Telescopes may not be able to view all the stars in a galaxy, however. A 2008 estimate by the Sloan Digital Sky Survey (which catalogs all the observable objects in a third of the sky) found about ...


Of course, this is just a tiny list of stars. There are some enormous lists of stars out there. One of the most comprehensive is the SIMBAD database. This is an online database that contains 4.3 ...


So how many stars are there in the Universe? It is easy to ask this question, but difficult for scientists to give a fair answer! Stars are not scattered randomly through space, they are gathered together into vast groups known as galaxies. The Sun belongs to a galaxy called the Milky Way.


These luminous balls of gas helped ancient explorers navigate the seas and now help modern-day scientists navigate the universe. ... their temperatures are not all the same. Hot stars appear white ...


Planets in our Universe can get extremely large, but stars get even bigger. In this video we explore the sizes of moons, planets, stars, and even beyond, including black holes and even galaxies.


Unlike most stars, which occur in either binary or multiple star systems, VY CMa is a single star. It is categorized as a semiregular variable and has an estimated period of 6,275,081 days, or ...


Universe galaxies and stars is a website designed to help people think about all space and cosmos related issues, from the Big Bang Theory to the end of Time. The universe is packed with galaxies and stars. The universe is often called space, and is sometimes known as the cosmos. It is believed the universe was created by the big bang theory.

The observable universe is a spherical region of the Universe comprising all matter that can be observed from Earth or its space-based telescopes and exploratory probes at the present time, because electromagnetic radiation from these objects has had time to reach the Solar System and Earth since the beginning of the cosmological expansion.


Below is an ordered list of the largest stars currently known by radius.The unit of measurement used is the radius of the Sun (approximately 695,700 km; 432,288 mi).. The exact order of this list is very incomplete, as great uncertainties currently remain, especially when deriving various important parameters used in calculations, such as stellar luminosity and effective temperature.
