The term almost exclusively refers to the central group of stars found in most spiral galaxies (see galactic spheroid). Bulges were historically thought to be elliptical galaxies that happened … Meer weergeven Bulges that have properties similar to those of elliptical galaxies are often called "classical bulges" due to their similarity to the historic view of bulges. These bulges are composed primarily of stars that are older, Meer weergeven Most bulges and pseudo-bulges are thought to host a central relativistic compact mass, which is traditionally assumed to be a supermassive black hole. Such black holes by definition cannot be observed directly (light cannot escape them), but … Meer weergeven Many bulges have properties more similar to those of the central regions of spiral galaxies than elliptical galaxies. They are often … Meer weergeven • Disc galaxy – Type of galactic form • Galactic coordinate system – Celestial coordinate system in spherical coordinates, … Meer weergeven
Astronomy: Is over-eating to blame for bulges in Milky Way bar?
WebThe bulge stars, most of which are more than 10 billion years old, have unusually high amounts of heavy elements, presumably because there were many massive first-generation stars in this dense region, and these quickly seeded the next generations of stars with heavier elements. 25.6 The Formation of the Galaxy Web6 nov. 2015 · NGC 4565 is what the Milky Way might look like from the outside, its "boxy," Twinkie-like bulge surrounded by a spiral disk.
