NASA Hubble Team Finds Monster ‘El Gordo’ Galaxy

NASA’s Hubble Space Telescope has weighed the largest known galaxy cluster in the distant universe, catalogued as ACT-CL J0102-4915, and found it definitely lives up to its nickname — El Gordo (Spanish for “the fat one”).

By measuring how much the cluster’s gravity warps images of galaxies in the distant background, a team of astronomers has calculated the cluster’s mass to be as much as 3 million billion times the mass of our sun. Hubble data show the galaxy cluster, which is 9.7 billion light-years away from Earth, is roughly 43 percent more massive than earlier estimates.

The team used Hubble to measure how strongly the mass of the cluster warped space. Hubble’s high resolution allowed measurements of so-called “weak lensing,” where the cluster’s immense gravity subtly distorts space like a funhouse mirror and warps images of background galaxies. The greater the warping, the more mass is locked up in the cluster.

Seven billion light-years from Earth, two galaxy subclusters are colliding at a speed of several million kilometers per hour. While it is officially known as ACT-CL J0102-4915, the results of this collision are nicknamed ‘El Gordo,’ which is Spanish for “The fat one” or “The big one.”

El Gordo has earned its moniker. At 2 quadrillion times the mass of our Sun, the cluster is the largest known in the Universe. El Gordo was discovered by scientists at the Chandra X-Ray Observatory, and is a place of many extremes. According to researchers, this cluster is also the hottest and gives off the most X-rays of all the known clusters in the distant Universe.

Stars make up only about 1% of the cluster’s mass, with the rest composed of hot gas that can reach searing temperatures of 200 million degrees Celsius. The galaxy at its center emits extremely bright bluish light and is believed to be the aftermath of a galactic merger. 

Researchers hope that studying El Gordo will unravel some mysteries about dark matter and energy. As El Gordo’s subclusters merge, the force of the collision slows down the gas but not the dark matter, wrenching them apart. This, as well as several other characteristics, leads researchers to believe that El Gordo formed in a manner similar to the Bullet Cluster (click here for info on the Bullet cluster).

Despite its extreme characteristics, El Gordo fits within current models of the Big Bang, though it is at the upper limit of what our cosmology can explain.

I do suffer love indeed, for I love thee against my will.

Anon asked: Could you please write some beadick au before the hero/claudio drama, team love gods doesnt get them together, instead ben lands in the hospital and bea freaks out & doesnt know why shes freaking out & visits him constantly & maybe fluff??

A/N: I went a little off prompt here, he’s not in the hospital for long but I hope you like it! /// 4915 words [ao3 link]

Bea opens the door and rushes into the room. “Oh, my god, are you okay?” 

She first registers Pedro sitting on one of the chairs. Balthazar is standing in the corner, Hero is sitting closet to the hospital bed (with Claudio hovering behind her) and Benedick is lying in the hospital bed.

“Peachy,” Ben says. He- the bastard- is eating a pudding cup and grinning at her.

“What the hell?” Bea demands of the room in general. “I get a text saying that Benedick is ill and is in the hospital and no one bothers to text me that he’s okay?”

“You said my name without emphasizing my dick,” Ben says with another stupid smile.

“He’s slightly high right now,” Pedro says. “And he’s having surgery tomorrow morning.”

“For what?” Bea walks to the end of his bed and picks up the chart there. 

“Appendicitis,” Hero answers.

“You can’t actually understand anything on that chart,” Pedro says, laughing at her.

“Yes I can!” Beatrice snaps. “Look, right here, Ben’s allergic to hazelnuts.”

“They make my mouth feel like it’s made of tingly moss,” Ben puts in helpfully. 

Beatrice turns her stare on him. “If you weren’t already in the hospital I would beat you up for making me think that you were dying.”

She storms out of the room, ignoring Pedro laughing at her.

She starts to walk out of the hospital, but it seems wrong, to just leave like that when Ben is upstairs waiting for surgery. She lingers of a second, and then tells herself that she’s being ridiculous, and leaves.

Derek knew the moment he opened the front door of his clean and pristine apartment to Stiles Stilinski holding a small boy, a cluster of bags, and a suitcase, he was screwed. In every way possible. Undone by the big brown eyes of a small child and his annoying, witty, and attractive father.
