Mythology stories…

In Hindu mythology, it is said that when Rishis and Philosophers first saw Bhutesh taramandal (Bootes constellation) which is named as Bhutesh by them, actually looked like a shape of a herdsman. Actually, there are many stories associated with Bhutesh. But one of them is that, a bird called Chatak whose thirst is never left unsatisfied by any water resourses on Earth. During monsoon, he waits for water from Swati Nakshatra to satisfy his thirst.

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. 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 509 such different types of Deep Sky Objects observed. Below is the list of 20 brightest Deep Sky Objects:
