Have you ever seen a star in its dying moments? Thanks to Hubble, now you do! 🔭 This is the Egg Nebula (CRL2688), a protoplanetary nebula ~3,000 light-years away. I processed 2016 Hubble data for the first image; 2002 for the second, which is more like a zoom into it. HD: flic.kr/p/2qLkMCK

Did Earth capture the Moon? Darren M. Williams, et. al. has revived the capture hypothesis in his recent paper H/t Tony Dunn (X) If a binary planet system passed close enough to Earth, it could break up the binary pair capturing one.

A new study charts 2 billion years of life's diversity and major extinctions. It highlights one of the great mysteries of Earth history: Why was life largely stagnant for a "boring billion" years, and how did it break out of that rut? 🧪 astrobiology.com/2024/12/exte...

Two unusual things happened on Earth around 460 million years ago: a bunch of asteroid impacts near the equator & an intense global cold spell. Possibly both were the result of an asteroid that broke up & gave our planet a pretty but deadly set of rings. 🧪 eos.org/articles/a-c...

Note I called this motion "retrograde" because the movement of Saturn in its orbit would actually be "to the left" in this view. But viewed from the faster moving Earth we are "overtaking" Saturn and it appears to move "to the right".
