Betelgeuse Supernova — A Star’s Final Act The red giant Betelgeuse, one of the brightest stars in Orion, is nearing the end of its life — and when it goes supernova, the explosion could be visible from Earth even in broad daylight. This cosmic event could happen anytime, and it will shine brighter than the full Moon for weeks. Scientists are closely watching every flicker and shift, waiting for the moment it unleashes its final blaze. When it happens, we won’t just see a star die — we’ll witness

Imagine placing the massive star Betelgeuse in our solar system! 🌌 If Betelgeuse was in the center, it would extend far beyond Mars. 🪐🚀 This red supergiant is so huge, it would almost reach the orbit of Jupiter! Watch the reel to see just how huge Betelgeuse is compared to our familiar solar system. It’s a stunning perspective that shows the incredible scale of celestial bodies . . #space #nasa #science #astronomy #stars #galaxy #universe | Space Knowledge

Betelgeuse is one of the brightest and closest stars in our night sky. 🌟 But last fall, astronomers noticed the star dimming dramatically. Ultraviolet observations from Hubble suggest that the unexpected dimming was probably caused by a large amount of superhot material ejected into space. The material cooled and formed a dust cloud that blocked the starlight coming from about a quarter of Betelgeuse's surface!
