Deep Sky Objects

Andromeda Galaxy

Andromeda's Cluster || Mayall ii || Globular Cluster

Blue Snowball Nebula || Planetary Nebula

All the stars that we see naked eyes, all belong to our own, Milky way galaxy (Akash Ganga Tara Vishv). Bright stars can be seen naked eye and faint one through telescope. But the curtain of sky that we see in 2D is actually a huge universe we are talking about, with 3 dimension. There are many nebulous objects visible in every constellations, they differ widely by distances and nature. Many are different types of nebulae like Emission Nebula, Reflecting Nebula, Absorption Nebula, Star Birth Nebula, Supernova Remnants (SNR) and Open Stars cluster which are within the disk of our own Milky Way galaxy. Globular cluster are also found, which are in the halo of our galaxy and some most distant objects like galaxies are also visible through telescope. Such objects are defined as “Deep Sky Objects”.

In this constellation there are 198 such different types of Deep Sky Objects observed. Out of these one is very interesting and; famous Andromeda spiral galaxy visible even through naked eye. It is the farthest naked eye object visible at 2.2 million light year distance.
