Hace 4 días · A supernova is the biggest explosion that humans have ever seen. Each blast is the extremely bright, super-powerful explosion of a star. An illustration of one of the brightest and most energetic supernova explosions ever recorded.
A supernova (pl.: supernovae or supernovas) is a powerful and luminous explosion of a star. A supernova occurs during the last evolutionary stages of a massive star, or when a white dwarf is triggered into runaway nuclear fusion.
These stars end their evolutions in massive cosmic explosions known as supernovae. When supernovae explode, they jettison matter into space at some 9,000 to 25,000 miles (15,000 to 40,000 ...
19 de jun. de 2023 · A supernova is what happens when a star has reached the end of its life and explodes in a brilliant burst of light. Supernovas can briefly outshine entire galaxies and radiate more energy than...
14 de mar. de 2023 · The rare sight of a Wolf-Rayet star – among the most luminous, most massive, and most briefly detectable stars known – was one of the first observations made by NASA’s James Webb Space Telescope in June 2022. Webb shows the star, WR 124, in unprecedented detail with its powerful infrared instruments.
22 de feb. de 2024 · Within hours, a ‘new’ star blazed bright enough to be visible to the naked eye. It was the closest and brightest supernova observed since 1604, at the dawn of the age of the telescope.
10 de dic. de 2023 · Mysterious features hide in near-infrared light. Like a shiny, round ornament ready to be placed in the perfect spot on a holiday tree, supernova remnant Cassiopeia A (Cas A) gleams in a new image from NASA’s James Webb Space Telescope.
