X-ray Clues Reveal Destroyed Planet

Female Astronauts in History:

Valentina Tereshkova became the first woman to go to space in 1963.

She orbited the Earth 48 times, spent almost three days in space, is the only woman to have been on a solo space mission and is the last surviving Vostok programme cosmonaut.

Hilariously funny that the guy known for wandering off without warning to look at birds was allowed to do this

And congrats to Mercury for being Tumblr's least favorite planet!

This one was expected, I love Mercury but it just looks (and is tbh) a little boring. Still a cool planet, love the craters!!

Supernova 1987A

The remnant of Supernova 1987A, located in a neighboring galaxy called the Large Magellanic Cloud, appears at the center of this image. The red, gaseous clouds that surround it fuel a firestorm of new star formation.

I will be honest, I just thought this was my astigmatism acting up the first time I saw it.
