How Does Accretion Start? In astrophysics, accretion is the accumulation of particles into a massive object by gravitationally attracting more matter, typically gaseous matter, in an accretion disk. Most astronomical objects, such as galaxies, stars, and planets, are formed by accretion processes. Where and how does accretion happen? Accretion is the process in which material
Is The COBE Still In Space? COBE’s Diffuse Infrared Background Experiment measured radiation from the formation of the earliest galaxies. After four years of observations, the COBE mission was ended, but the satellite remained in orbit. Where is COBE? The COBE was launched from Vandenberg Air Force Base in Lompoc, California at dawn on November
Is The Galaxy Infinite? Space spreads out infinitely in all directions. Furthermore, galaxies fill all of the space through-out the entire infinite universe. … This means that the universe does not wrap around and connect to itself like the surface of a sphere, which would lead to a finite universe. Does the Galaxy go on
Is The Universe Shaped Like A Person? The universe is similar to a huge human brain, scientists have found. A new study investigated the differences and similarities between two of the most complex systems in existence, though at entirely difference scales: the cosmos and its galaxies and the brain and its neuronal cells. How does
How Do Quasars Die? A quasar dies when it runs out of material falling into the accretion disc. How long do quasars last for? Quasar emission can only last as long as there is fuel available to form an accretion disk. Quasars can consume up to 1000-2000 solar masses of material per year, and have
Is The Large Magellanic Cloud A Spiral Galaxy? The LMC is classified as a Magellanic spiral. It contains a stellar bar that is geometrically off center, suggesting that it was a barred dwarf spiral galaxy before its spiral arms were disrupted, likely by tidal interactions from the Small Magellanic Cloud (SMC) and the Milky Way’s
Is Gargantua A Real Black Hole? Gargantua is a very massive, rapidly spinning black hole. … A main sequence star Pantagruel was located within a year’s flight of Gargantua along with the habitable planet Edmunds. Gargantua is within a several week spaceflight of the Wormhole. Is Gargantua a quasar? The swirling yellow ring of super-hot
Is The Sun Revolving? Yes, the Sun does spin, or rotate. Because it is a gas, it does not rotate like a solid. The Sun actually spins faster at its equator than at its poles. The Sun rotates once every 24 days at its equator, but only once every 35 near its poles. Why is
Is The Milky Way A Spiral Or Elliptical Galaxy? They come in a variety of shapes and sizes. The Milky Way is a large barred spiral galaxy. All the stars we see in the night sky are in our own Milky Way Galaxy. What type of galaxy is the Milky Way? The Milky Way is
Is The Milky Way Expanding Or Contracting? The Milky Way, the galaxy which contains our own solar system, is expanding and will eventually grow into its neighbour, Andromeda. Already 100,000 light years in diameter, new research puts its rate of growth at about 500 metres per second. Why is the Milky Way not expanding? The
