Stars have a dynamic life and are the reason life exists on Earth and perhaps elsewhere. Most are categorized as main sequence stars. There are various types of stars, from brown dwarfs to red giants. The process by which an object entering an extremely strong gravitational field, such as one surrounding a black hole, is stretched vertically and compressed horizontally. Solar wind is a phenomenon that occurs when the heat from the SunвЂ™s corona excites protons, electrons and other particles to a state where they escape the SunвЂ™s gravitational pull. Current scientific theories state that quasars are powered by massive black holes at the center of young galaxies. Quasars are super-luminous objects located at the center of galaxies. PulsarД®xtremely dense neutron stars that rotate extremely fast. The ancient Greeks called these objects вЂњplanetesвЂќ, or wanderers, because their paths across the night sky differed from those of other stars. PlanetД«illions if not trillions of planets exist in our universe, each one unique in its own way. Thousands of protostars may form from certain types of nebulae. Sometimes referred to as molecular clouds, these enormous regions of space consisting of dust, hydrogen, helium, and other gasses. Powerful bursts of Gamma Rays and X-Rays that are fired from the poles of massive stars that are imploding. They come in different shapes and varieties, and are among the most beautiful astronmoical phenomena to be seen. GalaxyД®normous structures in space that are home to millions upon millions of stars and solar systems. There have been a substantial number of exoplanets discovered in the past few years by astronomers, utilizing improved detection methods and telescopes.

Planets located in solar systems and orbiting stars other than our own. Dark matter, to this point, has eluded detection and can not be seen with technologies that known particles and matter can. Scientists believe that small (and possibly exotic) particles account for motions of stars and galaxies that cannot otherwise be explained. Unlocking their secrets helped scientists of the renaissance era to hone and prove their mathematical models.

These вЂњdirty snowballsвЂќ were once believed to be harbingers of doom or fortune. The remnant core or sphere is so densely packed that light and other objects cannot escape its gravitational pull. Black HoleДЄ large, massive star that has run out of fuel and collapsed in on itself. A major вЂbeltвЂ™ of asteroids exists between Mars and Jupiter, and divides the solar system into the terrestrial group of planets and the gasseous giants. AsteroidДЄ broad and diverse group of rocks in space that were little studied by astronomers until the mid-twentieth century. Space phenomena can be defined as naturally occurring events that are caused by the vacuum of space, contained within space or directly result from an event within space. Events in space are among the most intriguing and awesome of all phenomena.
