Hi, my Name is Beka (@bmamukashvili_)and I live in Georgia, Tbilisi. This is the photo that I've taken in Abastumani, at some 1500m altitude.
I am sure everyone of you does know this object. It is Andromeda Galaxy (M31) which is located 2 million light years away from us. Scientists estimate that in 2-3 billion years from now, it will collide with our Milky Way galaxy and one, bigger galaxy will form.
This object is very important to me. Until Edwin Hubble, we thought that the whole universe was our Milky Way. Older name of this galaxy was Great Andromeda Nebula. Yes, we thought that this separate galaxy was nebula in our own galaxy.
Edwin Hubble discovered that M31 really was a separate galaxy, far, far away from us. He also discovered other galaxies too and measured their red shift and concluded that our universe was expanding. The whole new era in astronomy was born. Our imagination on the universe's size grew from one galaxy to 200 billion galaxies!
We now know that there are approximately 2 trillion galaxy in the visible universe.
I had been collecting the light of M31 for about 3 hours, from old Soviet observatory, in Abastumani, Georgia. It was very thrilling moment in my life to capture Andromeda because I knew that this is an object which changed our understanding about the universe!
