Do one million stars confirm dark matter is the major mass of the Milky Way Galaxy?

Johns Hopkins Univ. news release dated 1/11/06

SCIENTISTS "RAVE-ING" ABOUT MOST AMBITIOUS STAR SURVEY EVER

An international team of astronomers today announced the first results from
the Radial Velocity Experiment, an ambitious all-sky spectroscopic survey
aimed at measuring the speed, temperature, surface gravity and composition
of up to a million stars passing near the sun.

Those first results from the project, known for short as RAVE, confirm that
dark matter dominates the total mass of our home galaxy, the Milky Way, team
members at The Johns Hopkins University and elsewhere said. The full survey
promises to yield a new, detailed understanding of the origins of the
galaxy, they said.

The results were released at the American Astronomical Society's 207th
meeting in Washington, D.C.
