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:

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.

Venus has lava tubes! That's so cool!

Or hot. Venus is a sucky place to live, but is super amazing for science.

Hey, if you want your mind absolutely crushed into dust today then read my article at Scientific American about how much energy is released when two supermassive black holes collide. To borrow from Douglas Adams, it's the best bang since the big one.

A newly discovered comet might — MIGHT — get bright enough to put on an interesting show. Also, astronomers may have found evidence of the very first stars!

Near the top of the FAQs I get from curious readers:

How can galaxies collide if the Universe is expanding?

The short answer is: gravity. The longer answer is fun to read, IIDSSM.

There's only one planet in our solar system Hubble has never observed. But there's another that *technically* it shouldn't, but has. Multiple times!
