Galaxy- A huge collection of stars gas and dust . 2.) The Canis Major Dwarf Galaxy is closer to the sun than Sagittarius A*, the centre of our galaxy. Sciences, Culinary Arts and Personal The tails and loops are characteristic of a post-merger. The merging will change completely the structure of both galaxies and in the end, it will be a completely new galaxy.

Explanation: What is the closest galaxy to the Milky Way? At the moment, the Milky Way is colliding with the Canis Major Dwarf galaxy. Observations show that the galaxies collided about 700 million years ago. These include Carina Dwarf, Draco Dwarf, and Leo II Dwarf. In this video, we will talk about the closest dwarf galaxy to our own Milky Way and discuss its future. The gravitational pull of both colliding stars can interact with this materials, creating friction and shock waves that can ignite the formation of new stars. This finding strongly suggests that the Canis Major dwarf galaxy is a building block of the Galactic thick disc, that the thick disc is continually growing, even up to the present time, and that thick disc globular clusters were accreted on to the Milky Way from dwarf galaxies in co-planar orbits. Some Milky Way globular clusters are loosely grouped around the nucleus of the Canis Major dwarf, and at least some of them may have their origin in the halo of this small galaxy, and may represent the remnant of its former globular cluster system: M79, NGC 1851, NGC 2298, and NGC 2808. The Canis Major Dwarf galaxy is so called because its small. These include Carina Dwarf, Draco Dwarf, and Leo II Dwarf. Now it’s stream of gas and dust surrounding the Milky Way. No, the Canis Major Overdensity (aka Canis Major Dwarf Galaxy) is not part of the Milky Way Galaxy.

Distance Learning Opportunities for Educators and Students. The Canis Major Dwarf is even closer (42,000 light-years away) and equally disturbed. Another dwarf galaxy surrounding the Milky Way is the Sagittarius Dwarf. Even so, shapes, dimensions, and speeds of different galaxies can create different outcomes but this simulation is the closest, yet, we can get to observe such an amazing dance between giants. The Milky Way Colliding with Dwarf Galaxies. Brant Robertson (Caltech) and Lars Hernquist (Harvard Univ.) Composite image from the Chandra X-ray Observatory (blue), the Hubble Space Telescope (gold and brown), and the Spitzer Space Telescope (red). Should humanity have survived that long and still be around, they wo… The process takes billions of years, and although we won’t be able to record a whole collision in our lifetime, the Hubble Space Telescope has given us glimpses of various galaxies around the universe at different stages of their collision. Canis Major Dwarf Galaxy Vocabulary Terms- 1.) It is located about 25,000 light-years away. The new answer to this old question is the Canis Major dwarf galaxy. The Canis Major Dwarf, classified as an irregular galaxy, went undetected for many years because of this dust in the Milky Way's atmosphere. For example, there's some evidence the Magellanic Clouds might merge with the Milky Way. "Thus," the researchers wrote in their paper, "we argue that Antlia 2 is the likely driver of the observed large perturbations in the outer gas disk of the Galaxy." The Andromeda galaxy has a diameter of 220,00 light years, making it much bigger than our Milky Way at 100,000 light years in diameter. It was discovered in 1994 and just like the Canis Major dwarf galaxy, the massive pull of the Milky Way’s gravity has been tearing it apart over billions of years. I just read about this and have several questions for my learned ya members (wow, some of you know your stuff). No, the Canis Major Overdensity (aka Canis Major Dwarf Galaxy) is not part of the Milky Way Galaxy.
