APOD 3.7

    I was recently looking at the APOD titled Cometary Globule CG4. This is a very faint globule in the southern sky positioned about 1,300 light years away. It is near the constellation Puppis and this nebula's tail is about 8 light year long with enough material in it to form several stars like the sun. It's amazing that something could appear so small but in reality be so big. Its still unknown how its form came into being but its  tail came from the remains of a Vela supernova.
