Fig. 1: Optical (left) and near-infrared (right) comparison between mass (M) and mass-to-light ratio (M/L). The vector shows the evolution of M/L over time. LIRGs (open circles) appear very different in both panels, while non-LIRGs and ellipticals remain the same. read more

In an attempt to explain away invisible dark matter and dark energy, some theorists have offered new theories of gravity that try to improve on Einstein’s General Theory of Relativity. A new study inspired by the work of a Berkeley Lab cosmologist indicates that at least one of these new theories is wrong.

ESA PR 2010-04 The heads of the International Space Station (ISS) agencies from Canada, Europe, Japan, Russia and the United States met in Tokyo, Japan, on 11 March 2010, to review ISS cooperation. With the assembly of the ISS nearing completion and the capability to support a full-time crew of six established, they noted the outstanding opportunities now offered by the ISS for on-orbit research and for discovery including the operation and management of the world’s largest international space complex.

Astronomers have used NASA's Spitzer Space Telescope rather like a doctor's stethoscope to listen in on the "heartbeat" of star formation in our galaxy, a finding that will help trace the "life" of the Milky Way and other galaxies.

An international panel of experts has ruled in favor of the theory proposed in 1980 by the late Berkeley Lab physicist Luis Alvarez and his son Walter, a UC Berkeley geologist, that a large asteroid struck the earth 65 million years ago, triggering the extinction of the dinosaurs.

Astronomers using the W. M. Keck Observatory have identified the smallest known binary system to date. The system, called HM Cancri, consists of two dead stars that revolve around each other in 5.4 minutes, by far the shortest known orbital period of any pair of stars. The team, led by Gijs Roelofs of the Harvard-Smithsonian Center of Astrophysics, used the 10-meter Keck I telescope with its Low Resolution Imaging Spectrograph to study the velocity changes in the spectral lines in the light of HM Cancri. They observed that as the stars orbited each other, the system’s spectral lines shifted…
