In Greek mythology, Andromeda (/ æ n ˈ d r ɒ m ɪ d ə /; Ancient Greek: Ἀνδρομέδα, romanized: Androméda or Ἀνδρομέδη, Andromédē) is the daughter of Cepheus, the king of Aethiopia, and his wife, Cassiopeia.

The Andromeda Galaxy is a barred spiral galaxy and is the nearest major galaxy to the Milky Way. It was originally named the Andromeda Nebula and is cataloged as Messier 31, M31, and NGC 224.

Jan 16, 2025 · Andromeda’s total population is estimated to be 1 trillion stars, with many less massive stars falling below Hubble’s sensitivity limit. Photographing Andromeda was a herculean task because the galaxy is a much bigger target on the sky than the galaxies Hubble routinely observes, which are often billions of light-years away.

Jan 23, 2025 · Astronomers are celebrating the completion of a 2.5-billion-pixel panoramic picture of the entire Andromeda galaxy. The team includes several UC Santa Cruz researchers who made significant contributions to the enormous photomosaic that combines some 600 snapshots taken by the Hubble Space Telescope over more than a decade and 1,000 orbits.

Jan 16, 2025 · Andromeda past and future. Though Andromeda and the Milky Way likely formed around the same time, the much larger Andromeda — with about a trillion stars versus the Milky Way’s 300 billion — has evolved differently. It has younger stars and unusual features, like coherent streams of stars, which imply that it had a more active recent star ...

Jan 24, 2025 · Andromeda Galaxy, great spiral galaxy in the constellation Andromeda, the nearest large galaxy. It is one of the few visible to the unaided eye, appearing as a milky blur. The Andromeda Galaxy is located about 2,480,000 light-years from Earth, and its diameter is approximately 200,000 light-years.

Jan 16, 2025 · Andromeda's total population is estimated to be 1 trillion stars, with many less massive stars falling below Hubble's sensitivity limit. Photographing Andromeda was a herculean task because the galaxy is a much bigger target on the sky than the galaxies Hubble routinely observes, which are often billions of light-years away. ...

Jan 16, 2025 · The target is the vast Andromeda galaxy that is only 2.5 million light-years from Earth, making it the nearest galaxy to our own Milky Way. Andromeda is seen almost edge-on, tilted by 77 degrees relative to Earth’s view. The galaxy is so large that the mosaic is assembled from approximately 600 separate fields of view taken over 10 years of ...

Sep 5, 2024 · Excluding the Large and Small Magellanic Clouds, visible from Earth’s Southern Hemisphere, the Andromeda galaxy is the brightest external galaxy visible in our night sky. And, at 2.5 million...
