Giant Cosmic Lens Reveals Secrets of Distant Galaxy
April 3, 2003 at 5:49 pm | News Release

An international team of astronomers has discovered that a young galaxy had a central disk of gas in which hundreds of new stars were being born every year — at a time when the Universe was only a fraction of its current age.

Pulsar Bursts Coming From Beachball-Sized Structures
March 12, 2003 at 5:43 pm | News Release

In a major breakthrough for understanding what one of them calls ‘the most exotic environment in the Universe,’ a team of astronomers has discovered that powerful radio bursts in pulsars are generated by structures as small as a beach ball.

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.
