The differentiation between the types of galaxies was thought to have been the result of initial conditions. If lots of angular momentum were present, a disk galaxy was produced. If initially there was little angular momentum, all matter became stars during the collapse phase, resulting in an ...
variousOn the basis of the Hyper - Leda Catalogue (HyperLeda) 8293 galaxies with heliocentric radial velocities below 2500 kms~(-1) were selected; 4570 had known morphological types (4366 had calculated b/a ratio). We checked the frequency of the distribution of various types in the LSC, ...
of the night sky consists of about hundreds of billions of stars in our galaxy.Our galaxy is a spiral (螺旋式的) one,but there are other types.∠ASPIRAL GALAXIES:There are galaxies that have spiral arms that appear from the center.Our solar system is located on one of the arms of the...
These real-life objects are scattered throughout theuniverse, particularly at the centers of galaxies. So, they're common, but nobody hasreally explored them. There's a good reason for that: once you get inside a black hole,there's no escape.That makes them interesting and frightening all...
