Artist's Conception of ALMA Array in Compact Configuration.
U.S. and European ALMA Partners Sign Agreement
February 25, 2003 at 5:30 pm | Announcement

Dr Rita Colwell, director of the U.S. National Science Foundation, and Dr Catherine Cesarsky, director general of the European Southern Observatory, today signed a historic agreement jointly to construct and operate ALMA, the Atacama Large Millimeter Array, the world’s largest and most powerful radio telescope operating at millimeter and sub-millimeter wavelengths.

Path of Microquasar through the Milky Way Galaxy
Astronomers Trace Microquasar’s Path Back in Time
January 27, 2003 at 5:16 pm | News Release

Astronomers have traced the orbit through our Milky Way Galaxy of a voracious neutron star and a companion star it is cannibalizing, and conclude that the pair joined more than 30 million years ago and probably were catapulted out of a cluster of stars far from the Galaxy’s center.

Surprising Image Revises Understanding Of Dwarf Galaxies
January 8, 2003 at 5:13 pm | News Release

An intensive study of a neighboring dwarf galaxy has surprised astronomers by showing that most of its molecular gas — the raw material for new stars — is scattered among clumps in the galaxy’s outskirts, not near its center as they expected.

Path of T Tauri Component Sb
Young Star Probably Ejected From Triple System
January 8, 2003 at 4:54 pm | News Release

Astronomers analyzing nearly 20 years of data from the National Science Foundation’s Very Large Array radio telescope have discovered that a small star in a multiple-star system in the constellation Taurus probably has been ejected from the system after a close encounter with one of the system’s more-massive components, presumed to be a compact double star. This is the first time any such event has been observed.

Giant Radio Jet Coming From Wrong Kind of Galaxy
January 8, 2003 at 4:51 pm | News Release

Giant jets of subatomic particles moving at nearly the speed of light have been found coming from thousands of galaxies across the Universe, but always from elliptical galaxies or galaxies in the process of merging — until now.

Speed of Gravity Measured for First Time
January 7, 2003 at 4:41 pm | News Release

Taking advantage of a rare cosmic alignment, scientists have made the first measurement of the speed at which the force of gravity propagates, giving a numerical value to one of the last unmeasured fundamental constants of physics.
