Wow, a stunning image by JWST of an Einstein ring, a more distant galaxy's light being bent by gravitational lensing around a much closer galaxy. The closer galaxy is an elliptical and the much more distant galaxy, which in this case is perfectly aligned behind the foreground elliptical thereby forming the ring, is a spiral galaxy. I think this beautiful image is going to be my desktop for awhile. Just stunning!

Dark #energy is probably doing something weird, and we don’t know why.

Astronomers just announced they’re seeing more evidence that dark energy — the mysterious substance that pervades the #cosmos and causes the expansion of the #universe to accelerate — is not a constant over time, but may instead be weakening.

It means dark energy has changed over time, getting weaker and changes how we think the universe behaves in a fundamental way.

In the next few months, from its perch atop a mountain in Chile, the Vera C. Rubin Observatory will begin surveying the #cosmos with the largest camera ever built.

Every three nights, it will produce a map of the entire southern sky filled with #stars, #galaxies, #asteroids and @supernovae — and swarms of bright #satellites ruining some of the view.

Swarms of satellites are harming #astronomy.

Here’s how researchers are fighting back.
