Reuters: Hubble Sees Massive Star Nursery in Nearby Galaxy
WASHINGTON (Reuters) - Glowing gold at its center and
ringed by a purplish halo, a nearby galaxy holds a vast, stellar
nursery with dusty and clean areas for newborn stars, a new
Hubble Space Telescope (news - web sites) image showed on
Thursday. The new composite picture of galaxy NGC 1512 was made
with light at various wavelengths, from infrared to ultraviolet,
and shows a monster area -- 2,400 light-years across -- filled
with clusters of infant stars. A light-year is about 6 trillion miles, the distance light travels
in a year. The galaxy itself is about 30 million light-years away,
relatively close by cosmic standards. Israeli and U.S. researchers studying the image found that in
NGC 1512, infant stars exist in both dusty and clean
environments, NASA and the European
Space Agency said in a statement. The clean clusters are readily seen in ultraviolet and visible
light, appearing as bright, blue clumps in the image, while the
dusty clusters are revealed only by the glow of the gas clouds
in which they are hidden, as detected in red and infrared
wavelengths by the Hubble cameras. The researchers' results will be published in the June issue of
the Astronomical Journal
