Question

Where is the subject of astronomy?

I dont think there is one on here...

There are none. You can try asking an Admin about private study groups that have already be created. There may be one made for astronomy. For now you can post your astronomy questions in physics since they are closely related.

There is an astronomy group, but it's pretty inactive http://openstudy.com/study#/groups/astronomy
