hubble
reveals the heart of the whirlpool galaxy
April
5, 2001 -- New pictures from the Hubble telescope are giving astronomers a detailed
view of the Whirlpool galaxy's spiral arms and dust clouds, which are the birth
sites of massive and luminous stars. This galaxy, also called M51 or NGC 5194,
is having a close encounter with a nearby companion galaxy, NGC 5195, just off
the upper edge of this image. The companion's gravitational influence is triggering
star formation in the Whirlpool, as seen by the numerous clusters of bright, young
stars [highlighted in red].
