Aurora on Saturn.

The Wow! signal. 

A signal sequence that lasted for 72 seconds in 1977 but has never been seen again. The signal appeared to come from a globular cluster in the Sagittarius constellation, but to this day no definite answer for where the signal originated can be given.  

Spectacular!

VIMOS’s last embrace

A cosmic blossom

IC 5148 is a beautiful planetary nebula located some 3000 light-years away in the constellation of Grus (The Crane). The nebula has a diameter of a couple of light-years, and it is still growing at over 50 kilometres per second — one of the fastest expanding planetary nebulae known. The term “planetary nebula” arose in the 19th century, when the first observations of such objects — through the small telescopes available at the time — looked somewhat like giant planets. Although the name stuck, it represents the expanding shell of gas ejected from old red giant stars late in their lives.

And now this one resembles a lovely blossom with layered petals.

NASA’s Most Shocking Image

NASA is the coolest thing that’s ever happened.

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 the naked eye!!! - they’re probably 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
