An Anti-Social Cosmic Explosion: Rethinking Dying Stars and Supernovas
What makes this explosion anti-social? A recent investigation into a spectacular cosmic explosion has raised fresh questions about how dying massive stars release energy and interact with their surroundings. The event, described by researchers as “anti-social” in the sense that its aftermath behaved differently than expected, calls into question long-standing ideas about how ejected debris…

Anti-Social Cosmic Explosion: Rethinking How Dying Stars Shape Their Surroundings
Unraveling a Cosmic Enigma A recent investigation into a violent stellar death—an explosion that would typically light up its surroundings—has challenged long-held assumptions about the relationship between ejected debris and the total energy released. The event, described by researchers as unusually isolated or “anti-social,” shows that a massive star can end its life in a…

Anti-social cosmic explosion: redefining how we understand dying stars
Introduction: A surprising twist in a familiar cosmic event For decades, scientists have linked the dramatic finale of massive stars—supernovae—to the energy they unleash as debris hurtles into surrounding space. Typical narratives describe a bright, outward pulse that lights up galaxies and leaves behind compact remnants like neutron stars or black holes. But a recent…

JWST Uncovers Hidden Doomed Star Behind SN 2025pht, Shedding Light on Red Supergiant Explosions
A New Look at a Silent Progenitor The James Webb Space Telescope (JWST) has offered astronomers a rare glimpse of a hidden star on the eve of its dramatic finale. In a study published in The Astrophysical Journal Letters, researchers report that the progenitor of the supernova SN 2025pht—an enormous red supergiant—was virtually invisible in…

Hidden ‘doomed’ star revealed by JWST could solve decades-old mystery
JWST spots a hidden giant on the brink of catastrophe The James Webb Space Telescope (JWST) has provided an unprecedented look at a massive red supergiant just before it exploded as a supernova. The discovery, announced in The Astrophysical Journal Letters, offers a crucial clue to a decades‑old astrophysical puzzle: why some red supergiants disappear…

Ancient supernova signature found in Pacific sediments
What the spike means A recent international study has uncovered an unusual spike in beryllium-10 (Be-10) within Pacific Ocean sediments. Be-10 is a radioactive isotope produced when cosmic rays collide with Earth’s atmosphere. Its presence in higher-than-normal amounts can act as a cosmic fingerprint, offering clues about dramatic astronomical events that may have influenced our…

Pacific Be-10 Spike Suggests Nearby Ancient Supernova
Overview: A surprising isotopic signal in Pacific sediments Scientists have identified an unusual spike in the radioactive isotope beryllium-10 (Be-10) in ocean sediments from the Pacific Ocean. Because Be-10 forms when cosmic rays strike Earth’s atmosphere, such a spike can act as a cosmic fingerprint, potentially recording a nearby stellar explosion in Earth’s distant past.…
