Space is not cold. Temperature describes the motion of particles. And space is mostly… not particles. An object in space can get extremely hot in sunlight 🔥 and extremely cold ❄ in shadow because there's almost nothing around it to transfer heat. “Space is cold” is convenient shorthand. 🧪

Happy Bi Visibility Day and Sea Otter Awareness Week to everyone who refuses to choose between two things and also holds hands so they don't drift apart. 🩷💜💙🦦

A lot of people don't know this, but when you brush a cat, you are legally required to show them the wad of cat hair that came off of them and tell them "this is enough for another whole cat"

I think all of Silicon Valley is awake after that one! Tell the USGS if you felt the earthquake near Boulder Creek earthquake.usgs.gov/earthquakes/...

Yeah, I’m awake now. That was wild. Biggest quake I’ve felt in years.

From all of us at the SETI Institute, we wish godspeed to Reid, Victor, Christina, and Jeremy for the safe and successful completion of the #ArtemisII mission. This is a profound moment not only for NASA but for all of humanity, and our thoughts are with you. Congratulations on a successful launch!

Karman line reached!

"Humanity's next great voyage begins." Godspeed, Artemis II.

Oh. Oh. I am tearing up. I thought I was immune, but I was wrong. We are go for launch.
