Dos_Box Posted March 26, 2025 Posted March 26, 2025 This looks exciting (if it happens) - https://dailygalaxy.com/2025/03/blaze-star-explode-see-with-naked-eyes/ Quote For the first time in nearly a century, Earth’s night sky may soon be lit up by one of nature’s rarest celestial events: a nova visible to the unaided eye. At the heart of this cosmic countdown is the Blaze Star, or T Coronae Borealis—a binary star system nestled within the elegant arc of the Northern Crown. After decades of quiet buildup, astronomers believe it could erupt any night now. If it does, stargazers around the world could witness a “new star” suddenly appearing where darkness reigned the night before. And while the exact date is uncertain, a recent analysis from astrophysicist Jean Schneider at the Paris Observatory suggests a possible eruption on March 27, 2025—or potentially later this year. 1
6Foot2 Posted March 26, 2025 Posted March 26, 2025 * Not a supernova, but a nova—a temporary thermonuclear outburst on the surface of a white dwarf in a binary system, leaving the star intact to repeat the cycle. A white dwarf is siphoning hydrogen from a red giant companion until it ignites, roughly every 80 years. Its last outburst was in 1946, and the next "eruption" (nova) is expected soon... 😃 1
6Foot2 Posted March 26, 2025 Posted March 26, 2025 Not a white hole. There are two stars, one large and one small. The small one is pulling matter from the surface of the large one (the gravitational attraction of the large one is lower at its surface, and so the material there is less strongly bound) The infalling matter accumulates on the surface of the smaller star until it ignites. After that, the cycle starts again.
