Greetings and welcome back, Earthlings!
The NASA OSIRIS-REx probe has been having a lot of fun twirling around the mysterious asteroid, Bennu! When it came to its closest approach yet, Bennu did something that no one expected!
Not water per se, but rather spitting pieces of rubble out into space!
What does this mean? We are not 100% certain…
But what we do know…Bennu the Asteroid is ACTIVE!
This is not like a comet where the ice and rubble heat up and vaporize, releasing bits of rubble. NO! This debris is larger than expected, quite a few dozen at once!
With the surface also being discovered to be much more rough, this process of spitting out pieces of rock into space is all the more puzzling!
Thank you for reading and come back next week for a look at the Event Horizon Telescope!
