We actually don’t know that many things about stars, despite the fact that there have been many attempts and numerous researches in the field. The only close star we have most access to, theoretically speaking, is the Sun. But we only know little about it as well, given the still limited technology we have, and... |

Supermassive black holes, with a mass approximately a billion times that of our Sun, have been thought to reside at the very heart of the biggest galaxies, including our own. A recent computer simulation, corroborated with data obtained from the Chandra X-Ray Observatory, indicated that one of these black holes gener... |

An innovative technique, devised by Geoplasma (GP), an Atlanta-based company, will be used to power up some 50,000 homes in Florida. The new technology could have been a part of a SF movie just a few years ago, as it incorporates plasma beams to vaporize the trash. But GP officials say that their new processing unit ... |

It would really seem that, these days, LG's going mostly for those people who appreciate both style and high-end features in their HDTVs. After they've announced the very elegant Scarlet a while back, the Korean company is now back with two PDPs (plasma displays), the PG3000 and PG200R models, which have a ... |

Plasma has two main components, the positive and the negative clouds of gas mixed in different proportions. Neutral plasma containing equal amounts of positive and negative charges is called strongly-coupled plasma and occurs naturally on the surface of neutron stars, the cores of gas giants and may have even been th... |

The newly discovered glowing feature in Jupiter's atmosphere seems to be produced by a stream of electrically charged particles rushing from the planet's small volcanic moon Io, much in the same way the solar wind determines the appearance of aurora borealis on Earth in the polar region of the planet. Accor... |

When saying lightning, only one thing comes immediately to our mind, namely the image of a roughly linear electrical discharge through the Earth's atmosphere. This doesn't mean however that this is the one and only definition of a lightning. There is evidence, for example, that lightning discharges can take... |

A survey conveyed online by a firm selling televisions was released on Friday and the results are rather surprising. Almost half of the UK men would gladly give up 6 months worth of sex for the 50-inch plasma TV. Hoping that it is just a sample of typical British conservationism when talking about private life and mo... |

What do you see when you look upwards on a clear sky night? A few thousands stars maybe, some of the planets in the solar system, and the Moon... Looks kind of empty, doesn't it? The fact is that our galaxy is mostly cold empty space, as much as the universe. Nonetheless, astronomers from the Paul Scherrer Insti... |

It is a well known fact that Saturn's ring E is interacting with the moon Enceladus, and might have been created by drawing material ejected through cryo-volcanism phenomenons taking place of the surface of the moon. However, new observations conducted by NASA's Cassini orbiter reveal that icy plumes of mat... |

Because plasma is mostly composed of charged particles, such as electrons and ions, which have a global neutral charge, it is able to generate powerful magnetic fields, a very important feature if you ask a nuclear physicist working on the design of a nuclear fusion reactor. However, all good things must also have ba... |

The conventional incandescent light bulbs use electrical current that passes through a thin filament, heating it and causing it to become excited, releasing thermally equilibrated photons in the process. The problem is that only 2 percent of the released energy takes the form of light and the remaining 98 percent is... |

Pneumatic tires or tyres are used on all types of vehicles, from cars to earthmovers to airplanes. A significant disadvantage of tyres is the fact that recycling them is not very easy and so mountains on tyres are gathering all across the world.It may come as a surprise, but the same technique that makes tyres so du... |

The basic idea of a plasma display is to illuminate tiny colored fluorescent lights to form an image. Each pixel (the tiny dots on the display) is made up of three fluorescent lights - a red light, a green light and a blue light - which are evenly distributed on the screen. By combining these colors in different prop... |

Plasma is a very hot, ionized gas that conducts electricity and has a main role in the fabric of stars. The principle is simple: if we heat hydrogen ions to the point of ignition, they could fuse into helium and this fusion could be a clean, sustainable and endless energy source. And if the Sun does it, converting 40... |
