Astronomers have captured a historic image of a massive star just 26 hours after it exploded, revealing the supernova's shape in unprecedented detail. The European Southern Observatory's Very Large Telescope in Chile pointed its cameras at the phenomenon, which was first detected in April this year.
The explosion is thought to be the result of a massive star running out of fuel, causing its core to collapse and surrounding shells of mass to fall inward before bouncing off and releasing an enormous amount of energy when it breaks through the surface. This event has been described as a "cosmic firework," with scientists eager to understand the underlying processes that drive these explosive events.
The supernova, known as SN 2024ggi, is located 22 million light-years away in the galaxy NGC 3621 and is thought to have originated from a red supergiant star with 12-15 times the mass of our sun. The team used a technique called spectropolarimetry to capture the supernova's geometry, which involves measuring the polarization of its light.
The resulting image shows that the initial blast was olive-shaped, with the material spreading outward and flattening as it interacted with surrounding matter. Despite being just one point in space, researchers were able to reconstruct the supernova's shape from this data, providing a unique insight into these cosmic events.
These findings have significant implications for our understanding of stellar evolution and the physical processes that lead to supernovas. According to Yi Yang, an astronomer at Tsinghua University, "the geometry of a supernova explosion provides fundamental information on stellar evolution and the physical processes leading to these cosmic fireworks." The discovery also challenges current supernova models, paving the way for further research into these powerful explosions.
The fact that scientists were able to capture this phenomenon in its earliest moments is a testament to the power of modern astronomy. By using advanced techniques such as spectropolarimetry, researchers can now gain a deeper understanding of these cosmic events and shed light on some of the biggest mysteries in the universe.

22 million light-years away and it's like, whoa! but what's with all these lights? are they, like, aliens or something? 
anyway, so the scientists were able to capture its shape after 26 hours? that's crazy fast! how did they even do that? was it like a big camera or something? and what's this spectropolarimetry thingy? sounds like some sci-fi stuff to me 
So basically, when the star runs out of fuel, its core collapses and then suddenly explodes, sending energy in all directions 
. The weird thing is that scientists can actually measure how it's spreading outwards, which helps them figure out what happened before the explosion 
.
... I mean, who wouldn't want to see a massive star go up in flames like a celestial fireworks display? 
But seriously, understanding supernovas could give us some insight into how stars evolve and eventually die, which is pretty cool 
.
. It's like they had X-ray vision or something 
.
just saw that news about supernova sn 2024ggi... wow they were able to get an image of it like 26 hours after it happened! that's insane 
?
It's like, we're talking cosmic firework here! 
The fact that they were able to capture the supernova's shape in unprecedented detail is super impressive. I'm loving how scientists are using spectropolarimetry to get a better understanding of these events. It's like, they're getting up close and personal with some seriously powerful stuff. 
and now they're gettin all the details on its shape and stuff. i'm lowkey obsessed with how they used spectropolarimetry to figure it out, that sounds like some super cool tech 
. i mean, 22 million light-years away is still crazy but its lit that they were able to get this info 
anyway, these scientists are rockstars using spectropolarimetry to get this crazy shape of the supernova 
. now they can study the geometry and all that jazz 
. The fact that researchers can capture such detailed images from light polarization is just plain awesome 
. It's moments like these that remind us why we're still so obsessed with exploring the universe 
it's just mind-blowing how fast those scientists were able to capture this historic image after the supernova exploded... like 26 hours is crazy fast! 
. and the fact that we're still learning so much about stellar evolution from these explosions is just wild 
. I'm also loving how it's challenging our current supernova models
