Found: the most powerful explosions in the known universe.
"Extreme nuclear transients" likely happen when a massive star is shredded by a supermassive black hole. The black hole hides in gravitational darkness until it's silhouetted by the remains of its victim.

#delToro and #UAE didn't respect the pink jersey. As a leader you have both responsibilities and rights others don't. Yesterday they didn't fulfil their responsibility (to defend the jersey). Next time when they have the jersey and have a mechanical they will ask for the group to wait - because the leader has a problem. Yesterday they set a precedent that allows other teams to ignore them. #giro
@cdarwin after Greece fiasco EU set a rule that all states must have debt below 60 percent of GDP and deficit below 3%. USA is now double that

Thorough analysis of satellite reentries over the last 5 years, and how they were affected by the May 2024 solar storm: https://arxiv.org/pdf/2505.13752
Personally, I think the paper has way too much of a tone of "wow look at all this great reentry data! We can learn so much about satellite drag!" and not nearly enough "Holy shit guys, that's a lot of metal burning up in the atmosphere, maybe this is a bad idea?"
@lehtimaeki exactly because of this reasons I find it amazing that there are people listening to music or podcasts while running

“Why do we even plan on doing great things if, on a whim, we can just decide ‘nah’?” the senior space scientist says. “These things take a generation to build and enable multiple generations of scientists. They should not be blithely thrown away.” https://www.scientificamerican.com/article/nasas-next-major-space-telescope-is-ready-to-launch-trump-wants-to-kill-it/

Am 19. März 2025 hat @ec_euclid seinen ersten großen Datensatz veröffentlicht, und darin steckt weit mehr als nur beeindruckende Aufnahmen tiefer Himmelsfelder mit insgesamt 26 Millionen Galaxien: Bei vielen sind feinste Strukturen zu sehen, außerdem wurden Form und Entfernung von über 380.000 Galaxien bestimmt.
@knud verrät uns morgen Abend um 19 Uhr live bei Astro & Co, was man aus diesen Daten lernen kann
