The power needed to create controlled fusion is incredible, so scientists have developed an incredible laser array capable of igniting a miniature star on Earth. The fusion laser system is so powerful that its 411 trillion watts of peak power has an output greater than...
How Galileo contributed to what is known about the solar system
By: Jerry Curtis
Galileo Galilei (1564-1642) contributed to what we know about the solar system in several significant ways: He was the first to use a telescope to systematically observe the heavens. His observations about Earth’s sun, Moon, and stars of the Milky Way lent further credibility...

An asteroid, known as 2012 DA14, is expected to pass close to Earth on February 15, 2013. It has been estimated that 2012 DA14 will be as close as 27,000 km (17,000 miles) from Earth, which is approximately 1/14 the distance of the...

Constellations are the 88 recognized collections of stars with mostly Latin names that occupy a particular section of the celestial sphere. There are some constellations that were named by modern astronomers, although most were derived from classical Greek civilization. The constellations appear almost as pinholes...
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...
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...
