The Greyjoys Aren’t Even Weird That’s Just What Having A Lot Of Uncles Does To You. They Keep Disappearing

just found out I’m reincarnating as one of those immortal jellyfish in my next life. this is so fucked man i’m never going to escape samsara

My friends who just got their first glasses: i need this highly expensive special cloth to wipe them, I also have this eyeglass cleaner from the same company, did you know you shouldn't use your t shirt unless it's specifically soft

Me who's worn glasses since middle school: *slaps soap onto the glasses and washes them in the sink then wipes them with toilet paper* what

jon snow at politics: Sam my close personal friend Sam who would die for me just rigged the nights watch lord commander election for me because he is charismatic and good at talking to various different oppositional factions of the watch to get them to support me which is the only reason I have the power I do. What should I do with an ally that has that skillset? Exile him to wizard school against his will on the other end of the continent by himself for multiple years🙂‍↕️🙂‍↕️🙂‍↕️I should only allow my enemies who want to kill me near me☝️

jon snow at municipal loan negotiation for some goddamn reason:

I feel like typically the "dead wife" montage does nothing for me, even when executed very well, because it's often just like "here's this woman you'll never get to meet, she only matters because a man loves her so much and now he's sad."

But the montage wasn't just Mark's recollections. It was her perspective too. He's her dead husband. He's her Eurydice as much as he's his own Orpheus.

This isn't humanizing Gemma for Mark's sake. This is humanizing Gemma for Gemma's sake and it's there not for us to root for Mark, it's there for us to realize we're rooting for Gemma. Every moment Mark reaches out for her, she's reaching back.

The dead wife montage normally deprives a woman her agency, making her a tool for a man's arc, but this episode fully restored Gemma's agency. She's fighting back, she's yearning too. She hurts, she aches, she angers. She fights, she bleeds, she gets frustrated too. And has been before she was ever Ms Casey,

I've never seen a show restore a character's humanity as fully as this single episode did for Gemma. She went from an abstract concept--a wife, a severed employee, a ghost--to a tangible person.

And this was realized so literally as well. We literally see her bleed, we literally watch her eat, her hands cramp up, her teeth ache. It's like watching a hologram become flesh muscle by muscle, bone by bone.

I'm in awe of what they were able to do for her in just 50 minutes. In many ways, I feel I know Gemma better than I know half the cast.

Unexpected complex chemistry in primordial galaxy

University of Arizona astronomers have learned more about a surprisingly mature galaxy that existed when the universe was just less than 300 million years old – just 2% of its current age.

Observed by NASA's James Webb Space Telescope, the galaxy – designated JADES-GS-z14-0 – is unexpectedly bright and chemically complex for an object from this primordial era, the researchers said. This provides a rare glimpse into the universe's earliest chapter.

The findings, published in the journal Nature Astronomy, build upon the researchers' previous discovery, reported in 2024, of JADES-GS-z14-0 as the most distant galaxy ever observed. While the initial discovery established the galaxy's record-breaking distance and unexpected brightness, this new research delves deeper into its chemical composition and evolutionary state.

The work was done as part of the JWST Advanced Deep Extragalactic Survey, or JADES, a major James Webb Space Telescope program designed to study distant galaxies.

This wasn't simply stumbling upon something unexpected, said Kevin Hainline, co-author of the new study and an associate research professor at the U of A Steward Observatory. The survey was deliberately designed to find distant galaxies, but this one broke the team's records in ways they didn't anticipate – it was intrinsically bright and had a complex chemical composition that was totally unexpected so early in the universe's history.

"It's not just a tiny little nugget. It's bright and fairly extended for the age of the universe when we observed it," Hainline said.

"The fact that we found this galaxy in a tiny region of the sky means that there should be more of these out there," said lead study author Jakob Helton, a graduate researcher at Steward Observatory. "If we looked at the whole sky, which we can't do with JWST, we would eventually find more of these extreme objects."

The research team used multiple instruments on board JWST, including the Near Infrared Camera, or NIRCam, whose construction was led by U of A Regents Professor of Astronomy Marcia Rieke. Another instrument on the telescope – the Mid-Infrared Instrument, or MIRI, revealed something extraordinary: significant amounts of oxygen.

In astronomy, anything heavier than helium is considered a "metal," Helton said. Such metals require generations of stars to produce. The early universe contained only hydrogen, helium and trace amounts of lithium. But the discovery of substantial oxygen in the JADES-GS-z14-0 galaxy suggests the galaxy had been forming stars for potentially 100 million years before it was observed.

To make oxygen, the galaxy must have started out very early on, because it would have had to form a generation of stars, said George Rieke, Regents Professor of Astronomy and the study's senior author. Those stars must have evolved and exploded as supernovae to release oxygen into interstellar space, from which new stars would form and evolve.

"It's a very complicated cycle to get as much oxygen as this galaxy has. So, it is genuinely mind boggling," Rieke said.

The finding suggests that star formation began even earlier than scientists previously thought, which pushes back the timeline for when the first galaxies could have formed after the Big Bang.

The observation required approximately nine days of telescope time, including 167 hours of NIRCam imaging and 43 hours of MIRI imaging, focused on an incredibly small portion of the sky.

The U of A astronomers were lucky that this galaxy happened to sit in the perfect spot for them to observe with MIRI. If they had pointed the telescope just a fraction of a degree in any direction, they would have missed getting this crucial mid-infrared data, Helton said.

"Imagine a grain of sand at the end of your arm. You see how large it is on the sky – that's how large we looked at," Helton said.

The existence of such a developed galaxy so early in cosmic history serves as a powerful test case for theoretical models of galaxy formation.

"Our involvement here is a product of the U of A leading in infrared astronomy since the mid-'60s, when it first started. We had the first major infrared astronomy group over in the Lunar and Planetary lab, with Gerard Kuiper, Frank Low and Harold Johnson," Rieke said.

As humans gain the ability to directly observe and understand galaxies that existed during the universe's infancy, it can provide crucial insights into how the universe evolved from simple elements to the complex chemistry necessary for life as we know it.

"We're in an incredible time in astronomy history," Hainline said. "We're able to understand galaxies that are well beyond anything humans have ever found and see them in many different ways and really understand them. That's really magic."

The NIRCam data was used to determine which galaxies to study further with spectroscopic observations. One such galaxy, JADES-GS-z14-0 (shown in the pullout), was determined to be at a redshift of 14.3, making it the current record-holder for most distant known galaxy. This corresponds to a time less than 300 million years after the big bang.  NASA, ESA, CSA, STScI, Brant Robertson (UC Santa Cruz), Ben Johnson (CfA), Sandro Tacchella (Cambridge), Marcia Rieke (University of Arizona), Daniel Eisenstein (CfA), Phill Cargile (CfA)

LOWER IMAGE: Timeline of the universe: Although we are not sure exactly when the first stars began to shine, we know that they must have formed sometime after the era of Recombination, when hydrogen and helium atoms formed (380,000 years after the big bang), and before the oldest-known galaxies existed (400 million years after the big bang). The ultraviolet light emitted by the first stars broke down the neutral hydrogen gas filling the universe into hydrogen ions and free electrons, initiating the era of Reionization and the end of the Dark Ages of the universe.  NASA, ESA, CSA, STScI
