    Today's Bad Astronomy Newsletter covers a bunch of news from NASA's DART mission, which whacked an asteroid back in 2022. Very cool stuff including streaks on the asteroid moon's surface, the plume generated, and how the orbit of the binary pair changed!

    Elon Musk has already started plans to launch a million satellites.

    Yes. A MILLION.

    This is a colossally bad idea, and it's not too late to make your voice heard. I explain everything:

    Need a place to go to get away from <all this>? Paid subbies to my newsletter get a big ol' dose of the cosmos 3 times a week! Like today's issue about lightning on Mars, China may have already peaked its CO2 emission, and finding meteors seismically.

    We've discovered over 6,000 alien worlds. But do these exoplanets have exomoons and exorings? Almost certainly! And we're allllllllmost there in discovering them, too.

    A solar eclipse seen… FROM SPACE?!

    Yup. And it's an annular one, too, making it extra cool.

    And oh yeah by the way a small galaxy may be ramming through the Milky Way too so I wrote about that because why not.

    A pulsar is one of the scariest objects in the universe, yet we keep finding planets orbiting them. Of course, any pulsar planet is gonna be weird… but still, here's an egg-shaped one that may once have been a star and got mostly eaten. So, yeah.

    In other news…

    This was fun: a reader asked if aliens were in a galaxy 66 million light-years away, how big a telescope would they need to see dinosaurs on Earth?

    Guess!

    No; bigger. Try again. Nope, still bigger. Third try? Nope. Way, WAY bigger.
