Previous thread is previous
Apparently, "giant sun dogs" doesn't refer to a D&D monster type. The photos are still interesting, though, and there's enough description as to why it happens to elevate the article to at least pop-sci level.

Want to lob rocks at people you don't like and see what happens? Try the Asteroid Launcher.

Snakes have clitorises, and scientists finally found them
It might have taken this long because in the past it was male scientists who were looking for them...

Throttleable solid rocket fuel
non-embedded
Also covers a liquid monopropellant developed by the same company, since apparently even the usually extremely stable HIPEP (the first stuff) won't stop burning at SRB scale. The energy density and lack of sloshing around makes it good for smaller applications like satellite stationkeeping motors though, and apparently also practical effects for movies.

Ring system discovered around dwarf planet Quaoar leaves astronomers puzzled
Quote:The Roche limit states that ring systems can only form within a distance where the tidal forces from a larger body are more powerful than a smaller object's own gravitational forces. In short, debris captured inside a planet's Roche limit will be ripped apart and compressed into a ring system. Any material outside this distance, however, will more likely stick together under gravity and form a moon instead.
Quaoar, however, breaks this rule. Its ring system is intact at orbits at a distance over seven times the dwarf planet's radius. Saturn's ring system is located at a distance only three times its radius, for comparison. Now astronomers are puzzled over how such a ring system can survive so far from its parent body.

Gorilla sized penguins existed 60 million years ago
These are estimated to have weighed 340 lbs (previous record holder is 260 lbs). Not enough remains to determine the height yet.
The Mountains of Madness aren't in Antarctica, they're in New Zealand. Teliki-li! Teliki-li!

New Theory says Black Holes are the source of Dark Energy
RE: Weird & Interesting science, take 2 - Dartz - 02-16-2023
It's all about Black Holes and Gravity warping space time and causing space to expand around them or some shit.
Do Physics points work like Mythos points?

Epidural Stimulators give benefits for stroke victims
Small pilot study (2 people) using epidural stimulators (implanted electrical stimulators in spine normally used for pain control) regain hand and arm movement years after stroke.
The stimulators have shown a lot of potential in SCI patients (works in the basic science side of a department doing a lot of work with the stimulators)

a 'glitch' in an old Hubble photo turns out to be a supermassive black hole streaking through intergalatic space and leaving a trail of stars behind it that stretches 200,000 lightyears
RE: Weird & Interesting science, take 2 - hazard - 04-07-2023
Moving fast enough to go from Earth to the Moon in 14 minutes, too. A quick and dirty calculation tells me it's moving at about 0.16% the speed of light. And the trail is 200 000 light years long, so it was shot out 125 millions years or so ago.
Oh, and apparently there is a binary black hole system shot out the other side of the galaxy, with no evidence of a black hole in the center of the galaxy they came from.

From that same site, an article about radio signals plausibly possible to have been generated by intelligent life, from a goldilocks zone earthlike planet about 130ly away

I remain skeptical, and even if true it's unlikely to have any practical impact within our lifetimes. Well, unless the Dark Forest hypothesis is right and we manage to decode them into reports of the invasion there before the Boogies get around to us...

Just remember that pulsars were once speculated to be produced by intelligent beings before we figured out what was really going on.
