Closest galaxy to milky way

Once I accidentally took a photo of one of the most important stars in the Universe… Andromeda Galaxy imaged at the SFU Trotter Observatory processed by Matthew Cimone That star highlighted in the photo is called M31_V1 and resides in the Andromeda Galaxy. The Andromeda – AKA M31- is the closest galaxy to our own Milky Way. But before it was known as a galaxy, it was called the Andromeda Nebula. Before this particular star in Andromeda was studied by Edwin Hubble, namesake of the Hubble Space Telescope, we didn’t actually know if other galaxies even existed. Think about that! As recently as a hundred years ago, we thought the Milky Way might be the ENTIRE Universe. Even then…that’s pretty big. The Milky Way is on the order of 150,000 light years across. A light year is about 10 TRILLION kilometers so even at the speed of light it would take nearly the same length of time to cross the Milky Way as humans have existed on planet Earth. M31_V1 changed all that. This star in Andromeda has the designation “V” because it is known as a cepheid variable. Cepheid variables can be used as a “standard candle” to measure distances across the Universe. We know generally how bright variable stars get. So, if we compare two of them, and one is significantly dimmer than another, we can infer it is farther away in space. In 1924 using this technique, Hubble measured the light of V1 and 35 subsequent variable stars to measure the distance to Andromeda at an incredible 900,000 light years…muc...

At last 80 nearby galaxies are believed to be part of a small cluster called the The three largest members of the Local Group, have their own system of satellite galaxies. Over 50 galaxies are satellite galaxies of the Milky Way Galaxy and are closer to it than the Andromeda Galaxy is. The Andromeda Galaxy is actually number 86 in that list of nearest galaxies. The Small Magellanic Cloud is number 23 and the large Magellanic Cloud is number 19. The nearest galaxy on the list is the If the Canis Major Dwarf Galaxy is not actually a galaxy, the next galaxy on the list would become the nearest galaxy. That is Draco II.

Key Takeaways • Galaxy MCG+01-02-015, located about 293 million light-years away, appears to be a relatively typical, evolved spiral galaxy, with dusty arms and a gas-rich disk. • However, looking at its neighborhood, it's immediately clear that something is amiss: there are no other detectable galaxies to be found within 100 million light-years of it. • Rather than being located along a cosmic filament or on the outskirts of a massive cluster, this galaxy is found in a great cosmic void: the most isolated location of all. The main galaxies of Stephan’s Quintet, as revealed by JWST on July 12, 2022. The galaxy on the left is only about ~15% as distant as the other galaxies, and the background galaxies are many scores of times farther away. And yet, they’re all equally sharp to JWST’s eyes, demonstrating that the Universe is full of stars and galaxies practically everywhere we look. In our own backyard, we inhabit the Local Group of galaxies. This three-dimensional view of the Local Group showcases the three largest galaxies and their relative positions in space: Andromeda (M31), the Milky Way, and Triangulum (M33). Both Andromeda and Triangulum are visible with the naked human eye, as are the Large and Small Magellanic clouds. Over the next few billion years, these galaxies will interact and merge, as our entire Local Group is gravitationally bound. We’re one of many groups on the outskirts of a large galaxy cluster. The various galaxies of our local supercluster, dominate...
