The moon formed when Theia hit the earth. The surface of the moon is mostly material from the #earth with the same isotopes... but if we could drill into the moon... we could find some of #Theia according to some models of the collision.
Theia is still here! Just covered in a super thick earthy sweater.
I don't know why I find this so exciting-- it's probably not going to be anything shocking...
I guess Theia always seemed... vanished into the deep past. But Theia remains. #musings #moon
"Oh give me a focus,
Where the gravitons focus,
And the three-body problem is solved,
Where the microwaves play,
Down at three degrees 'kay',
And the cold-virus never evolved"
Chorus:
"Home, home on Lagrange..."
etc.

my favorite bit of Lagrange nedery is DSCOVR, which stays near the sunward Sun-Earth Lagrange (L1) point, and (among other instruments) has a camera that takes regular pictures of the sun-facing side of the earth.

sometimes the Moon passes between the Earth and DSCOVR, and you see this:
