Recent astronomical observations seem to point at the fact that the Milky Way, our own galaxy, is currently colliding with a dark, high-velocity cloud of hydrogen gas, known as Smith's Cloud. The formation may be a galaxy in itself, according to the most recent hypothesis, and not a common one. In fact, astronom... |

Ithaca, NY-based Widetronix is currently developing a new generation of nuclear batteries, called betavoltaics. The devices are able to produce a steady flow of low current levels, and can last for up to 25 years, experts say. The batteries will soon undergo their testing phase, and the entire process will be supervi... |

For many decades, the basic principles of producing rocket fuel have remained the same. Boosters are still fueled by mixtures of liquid hydrogen and liquid oxygen, chemicals that burn hot and fast enough to provide the massive thrust force several tens of tons of metal require to be lifted off the ground. This year, ... |

For a very long time, researchers have tried, unsuccessfully, to turn hydrogen into metal. This is known to be possible, and, probably, this form of the chemical is present on other planets, most likely gas giants, but it's impossible to obtain the material here on Earth. It has tremendously large pressure requi... |

Hydrogen-based vehicles are, at this point, a fairly uncommon occurrence, mostly because the designs are still plagued by engineering and technical issues. One of these problems is how to recycle hydrogen-containing fuel materials, so that they can be used again. Scientists from the Los Alamos National Laboratory (LA... |

In a test that took place yesterday, July 1st, at the Kennedy Space Center's Launch Pad 39A, space shuttle Endeavor's external hydrogen fuel tanks were filled to the brink with propellant, as engineers watched the troublesome valve that kept the shuttle from taking off twice with tension. But, after adding ... |

Lyman-alpha blobs (LAB) are, quite simply put, the largest things in the Universe. They dwarf galaxies, and, when they were first discovered about a decade ago, seemed to only exist to annoy astronomers. Made entirely out of hydrogen gas, the blobs also glow, a feat that has had astrophysicists thinking for years. No... |

Experts have known for a very long time that water is a very peculiar liquid. Its anomalies allow for it to move in nature the way it does, and also to allow a host of other biological processes, including the little thing called life, take place. Its properties are still puzzling to physicists and chemists, as they ... |

Hydrogen is, at this point, the leading source of alternative fuel in the world. Its potential to power up the cars and vehicles of tomorrow is only limited by the fact that there are currently no materials able to hold vast amounts of hydrogen. This is necessary for giving the vehicles a range similar to that they h... |
