Betelgeuse is the tenth brightest star in the night sky and the second brightest star found in the constellation Orion, located at the eastern shoulder of the hunter. At near-infrared wavelengths, however, the rust-colored star is the brightest star in the sky. Its brightness, position, and color make this star visible to the casual observer ...
Aug 25, 2022 · Betelgeuse is the 10th brightest star in the night sky and marks Orion's right shoulder (his left shoulder from our point of view). It is a red supergiant, an engorged monster that would stretch out to the orbit of Jupiter if it replaced the Sun in our solar system. Betelgeuse is well on its way to ending its life by detonating as a cataclysmic ...
Aug 13, 2020 · Betelgeuse is a variable star that expands and contracts, brightening and dimming, on a 420-day cycle. Hubble's ultraviolet-light sensitivity allowed researchers to probe the layers above the star's surface, which are so hot — more than 20,000 degrees Fahrenheit — they cannot be detected at visible wavelengths.

Apr 12, 2024 · Betelgeuse would be the closest supernova ever observed by humans. When Betelgeuse explodes, it will shine as brightly as the half-Moon for over three months. People would be able to see it in the daytime sky for about a year, and it would remain visible to the naked eye at night for several years as it gradually fades.
Jun 29, 2020 · Artwork: Betelgeuse is a red supergiant star, nearly 1,000 times larger than the Sun. Astronomers say big cool patches on a "supergiant" star close to Earth were behind its surprise dimming last ...
