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 . Andromeda has a D 25 isophotal diameter of about 46.56 kiloparsecs (152,000 light-years ) [ 8 ] and is approximately 765 kpc (2.5 million light-years ...
NASA recently released images of the Andromeda galaxy, an empire of stars, that is the Milky Way galaxy's closest neighbor. This photo shows the Milky Way as seen from Black Balsam, mountain range ...
Zooming In on the Andromeda Galaxy, also known as Gigapixels of Andromeda, is a 2015 composite photograph of the Andromeda Galaxy produced by the Hubble Space Telescope. It is 1.5 billion pixels in size, and is the largest image ever taken by the telescope. [1] At the time of its release to the public, the image was one of the largest ever ...
The Sun, the orbit of Earth, Jupiter, and Neptune, compared to four stars (Pistol Star, Rho Cassiopeiae, Betelgeuse, and VY Canis Majoris) Overview Although red supergiants are often considered the largest stars, some other star types have been found to temporarily increase significantly in radius, such as during LBV eruptions or luminous red ...
In comparison, the Sun is about 4.6 billion years old. The star is slightly metal-rich, with a metallicity ([Fe/H]) of 0.09, or about 123% of the solar amount. Its luminosity (L ☉) is 3.57 times that of the Sun. The star's apparent magnitude, or how bright it appears from Earth's perspective, is 4.09. Therefore, Upsilon Andromedae can be seen ...
Upsilon Andromedae d (υ Andromedae d, abbreviated Upsilon And d, υ And d), formally named Majriti / m æ dʒ ˈ r aɪ t i /, is a super-Jupiter exoplanet orbiting within the habitable zone of the Sun-like star Upsilon Andromedae A, approximately 44 light-years (13.5 parsecs, or nearly 416.3 trillion km) away from Earth in the constellation of Andromeda.
NGC 512, also occasionally referred to as PGC 5132 or UGC 944, is a spiral galaxy in the constellation Andromeda. [2] It is located approximately 217 million light-years from the Solar System [ 4 ] and was discovered on 17 November 1827 by astronomer John Herschel .
The possible exoplanet would have a mass of 6.34 Jupiter mass.If confirmed, it would be the first exoplanet found in another galaxy. [4] A similar event was seen in 1996 when a team of astronomers discovered an anomalous fluctuation in the Twin Quasar's lightcurve that seemed to be caused by a planet approximately three Earth masses in size in the quasar's lensing galaxy YGKOW G1.
