globular cluster is a spherical collection of stars that orbits a galactic core as a satellite. Globular clusters are very tightly bound by gravity, which gives them their spherical shapes and relatively high stellar densities toward their centers. The name of this category of star cluster is...
blazar (blazing quasi-stellar object) is a very compact quasar (quasi-stellar object) associated with a presumed supermassive black hole at the center of an active, giant elliptical galaxy. Blazars are among the most violent phenomena in the universe and are an important topic in extragalactic...

A succession of distance indicators, which is the distance ladder, is needed for determining distances to other galaxies. The reason is that objects bright enough to be recognized and measured at such distances are so rare that few or none ...

Elliptical galaxies are ellipsoidal agglomerations of stars, which usually do not contain much interstellar matter, and look smoothly like small wads when viewed through a telescope.

Solar astronomy The solar system is subdivided into the inner planets, the asteroid belt, and the outer planets. The inner terrestrial planets consist of Mercury, Venus, Earth, and Mars. The outer gas giant planets are Jupiter, Saturn, Uranus, and Neptune. ...
Many bulges have properties more similar to spiral galaxies than elliptical galaxies. They are often referred to as ”pseudobulges” or ”disky-bulges.” It was first discovered that the stars in some bulges orbit around the galaxy like disk stars. These bulges ... The key properties of disk galaxies, which are also commonly called spiral galaxies, is that they are very thin, rotate rapidly, and often show spiral structure. One of the main challenges to galaxy formation is the great number of thin ...
It is getting to the point where planets are being found everywhere. Fifty here, fifty there,..... After the Big Bang, the universe, for a time, was remarkably homogeneous, as can be observed in the Cosmic Microwave Background or CMB (the fluctuations of which are less than one part in one hundred thousand). There was little-to-no structure ...
The Baby Boom Galaxy is so named because it generates over 4,000 stars per year (compared to an average of just 10 per year for the Milky Way). At that rate, the galaxy needs only 50 million years to grow ...
