Western Veil Nebula
Western Veil Nebula
This is the Veil Nebula taken near Cygnus region and sits about 2100 light years from earth. This view back in time shows the filaments and thin strands of ionized hydrogen (green) and oxygen (blue).
This is the left overs of a star 20 times the mass of our sun that went supernova about 10,000 years ago.
If you can find the Cygnus Cross in the sky, look to the left of the cross and off that tip is this nebula. This is also known as the western veil nebula, while another large eastern veil nebula sits just under this one.
