Explanation:
The Whirlpool Galaxy is a classic spiral galaxy.
At only 30 million
light years distant and fully 60 thousand light years across,
M51, also known as
NGC 5194, is one of the brightest and most
picturesque galaxies on the sky.
The featured image
is a digital combination of images taken in different colors by the Earth-orbiting
Hubble Space Telescope,
highlighting many sharp features.
Anyone with a good pair of
binoculars,
however, can see this
Whirlpool toward the constellation
of the Hunting Dogs
(Canes Venatici).
M51 is a
spiral galaxy of type Sc
and is the dominant member of a
whole group of galaxies.
Astronomers
speculate that M51's
spiral structure is primarily due to its
gravitational interaction with the
smaller galaxy on the image left.
