what do u think is one of the prettiest or coolest things in space??

Neutron stars and their variants (i.e. magnetars, pulsars). Really bizarre and very interesting objects.

molecular clouds! i love how diverse they are in color and size and shape:))

Supernova's. All the colors and clouds are so pretty

Constellations, They aren’t much but it’s just cool to look into the scattered expanse of they sky and find shapes and stories left from generations ago. Plus they can help tell time and direction.
