The Year’s Most Spectacular Photos from the James Webb Telescope
By Jeffrey Kluger
December 22, 2023
Tumblr media
Close to 1,500 light years from Earth lie a pair of baby stellar twins known as Herbig-Haro 46/47 — which are barely a few thousand years old.
A star the size of our sun, by contrast, takes an average of 50 million years to reach even the stellar equivalent of young adulthood It's Herbig-Haro 46/47's extreme youth that gives the formation more of a blob-like appearance than the stellar duo it is.
Young stars are buried in clouds of dust and gas, which they absorb as they grow. Sometimes, however the infant stars ingest too much material too fast.
When that happens, dust and gas erupts from both sides of the formation, giving the young pair their misshapen look.
But if you have patience — 50 million years worth of patience — what is a blob today will be stars tomorrow.

A pair of brilliant stellar nurseries located 1,600 light years from Earth, the Orion Nebula and Trapezium Cluster are home to a relative handful of very young but very bright stars.
Four of the stars are easy to see with a simple, amateur, four-inch telescope.
One of the four — the beast of the young litter — is especially visible, a full 20,000 times brighter than our sun.
Apart from their four main stars, the Orion Nebula and Trapezium cluster contain approximately 700 additional young stars at various stages of gestation.

(L): It’s not easy being a Wolf-Rayet star, like this specimen imaged by the Webb telescope at a distance of 15,000 light years.
A rare species of stellar beast — NASA estimates there are only 220 of them in a Milky Way galaxy with at least 100 billion stars — the Wolf-Rayet burns hot and burns fast, with temperatures 20 to 40 times the surface of the sun.
All of that rapidly expended energy causes the star to lose its hydrogen envelope quickly and expose its helium core.
The result: a very early and very violent death.
A star like our sun burns for about 10 billion years. As for a Wolf-Rayet? Just a few hundred thousand before it dissolves into cosmic dust.

(R): If the Wolf-Rayet star dies an ugly and violent death, the celebrated Ring Nebula, photographed by the Webb at a distance of 2,000 light years from Earth, has been expiring beautifully.
The glowing remains of a sun-like star, the nebula was discovered in 1779 by the French astronomer Antoine Darquier de Pellepoix.
As the nebula throws off its outer layers of ionized gas, it reveals its characteristic blue interior, composed of hydrogen and oxygen that have not yet been expelled off by the nebula’s stellar wind.

Dwarf galaxy NGC 6822 lives up to to its name — home to just 10 million stars, compared to the minimum of 100 billion in the Milky Way.
But what NGC 6822 lacks in numbers, it makes up in spectacle — which the keen eye of the Webb telescope has revealed.
Discovered in 1884 by American astronomer E.E Barnard, NGC 6822, is now known to have a prodigious dust tail measuring 200 light years across..
What's more, it's home to a dense flock of stars that glow 100,000 times brighter than our sun.

Spiral galaxies are often defined by uneven — and even ragged — arms.
But not galaxy M51, which lies 27 million light years from Earth and is defined by the tautness of its arms and the compactness of its structure.
M51 isn't alone in space. Nearby lies the companion galaxy NGC 5195.
The two galaxies are engaged in something of a gravitational tug of war — one that the NGC 5195 is winning.
NGC's constant gravitational pull is thought to account for both the tightly woven structure of M51's arms and for tidal forces that are thought lead to the creation of new stars in the arms.

Just below Orion’s belt lies one of the most celebrated objects in the night sky: the Orion Nebula, a stellar nursery that is home to about 700 young stars.
This Webb image focuses not on the entirety of the nebula but on a structure in the lower left-hand quadrant known as the Orion Bar.
So named because of its diagonal, ridge-like appearance, the bar is shaped by the powerful radiation of the hot, young stars surrounding it.

A baby by stellar standards, the IC 348 Star cluster is just five million years old and located about 1,000 light years from Earth.
Composed of an estimated 700 stars, IC 348 has a structure similar to wispy curtains, created by dust that reflects the light of the stars.
The conspicuous loop in the right hand side of the image is likely created by the gusting of solar winds blowing in the direction that, from Earth, would be west to east.

When it comes to galaxies, there's big and then there's huge and by any measure, Pandora's Cluster — more formally, known as Abell 2744 — qualifies as the latter.
Not just a galaxy, and not even a cluster of galaxies, Abell 2744 is a cluster of four clusters, which long ago collided with one another.
Located 3.5 billion light years from Earth, Pandora's Cluster measures a staggering 350 million years across.
The cluster's massive collective gravity allows astronomers to use it as a gravitational lens, bending and magnifying the light of foreground objects, making them easier to study.

Webb was built principally to look at the oldest and most distant objects in the universe, some of 13.4 billion light years away.
But doesn't prevent the telescope from peering into its own back yard.
This image of Saturn and some of its 146 moons, rivals the images obtained by the Pioneer and Voyager probes.

Infant stars are born all over the universe, but the closest stellar birthing suite to Earth is the Rho Ophiuchi cloud complex, located just 460 light years distant.
A turbulent — even violent — place, Rho Ophiuchi is defined by jets of gas roaring from young stars.
Most of the stars in this comparatively modest nursery are more or less the size of the sun.
But one, known as S1, is far bigger — so much so that it is self-immolating, carving a great cavity around itself with its stellar wind, the storm of charged particle's all stars emit, though few with the gale-force power of S1.

I ask this as a Clerith fan myself - why are so many people up in arms about Tifa "lying" in her GS date? I'm not even sure what people are referring to when they say that. If it's when she denied talking to Aerith about Zack... Aerith literally lied about the EXACT same thing to Cloud and no one calls her out about it.
Obviously the context of Cloud bringing up the issue in the first place is quite different with both girls - with Aerith he's wanting to know where they stand and if he can pursue her or if he should give up. While with Tifa he's still focused on Aerith instead of the girl he's with, which makes this date and his extreme (frankly OOC) actions come across as a rebound because he feels like he has no chance with the girl he's really interested in. But that said, I interpret the lie itself as the same from both girls - they know Cloud's memory is unreliable and digging too much into the topic of Zack might make him MORE unstable, so they dodge the issue. Also maybe a secondary reason of lying to keep the mood light/romantic, instead of bogging it down with something heavy.
If it's in response to what she says after Cloud wonders about Aerith still having feelings for Zack... that's up to interpretation, I guess. PERSONALLY, I would take her responding "It's more complicated than that" as dodging the question at worst or even a soft, implied disagreement with Cloud at best. It would be incredibly easy and simple to just say, "Yes, she still likes him." That's NOT what Tifa says, even though to an extent it might be true (Aerith makes it obvious that she's fallen for Cloud by the end of the game, but she MIGHT still love Zack too. You can love more than one person at a time. It's just unclear if that's the case for her or not).
We know from the scene on the ship heading towards Costa del Sol that Tifa and Aerith wanted to talk about love and boys, but it was postponed. But it's also clear they're spending a LOT of time together trying to hash out what's going on with Cloud and generally opening up to each other as friends off-screen, so I think it's safe to say they DID have this conversation eventually. I believe by the chapter 12 date, both girls are fully aware that they EACH like Cloud romantically, but for the most part they care enough about each other as friends to put aside rivalry/jealousy.
Tifa's response of "It's more complicated than that" just feels like the honest truth to me. Does Aerith still have feelings for Zack? Yeah, maybe. But she also undeniably has feelings for Cloud. And Tifa, on a date with the man she ALSO loves, doesn't want to lie but also can't bring herself to say that whole truth (also it's not really her truth to say? Confessing for someone else is messed up in its own right NGL) when doing so would almost certainly kill her own chances with Cloud.
I honestly feel sorry for her in her date. I read the situation as her trying to be as honest as she can without quite literally triggering Cloud or spilling Aerith's secrets, while Cloud, AT BEST is acting out a role with her and being the suave hero who he thinks she wants (which is arguably true, but let's not get into whether Tifa wants the "real" Cloud here) instead of his true awkward self (thus no actual progress in their relationship is made, since everything was just an act on his part). And AT WORST is outright using her as a rebound.
Seriously, what are you all mad at HER for?

Been reading the Sadeian woman after @normalbrothers mentioned it in relation to Diana Mitford, many thoughts but tumblr (and no computer on holidays) is. Poor format for those thoughts
That said, in a(n unrelated?) tangent, the books framing of the written pornographer’s role in reinforcing sexual dynamics/norms (and that this is why de Sade was at least worthy of analysis because he challenged sexual/gender/power dynamic norms) makes me wonder regarding the propensity (call it the dominance; the dominant minority) of readerfic these days (writ by women for women and using the 'self insert' motif to tackle first person POV) and how it’s recolonised fannish spaces back to a particular model of acceptable pornography through sheer flooding quantity .
“our Chr1s+ian (?) moral duty to reclaim queer pornography to reassert normative sexual dynamics between a man and a woman, or a man and a man, or a woman and a woman*” and clean up all that dirty sexual power gender role dynamic complexity etc etc etc there’s only a very limited range of acceptable incest to fetishise etc etc mumble mumble even gay readerfic back to hole and prod mumble mutter mumble

Mav learns ASL because he wants to be able to talk with Ice even when there isn't any kind of electronic device in the vicinity. The first world he signs I love you and thank you, they are at a stupid gala for a stupid Navy event and all Ice can do is squiz his knee and ignore all the tears he would like to cry.
(Tom and how he learned ASL)

Me being very rational and normal about my blorbos: in the Zack timeline in Rebirth, Biggs brings Zack to take a look at an Avalanche poster asking people to meet up and fight Shinra. Right next to the poster is a Banora White poster. As Biggs and Zack go to the meeting point, they have a conversation where a) Biggs talks about how he's struggling to find his "role" in this timeline and b) they both mention having memory issues. Furthermore, it's suggested someone has actively worked to make Biggs survive, and also to make Zack survive - but are these the same person? Was this Cloud's seven seconds? But why would he save Biggs alone, not Jessie too, and why would he save Zack when he didn't remember him? The only other person we know of who has the power to change things seems to be Sephiroth, that had no interest in either Zack or Biggs. Now later, Zack tells Biggs that when things get tough, he has to rely on, "I dunno - hopes? Dreams maybe? Something like that", which seems to be a reference to Angeal's lessons regarding dreams and honor. However, it is strange Zack would struggle to remember that, given how important Angeal was to him.
Therefore, considering the discussion of roles to play and the reoccurring Banora White imagery, is it possible that Genesis is playing some role that we still haven't seen? Could someone - perhaps Sephiroth - have done something to attempt to change some of the events of Crisis Core, thus causing Zack to misremember them? Could Genesis also have some power to change things, and have been the one to save Zack rather than Cloud, whether to fight Sephiroth or for his own gains? Or is the fact that Biggs survived, while Jessie - who we see played Loveless as part of her career - presumably died something to be read into?

here's the thing.
in one piece's skypieia arc we see the shandians praying to the sun god 400 years ago bc they are dying of the plague and want to be saved. and then in episode 192 when enel is trying to sink upper yard with his huge ball of fucking thunderclouds we see the people of skypieia praying to god to save them, and conis wondering if god is actually real, right?
and then the scene cuts to luffy doing his usual shit and saving the day and dissipating the huge ball of fucking thunderclouds before it kills everyone and destroys the ancient land of the shandians.
which hits a bit different after finding out approximately one billion episodes later that oh luffy didn't actually eat the devil fruit which turns your body into rubber, it actually was the fruit of oops you're now more or less the reincarnation of the sun god, enjoy. yeah.

Waiting for Tallulah to meet ElQuackity and just immediately clock onto the fact that that man is Not the other part of her OTP with her dad, he is an imposter and she will not be comfortable around him (probably scared out of her mind, as long as she’s not blinded by her bias but she can be quite shrewd when necessary so I have faith in her noticing that not all is right with the man who clearly cares for her despite being a petty, inconsiderate arse most of the time).
