Welcome to the new, official NASA Tumblr. We’re going to be giving you a regular dose of space here. Follow along and join us as we share information, images and video about our mission of exploration and discovery. First up, check out the moon photobombing Earth in this new animated gif. The far side of the moon, illuminated by the sun, is seen as it crosses between our ‘EPIC’ camera on the Deep Space Climate Observatory (DSCOVR) satellite, and the Earth - one million miles away. Check it out: http://go.nasa.gov/1Dq0IO9

Disclaimer: These are online resources that I have found, They are not meant to be your only source of study, instead you can use them to your enhance your normal study. I don’t know what level these resources are aimed at, but I’ve tried to provide a range for a number of different topics. I don’t study Physics, so I don’t know how accurate these are, or how they relate to course syllabi.
