La supernova SN 2024ggi explose… en forme d’olive ! Pour la première fois, on a capturé sa vraie géométrie au moment exact du breakout — bouleversant les idées reçues. www.science-et-vie.com/ciel-et-espa... #Space #Astrophysics #SN2024ggi #Supernova2025
A circa 22 milioni di anni luce di distanza da noi è esplosa #SN2024ggi. Il #VLT dell’ESO è riuscito a catturare la fase iniziale della supernova: un’osservazione talmente precoce – appena 26 ore dopo il primo rilevamento – da consentire di osservarne la forma: più simile a un’oliva che a una sfera.
Four tile image. Three tiles show the central structures of known nebulae and one photo shows a faint galaxy with a star that is annotated with a white arrow.
Zoom in inset of the central regions of the first three nebulae, showing the massive hot stars that create all that ionizing radiation that causes the hydrogen to emit that reddish colour, whilst carving out cavities in the cloud, and supernova #SN2024ggi from last night too.

Two tile image. Tiles are vertical. The left is a wide angle shot of a dense star field that has a galaxy in the centre. The right is a zoom in on the galaxy and has a white arrow annotated to one of the stars which is the supernova.
It’s been almost two months since I’ve done any #astrophotography (travel, conferences, etc.) so thought I’d check 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. 😍
📸🔭🧪
Seven tile image showing the same galaxy photographed in each tile. One of the stars in that galaxy is annotated with arrows or cross hairs.
And lastly, my backyard tracking of supernova #SN2024ggi in NGC 3621 continues … now got seven obs to visually compare temporal and colour evolution.
Off to the north tonight, so won’t see our southern skies for a month! 😥
#astrophotography 📸🔭
Image of a faint galaxy at the centre of a star field. There is an arrow annotated to one of the bright stars in the galaxy which is the supernova.
Five vertical narrow tiles, each showing a zoomed in section of an astrophotograph of a spiral galaxy’s edge. There is an arrow annotated to one of the bright stars in the galaxy which is the supernova on each of these images.
Got another 1.5 hours of light 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!
#Astrophotography 🔭📸
In the foreground is a blurry, bulky black object which is the telescope. This is a long exposure so the movement of the telescope makes it look dynamic. In the background at arcing star trails. Several straight and one curved bright arcs intersect the image, causing by the lights of passing aircraft overhead.
Tried to image #SN2024ggi in NGC 3621 tonight and I was competing with aircraft, extra extra light pollution from the festival of light, neighbours turning their lights on … shambles!
But the stars still shined through ….

Two tile image. Left shows wide field view of a fuzzy, soft galaxy in the centre surrounded by a field of stars. Right is a zoom in on the galaxy and shows an arrow annotating a single star which is the supernova.
Continuing on with imaging #SN2024ggi in NGC 3621 every Sunday from my backyard, and it is still very bright. Was able to get about an hour of data before the Moon came up and clouds rolled in.
This is about three weeks after the supernova was first detected. Star death in slow-mo is nice.
🔭🧪⭐️💥
Well, the moonlight did make for less detail (NGC 3621 is not as clear, and stellar field is much less prominent) from last week’s image, but #SN2024ggi still roaring brightly last night.
🔭📸⭐️💥
A small black telescope, sitting on a tripod. The set up is positioned on a sandstone pier with an iPad nearby. Surrounding and behind the peer are shrubs, plants and a fence. A bright moon hangs in the sky.
Currently imaging #SN2024ggi with Seestar S50, a week or so after my last image of the supernova in NGC 3621.
Let’s see how this will turn out relative to last week’s image, given we got a bright moon in the sky.

Two tile image features two vertical tiles. The first on the left is a wide angle shot of a spiral galaxy. It is small and resides within a dense star field. On the right is the zoomed in version, looking closer at Galaxy. An annotated arrow points to a white star which is the supernova.
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 and things started failing.
Still, pretty darn good for a 5cm aperture. Saturated the colours a bit to highlight blue-white hues of supernova!
⭐️💥🔭📸
Astro image of a spiral and many stars surrounding it. One star has an arrow pointed to it and is annotated with the supernova name.
Another awesome capture of #SN2024ggi, this time by @dylanodonnell.bsky.social and shared over on his insta account.
Gorgeous host galaxy dust lanes and spiral structure also visible in this one.
🔭📸
Grainy astro image of a galaxy’s core region with several bright stars surrounding it. One star is annotated with an arrow representing the supernova.
This is very noisy as it’s only 10 seconds of data, but even at such a short, single sub-integration, #SN2024ggi is roaring.
This thing is very bright, and probably gonna get a bit more brighter over days/weeks.
Note the idiot satellites which reflect light at dusk back down to Earth.
Astrophotograph of a spiral galaxy, with the bright core dominant and surrounded by a dense star field. One of the stars is annotated with cross hairs, indicating location of supernova.
Two tile image showing two spectrums of a supernova.
Andy Casely’s image of #SN2024ggi is here! Look at how blue the SN is!
Additionally, Andy used the SA100 grating filter (which has a resolution of R=100) to get some spectra (calibrated spectrum on bottom).
How cool is it that people can do this from their backyards?
