It may be Black Friday for most, but for @NASA it's #BlackHoleFriday! A black hole is a region in space where the pulling force of gravity is so strong that light is not able to escape. Learn more about the basics of black holes >> go.nasa.gov/46pe9Ms

#DYK anyone can do science with @NASA? Thousands of people around the world are helping professionals make discoveries about our planet, our solar system, and our universe at large. Meet three volunteers who participated in citizen science projects >> go.nasa.gov/46wzx2r

Wishing you a safe and happy holiday from #NASAMarshall! 🦃

#OTD in 1973, Skylab 4 astronauts became the first crew to celebrate Thanksgiving in space. The crew spent the majority of their day completing a spacewalk but made up for missing lunch by consuming two meals at dinner time. Check out more >> go.nasa.gov/3GaxOF1

The @Space_Station has encouraged students worldwide to study @NASASTEM for years. The first and longest-running educational outreach program on the space station is ISS Ham Radio - allowing students to talk to astronauts in the orbiting lab. READ MORE >> go.nasa.gov/3sDvpjl
