Explanation:
Beautiful island universe
Messier 94 lies
a mere 15 million light-years
distant in the northern constellation of the hunting dogs,
Canes
Venatici.
A popular target for earth-based astronomers,
the face-on spiral galaxy is about 30,000 light-years across,
with spiral arms sweeping through the
outskirts of its broad disk.
But this Hubble
Space Telescope field of view spans about
7,000 light-years or so across M94's central region.
The sharp close-up examines the galaxy's compact,
bright nucleus and prominent inner dust lanes,
surrounded by a remarkable bluish ring of young,
massive stars.
The massive stars in the ring are all likely less than 10 million
years old, indicating the galaxy experienced a well-defined
era of rapid star formation.
As a result, while the small, bright nucleus is typical of the
Seyfert
class of active galaxies, M94 is also known as a
starburst galaxy.
Because M94 is relatively nearby, astronomers can explore
in detail
reasons for the galaxy's burst of star formation.
