The best thing today was that we all lifted our gaze from ourselves to the universe for a moment.

JWST image 

So, what are we looking at in this image?

nasa.gov/sites/default/files/t

The image is stunning, a huge leap over Hubble (comparison at imgsli.com/MTE2Mjc3 ) and really showcases JWST.

The main target is a cluster of galaxies called SMACS 0723 (or more completely J0723.3-7327). Here's a preprint about the cluster: arxiv.org/abs/2207.05007

0723 is very far away, NASA says 4.6 billion light years. Astronomers measure these big distances as redshift, z. Our galaxy is z=0, 0743 is at z=1.38 to z=1.45

I think all of the spiky bois in the image are foreground stars (in our galaxy), so just a few hundred thousand light years at most.

The really interesting bit, and the reason for imaging 0723, is the stuff that's even farther away -- the gravitationally lensed galaxies, with their light smeared into crescents and whorls as it travels past 0723 towards us. We could see some of this with Hubble, but the added sensitivity with JWST is just spectacular. Those galaxies will be at z=6 and even deeper.

@peterdrake how the heck did you realize you could make a card game out of fire knife dancing?

math makes so much more sense when you actually have something to use it on

NASA has announced the images and data that will be shown at the JWST press conference next week! If you haven't already, now is the time to mark your calendars for Tuesday July 12th at 10:30 am Eastern! 🗓️

This is the first real *science quality* data that the public will see!!

On the exoplanet side, we recently heard rumors that they planned to show an exoplanet spectrum at this event - and now we know what target! I'll put some info about WASP-96b in a thread below ⬇️

I've been working my way through love death and robots. the drowned giant was my least favorite so far. disliked the narrator pretty much immediately and found the whole story boring, pointless, hifalutin bullshit

i like most of it though. i really enjoyed the season 2 opener, having listened to the short story by Scalzi that it's based on a couple times before. All Through the House has a hilarious twist 😆

if you've seen it, do you have a favorite?

I'm somewhat ashamed to admit that I didn't follow my own advice here, but it may help someone else make a better choice.

Don't sign a retention agreement that requires you to pay back money to the company should you choose to leave early. Unless you're a psychopath probably (or an economist), that's going to set up some costs in your biased human mind that are way imbalanced between you and the company. at the very least, if you go for this, negotiate better terms than I did--I agreed to two years for what amounts to barely more than two months salary *if* I stick it out, besides the opportunity cost for what I could be making elsewhere.

If I do switch before the term is up, there's the slightly uncomfortable option of negotiating with my next employer to make up the difference in paying back my current employer. It seems pretty doable if I go to a similarly sized company, but it's a hassle for not all that much money relatively.

Indie Bundle for Abortion Funds is NOW LIVE

100% of the proceeds from this bundle will go to the National Network for Abortion Fund's Collective Power Fund, which moves money directly to abortion funds across 20+ U.S. states, with a particular focus on the South and Midwest.

The Indie Bundle for Abortion Funds includes almost 800 works by over 600 developers, writers, artists, and creators, and you can pick it up until July 13th here;

#German animal names are really something.

sloth: Faultier (“lazy animal”)
seal: Seehund (“sea dog”)
turtle: Schildkröte (“shield toad”)
skunk: Stinktier (“stink animal”)
squid: Tintenfisch (“ink fish”)
slug: Nacktschnecke (“nude snail”)
hippo: Nilpferd (“nile horse”)
armadillo: Gürteltier (“belt animal”)

Murmeltier, (marmot, “mumble animal”) has nothing to do with mumbling, by the way. It’s from “murmenti”, based on Latin “mus montis”, “mouse of the mountain”.

#etymology

are there experiments you can only perform once ever? if so, how would you plan for and conduct them?

i got real blackout drapes and i can't see anything in my room and it's the best

Results from the sample returned from asteroid #Ryugu by the #Hayabusa2 probe. As expected, they found amino acids.

"[T]he results show that the asteroid Ryugu is the most primitive, unaltered object ever studied, much the same as it was when the solar system itself was new."

BTW you may have seen this GIF labeled as "shark bites fiber optic cable" and wondered if it was correct.
Sharks have that electroreception sense that lets them sense the electric field of fish, but fiber optic cables are just light. Why would they attack fiber optics?
