these galaxies are either range from having a spherical to egg-like shape. In some regards they look similar to large star clusters, however, the presence of large amounts of dark matter help distinguish them from their smaller counterparts. ...

1.3. In the following sections, we will pass through the individual sites from the Big Bang to stars, stellar evolution, and stellar explosions in single and binary systems, before returning at the end to the understanding of the evolution of galaxies with the knowledge of the previous sections...

There have been two main types of galaxy formation models to explain all those observations. The first asserts that massive elliptical galaxies formed in a single, rapid collapse of gas and dark matter, during which virtually all the gas was turned quickly into stars. Afterward the galaxies chang...

The stars within them are predominantly old (spectral types K and M).Galaxies with a second, disk-shaped component in addition to the bulge are known as spiral galaxies. They form flattened systems containing prominent spiral arms of interstellar matter and bright young stars that wind outward ...
GALAXIES (星系) OF THE UNIVERSE The Milky Way is only one galaxy among a few hundred million galaxies in our universe (each with hundreds of billions of stars).Galaxies are huge groupings of stars, planets, gas and dust. Our sun is in the Milky Way, which measures about 100,000 light...

The broad variation in possible formation histories and the wide range of cosmic environments make large statistical samples of galaxies essential for identifying the important physical mechanisms that govern their formation. Starting in the early 2020s, the Large Synoptic Survey Telescope (LSST) will ...
