Since all our insights and discoveries in science naturally lend themselves to mathematics, it is interesting to learn that we have no simple guide for correlating mathematical symbols with concepts of ordinary language. What we want to point out here is the inherent limitations of...
How the constellations got their names
By: Effie Moore Salem
Constellations are groups of stars close together that appear to form shapes. When discovered they were given names suggestive of their shapes. It takes keen eyes indeed to see what they saw and not everyone is that adept. But that didn’t stop ancient astronomers...
How Galileo contributed to what is known about the solar system
By: Richard Hogsflesh
Galileo Galilei (1564-1642) made many advances in mathematics and physics, but is best remembered for his contributions to astronomy. He was central to challenging the idea that the Earth sat at the center of the universe with everything revolving around it (the ‘Ptolemaic system&rsquo...
How Galileo contributed to what is known about the solar system
By: Steven Bishop
Much of the early scientific discoveries made about our solar system came from the great Italian mathematician Galileo Galilei. This extraordinary figure in the history of astronomy and physics played a vital role in the understanding we currently have of the cosmos, and particularly own...

The two newest editions to the periodic table are Flerovium, and Livermorium, which were both first synthesized over ten years ago. Only now have these new elements been accepted by the IUPAC, which is the International Union of Pure and Applied Chemistry. As of June...
How the Pathfinder spacecraft differs from the Viking
By: Patrick Sills
The Viking and Pathfinder were two different names given to unmanned spacecraft launched from the United States that landed on the planet Mars and gathered data. Approximately two decades separated the Viking and Pathfinder missions. The Viking Program took place in the 1970s, while the...

The Viking program was a precursor to many Mars landing missions. It used the combination of an orbiting satellite and a lander to gather data about the conditions on Mars. The Pathfinder was a later Mars landing project. Using knowledge from the Vikings, NASA was...

The differences between refracting and reflecting telescopes are quite simple. A refractor style telescope is the defacto design of spotting scopes and solar telescopes, as well as for planetary and bright object viewing. A refractor is a very simple design. The light is focused through...
Asteroid facts: 2012 DA14
By: Steven Mars
The asteroid 2012 DA14 was sighted February 2012 when Granada, Spain astronomers in La Sagra Sky Survey Observatory were searching areas where asteroids had not usually been seen. Since it will be only 14,913 miles from the Earth (24000 kilometers) February 15, 2013, it...

The Earth's magnetic field (magnetosphere) is a gigantic invisible shield surrounding the Earth, which protects the planet from solar radiation. The invisible forces extend from the Earth;s poles for thousands of kilometers into space (magnetosphere). The Earth's magnetic field is generated in the interior...
