Astronomers have completed an impressive 417-megapixel mosaic of the Andromeda galaxy using the Hubble Space Telescope, taking over a decade to finalize. This thorough celestial image encompasses around 200 million stars, which represents only a small segment of Andromeda's estimated one trillion stars. As noted by NASA, the extensive 2.5 billion pixel image serves as a vital tool for astronomers to understand the galaxy's historical events, including interactions with smaller satellite galaxies, thereby enriching our knowledge of galactic evolution.
Using the Hubble Space Telescope, researchers have developed a stunning 417-megapixel panorama of the Andromeda galaxy, showcasing over 200 million stars.
The 2.5 billion pixel mosaic will assist astronomers in piecing together Andromeda's history, revealing past events such as mergers with smaller satellite galaxies.
