Suzaku 'post-mortem' yields insight into Kepler's supernova

(Phys.org) —An exploding star observed in 1604 by the German astronomer Johannes Kepler held a greater fraction of heavy elements than the sun, according to an analysis of X-ray observations from the Japan-led Suzaku satellite. ...

Berkeley Lab scientists read the cosmic writing on the wall

Thanks to a supersensitive space telescope and some sophisticated supercomputing, scientists from the international Planck collaboration have made the closest reading yet of the most ancient story in our universe: the cosmic ...

Prof explores universe through gravity lens studies

(Phys.org) -- The National Science Foundation recently awarded Dr. Mustapha Ishak-Boushaki, associate professor of physics at UT Dallas, a $222,000 research grant for his investigations of the gravitational lensing technique ...

Dark matter mystery deepens

(PhysOrg.com) -- Like all galaxies, our Milky Way is home to a strange substance called dark matter. Dark matter is invisible, betraying its presence only through its gravitational pull. Without dark matter holding them together, ...

The most massive distant object known

(PhysOrg.com) -- Galaxies often occur in groups. Our own Milky Way galaxy, for example, and its local neighborhood with about fifty galaxies are at the edge of the Virgo Cluster, a collection of somewhere between 1200 and ...

Gas rich galaxies confirm prediction of modified gravity theory

(PhysOrg.com) -- Recent data for gas rich galaxies precisely match predictions of a modified theory of gravity know as MOND according to a new analysis by University of Maryland Astronomy Professor Stacy McGaugh. This -- ...
