Abstract
Closer to home, astronomers using the Hubble Space Telescope recently took a close‐up photograph of the red supergiant star Betelgeuse, providing astronomers with their first direct look at the surface of a star besides the Sun.Andrea Dupree of the Harvard‐Smithsonian Center for Astrophysics and Ronald Gilliland of the Space Telescope Science Institute presented pictures of Betelgeuse revealing an extended atmosphere and a surface marked by a bright spot more than 10 Earths wide and as much as 2000 K warmer than the rest of the surface.
