The idea of solar cells is so cool! They would come with such cheap energy, and everybody would be a Captain Planet fighting pollution. But what many people still do not understand is that they are so inefficient at this moment. A new research published in "Applied Physics Letters" could come with a step further to t... |

Wireless mice are all too common nowadays in a computing environment that is more and more centered on mobility. The main drawback of most such wireless mice is that after a few days at most the batteries must be changed, or if rechargeable units are used they must be left several hours to replenish their energy leve... |

It's a common sight in numerous science fiction stories and movies: a planet with two suns (often of drastically different colors) producing double shadows, multiple sunrises and sunsets and other exotic phenomena that would appear utterly alien to us Earthlings, like Luke Skywalker's home planet, Tatooine... |

Some people are more aware than others when it comes to protecting the environment. While some of them think that by not dumping trash wherever they are at the moment is a huge environmental act, others are building entirely self-sufficient houses that take everything from nature without hurting it.When it comes to ... |

Harvesting solar energy is a clever way to make use of a clean and renewable fuel. You don't need to dig the ground for it, there are no pipes and powerplants, and best of all, it's ecological. Unfortunately, existent solar cells are not too efficient and often too expensive.A new development made by resea... |

This comet is one of the few that really spawned some controversy regarding the possibility of a collision with Earth and was even classified as having "a non-zero possibility of impact." This means it could hit our planet or the Moon, sometime around 3044, or at least that is what astronomers thought about four dec... |

Have you ever looked at the sky at night and found the famous band of stars called the Milky Way? Probably, but did you notice it's tilted at an angle? Well, this thing really puzzled astronomers for quite some time.That's because what you saw is actually our galaxy itself, seen from the side. The classica... |

Samba and Tango are the names of two of ESA's four satellites in the Cluster mission that are now orbiting in formation, separated by only 17 km, the closest two ESA satellites have ever been. It is hoped that this tight formation will allow new scientific discoveries about the Sun and the solar wind.The Cluste... |

Pluto is the ninth planet of our solar system, the smallest and the farthest. No, wait, it's not a planet anymore. Trouble never seems to end for this little fellow, after the "embarrassment" of being degraded to a lower rank.The former planet has been dissed again. As it turns out, it's not even the bigge... |

Yesterday, two of the astronauts on board the International Space Station floated outside to work on the retraction of the starboard solar array. They helped fold up an old solar wing and to resurrect a rotating joint that will make the new pair of solar arrays follow the Sun.Last week, two Russian cosmonauts on bo... |

A mystery about the interior of the Sun lasting for centuries has been solved by scientists at National Science Foundation (NSF) and NASA. They now proved that sound waves escape the interior of the sun and form fountains of hot gas that shape and provide fuel for a region of the sun's atmosphere.This thin regi... |

It may sound strange, but it seems some planets are ejected from the solar system where they were born, while still in an early development stage, and set to wander the interstellar space. That's kind of a scary thought, even though actual pictures of such planets may look good.Remember the sci-fi series of the... |

Most astronomers believe that our solar system formed from the gravitational collapse of a giant molecular cloud, which was likely several light-years across and probably birthed several stars. But a new find contradicts that nebular hypothesis, saying it wasn't a black hole that gave birth to the Sun and the p... |

Photovoltaic cells, as the word implies (photo = light, voltaic = electricity), convert sunlight directly into electricity. Once used almost exclusively in space, photovoltaics are used more and more in less exotic ways. They could even power your house, but they are more widely used for satellites and spacecrafts, ... |

The sun is an incredible ball of energy that provides a free, renewable resource in the form of heat and light. Just 20 days of sunshine produces the same amount of energy as all of Earth's reserves of oil, coal and natural gas. Solar energy can be harnessed passively through appropriate design principles as we... |
