@marijevh @AstroKatie How cool!
Katie Mack
📚🔭 I'm about to be on Science Friday talking about the end of the Universe! The interview (which was recorded in 2020) airs in about 10 minutes, around 3:40pm Eastern. And my book is the SciFri Book Club pick for April! More info / listen here: https://www.sciencefriday.com/sf-books/the-end-of-everything/
You can read more about the image above here https://chandra.harvard.edu/photo/2023/cena/ and browse the Chandra photo gallery to see some of the other incredible images and science the Chandra Observatory has brought us. #SaveChandra
Chandra, the space-based observatory that brings us incredible x-ray images of the most extreme environments in the cosmos, is at risk of cancellation. It’ll be a huge loss to astronomy if the mission ends prematurely for budget reasons. Go to https://www.savechandra.org/ to find out how to help #SaveChandra

Hey there Wandering.shop regulars … @AstroKatie over on her Bsky account has a “can anyone find me the title/author of this story… “ question and allowed me to share her request over here.

Does this ring a bell for any of you hardcore SF&F writers/readers?
Katie Mack boosted:
“I want to make it mean something to you. That you are in the cosmos. That you are of the cosmos.”
@AstroKatie has written (and spoken) how I experience the universe, how I want everyone to experience the universe.
…five years ago, so I’m late to the party. But thank you, Katie. It’s timeless.

@nickkohrn Thank you!! 😊
@aeva Good question! Main way is to use patterns of known absorption or emission lines. They’ll get shifted to longer wavelengths but will appear at the same places relative to each other in the spectrum
@nick_appleyard Nah nothing like that. At worst, it would require altering the expansion rate in the early universe somehow
@deepskies@astrodon.social @badastro Thank you!
@jaztrophysicist Thanks! And yeah, baryons are a hot mess 😂
Have you heard about JWST seeing galaxies that shouldn’t exist? There’s more to that story!

The September edition of my newsletter, WATCH THIS SPACETIME, is out now! 🎉
Featuring: Aliens! Quantum superposition! Airplane physics! And more!
If you’ve ever said,
“I’d like someone to explain quantum superposition to me, but in an airplane, between ATC calls and clearances,”
have I got a video for you!
Curious about quantum tunneling? Check out the latest episode of #Quantum101, from me and the Perimeter Institute for Theoretical Physics: https://youtu.be/Yg0LT3n4mYY?si=qru2ItWY14ta8giC

Loved the expression "to boldly assert" by @AstroKatie in:

Katie Mack boosted:
Healthcare workers don’t decide whether to wear gloves or sterilize equipment based on how many people are hospitalized. They just do it because it protects patients, and every patient has the right to get healthcare without becoming more sick. It should be the same with masks.
Katie Mack boosted:
The Big Bang theory tells the story of the beginning of the Universe, our cosmic home for the last 13.8 billion years. But how does the story end?
@AstroKatie shares what modern astrophysics tells us about the ultimate fate of the cosmos, and what the catastrophic destruction of all reality would look like to anyone still around to see it.
