For more resources on all these, go to http://t.co/F0XNvptPCW for detailed explanations of the infographic. We would also like to invite everyone out there who is interested to contribute to our astronomy images gallery. If you take a "share worthy" night-sky picture please send images and comments (including your name and the photo's location) to us at firstname.lastname@example.org. Keep looking up!
