Hubble sees light and dust in a nearby starburst galaxy

Posted: 05 Apr 2013 11:39 AM PDT

The Hubble Space Telescope has taken an image of a small, sparkling hook in the dark sky -- a beautiful object is known as J082354.96+280621.6, or J082354.96 for short. It is a starburst galaxy, so named because of the incredibly (and unusually) high rate of star formation occurring within it.

Mapping the chemistry needed for life at Jupiter's moon Europa

Posted: 05 Apr 2013 11:34 AM PDT

A new paper led by a NASA researcher shows that hydrogen peroxide is abundant across much of the surface of Jupiter's moon Europa. The authors argue that if the peroxide on the surface of Europa mixes into the ocean below, it could be an important energy supply for simple forms of life, if life were to exist there.

Material turns 'schizophrenic' on way to superconductivity

Posted: 05 Apr 2013 07:48 AM PDT

Physicists on the hunt for the origins of high-temperature superconductivity have published new findings this week about a material that becomes "schizophrenic" -- simultaneously exhibiting the characteristics of both a metallic conductor and an insulator. In a theoretical analysis, researchers offer an explanation for a strange series of observations described earlier this year by researchers at the Stanford Linear Accelerator Center in Menlo Park, Calif.

Dead star warps light of companion red star, astronomers say

Posted: 05 Apr 2013 06:47 AM PDT

Astronomers have observed the effects of a dead star bending the light of its companion red star. The findings are among the first detections of this effect -- a result predicted by Einstein's theory of general relativity -- in binary, or double, star systems.

Breakthrough in chemical crystallography

Scientists have made a fundamental breakthrough in single-crystal X-ray analysis, the most powerful method for molecular structure determination.
