Hyperactive Hartley 2 has a split history, comet-exploring spacecraft finds Posted: 04 Oct 2011 10:28 AM PDT The latest analysis of data from NASA's Deep Impact spacecraft shows that comet 103P/Hartley 2 is hyperactive in terms of the material it spews out, compared to the other comets observed up close to date. The comet also shows surprising diversity - ice on the comet's sunlit surface is found in patches that are isolated from areas of dust. In addition, one lobe of the dog-bone shaped comet may have lost much more of the primordial material from the formation of the comet than the other, suggesting that Hartley 2 was originally two comets that came together in a gentle collision.

Titanic jigsaw challenge: Piecing together a global color map of Saturn’s largest moon Posted: 04 Oct 2011 10:28 AM PDT An international team has pieced together images gathered over six years by the Cassini mission to create a global mosaic of the surface of Titan.

Kepler spacecraft discovers new multi-planet solar system Posted: 04 Oct 2011 10:28 AM PDT A team of researchers has used NASA's Kepler spacecraft to discover an unusual multiple-planet system containing a super-Earth and two Neptune-sized planets orbiting in resonance with each other.

A new technique for understanding quantum effects in water Posted: 04 Oct 2011 10:27 AM PDT The use of oxygen isotope substitution will lead to more accurate structural modeling of oxide materials found in everything from biological processes to electronic devices.

Advance offers new opportunities in chemistry education, research Posted: 04 Oct 2011 10:25 AM PDT Researchers have created a new, unifying method to describe a basic chemical concept called "electronegativity," first described almost 80 years ago by Linus Pauling and part of the work that led to his receiving the Nobel Prize. The new system offers simplicity of understanding that should rewrite high school and college chemistry textbooks around the world, even as it opens important new avenues in materials and chemical research.

Physicists move one step closer to quantum computer Posted: 04 Oct 2011 09:36 AM PDT Physicists have created a tiny "electron superhighway" that could one day be useful for building a quantum computer -- a new type of computer that will use quantum particles in place of the digital transistors found in today's microchips. Researchers now describe how to make a "topological insulator," a much-sought device that could help physicists create elusive pairs of quantum particles that are particularly useful for storing information.

2011 Nobel Prize in Physics: Discovery of expanding universe by observing distant supernovae Posted: 04 Oct 2011 06:17 AM PDT The Royal Swedish Academy of Sciences has awarded the Nobel Prize in Physics for 2011 to Saul Perlmutter, Brian P. Schmidt and Adam G. Riess, for the discovery of the accelerating expansion of the universe through observations of distant supernovae.
