Will we ever unite physics? Clocks in superposition could offer clues
Posting again for #Astrodon: Excellent, interesting study of white dwarf pollution by planets used to infer planet composition, suggesting rapid planet formation alongside star formation.
Press release here: tinyurl.com/pollutingplanets
Paper here: https://www.nature.com/articles/s41550-022-01815-8
Observational evidence from planetary systems around white dwarfs shows that planetesimal formation occurs during the first few hundred thousand years after cloud collapse. Iron accreted by these white dwarfs must have been formed by short-lived radioactive nuclides driving iron core formation in planetesimals that form together with the parent star.
this is the time of year to spot the Hyades, named for weeping nymphs from Greek mythology because its appearance in the night sky marked the start of the rainy season https://www.newscientist.com/article/mg25634110-800-how-to-spot-the-hyades-the-closest-star-cluster-to-earth
the latest feature I've edited is about JWST and how its going to be looking into exoplanet atmospheres https://www.newscientist.com/article/mg25634121-000-how-jwst-could-find-signs-of-alien-life-in-exoplanet-atmospheres/
Night on a Spooky Planet

I saw SO MANY satellites this morning. They are so bright :(
And I realize part of the problem is that the only time I'm stargazing right now is before dawn and early evening, while doing farm chores. I know from *my own simulations* that these are the worst times of day for satellite pollution. But it still really hurts to see my published predictions play out. I've never wanted to be wrong more in my life!
