☄️ James Webb reveals neutron star hidden inside debris of exploding star

Astronomers using James Webb Space Telescope (JWST) data confirm a neutron star in the 1987A supernova, the only naked-eye visible one in 400 years. The recent findings shed light on the aftermath of such cosmic explosions.

Located in the Large Magellanic Cloud, a satellite galaxy of the Milky Way, Supernova 1987A has intrigued scientists for decades, offering valuable insights into the explosive end of massive stars in today’s Must Read.

Astronomers from Stockholm University, observed Supernova 1987A using James Webb’s infrared imagers, employing spectroscopy to analyze the gas cloud's composition. They detected emissions lines from highly ionized argon and sulfur gas, indicative of a bright source of ultraviolet and X-ray radiation, consistent with a neutron star rather than a black hole.

These observations provide compelling evidence for the presence of a neutron star in Supernova 1987A. This cataclysmic explosion, first detected in 1987 via neutrino sensors on Earth, was swiftly followed by the observation of light from the supernova, hinting at the formation of a neutron star, though it was uncertain if it later collapsed into a black hole.

Decades after the atomic bombing of Hiroshima in August 1945, researchers have uncovered fresh insights into the aftermath. The study revealed unusual fallout debris called Hiroshima glasses, formed from vaporized bomb materials and the surrounding landscape. Researchers from Université Paris Cité, France, analyzed these glasses' chemical and isotopic compositions, revealing they formed through rapid condensation within the nuclear fireball, akin to the formation of the solar system's earliest solids.
