Characteristics of Galaxies Galaxies tend to have the following characteristics: Galaxies range in their numbers of stars from smaller galaxies with just a few hundred million stars to massive galaxies with trillions of stars. Almost all galaxies contain asupermassive black holeat their centers; this ...

Stars and their exoplanets evolve together. Depending on the physical characteristics of these systems, such as age, orbital distance and activity of the host stars, certain types of star-exoplanet interactions can dominate during given phases of the evolution. Identifying observable signatures of ...
Classifying dreams is part of dream interpretation. The types of dreams people analyze vary as much as the symbol base they use for analysis. Some people also seek to understand why we dream the types of dreams we experience. The search for answers involves considering environmental, physical, ...
Thus far, we've talked about how spiral galaxies develop and how rotation shapes their arms. But what's the deal with those bulges we mentioned earlier? At the center of spiral galaxies, you'll find a cluster of very old stars revolving around a central point. This is the bulge. While...

Their appearance ranges from circular to very stretched out. Elliptical galaxies have less dust than their spiral counterparts, and so the star-making process has all but ended. Most of their stars are older. Although they make up a smaller portion of the visible galaxies, astronomers think ...

A spiral galaxy is a classification given to a massive grouping of stars, space dust, and gas. Spiral galaxies are so named because of their visible and notable arms that wrap around the disk (center) of the galaxy. What are the 3 major galaxy types? There are three main types of galax...
