Explanation:
The big, beautiful Andromeda Galaxy,
aka M31, is a spiral galaxy a
mere 2.5 million light-years away.
Two space-based observatories have combined to produce
this intriguing composite image of Andromeda,
at wavelengths outside the
visible spectrum.
The remarkable view
follows the locations of this galaxy's
once and future stars.
In reddish hues, image data from the large
Herschel infrared
observatory traces enormous lanes of dust,
warmed by stars, sweeping along Andromeda's spiral arms.
The dust, in conjunction with the galaxy's interstellar gas,
comprises the raw material for future
star formation.
X-ray data from the XMM-Newton
observatory in blue
pinpoint Andromeda's X-ray binary
star systems.
These systems likely contain neutron stars or stellar mass
black holes that represent final stages in stellar evolution.
More than twice the size of our own Milky Way,
the Andromeda Galaxy is over 200,000 light-years across.
