Explanation:
Star formation occurs at a faster pace in
M82 --
a galaxy with about ten times the rate of massive star birth (and death) compared
to our
Milky Way.
Winds from massive stars and blasts from
supernova explosions have created a billowing cloud of
expanding gas from this remarkable
starburst galaxy.
The
above scientifically
color-coded image highlights the complexity and
origin of the plume by combining a wide field image from the
WIYN Telescope in
Arizona
with a smaller high-resolution image from the orbiting
Hubble Space Telescope.
M82's aspect in optical pictures has led to its popular moniker, the
Cigar Galaxy.
M82's burst of star formation was likely triggered a
mere 100 million years ago in the latest of a
series of bouts with neighboring large galaxy
M81.
