Formally known as a star, get to know Supernova SN 2024ggi, which was captured by the European Southern Observatory (ESO) pointed its Very Large Telescope (VLT) in Chile just moments after it went supernova.
Researchers confirmed the initial blast is olive-shaped. (the image below is an artistic representation) https://gizmodo.com/this-is-what-a-star-looks-like-just-26-hours-after-it-explodes-2000684424 #Space #Stars #SuperNova #SN2024ggi #ESO #VLT #Astromony

An article published in the journal "Science Advances" reports the first reconstruction ever of the shape of a Type II supernova in its early stages. A team of researchers led by Professor Yi Yang of Tsinghua University in Beijing, China, used observations conducted with ESO's Very Large Telescope (VLT) in Chile to study the supernova cataloged as SN 2024ggi on April 11, 2024, the day after the explosion began.

"
Einzigartige Form einer Sternexplosion nur einen Tag nach ihrer Entdeckung ermittelt
"
".. VLT .. hat einen Stern kurz nach seinem explosiven Tod beobachtet .. als d. Druckwelle d. Sternoberfläche durchbrach. Zum ersten Mal konnten Astronominnen u. Astronomen d. Form d. Explosion in ihrer frühestmöglichen, kurzlebigen Phase bestimmen. .."

Since it has been almost two months since I’ve done any #astrophotography (travel, conferences, etc.) last night I also went back and checked in on NGC 3621 and see how the supernova #SN2024ggi and it is considerably more yellow from when we first imaged it back in April.
Spectral and temporal evolution. 😍
Okay, main scope has been serviced and was taken off the fork mount and is now mated to the fancy new mount.
Collimation is in my future (this was expected) as the stars are quite 🤪
1 minute exposure of supernova #sn2024ggi in NGC3621.
Got another 1.5 hours of light last night from nearby(ish) galaxy NGC 3621 which features the recent supernova #SN2024ggi
Have now been grabbing light from this event over a few months and can see its colour/flux temporal evolution.
Caught it with VIVID’s extreme light pollution too! (VIVID is a very popular festival of light here in Sydney in which light pollution increases by several orders of magnitude!)
Continuing on with my weekly capture of #SN2024ggi on Sunday evenings. Supernova still going strong in NGC 3621.
Stellar death in slow-mo. Relaxing. Unless you are there being destroyed by the enormous fireball of an entire star collapsing in on itself and violently exploding. That would not be relaxing.
Here’s a second night of imaging #SN2024ggi using Seestar S50 from my backyard.
Got about 2 hours of data but then NGC 3621 crossed the meridian near the zenith and things started failing.
Still, pretty darn good for a 5cm aperture. Saturated the colours a bit to highlight blue-white hues of supernova!
