The Andromeda galaxy is our closest spiral. 1. It was once classed as a nebula Before the true scale of the universe was realised, what is now known to be the rim of our own Milky Way was thought to be the edge of space. Within that the Andromeda galaxy (M31), little more than a fuzzy blur in the sky to all but the most powerful telescopes of ...
Jun 8, 2015 · Although the Milky Way is probably the most massive in the galactic Local Group, Andromeda is the biggest by volume. Our neighbouring galaxy also contains around twice the number of stars as our own galaxy, according to observations made by the Spitzer Space Telescope. Dozens of black holes lie here. The centre of M31 is home to 26 known black ...
Mar 18, 2021 · If there is life in the andromeda, there isn't proof since we are looking at it in the past, when infact there could be life there in the present. If that is true, all other sentient and conscious life could be thinking the same about us. Also just to ramble on a little bit more, if the multiverse theory were plausible, wouldn't it likely be ...

Galaxies are not really living objects, so while they can’t die, they can in fact change. The galaxies we see in the night sky have been around for billions of years and remain unchanged for millions of years. However they do evolve and they can also be disrupted by the gravity from other galaxies. In fact, our own Milky Way is on a collision ...
Feb 2, 2018 · Now that three galaxies have been observed – the Milky Way, Andromeda and now Centaurus A – for this to be a coincidence is highly unlikely. The standard model of cosmology cannot explain why how these similar orbits arise around a superior galaxy, but they do strength the theory that dwarf galaxies form during the collision of two larger galaxies.
Elliptical galaxies are generally featureless to look at with an ellipsoidal shape and a brightness that is concentrated at the centre which fades away the further from its core you move. Galaxy groupings like the Virgo Cluster are common in the sense that elliptical galaxies can be found at their centre. Keep up to date with the latest reviews ...
Nov 8, 2018 · The Hubble and Keck Observatory images captured close-up views of this final stage, when the bulked-up black holes are only about 3,000 light years apart — a near-embrace in cosmic terms. The dusty cores of these merging galaxies is the slow dance of their supermassive black holes toward an eventual union.
Sep 21, 2023 · Astrophysicists have discovered that the velocity of stars orbiting (let’s say the center of gravity of the Andromeda galaxy) does not decline as the inverse square of the distance from the center of gravity of the Andromeda galaxy and that the stars orbiting around Andromeda galaxy have reached escape velocity because of insufficient visible mass to hold the high velocity stars in orbit ...
She began her research with our closest spiral, the Andromeda galaxy. Luckily, her theory was greeted with open minds as well as prestigious awards. Rubin believed that since galaxies are rotating so fast, the gravity that holds the stars together alone wouldn’t be enough to stop the structure from flying apart.
