This signal was picked up by the space-based SVOM monitor.<\/p>\n\n\n\n<p>Approximately 110 days later, scientists pointed the JWST at the same spot. They successfully separated the light of the explosion from its faint host galaxy, confirming that a supernova had indeed occurred.<\/p>\n\n\n\n<p>A \u201cSmoking Gun\u201d Dr. Antonio Martin-Carrillo, a co-author of the study, called this the \u201csmoking gun\u201d that connects the death of massive stars with gamma-ray bursts.<\/p>\n\n\n\n<p>\u201cAlmost every supernova ever studied has been relatively nearby to us,\u201d Martin-Carrillo explained. \u201cWhen we confirmed the age of this one, we saw a unique opportunity to probe\u2026 what type of stars existed and died back then.\u201d<\/p>\n\n\n\n<p>The most shocking finding was that this ancient explosion looks nearly identical to supernovae we see in the modern universe.<\/p>\n\n\n\n<p>Scientists previously assumed that stars in the early universe, which formed under very different conditions with fewer heavy elements, would explode differently. Instead, this distant star died in a way that is surprisingly similar to stars today. This suggests that the lifecycle of massive stars has remained remarkably consistent for billions of years.<\/p>\n\n\n\n<p>The team plans to observe the site again in one to two years. Once the supernova\u2019s light has faded, they will be able to clearly see the galaxy left behind to learn more about the environment where this star lived.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>An international team of astronomers has achieved a historic milestone in probing the early universe, using the James Webb Space Telescope (JWST) to detect a supernova\u2014the explosive death of a massive star\u2014at an unprecedented distance.
