A quick widefield capture of something interesting that one doesn’t have the opportunity to see often. Comet C/2016 M1 (PANSTARRS), passing between the constellation Norma and Ara (close to the Open Star Cluster NGC 6152) at 01:00 on 15 July 2018.

The comet doesn’t have much of a tail at the moment, but has a beautiful green coma.

About the Milky Way, and Earth’s place within it:
The Milky Way Galaxy is estimated to have over 400 billion stars. Stars are suns, and just like in our Solar System, many of the stars have planets with moons orbiting them. Our sun is a middle aged Yellow Dwarf star, located in the Orion Arm (or Orion Spur) of the Milky Way Galaxy. It’s a minor side spiral arm, located between two larger arms of the Milky Way Galaxy’s spiral. The Milky Way is merely one mid-sized barred spiral Galaxy, amongst over 100 billion other Galaxies in the observable Universe. When we look up at the night sky from Earth, we see a glimpse of the Carina-Sagittarius Arm of the Milky Way Galaxy. It takes about 250 million years for the Milky Way Galaxy’s spiral arms to complete one rotation.

The size, distance and age of the Universe is far beyond human comprehension. The known Universe is estimated to contain over One Billion Trillion stars.
