What is cool down? Where can I read more about this


Webb team keeps a blog here, they discuss if you scroll down a bit...


Bit on how temperatures work in space....
"Quick heat transfer requires contact or air, both lacking in space. As a result objects cool very slowly through the much slower mechanism of thermal radiation."

Being NASA stuff, going to post here instead of make a whole new thread.
But I saw that Eugene Parker, who figured out that the sun emits solar wind and got to watch in 2018 the rocket takeoff with the probe in his name that flew close to the sun. He just died yesterday (March 17th) at 94. Oddly, my Grandma died now 7 years ago on March 17...and my Grandpa's birthday is now today and he is 94.
