The Orion Nebula, also known as Messier 42, is a prominent nebula located in the constellation Orion. It is one of the brightest nebulae and can be seen with the naked eye under dark skies.

The Crab Nebula is the result of a supernova explosion that was observed by astronomers in 1054 AD. The remnant of the explosion is a pulsar, a rapidly rotating neutron star, which emits pulses of radiation.

The Helix Nebula, also known as NGC 7293, is a planetary nebula located in the constellation Aquarius. It is known for its spiral structure and its resemblance to an 'Eye of God' when viewed through a telescope.

The Pillars of Creation are composed primarily of molecular hydrogen, which is a form of hydrogen gas consisting of two hydrogen atoms bonded together. They are located within the Eagle Nebula, also known as Messier 16.

The Horsehead Nebula, also known as Barnard 33, is a dark nebula located in the constellation Orion. It is known for its distinctive shape, which resembles a horse's head when viewed through a telescope.

The Triangulum Galaxy, also known as Messier 33, is a spiral galaxy located in the constellation Triangulum. It is the third closest major galaxy to the Milky Way and is visible to the naked eye under dark skies.

The Tarantula Nebula, also known as 30 Doradus, is a large emission nebula located in the Large Magellanic Cloud, a satellite galaxy of the Milky Way. It is one of the most active star-forming regions in the Local Group of galaxies.

The Butterfly Nebula, also known as NGC 6302, is a bipolar planetary nebula located in the constellation Scorpius. It is known for its distinctive 'Butterfly Wings' appearance, which is created by two lobes of gas ejected from a dying star.

The Lagoon Nebula, also known as Messier 8, is a large emission nebula located in the constellation Sagittarius. It is one of the most prominent nebulae in the Milky Way and is visible to the naked eye under dark skies.

The Cat's Eye Nebula, also known as NGC 6543, is a planetary nebula located in the constellation Draco. It is known for its distinctive 'Cat's Eye' appearance, which is created by a dying star surrounded by a ring of gas.

The Ghost Nebula, also known as IC 63, is a supernova remnant located in the constellation Cepheus. It is known for its faint, diffuse appearance, which resembles a ghost when viewed through a telescope.

The Veil Nebula, also known as NGC 6960, is a supernova remnant located in the constellation Cygnus. It is known for its distinctive 'Veil' appearance, which is created by the expanding shock wave from a supernova explosion.

The Ring Nebula, also known as Messier 57, is a planetary nebula located in the constellation Lyra. It is known for its distinctive ring-like structure, which is created by a dying star surrounded by a ring of gas.

The Southern Pinwheel Nebula, also known as Messier 83, is a barred spiral galaxy located in the constellation Hydra. It is known for its distinctive 'Southern Pinwheel' appearance, which is created by its spiral arms and a central bar.

The Whirlpool Galaxy, also known as Messier 51, is a spiral galaxy located in the constellation Canes Venatici. It is known for its distinctive spiral structure, which resembles a whirlpool when viewed through a telescope.
