Massive Black Holes "Switched On" By Galaxy Collision

New research looks to explain how galaxies weighing in at about 300 million solar masses become "active."


Names of the 2010 Kavli Prize Winners Announced

Eight scientists whose discoveries have dramatically expanded human understanding in the fields of astrophysics, nanoscience and neuroscience have been recognised with the award of the million-dollar Kavli Prizes.


Unique Eclipsing Binary Star System Discovered by UCSB Astrophysicists

UC Santa Barbara Astrophysicists are the first to identify two white dwarf stars in an eclipsing binary system, allowing for the first direct radius measurement of a rare white dwarf.


Einstein's Theory Fights Off Challengers

Two new and independent studies have put Einstein's General Theory of Relativity to the test like never before. These results, made using NASA's Chandra X-ray Observatory, show Einstein's theory is still the best game in town.


Michael Turner Named Director of Kavli Institute for Cosmological Physics

The University of Chicago has named Michael S. Turner as director of its Kavli Institute for Cosmological Physics, effective March 29, in an ongoing commitment to probing some of the most puzzling scientific questions about the origin and evolution of the universe.


Fermi Telescope Probes "Dragons" of the Gamma-ray Sky

A new study of gamma rays shows that less than a third of the emissions arise from black-hole-powered jets from active galaxies.


Astronomically Large Lenses Measure the Age and Size of the Universe

Researchers have a newly precise way to measure the size and age of the universe and how rapidly it is expanding, on a par with other techniques.


Massive Planet is Being Torn Apart, Providing Opportunity to Watch a Planetary “Death March”

A massive planet outside our Solar System is being distorted and destroyed by its host star, a finding that helps explain the unexpectedly large size of the planet, WASP-12b.
