It is believed that the universe formed from an event known as the Big Bang. Some 15 billion years ago, a massive clump of matter had seemingly formed from nothing. Theological arguments aside, this ball of gas and dust expanded to the point of exploding...
What earth process creates diamonds
By: Jon Dainty Sr.
Diamonds are one of the hardest materials known to science, making them not only beautiful, but also useful for industrial purposes. They are formed in extreme conditions of heat and pressure from carbon atoms. Coal and diamond creation Some students, it seems, are still taught...

The Kuiper Belt, also known as the Edgeworth-Kuiper Belt, is a region that extends beyond the orbit of the planet Neptune to approximately 50 astronomical units (AU) from the sun. It is composed of small bodies and components from the formation of the solar system...
What is an astronomical unit (AU)
By: Jack Merrywell
An Astronomical Unit, commonly abbreviated “AU,” is a standardized unit of measurement for distances on the order of magnitude of the size of our solar system. 1 AU is equal to the mean distance between the sun and the Earth’s orbit, or...
Overview: The Solar Heliospheric Observatory (SOSO)
By: Andrea Theisson
The Solar and Heliospheric Observatory (SOHO) is an exciting international collaboration between ESA ( European Space Agency) and NASA (National Aeronautics and Space Administration). The SOHO website is very colorful, with easily accessible data, spectacular results, and has many basic science explanatory functions. This project...
