Most galaxies don't have any rings of stars and gas -- why does M94 have two? First, spiral galaxy M94 has an inner ring of newly formed stars surrounding its nucleus, giving it not only an unusual appearance but also a strong interior glow.

A leading origin hypothesis holds that an elongated knot of stars known as a bar rotates in M94 and has generated a burst of star formation in this inner ring. Observations have also revealed another ring, an outer ring, one that is more faint, different in color, not closed, and relatively complex. What caused this outer ring is currently unknown. M94, pictured here, spans about 45,000 light years in total, lies about 15 million light years away, and can be seen with a small telescope toward the constellation of the Hunting Dogs (Canes Venatici).

Physicists distorted a type of material known as a photonic crystal to divert the path of light much as it would passing through a gravitational field.

The observable universe is 93 billion light years across. That's big. Alan Guth made a calculation about inflation in the early universe that says the entire universe could be 150 sextillion times larger than that. That's 150 with 21 zeroes after it, times 93 billion.

Astronomers found that the universe is at least 250 times larger than the observable universe, or at least 7 trillion light-years across. "That's big, but actually more tightly constrained that many other models," according to MIT report.

well, I can't say I expected the new chapter to feature Idia (metaphorically) going to (metaphorical) hell, getting a pep talk from his (metaphorical) Phantom brother which helps him finally move on once and for all from his brother's death, and (metaphorically) overblotting again to fight his way back out of (metaphorical) hell, only to have his darkest fear (non-metaphorically) come true when his mom goes through his computer and finds all his secret files. but I am glad it did!

also this is all a flashback for the purpose of explaining to our group what the heck is going on (whether or not any of it is getting through is another matter)

"we need more complex female characters" you couldn't even handle her

#ash: hey idk if it’s a good idea to give full access of the most advanced warship we have to a mercenary who shot a suspect in cold blood #and a cop who quit his job because there were too many rules (and also happens to be a member of the military we were recently at war with)#also i think the council will throw us to the wolves to save themselves #like half the fandom: omg space racist???#sorry for discourse posting™ but i saw a terrible post that rocketed me back into 2013 #anyway we may have preferences but we love and appreciate both virmire survivors in this house #mass effect #ashley williams

A small comic that came about after I started theorizing about PLA’s place in the timeline. How Clay got his hat... 🤔

More under the cut about why I think these two actually knew each other

Un-augmented Julian Bashir who programs a special button on his AAC device just for talking to Garak. It makes a loud incorrect buzzer noise.

#I am once again thinking about Him (un-augmented!Julian my beloved)#Unfortunately Garak LOVES the buzzer. It's like a Pavlovian bell to him. The opposite of a deterrent.#garashir #Julian Bashir #Star Trek: Deep Space 9 #obviously the AAC devices of the 23rd century will be far more advanced than this but perhaps they still include buttons/typing as a backup #in case there's an issue with the tech that translates ur thoughts directly to words (I picture it working via a device #that looks like a modern-day hearing aid; it wirelessly syncs with UTs of course)#also the devices will surely be able to recite the words in your own voice (or any voice you choose)#but it IS funny to imagine the Majel Barrett computer voice flatly declaring ''Garak That Is The Most Ridiculous Lie I've Ever Heard''#Starky's text posts #Starky's original posts #oh uhhhh #autism

The Veil Nebula is a large supernova remnant, the expanding debris cloud from the death explosion of a massive star toward the constellation of the Swan. Veil's estimated distance is approximately 1,400 light-years from planet Earth ✨️

If the Sun was scaled down to the size of a white blood cell, the Milky Way galaxy would be the size of the continental United States 🇺🇸

Scientists believe light speed travel is possible. A functioning warp drive would allow humans to reach the far ends of the cosmos in the blink of an eye: https://rb.gy/r7aiv

Imagine a massive celestial bubble made of ice and dust surrounding our Solar System. That’s the Oort cloud and this is its scale.

The Oort Cloud lies at the very edges of the Solar system. Even the farthest ones which are still working, like Voyager 1, Voyager 2 and New Horizons didn't go beyond the cloud. Long period comets, taking centuries to orbit the Sun, provide evidence for the existence of the Oort Cloud. Scientists believe this vast region is the birthplace of these cosmic travelers...✨

"Yeah, sure, and I shit thermite. Be serious."

So. Maybe, he’d gone a little overboard after work that day. He’d admit that. Drinking the sad away wasn’t the most mature way to handle things, but when you got a letter from your dad saying-

Well saying that, you know, maybe it was okay to have a beer or two. In theory. In practice, that meant that two-beers-deep Earl had to somehow have enough willpower to say “naw, I don’t wanna become three-beers-deep Earl,” and then three-beers-deep Earl’s gotta say no to four-beers-deep Earl, and it’s just a bit of a shitshow from there.

Pardon the french.

At least he wasn’t on the clock. The worst thing that should’ve happened to him was waking up tomorrow with a fatass headache and upset friends. Instead, he was in the hospital, surrounded by men with guns, osmotically absorbing the most surreal conversation of his life.

“We’d heard that humans had remarkable healing abilities but this is incredible. Anyone else here would be dead, he’s just showing some signs of esophageal irritation.”

“We got any idea of the culprit?”

“We’re looking over security footage but the culprit must be some kind of ghost. We’ve gone over the security footage at least twenty times, nobody can spot a thing.”

Earl couldn’t help it. He spoke.

“What are you talking about?”

The detective and the doctor jumped at the sound of his voice.

“What the shit-

The doc’s hand went over the detective's mouth, cutting off the oath just a hair too late. The duo looked after each other, before the detective gestured for the doctor to go first.

“I… don’t have very much experience with humans. We thought it’d be a couple of days at least before you woke up. How are you feeling?”

Earl coughed a few times.

“Throat’s raw, head’s pounding, and would kill for anything fried in grease. Pretty standard hangover.”

The detective cut in at that.

“Eh, except for the part where someone poisoned you.”

Earl shrugged.

“Must not have been very good poison.”

The lawman didn't laugh.

“Hydrochloric acid mixed with potassium salts? You can bet your pink ass it’s a good poison. Anyone else here would be dying from a hole in their gut. You been making enemies on the station, colony-boy?”

Earl’s smart alec remark froze as his one semester of biology 101 clawed its way to the front of his brain.

“Oh.”

The detective clicked his pen, ready to start taking notes, even as Earl waved him off.

“No crime here doc, my stomach makes that stuff naturally.”

The doctor blinked even as the detective rolled his eyes.

“Yeah, and I shit thermite. Be serious pal, there’s someone here out to get you.”

Earl held his gaze, and after a few moments, the detective’s annoyed face transformed into numb confusion.

“...Hot damn, you aren’t joking. You’re telling me you can spew concentrated acid on a whim?”

The question hit a little close to him, and Earl felt his ears burn.

“Eh… not… on a whim. More like, after six or seven beers.”

The doctor grabbed a pad and began filling out forms of his own.

“Yeah, we’re gonna have to make sure you don’t do that then. You can’t just go around creating chemical waste every time you get sad. I’m going to have to get in contact with IT, set up some kind of cut off point with the cantina for you.”

Someone down the hall must’ve sanitized something because the odor of strong alcohol wafted into the room. It was all Earl could do to not empty his stomach a second time.

“Aye. That’s fair.”
