Astronomers have identified a small companion star, named Siwarha, that is disturbing the atmosphere of the red supergiant Betelgeuse, explaining its unusual brightness changes. Using eight years of data from NASA's Hubble Space Telescope and ground observatories, researchers confirmed the companion's presence through a visible wake of dense gas. The discovery, announced at the American Astronomical Society meeting, sheds light on the evolution of massive stars.

The NASA/ESA Hubble Space Telescope has captured a stunning image of NGC 6000, a spiral galaxy 102 million light-years away in the constellation Scorpius. The picture highlights stars of varying ages, from blue young clusters to a golden older core, while revealing faint remnants of past supernovae. An asteroid photobombed the shot, adding streaks to the cosmic scene.
