Nobody tell Alan Davies.

667, rok temu do astronomy w Hubble captures a new view of galaxy M90

Somewhen in there are creatures we’d really get along with were it not for the 58.71M light years between our galaxies, and the unlikelihood we both exist as simultaneous civilizations.

I don’t think there are many black holes in Rome. But I suppose they really want to make sure.

I dunno about giant. Looks pretty small from here.

oh damn, maybe they’ll fuck up inflation again 🥳

Brunbrun6766, rok temu do astronomy w Discovery of second ultra-large structure in distant space further challenges our understanding of the universe

Doubt, something unknown? Sure. Structure? Doubt.

“Structure” in this case means “big glob of galaxies slightly closer together than other globs”

halcyoncmdr, rok temu

In astronomical terms structure doesn’t mean a building of any kind.

Great article, but that “summary” diagram from the original author is garbage lol

Gork, rok temu do astronomy w New study shows Small Magellanic Cloud is actually two smaller galaxies

Hmm. So now we should have Small Magellanic Cloud and Small Magellanic Cloud^2

The Trisolarans made their dark domain.

TauZero, 2 lata temu do astronomy w Black holes could come in 'perfect pairs' in an ever expanding universe

Oh! They don’t mean that black holes must come in perfect pairs! The headline makes it sound like it’s about wormholes across vast distances. No! What they’ve found is a stable “orbit” solution for the two-body problem. Normally when you place two bodies anywhere in an empty universe, they will gravitate towards each other until they collide. But in a universe with dark energy, there is some perfect distance between them, where the accelerating expansion perfectly counterbalances the accelerating attraction. They’ve used general relativity math to actually calculate such an arrangement.

The “stable” orbit in this case is the same kind of stable as a pencil balanced on its sharp tip - if it tilts even slightly one way it will fall out of control. Although they tantalize the idea that they might be able to make it truly stable against small perturbations once they finish their spinning black hole solution.

I would like to have known some specific numbers examples! Like if you have as much dark energy as our universe, and two 10-solar-masses stellar black holes, how far apart would that be? Is it like 1Ly or 1MLy? How far for two 10-million-solar masses supermassive black holes? The formulas they created should give the exact answer but I am not skilled enough to substitute the correct numbers for the letters.

stevejon, 7 dni temu do astronomy w Boeing's troubled capsule won't carry astronauts on next space station flight

Thanks for sharing this update — it’s disappointing to hear the Boeing capsule won’t be flying astronauts to the space station on the next mission. Safety has to come first, but delays like this remind us how challenging and complex human spaceflight really is. Just like when considering a Botox Treatment in Acton, careful planning and attention to detail are essential for safe and successful outcomes. It’ll be interesting to see how Boeing addresses the issues and what steps NASA takes to keep the program on track. For personal care enthusiasts, treatments like a Derma roller lip also highlight how precise technique can make a big difference in results, even in completely different fields.
