In 2012, a microquasar, a radio burst emanating from a smaller black hole was detected in the Andromeda Galaxy. Galileo Galilei used his telescope for the very first time in 1610 to resolve a band of light into individual stars. Fueled by gravity, the two galaxies are hurtling toward one another at 402,000 kilometers per hour. Creationists have proposed many solutions. Some of them are among the most densely populated globulars ever seen. They are passionate about turning your everyday moments into memories and bringing you inspiring ideas to have fun with your family. [75] A possible cause of such a warp could be gravitational interaction with the satellite galaxies near the Andromeda Galaxy. [74], A study in 2005 by the Keck telescopes shows the existence of a tenuous sprinkle of stars, or galactic halo, extending outward from the galaxy. The Andromeda Galaxy (IPA: /ndrmd/), also known as Messier 31, M31, or NGC 224 and originally the Andromeda Nebula, is a barred spiral galaxy with the diameter of about 46.56 kiloparsecs (152,000 light-years)[8] approximately 765kpc (2.5million light-years) from Earth and the nearest large galaxy to the Milky Way. At a billion. You can also use the Great Square of Pegasus. The Andromeda Galaxy is about 2.9 x 10^6 light-years from Earth. Science news, great photos, sky alerts.

Spiral nebulae, like Andromeda, were named from their spiral shapes. Distance to Andromeda - Universe Today It's a pretty. Andromeda Galaxy Facts - Space Facts During this epoch, its rate of star formation would have been very high, to the point of becoming a luminous infrared galaxy for roughly 100 million years. Its peculiar close companion, M32, shows a structure that indicates that it was formerly a normal, more massive galaxy that lost much of its outer parts and possibly all of its globular clusters to M31 in a past encounter. An estimation done with the help of Spitzer Space Telescope published in 2010 suggests an absolute magnitude (in the blue) of 20.89 (that with a color index of +0.63 translates to an absolute visual magnitude of 21.52,[a] compared to 20.9 for the Milky Way), and a total luminosity in that wavelength of 3.641010L.[69]. Astronomers didn't figure out how to break the Andromeda spiral nebula down and locate individual stars until the 20th century. Andromeda Galaxy (NGC 224, Messier 31) Facts - Universe Guide They have features that suggest they are what is remaining of smaller galaxies that were taken over or 'eaten,' as astronomers call it, by the giant center galaxy, and also clouds of M31 stars that were ejected by the intense tidal force caused by the collision. In the sci-fi series "Star Trek," spaceships rapidly travel from one part of the universe to another using warp drives. This galaxy has an elliptical shape, and its orbit passes over the galactic poles of the Milky Way. Utilizing scientific notation: change distance in light years to . Right now, we know that if there is any offset, its pretty small (less than the size of a pixel on the Hubble Space Telescopes detector). The stars lie at a distance of 2.5210^60.1410^6ly (1.59410118.9109AU) and the whole Andromeda Galaxy at about 2.510^6ly (1.61011AU). Just squeeze a bunch of stars into ball called a globular star cluster and your eyes can telescope across 25,000 light-years.
