@decryption 🤦🏻

Incredible new #JWST deep field (120 hours!) released by folks from ESA/NASA Webb teams.

Not only is nearly everything in this image a galaxy (the two spiky stars are not), but those curved arcs are images of galaxies beyond this cluster, which are projected and warped into our view thanks to the power of gravity!

It's called a gravitational lens. To visualise what's happening, take a look at this diagram.

There are distant galaxies that we can't normally see. There's also a galaxies between them and us, with lots of mass.

This mass warps space-time and bends the distant galaxy light towards us so we see them.

I am amazed. You should be amazed. This is a really epic image.

@decryption is that Ghiblified AI art on the poster?
@Dangerous_beans any day that includes dumping a load of yucca is a good day - that shit is hard to get rid of
@PetraSchwer An experience I remember clearly from studying quantum physics as an undergraduate was being able to relate the mathematics to a physical phenomenon - even if it wasn't something that I could observe directly. Understanding those relationships really helped the mathematics slot into place, and vice versa.
@evcricket fucking hell
@elzbethmrgn pretty sure I know what exercise smells like - not sure I would sell it, tho
@decryption I use an Aeropress and a Clever filter and they both make absolutely delicious coffee. I use a Kingrinder K6 hand grinder, which does an excellent job. You don't need anything fancy or expensive.
@elzbethmrgn we voted after 3pm so everyone had packed up - my kids were highly miffed but there was exactly 0 line to vote, so 🤷🏻
@elzbethmrgn that and the bake sale
