Social Networking Site Bebo Wants to Contact Aliens
Social networking sites are the backbone of "Web 2.0" and now one of the most popular sites, Bebo (popular with a younger demographic), hopes to reach out to extraterrestrial civilizations. Why? Well, the power of social networking sites like Bebo, Facebook and MySpace is that you can keep in touch with friends, make new friends [...]

Wind Power From the Ocean (With Help from Space)
I drive regularly through Iowa and southern Minnesota in the US, and over the past few years wind farms have been popping up in that region up almost faster than corn grows. These massive wind turbines are awesome to see. But there may be an even better location for future wind farms than [...]

2012: No Killer Solar Flare
We could be in for a huge firework display in 2012. The Sun will be approaching the peak of its 11-year cycle, called "solar maximum", so we can expect a lot of solar activity. Some predictions put the solar maximum of Solar Cycle 24 even more energetic than the last solar maximum in 2002-2003 (remember [...]

New Instrument Could Reconstruct Planetary and Moon Origins
One of the leading theories for how our Moon formed is the Giant Impactor Theory, which proposes a small planet about the size of Mars struck Earth early in our solar system's formation, ejecting large volumes of heated material from the outer layers of both objects. This formed a disk of orbiting material which eventually [...]

2012: Planet X is not Nibiru
The Solar System's outer reaches still contain many minor planets yet to be discovered. Ever since the search for Planet X began in the early 20th Century, the possibility of a hypothetical planet orbiting the Sun beyond the Kuiper Belt has fuelled many Doomsday theories and speculation that Planet X is actually the Sun's long [...]

How do you Model the Earth's Magnetic Field? Build your own Baby Planet…
The Earth's magnetic field is quite a mystery. How is it generated? How does it remain so stable? We have known of the Earth's magnetic field for hundreds of years and the humble compass has been telling us the direction of magnetic North Pole since the 12th Century. Animals use it for navigation and we [...]

Harvesting Solar Power from Space
In a new report, the viability of sending solar panels into space to collect a vast quantity of uninterrupted energy has been re-investigated. Although the idea has been around since the 1970's, space solar power has always been viewed as prohibitively expensive. In the current energy climate down here on Earth with spiralling oil prices [...]

2012: No Planet X
Apparently, Planet X (a.k.a. Nibiru) was spotted by astronomers in the early 1980's in the outermost reaches of the Solar System. It has been tracked by infrared observatories; seen lurking around in the Kuiper Belt and now it is speeding right toward us and will enter the inner Solar System in 2012. So what does [...]

No Doomsday in 2012
Apparently, the world is going to end on December 21st, 2012. Yes, you read correctly, in some way, shape or form, the Earth (or at least a large portion of humans on the planet) will cease to exist. Stop planning your careers, don't bother buying a house, and be sure to spend the last years [...]

Rising Temperatures Could Shut Down Plate Tectonics
Venus is known as the Earth's twin, but a better name might be Earth's "evil twin" planet. Although Venus has a similar size and mass to Earth, it has a dramatically different surface and atmosphere. And one of the biggest differences is that fact that Earth has plate tectonics, and Venus doesn't. New research indicates [...]

Lightning Storm Generated by Chilean Volcano (Images)
It could be the scene from a movie: huge plumes of ash and gas rising during a ferocious volcanic eruption, sparking off a dazzling lightning storm; lightning bolts thundering to life inside and out of the hot cloud. However, this is the reality down on the ground for the people living near the Chaiten Volcano, [...]

Explore Earth's Ionosphere with Google Earth
The ionosphere is the final layer of atmosphere before space. This highly dynamic region is constantly exposed to the full intensity of the Sun, harsh ultraviolet radiation breaking down molecules and atoms. Highly charged ions and free electrons therefore fill the ionospheric layers. Critical to terrestrial communications, the ionosphere also plays host to the largest [...]

Gaia Hypothesis: Could Earth Really be a Single Organism?
Can a planet like Earth be considered a single living organism? After all, the human body is composed of hundreds of billions of bacteria, and yet we consider the human body to be a single organism. The Gaia Hypothesis (or popularly known as "Gaia Theory") goes beyond the individual organisms living on Earth, it encompasses [...]

Potential Global Warming "Fix" Will Damage the Ozone Layer
There are many possible "geo-engineering" solutions open to scientists in the aim to stave off global warming. One of the main candidates to dim the solar energy input to the atmosphere is to inject huge quantities of sulphate particles high in the atmosphere. This mimics the emissions from a large volcanic explosion proven to cool [...]

Apollo 8 Astronaut Bill Anders Reflects on Earthrise Picture
In December of 1968, the Apollo 8 capsule had successfully gone into orbit around the moon and the crew was busy taking pictures of the lunar surface. On the third orbit, as the Apollo capsule was coming around from behind the moon, commander Frank Borman lookup up and called out, “Wow! Look at that!” [...]
