Many cosmic events occur in space<\/a> and sometimes surprise astronomers. This is the case of these scientists<\/a> who observed the first moments of a supernova<\/a> shock wave. <\/p>\n

Therefore, it is necessary to turn to the supernova 2024ggi, located in the spiral galaxy NGC 3621<\/a>, about 22 million light-years from Earth<\/a>. When it exploded on April 10, 2024, astronomer Yi Yang of Tsinghua University in Beijing requested observation time on the Very Large Telescope<\/a> (VLT) in Chile. <\/p>\n

And according to him, this supernova<\/a> had a mass between 12 and 15 suns.\u00a0In other words, it was a red supergiant 500 times larger than our sun, which became a neutron star after this event.\u00a0 <\/p>\n

Thus, it is with the help of the Very Large Telescope’s FORS2 spectrograph<\/a> that astronomers<\/a> used a method called spectropolarimetry to observe this explosion, as Lifan Wang explains:\u00a0<\/p>\n

\n

“Spectropolarimetry delivers information about the geometry of the explosion that other types of observation cannot provide because the angular scales are too tiny.”<\/p>\n<\/blockquote>\n

According to the results obtained, the shape of the explosion was flattened, and it spread symmetrically. And surprisingly, it did not change its form after colliding with a ring of circumstellar material. <\/p>\n

If this is a first, this discovery will allow us to better understand our universe<\/a> and the events that take place there. And that\u2019s not all, because new discoveries could be made in the coming months and may provide new answers.<\/p>\n
