Bildunterschrift:
This wide-field image shows the region of the sky surrounding Alpha Centauri, the closest star system to our Solar System, located just over 4 light-years from Earth in the constellation Centaurus.
At the center of the image, Alpha Centauri appears extremely large and bright. However, this size is not its true physical size. The star looks oversized because its intense light spreads out when passing through the telescope’s optics and the photographic material used to record the image.
Alpha Centauri is not a single star, but a star system made up of three stars: Alpha Centauri A and Alpha Centauri B, which are similar to our Sun and orbit each other, and Proxima Centauri, a smaller red dwarf star that orbits farther away and is the closest individual star to Earth after the Sun. Alpha Centauri A and Alpha Centauri B are too close together to be resolved in this image so appear as one star in the center. Proxima Centauri is not shown here, it is just off the bottom right corner of this image. If it were shown it would be difficult to pick out from the mass of stars of similar brightness.
