The Milky Way [c] is the galaxy that includes the Solar System, with the name describing the galaxy's appearance from Earth: a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye.
Simulations show that the Milky Way and Andromeda are on a collision course, and are expected to collide in less than five billion years. During this collision, it is expected that the Sun and the rest of the Solar System will be ejected from its current path around the Milky Way. The remnant could be a giant elliptical galaxy. [12]
[25] [29] [30] The bar may be surrounded by a ring called the 5-kpc ring that contains a large fraction of the molecular hydrogen present in the Milky Way, and most of the Milky Way's star formation activity. Viewed from the Andromeda Galaxy, it would be the brightest feature of the Milky Way. [31]
Astronomers using the Gaia space telescope have located two ancient streams of stars that helped the Milky Way galaxy grow and evolve more than 12 billion years ago.
Astronomers used the James Webb Space Telescope to spot a Milky Way-like galaxy that formed soon after the big bang created the universe.
The Eris simulation is the first successful simulation to have resolved the high-density gas clouds where stars formed. [3] The simulation result consisted of a galaxy which is very similar to the Milky Way galaxy. Some of the parameters which were similar to Milky Way are stellar content, gas content, kinematic decomposition, brightness ...
While Earth is located about 26,000 light-years from what's known as the galactic center, the outer portions of the Milky Way are even further, at about 58,000 light-years from our galaxy's ...
It consists of two collections of galaxies in a "dumbbell" shape; the Milky Way and its satellites form one lobe, and the Andromeda Galaxy and its satellites constitute the other. The two collections are separated by about 800 kiloparsecs (3 × 10 ^ 6 ly; 2 × 10 19 km) and are moving toward one another with a velocity of 123 km/s . [ 3 ]
