Everyone who has ever wiped out dust from an entire house can tell you that, just hours after cleaning, the stuff always returns undisturbed, as if nothing ever happened. This is naturally a nuisance to people who spend hours trying to clean up. Most of us have also wondered as to where all the dust keeps coming from... |

Gathering and studying cometary dust is arguably one of the most difficult enterprises today, as the technology to do so is still some years away. But, in 2003, the proverbial mountain came to the scientists, in the form of an Earth-crossing comet that left behind a trail of material that got experts excited. High-fl... |

Many experts currently consider that Mars' reddish hue is owed to rusted rocks, which were subjected to the action of the water that once covered the planet. This idea has been proposed and debated for a long time, but recent laboratory studies are beginning to infirm it, some experts say. The investigations hav... |

According to an Australian researcher, there is a very tight connection between the amounts of dust that are in the lunar atmosphere at each given point and the time of the day when dust readings are recorded. He says that, when astronauts in the 1960s and the 1970s walked on the Moon, it was in the early hours of th... |

The Orion Nebula is, perhaps, one of the most scrutinized objects in the sky, mainly because it can be seen with the naked eye during bright nights. Located in the Orion Constellation, some 1,270 light-years away from Earth, the giant formation has been recently proven to be the stage for the formation of countless n... |

For quite some time now, climatologists have known that the layers found in most ancient ice shelves and in large icebergs can be used to get a glimpse into our planet's ancient history, at least as far as climate changes go. Each layer is specific to a certain period of time in our planet's past, and each ... |

Over the last decades, our solar system has been experiencing a massive sand storm, not unlike those that can be found in the desert. All the planets orbited the Sun in a halo of sand particles that is now considerably larger than it was a century ago. The reason for these large amounts of cosmic debris has kept astr... |

There seems to be a constant rush as of late to demonstrate that what we used to know and treat as a given is wrong. Evolving technology and the increased amount of accurate scientific data provide more insight on many of these aspects that were not thoroughly investigated so far. As such, it appears that the prevale... |

Possibly, Drake's equation should also take into account the factor of comet activity in the environment of the planets that could actually support life. New statistics suggest that our own solar system is far more spared by such cosmic catastrophes than the similar nearby ones, so we own our very existence, to ... |

As described in a previous article, Moon dust is a terrible problem that astronauts have to face and which has to be solved if humans are ever supposed to set a firm foot on lunar surface for more than just an erratic scientific expedition. That type of dust is extremely fine and rugged, as well as very adherent to a... |

It is generally believed that supernovae usually spread dust into interstellar space as they explode. However, astrophysicists have recently found that this is not always the case, and some might actually collect dust after a supernova phase. These are usually small stars that explode periodically, while gathering cl... |
