Prompt 293

Jason takes a deep breath. He takes a deep breath, in for ten seconds, out for eight, and just takes a minute before looking again. Nope, there’s still the strange quartet of orbs in the box of what should be stolen weapons (What, the government had enough, honestly) that gave his workers the heebie-jeebies. 

Which is not the vibe he gets from them. In fact, he’s actually kind of concerned with how much he has to beat the Pit back with how quickly it lurches to latch onto the… Well they’re not gems, and he’s a little wary about touching them at first, but the Pit does seem to settle when he does.

Alright, he can deal with this. It’s not like he has several heads in a duffel bag that needs to be delivered or a tiny assassin child back in his safehouse (Seriously Talia, why was he the preferred babysitter?) or an entire gang in Crime Alley to deal with. It’ll be fine. 

…

He would like to curse out his past self, because there’s now four babies in his safehouse that appeared to have fucking hatched from the orbs. Goddamnit.

Webb reveals intricate layers of interstellar dust and gas

(These shimmering cosmic curtains show interstellar gas and dust that has been heated by the flashbulb explosion of a long-ago supernova. The gas then glows infrared light in what is known as a thermal light echo. As the supernova illumination travels through space at the speed of light, the echo appears to expand. NASA’s James Webb Space Telescope observed this light echo in the vicinity of the supernova remnant Cassiopeia A three separate times, in essence creating a 3D scan of the interstellar material. Note that the field of view in the top row is rotated slightly clockwise relative to the middle and bottom rows, due to the roll angle of the Webb telescope when the observations were taken.

"We were pretty shocked to see this level of detail," said Jacob Jencson of Caltech/IPAC in Pasadena, principal investigator of the science program.

"We see layers like an onion," added Josh Peek of the Space Telescope Science Institute in Baltimore, a member of the science team. "We think every dense, dusty region that we see, and most of the ones we don't see, look like this on the inside. We just have never been able to look inside them before."

wish i knew what to do with this helpless frustration i feel every time i see people vilify the jedi for their way of life when the person doing the vilification doesn't even understand them properly. it's one thing to criticize and dislike them if you have an accurate picture of who they were and what they're trying to do vs. hating them because you straight up don't understand them at all 😭

The 9th Heavy Fire Support, led by Sergeant Torino

Finally caved and bought some plasmaceptors, about three years too late for the meta. These guys proved oddly troublesome. All the extra tubes and details of the jetpacks really stretched out the time it took to finish up this unit. Getting that plasma glow juuuust right is still an ongoing process.

"New research suggests that these ultra-high energy rays derive their energy from magnetic turbulence."

"Ultra-high energy cosmic rays, which emerge in extreme astrophysical environments—like the roiling environments near black holes and neutron stars—have far more energy than the energetic particles that emerge from our sun. In fact, the particles that make up these streams of energy have around 10 million times the energy of particles accelerated in the most extreme particle environment on earth, the human-made Large Hadron Collider.

Where does all that energy come from? For many years, scientists believed it came from shocks that occur in extreme astrophysical environments—when, for example, a star explodes before forming a black hole, causing a huge explosion that kicks up particles.

That theory was plausible, but, according to new research published this week in The Astrophysical Journal Letters, the observations are better explained by a different mechanism. The source of the cosmic rays’ energy, the researchers found, is more likely magnetic turbulence. The paper’s authors found that magnetic fields in these environments tangle and turn, rapidly accelerating particles and sharply increasing their energy up to an abrupt cutoff.

“These findings help solve enduring questions that are of great interest to both astrophysicists and particle physicists about how these cosmic rays get their energy,” said Luca Comisso, associate research scientist in the Columbia Astrophysics Lab, and one of the paper’s authors.

The paper complements recent research published by Comisso and collaborators on the sun’s energetic particles, which they also found emerge from magnetic fields in the sun’s corona. In that paper, Comisso and his colleagues discovered ways to better predict where those energetic particles would emerge."

High sensitivity radio observations have discovered a cloud of magnetized plasma in the Hydra galaxy cluster. The odd location and shape of this plasma defy all conventional explanations. Dubbed the Flying Fox based on its silhouette, this plasma will remain a mystery until additional observations can provide more insight. A team led by Kohei Kurahara at the National Astronomical Observatory of Japan analyzed observations from the Giant Metrewave Radio Telescope (GMRT) targeting the Hydra galaxy cluster, located more than 100 million light years away in the direction of the constellation Hydra.
