wind, but it is a placid star compared to some. Stars that are much more massive live fast and die young, with blue-white, intensely hot surfaces that emit energy ...

Our Ancestors Survived 'Snowball Earth'

Ancient human fossils find modern virtual home

First discovered 150 years ago, Neanderthals have been studied more widely than any other form of human. Thanks to a new interactive inventory and online catalogue developed in Europe, scientists worldwide can now probe the ...

Physicists generate ball-lightning in the lab

Scientists in the joint study group of Max-Planck-Institut für Plasmaphysik and Berlin’s Humboldt University have generated ball-lightning in the laboratory - or, to be more precise, ball-lightning-like plasma clouds. ...

Marine technology inspired by dolphins' speed

According to Gray’s paradox, dolphins swim faster than they should be able to. Since Gray, scientists have discovered flaws in the details of the paradox, although some explanations of these creatures’ aquatic grace have ...
