OSIRIS-REx arrived at asteroid Bennu this week! It will stay in orbit to do a complete survey of the asteroid. But even cooler, it will get so close to the surface it will touch Bennu briefly and use a puff of hydrogen to dislodge surface material, that it will then collect. After that, OSIRIS-REx heads back to Earth to deliver the sample!
Here is a really cool video on how this little orbiter got to Bennu and detailing its mission.
InSight landed safely on Mars yesterday!! This little guy isn’t a rover, but a lander that will be studying seismic activity on the red planet.

Happy Thanksgiving, everyone!!!
So this is pretty cool! Researchers just discovered a very large, but very dim dwarf galaxy right in our own backyard! There are some questions as to how this mysterious “ghost galaxy” is able to be so large and so faint (usually galaxies shrink as they lose stars).

Pluto should have done his research.
On Oct 31, 2015 scientists used radar imaging to photograph a little dead comet. Much to their surprise, it looked quite a lot like a skull! Due to that and the timing, they nicknamed it Death Comet.
Death Comet will swing by us again this year (albeit a little later than last time).

Happy Halloween, all!!! 💀🎃
While we’ve never seen one, theoretically moons orbiting moons is possible under the right circumstances. But what would we call them?? And why is it so difficult to come up with names in astronomy anyway?
Giant ice spikes would make for a rough landing if we ever make it to Europa. You can read more about this study here: https://phys.org/news/2018-10-giant-jagged-ice-spikes-jupiter.html
