The Helix Nebula, also known as NGC 7293, is a large
planetary nebula located in the constellation Aquarius.
Discovered in 1824, this is one of the closest planetary
nebula to us here on Earth.

reflector telescope. The moon on the right is Io.
The Crescent Nebula is an emission
nebula in the constellation Cygnus. It is about 5000
light-years away from us. The nebula is the result of a
strong stellar wind from a Wolf-Rayet star colliging with
and energizing the slower moving wind ejected by the star
when it became a red giant some 400,000 years ago.
The Whirlpool Galaxy, also known as M51, is actually a pair
of interacting galaxies about 23 million light-years away
from us. There have been two distinct supernova explosion
in the Whirlpool in the last ten years.
The Globular Cluster in Hercules
The great globular cluster in Hercules, also known as M13,
the brightest and prettiest globular cluster visible to
observers in the northern hemisphere.
The Crab Nebula, also known as M1, is a supernova remnant
from the supernova explosion of 1054AD. At the center of
the nebula lies the Crab Pulsar, which is a neutron star
remnant of the exploded supernova.
The Orion Nebula, also known as M42, is the bright deepsky
nebula visible to observers in the northern hemisphere. It
is a star-birth region where interstellar gas is in the
process of condensing and forming new stars.
