Exoplanets are planets outside of the solar system. Since the first extrasolar planet was detected in 1992, astronomers have detected nearly 1,000 exoplanets orbiting other stars. The search for new exoplanets continues, as scientists try to determine whether there may be truly Earth-like planets...
Interesting facts about the Andromeda galaxy
By: Jose Juan Gutierrez
The Andromeda Galaxy (M31/ NGC 224) is a spiral galaxy, lying in the Andromeda constellation, 2.5 million light-years from Earth. The Andromeda Galaxy is the most prominent galaxy in the local group, containing twice the number of stars of those in the Milky Way...

Cosmic rays, or extremely high-energy particles originating from sources outside of the solar system, reach Earth on a regular basis. Typically, they collide with atoms in the atmosphere to produce dramatic sprays or "showers" of lower-energy particle debris. These showers can be detected by sensitive...
The origins of cosmic rays
By: Jose Juan Gutierrez
Cosmic rays are very high energetic particles of which 99% are made of the nuclei of atoms. Cosmic rays originate outside of the solar system and when reaching the Earth's atmosphere produce an array of secondary particles that strike the Earth in all directions. The...

White dwarf planets are planets which orbit white dwarfs - the glowing remains of dead stars which used to be roughly the size and brightness of Earth's own Sun. In recent years astronomers have grown interested in white dwarf planets because it is easier to...
