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.

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.
