The Andromeda–Milky Way collision is a galactic collision predicted to occur in about 4.5 billion years between the two largest galaxies in the Local Group—the Milky Way (which contains the Solar System and Earth) and the Andromeda Galaxy.
Galactic Center. 17 45 40.04, −29° 00′ 28.1″. The Galactic Center, as seen by one of the 2MASS infrared telescopes, is located in the bright upper left portion of the image. Marked location of the Galactic Center. The Galactic Center is the barycenter of the Milky Way and a corresponding point on the rotational axis of the galaxy.
The rotation curve of a disc galaxy (also called a velocity curve) is a plot of the orbital speeds of visible stars or gas in that galaxy versus their radial distance from that galaxy's centre. It is typically rendered graphically as a plot, and the data observed from each side of a spiral galaxy are generally asymmetric, so that data from each ...
Like our home galaxy, the newly discovered ceers-2112 is a barred spiral galaxy, and it’s now the most distant of its kind ever observed. The bar at the center of the structure is made of stars ...
The Large Magellanic Cloud (LMC) is a dwarf galaxy and satellite galaxy of the Milky Way. At a distance of around 50 kiloparsecs (163,000 light-years), the LMC is the second- or third-closest galaxy to the Milky Way, after the Sagittarius Dwarf Spheroidal (c. 16 kiloparsecs (52,000 light-years) away) and the possible dwarf irregular galaxy called the Canis Major Overdensity.
Astronomers have released an image of the Milky Way that maps some of the largest structures in the galaxy, including nebulas and the galactic center. Gorgeous new Milky Way image maps our galaxy ...
Interacting galaxies ( colliding galaxies) are galaxies whose gravitational fields result in a disturbance of one another. An example of a minor interaction is a satellite galaxy disturbing the primary galaxy's spiral arms. An example of a major interaction is a galactic collision, which may lead to a galaxy merger .
Story at a glance. The center of our galaxy is visible in July and August for those in the Northern Hemisphere. A camera that allows you to take long-exposure photos can pick up more colors and ...
