— Douglas Adams, The Hitchhiker's Guide to the Galaxy. Both M32 and M110 have had encounters with M31 that they’ve come off worse from: a stream of stars was ripped away from M110 while Andromeda robbed M32 of a large part of its stellar disk at some point in the distant past. A spiral galaxy around 2.5 million light-years from us, it contains around a trillion stars. The Andromeda galaxy, our Milky Way's closest neighbor, is the most distant object in the sky that you can see with your unaided eye — but only on a clear night from a location with a very dark sky. “First extragalactic exoplanet may have been found”. It's also the closest to us, which makes it visible to the naked eye from here on Earth. 1. 2. The novel Andromeda Nebula by Ivan Yefremov is named after the Andromeda Galaxy, even though the galaxy itself is only mentioned once, towards the end of the book. It’s huge! https://www.newscientist.com/article/dn17287-first-extragalactic-exoplanet-may-have-been-found/. I simply believe that of the nearly countless number of stars in the universe, many of them must have planets able to sustain life. If you monitor it in a large … https://en.wikipedia.org/wiki/File:Andromeda_Galaxy_(with_h-alpha).jpg, https://www.nasa.gov/mission_pages/hubble/science/double-nucleus.html, https://ourplnt.com/wp-content/uploads/2017/02/Andromeda-in-the-sky.jpg, https://www.skyandtelescope.com/astronomy-news/the-star-that-changed-ouruniverse/, https://upload.wikimedia.org/wikipedia/commons/thumb/d/da/Andromeda_and_Milky_Way_collision.ogv/1200px--Andromeda_and_Milky_Way_collision.ogv.jpg. There were, however, speculations about the existence of extragalactic objects as early as 17thcentury, most notably by a French mathematician Pierre Louis Maupertuis. Andromeda Galaxy . The Andromeda galaxy is the largest galaxy in the Local Group, more than twice the size of the Milky Way. Locating the Galaxy Go away from the lights of the city. Like many other elliptical galaxies we observed, it has a black hole with more than 100 million solar masses in its center. The Andromeda Galaxy is one of the few visible to … **Add some fun to your life! The nearby galaxy Andromeda is speeding towards us at 250,000 mph. There were, however, speculations about the existence of extragalactic objects as early as 17th century, most notably by a French mathematician Pierre Louis Maupertuis. Also, there is only one sun. But in 2018, a group of researchers from Australia concluded that it might be as massive as the Milky Way, despite its size and number of stars. With an enormous diameter of around 220,000 light years across, Andromeda is over 2.5 … Work by Edwin Hubble, Henrietta Leavitt et al eventually proved Curtis right. The first concrete evidence of these hypotheses appeared in 1923, when the brilliant astronomer Edwin Hubble observed a Cepheid variable star within the Andromeda galaxy, a type of pulsating stars known as “standard candles” which are used to calculate the distance between celestial objects. Andromeda and the Milky Way are on a collision course. 6. Shapley believed that Andromeda and the Pinwheel galaxy were nebulas found within the Milky Way, based on the fact that if they weren’t, it would put Andromeda an ‘impossible’ multi-million-light-year distance from us. Andromeda contains three Messier objects – Messier 31 (Andromeda Galaxy), Messier 32 and Messier 110 – and has seven stars with known planets. It is set on a collision course with the Milky Way in approximately 4.5 billion years. However it is worth noting that the naked eye will only see the Central part of the galaxy. In terms of physical extent, the Andromeda Galaxy's disk diameter is well-measured, and spans 220,000 light-years across. He envisioned this be… Keep Calm 4 Football. Less than a 100 years after we proved it was, in fact, a galaxy, we were able to identify an exoplanet in the Andromeda galaxy. Aside from our own galaxy the Milky Way, Andromeda is probably the one that everybody knows, which makes sense as we’re pretty close to one another. Our Milky Way galaxy will survive in its current form a bit longer than some astronomers had thought, a new study suggests. The Andromeda Galaxy has an absolute magnitude of 3.4, which allows her to be the brightest object of the Messier catalogue. BA1 1UA Biology [edit | edit source] Physically, members of this species look like glowing humanoids with bright spherical white eyes and three-fingered hands. With the average distance between stars being 100 billion times larger than the average size of a star, there might be some gravitational disruptions between the stars within the two galaxies, but direct collisions are unlikely. Astronomers have known about its existence, but it was thought that it was a nebular cloud within the Milky Way. There is no concrete evidence of it, but astronomers do believe that a civilization similar to ours is broadcasting its presence. 2. How to choose your telescope magnification? Andromeda is bigger and denser; it may have one trillion stars and a diameter of 140,000 light years. ** **Let your day start perfectly with the best live radio that will take you to an incredible music journey. A father-daughter bond is explored.He is a 52 year old widower,an unemployed mechanic who rents a trailer to live in.She has been in an orphanage.Can they find a better life together? This strange double nucleus is thought to be a result of a collision of two protogalaxies about 10 billion years ago, but this hypothesis is largely discarded and we are still not sure what caused this strange formation. Both galaxies, together with 52 other, are part of the Local Group, one of many distinct groups of galaxies that are gravitationally bound to each other. The majority of the galaxies in the Local Group are dwarf galaxies orbiting the three largest –Andromeda, Milky Way and Triangulum. It is more than double the size of the second largest, our home – the Milky Way. Edwin Hubble settled the debate in 1925 when he discovered a type of variable star inside the Andromeda.
