Betelgeuse, which marks Orion the Hunter’s right shoulder, is a red supergiant star. In 1996, it became the first star other than the Sun to be directly imaged. This Hubble Space Telescope image shows the star’s atmosphere; the large, bright spot visible in the center is roughly twice as wide as Earth’s orbit around the Sun and 2,000 kelvins hotter than the surface of Betelgeuse.
