Circinus Galaxy
March 16, 2010 — T. A.The Circinus Galaxy, located in the constellation Circinus, approximately 13 million light-years away, is a spiral galaxy first discovered in 1975, notable for its two distinct rings formed by tumultuous gas motions. It is classified as a type 2 Seyfert galaxy; a spiral galaxy having a compact centre and believed to contain a massive black hole,

Whirlpool Nebula (Messier 51) in Canes Venatici
February 23, 2010 — T. A.The Whirlpool Nebula, also known as Messier 51, Arp~85, VV~1 and NGC 5194/NGC 5195, was the first object in the night sky with a spiral structure to be discovered, way back in 1845. It can be found in the constellation Canes Venatici. Messier 51 really consists of two galaxies, NGC 5194 and NGC 5195. NGC 5194 is a large spiral galaxy, while its companion is a smaller barred galaxy.
Messier 51 is not as big and massive as the Milky Way, but it is brighter as a result of being populated by bright, hot, young O and B type stars. It is approximately 31 million light-years distant.

Andromeda Galaxy – Messier 31 (NGC 224)
February 2, 2010 — T. A.Andromeda Galaxy, also known as Messier 31 or NGC 224, is located in the constellation Andromeda, a northern constellation named after the mythical princess Andromeda, who was sacrificed to the sea monster by her parents to appease the gods and rescued by the hero Perseus, who later married her.
The Andromeda Galaxy is the nearest large spiral galaxy to our own, the Milky Way, and it can be seen by the naked eye. Both Andromeda and the Milky Way belong to the Local Group of galaxies, along with Messier 32, Messier 33, Messier 110 and several others.
Andromeda is approximately 2.5 million light-years distant from Earth and has an apparent visual magnitude of 4.4.
