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...

“We’re on Mars again.” These simple yet astonishing words were spoken by NASA chief Charles Bolden as the Curiosity rover touched down on the Red Planet one year ago this week. The one tonne mechanical marvel had survived a nine month journey...
An overview about the chemical element Polonium
By: Kenzie Knox
Polonium (Po) is a rare element with atomic number 84 located in the p-block of the periodic table. Polonium has 33 known isotopes, all of which are radioactive. This element was discovered by Marie and Pierre Curie in the late nineteenth century. Polonium-210 is the...
