#supernovas — Public Fediverse posts

Pesquisadores criaram o método CIGaRS, que usa inteligência artificial para melhorar a análise de supernovas, aumentando a precisão das medições em cosmologia ao extrair informações de dados antes considerados irrelevantes.

A strange ‘chirp’ in a brilliant stellar blast points to a #magnetar
About a billion light-years away, an extraordinary stellar explosion lit up in the night sky. The blast, detected December 12, 2024, was some 30 times the brightness of a typical #supernova, putting it in a rare group of superluminous #supernovas. Now, #astronomers believe they know what made the explosion so bright — an extreme type of star called a magnetar.

"They conclude potential origins could be the Orion star-forming region that was located much closer to Earth long ago."

There's a lot going on in Orion, Betelgeuse for instance, though thankfully that going pop would be humbling rather than terminal.

#Scientists Just Got an Unprecedented Glimpse into the Nature of Reality
#GravitationalWaves are ripples in #spacetime that are produced by energetic cosmic events, such as #supernovas or mergers between #blackholes. Einstein predicted their existence in 1916 general theory of relativity, though he was doubtful humans could ever develop technologies sensitive enough to detect them. These waves oscillate at tiny distances that are thousands of times smaller than a proton.

Carl Sagan's "We're made of star stuff," confirmed.

"Astronomers have glimpsed the inner structure of a dying star in a rare kind of cosmic explosion called an “extremely stripped supernova”.
[...]
Their findings support our existing theories of what happens inside massive stars at the end of their lives – and how they have shaped the building blocks of the universe we see today."

How did so much ordinary #matter end up in the middle of nowhere? Vast amounts of #gas are ejected from #galaxies when massive #stars explode in #supernovas or when supermassive #BlackHoles inside galaxies "burp," expelling material after consuming stars or gas
"If the #universe were a more boring place, or the laws of #physics were different, you might find that ordinary matter would all fall into galaxies, cool down, form stars, until every proton & neutron were a part of a star," Connor said.

"[A]bout a decade ago, I was helping to refine a system for fabricating chips using extreme ultraviolet (EUV) light.
[...]
I realized that many aspects of this process have intriguing similarities to what happens during a supernova: a sudden explosion, an expanding cloud of plasma debris, and a shock wave that slams into a thin hydrogen environment. (Interstellar material consists mostly of hydrogen.)"

#Supernovas are one of the most violent events in the universe, and the force of the explosion generates a blinding flash of radiation, as well as shock waves analogous to sonic booms.

#Supernovas are bright.

So bright that when you hold a nuclear bomb directly to your eye - compared to that the sun going Supernova would be a billion times brighter.

Argon #atoms make up ~1% of our atmosphere and undergo almost no chemical reactions. They basically float around indefinitely. In 1967 Harlow Shapley noted that their permanence means we all literally share breath and have shared it with every human ever alive.

Argon-36 is the most common argon isotope in the universe. It’s often produced by stellar nucleosynthesis in #supernovas. In fact it was the first noble-gas #molecule detected in #space.

9 de enero, pero del año 1998: Dos equipos de colaboraciones #internacionales de #científicos anunciaron el descubrimiento de que las #galaxias se aceleran, se separan a velocidades cada vez más rápidas, al observar #estrellas antiguas y distantes en explosión.

Esta observación, nombrada como el "Avance del #año de 1998" por la revista #Science, implica la existencia de una propiedad misteriosa y autorepelente del espacio.

Investigadores de #Inglaterra, #Francia, #Alemania y #Suecia se encuentraban entre los miembros del Proyecto de Cosmología de #Supernovas con sede en el Laboratorio #Nacional de Berkeley y el Equipo de #Búsqueda de Supernovas High-z con sede en #Australia.

Chapter 2 is in the works. Honestly this time. #supernovascomic #supernovas #webcomic #comics #art #digitalart

Sin embargo ¿que pasa con las estrellas de masa intermedia, es decir entre ocho y diez masas solares? La teoría nos decía que estas forman una enana blanca que luego explota en un tercer tipo de supernova, la 'supernova por captura de electrones'. Pero recién la semana pasada se pudo confirmar que la supernova SN 2018zd, descubierta por un astrónomo aficionado en 2018, es un ejemplo de este tercer tipo.

Cabe aclarar que, si bien es la primera confirmada, puede no haber sido la primera observada: se cree que la supernova SN1054, observada hace casi mil años por astrónomos árabes y chinos, puede haber sido de este tipo. Esta supernova dio origen a la bellísima 'nebulosa del cangrejo', donde los restos de una estrella muerta reencarnan en la semilla de nuevos sistemas planetarios.

Oh wow. Phil Plait on a really big BOOM.

"This is the single most powerful and luminous confirmed supernova ever seen. [...] [I]t was emitting energy at a rate 100 billion times the Sun’s output."
