New Discovery Sheds Light on the Ecosystem of Young Galaxies

Research may help explain how galaxies take in matter and give off energetic radiation.


Astronomers Capture Cosmic Jet Firing Up

Using X-ray, radio, and gamma-ray observations of a distant galaxy, a multinational team of astrophysicists has seen perhaps the first live instance of the turning on of a powerful jet from a supermassive black hole.


Center for Communicating Science Holds First Conference

University faculty and administrators from 20 states gathered at Stony Brook in June for an innovative, four-day conference dedicated to improving the way scientists communicate with the public.


New Data Still Have Scientists in Dark Over Dark Matter

A dark-matter experiment deep in the Soudan mine of Minnesota now has detected a seasonal signal variation similar to one an Italian experiment has been reporting for more than a decade.


President Obama Meets U.S. Laureates of 2010 Kavli Prizes

At the White House, President Barack Obama met the seven U.S. recipients of the 2010 Kavli Prizes to recognize and honor their seminal contributions to the three fields for which the Prizes are awarded -- astrophysics, nanoscience and neuroscience.
