Science Twitter has been all kinds of fascinating these past few days! Just a few things I’ve learned:

There’s a robot spacecraft known as Juno that’s been orbiting Jupiter for a little more than a year. It dives in for an up-close look-see to do it’s sciencey thing, then spins waaayyy far away to get out of Jupiter’s intense radiation and send back data. I’ve been following it’s flight and updates from Jupiter for a while, but this week it sent back mind-numbingly gorgeous photos of the gas giant that make me want to buy a computer monitor eight feet across so I can stare at them up close forever. Also, I’m tickled to learn that Jupiter’s Great Red Spot translates to “der Grossen Roten Fleck” in German.

Bella Boulderstone has spent her whole life studying not only has one of the coolest last names I’ve heard in a while, she’s been tweeting about galactic nuclei on Twitter under the handle @astrotweeps, which a different scientist uses each week to highlight their particular area of specialty. Boulderstone’s specialty is studying active galactic nuclei; those are the black holes at the centers of some galaxies (about ten percent, not a paltry number because there are 100,000,000,000 galaxies in the universe) that are gobbling up everything around them and spitting it out again as radiation. Our galaxy doesn’t have an AGN; it’s too old so it’s already gobbled up everything it can get its hands on, but in about four billion years, when the galaxy Andromeda crashes into the Milky way, I’m told there’ll probably be some fireworks.

Light will echo just like sound will. Sound will bounce off a far object and come to your ears after you heard the sound the first time. Light has been seen to do the same thing when it bounces off the gas around an exploding star, then come to the observing telescope after it saw the star explode.

Margaret Hamilton, the woman who wrote computer code that got the Apollo mission from the earth to the surface of the moon and back, not only got a Presidential Medal of Freedom for being so awesome, she also has her own Lego character! WANT!
