This Is The Coolest Outer Space Animation Ever. It Shows The Crab Supernova Explosion, Happened In 1054,

some of my favourite absolutely SICK facts about the trappist-1 exoplanets: - theyre all very close to one another and to their star, so the length of a year on them varies from 1 to 20 DAYS - since they’re so close, the star appears a lot bigger than our sun from earth, and from one planet you could easily see the rest, some would even appear bigger than the moon from earth. you could literally see the surface of another planet with a naked eye!!! - they’re tidally locked to their star like our moon is locked to earth, meaning only one side of a planet ever faces the star, and on the other side it’s always night. the sun never sets or rises on any of the planets - the star is red, so the sunlight is red/orange, meaning if, for example, plants were to grow there, they could be black and that’s just what we know now, imagine how much cool stuff we have yet to discover about the trappist-1 system

Gravitational waves are real — and that’s a huge f***ing deal!

A century ago, Albert Einstein theorized there was such a thing as a fabric of space and time — that the universe was malleable, and that large objects and events would cause it to bend.

He was right. From studying the signals emanating from the merging of two black holes — have separate masses equal to 36 and 29 suns — scientists with the Laser Interferometer Gravitational-Wave Observatory were able to observe gravitational waves. Their measurements matched expectations of what Einstein predicted in his General Theory of Relativity.

NGC 660. A rare galaxy type, polar ring galaxies have a substantial population of stars, gas, and dust orbiting in rings nearly perpendicular to the plane of a flat galactic disk. Only about a dozen of such galaxies have been discovered

Fun Moments with Our Record Breaking Astronaut

Astronaut Scott Kelly has broken the record for longest time spent in space by a U.S. astronaut. He has spent a cumulative of 383 days in space over the course of four missions. What better way to celebrate than to highlight some of his fun moments on the internet:

A question from the president during a recent TweetChat:

Astronaut Scott Kelly occasionally hosts TweetChats from the International Space Station. During a recent chat, he happened to get a question from someone who lives at 1600 Pennsylvania Avenue! HERE’s a recap from a similar chat from the station. 

Tackling the tough questions during interviews:

During an interview with Katie Couric, Kelly explained what a day on the space station is really like…including the chores he can and can’t do. 

The pros and cons of having roommates:

The International Space Station is an orbiting laboratory where an international crew live, work and conduct valuable research. 

Getting supplies from cargo ships:

Living on the space station requires food, water and supplies. All of these things, plus experiments and other essentials are delivered to the crew via cargo ship. Learn more about our commercial resupply program HERE.
