📚🔭 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

A ghostly-looking image of powerful jets of radiation coming from a galaxy. (This is Chandra’s view of the galaxy Centaurus A.) There are wispy blue bubbles in the upper left and lower right and a bright blue jet of radiation emanating from the center of the image up to the upper left.

@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

Have you heard about JWST seeing galaxies that shouldn’t exist? There’s more to that story!

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!
