Is mining the asteroids possible?
By: Toni Macdonald
Is mining the asteroids possible? The short answer is no. While it seems perfectly feasible, it is not possible at this moment due to a number of conflicting factors. These factors guarantee the impossibility of mining the asteroids at the present time, but include a...

According to the European Space Agency (ESA) one of the most dangerous, toxic substances on Earth, nuclear waste, may become the future fuel for interplanetary freighters and space luxury liners.What to do with nuclear waste has been the subject of spirited debates since the...
The speed of light explained
By: Jose Juan Gutierrez
The speed of light in a vacuum, like that of the outer space, travels at 299,792,458 meters (186,282 miles) per second. In physics the speed of light is denoted as c, and is the greatest speed at which all matter and energy...

The role of spectroscopy in astronomy
By: Jose Juan Gutierrez
Astronomical spectroscopy is one branch of spectroscopy that deals with the physical and chemical properties of astronomical objects. It is a technique that measures the absorbed, emitted or scattered light of materials. Spectroscopy´s role in astronomy involves the determination of a variety of stellar...

Relationship between wavelength and frequency
By: Jose Juan Gutierrez
Light and other forms of energy, including sound, are measured by its wavelength and frequency. Wavelength multiplied by frequency is equal to the speed of light. The relationship between wavelength and frequency is that they are inversely proportional to one another. That is to say...
