A 'ring of fire' eclipse will be visible in the sky this week

Plus, we're talking UFOs again, NASA's Venus missions, the near-extinction of sharks 19 million years ago and much more!

SpaceX launches squid and tardigrades to the International Space Station Hello, humans! I put the call out for questions and you guys really responded with feedback. Awesome. Thanks a ton! Now onto this week's #content, which this letter is #full of: June 10 sees another celestial feast for the (protected) eyes in the form of a ring of fire eclipse. Parts of the US will be able to experience the eclipse in full, so get reading below. We also see the return of UFOs this week, as we inch closer to the US government's unclassified report. A few of you wrote in about your experiences with unidentified objects -- some bizarre encounters out there and some of you are certain you've seen alien spacecraft! I'm sure you'll be interested in reading the report. On top of that, we have the tiny squids journeying to space at the link above, the near-extinction of all sharks 19 million years ago and NASA's plans to return to Venus after three decades with two new missions. But before you read about all that, let's get into The Mailbag. 📧The Mailbag📧 Candy asks: Science teaches us that nothing can escape from a black hole. Yet every picture shows streams of something jetting out from the black hole. What is it and how does it escape from the black hole? Excellent question Candy. There's a couple of points to make here. First, we've only ever "seen" one black hole and so every other picture is an illustration. But astronomers have a lot of data and imagine showing some truly extreme physics happening ~around~ a black hole, including huge jets stretching light-years into space. Those jets aren't actually shooting out from the black hole, they're particles and gas and dust and debris orbiting very, very close to the event horizon -- the point of no return. Some of these particles get spun up and shot out of the region just around a black hole's event horizon because of, scientists believe, powerful magnetic fields. So it doesn't escape from inside the black hole, but from the gravity just outside of it. Astronomers continue to study these jets to learn about the ways matter interacts with a black hole. Wild stuff. Candy also sent a recommendation for me: Move my ask for questions a little lower. So, here it is: If you have any burning questions, send me an email or a message on Twitter and check next week for an answer. Have a great week! Enim scientia et astra!
