For six months in the year 1181, a dying star streaked across the night sky. The striking object appeared as bright as Saturn near the constellation Cassiopeia and was recorded as a “guest star” in… Read More »
The secrets of supernova star explosions may be hidden in dust scattered across the moon, and a team of scientists from the China Institute of Atomic Energy (CIAE) has developed a new way to uncover these clues of star death. The research could help scientists get a clearer picture of how stars die and provide… Read More »
Scientists have discovered strong evidence that there are some. big stars They end their existence not with a bang but with a whimper and sink into a swamp. black hole Without the light and anger of a being, their own actions supernova. To understand why this matters, we need to start with a crash course… Read More »
While examining a nearby supernova with NASA’s Fermi gamma-ray space telescope, scientists uncovered a larger mystery in an effort to discover how these stellar explosions fire charged particles called cosmic rays. The team found that the supernova, called SN 2023ixf, was completely devoid of gamma-ray emissions, which should be present when cosmic ray particles are… Read More »
Scientists have discovered a rare stardust particle resulting from the explosive supernova death of a distant star. This spot appears to be locked inside an ancient meteorite. The dust grain, however small, can help tell the story of the life, death and rebirth of stars that spans almost the entire 13.8 billion-year history of the… Read More »
Scientists may have discovered how a supernova relatively close to Earth was adorned with a remarkable “string of pearls” formation. Supernova 1987A (SN 1987A) represents the remnants of a massive cosmic explosion that ripped apart a massive star and left behind a neutron star surrounded by stellar material. It is located in a satellite galaxy… Read More »
Astronomers using the James Webb Space Telescope (JWST) have ended nearly a decade of celestial hide-and-seek after discovering a neutron star in the debris of a star explosion. Supernova 1987A represents the remains of an exploded star that once had a mass 8 to 10 times that of the Sun. It is located about 170,000… Read More »
Astronomers have discovered a hitherto unknown source of cosmic dust. Why is it important to keep track of this powder? These particles basically serve as building blocks for stars. The international team found that such dust could be created by a type of cosmic explosion that occurs when a dead white dwarf star ejects material… Read More »
If aliens are synchronizing their signals with the light from supernova 1987A, then search for extraterrestrial intelligence (SETI) is handling the case. Scientists at the institution say they can find such signals by looking for them in a place called the “SETI Ellipsoid”. About 167,600 years ago, a blue supergiant star exploded. supernova inside Large… Read More »
