#Betelgeuse is a massive, highly variable red supergiant star in the constellation Orion that is nearing the end of its stellar life cycle and is destined to explode as a spectacular supernova visible from Earth.

ALMA rivela punti caldi di lunga durata sulla superficie ribollente di Betelgeuse

Un’immagine straordinariamente dettagliata ottenuta con (ALMA) rivela la superficie irregolare di Betelgeuse. Le osservazioni mostrano brillanti punti caldi (hotspots) e un contorno irregolare e ondulato, modellato dagli enormi moti che avvengono all’interno della stella.

#PPOD: This remarkably detailed view of #Betelgeuse, captured by the Atacama Large Millimeter/submillimeter Array (ALMA), reveals the uneven, bubbling surface of the famous red supergiant about 600 light-years away. Nearly 800 times larger than the Sun, Betelgeuse is covered by enormous regions of hot gas rising from deep within the star, creating the bright hotspots seen across its surface.

An article accepted for publication in the journal "Astronomy & Astrophysics" reports the results of observations of structures that are lasting longer than predicted in the atmosphere of the star Betelgeuse. A team of researchers used the ALMA radio telescope to obtain some of the most detailed views of Betelgeuse's surface ever obtained. This allowed them to study its really uneven surface and the structures within its atmosphere.

@esoastronomy : #Betelgeuse is around 1400 times larger 📏 than our Sun ☀️. Compared to the #SolarSystem, Betelgeuse would engulf all four terrestrial planets — #Mercury, #Venus, #Earth and #Mars — and even the gas giant #Jupiter https://www.eso.org/public/belgium-fr/images/potw1726b

Betelgeuse tiene compañía! Todo apunta a que una estrella (Siwarha) es la causa de una de las variaciones del brillo de nuestra querida gigante roja.

Gli astronomi hanno trovato la prova più convincente finora che Betelgeuse abbia una compagna

Finalmente gli astronomi hanno ottenuto prove concrete che Betelgeuse, una delle stelle più celebri del cielo notturno, non è sola.

An article published in the journal "Astronomy & Astrophysics" offers the best evidence yet for the existence of a companion to the star Betelgeuse. Independent observations will be needed to confirm the existence of the candidate Betelgeuse B. This study suggests it's a star with a mass between 2.6 and 3.1 times the Sun's.

Two of the authors of the new #Betelgeuse paper strengthening the case for a companion star are #AmateurAstronomers: in https://www.aavso.org/blog/aavso-observations-help-confirm-betelgeuses-long-suspected-companion the #AAVSO explains how their precise photometry of the star contributed.

New images reveal #Betelgeuse’s buddy #star
Borrowing imaging techniques from #exoplanet hunters, the team captured the dim light of the smaller star amid the light of the huge one. The resulting images are the most definitive detection of Betelgeuse’s buddy yet, the team reports in a paper to appear in #Astronomy & #Astrophysics, an ordinary star orbiting the famed supergiant.

There's every chance Betelgeuse B will be fired out of the system, on a wave of Supernova energy!
This is supernova we could see in daylight by the way, and it's due possibly within the lifetime of Humanity....that'll be something for us to freak out about I'm sure!
The red supergiant #Betelgeuse is destined to end its life in a violent core-collapse #Supernova, an event that will cause it to flash with the intensity of a half-moon and remain clearly visible in Earth's daylight sky for several months.

#Betelgeuse’s buddy leaves a wake in the giant #star’s atmosphere
Strongest evidence yet that a solar-mass object orbits the supergiant star
Signs of the smaller star’s trail around the red supergiant are the best evidence yet that Betelgeuse’s buddy actually exists.
“It confirms there really is an object there creating a wake, really, honestly, truly,” says astrophysicist Andrea Dupree, who presented the evidence at American Astronomical Society

Another photo from last night, different tree. The brightest "star" is Jupiter :)
Taken with my phone basically.
