Messier 57 - The Ring Nebula. A brilliant planetary nebula located around 2600 light years away, showing the final phase of a Sun-like star as it reaches the end of its life. As the star expels vast clouds of ionized gas into the cosmos, it leaves behind a white dwarf. Some day billions of years later, our sun will undergo a similar transition
I was surprised at how bright this nebula is. Took only 22 minutes of integration to get this data last night!
