They are out there, we know what kind of destruction their capable of, however we have also been lucky enough not have such an object forming in the vicinity of our solar system. Or haven't we? Our biggest threat right now, however, doesn't come from black holes, death rays of any kind or other impending di... |

Jupiter and Earth, two extremely different planets. One has a solid surface, the other has no surface at all; one is a rocky planet, the other, a massive gas giant, and so on. However, this doesn't mean that the two are totally different from one another. It looks like Jupiter and the Earth share one key feature... |

It would certainly appear so, and considering that our galaxy is filled with at least 200 billion stars, it would be no surprise if one of these rays of death would decide to hit our planet some day. However, the subject of discussion here is a star dubbed WR104, located about 8,000 light years from Earth in the Sagi... |

Following the steps of their fellow colleagues form the European Space Agency, NASA also has in plan to implement a program to predict the space weather determined by the activity of the closest star to Earth - the Sun. Lying just over 150 million kilometer from Earth, the Sun, with a diameter about 100 times that of... |

How would we know when the winter comes, if it weren't for the seasons on Earth? One might say, well if there aren't any seasons, why would we even want to know such information? Let's say its kind of a mental exercise. The best way of finding out what season the Earth is in is by tracking the motion o... |

You got the point, apparently the Earth has more than one North Pole! I'll put it like this: the North Pole can be anywhere you want it to be. It could be in Alaska, in the town called 'North Pole' for what I'm concerned, but then we would be deviating away from the story. For starters, there is t... |

There are possibly millions of Earth-like planets lying out there in the immensity of the universe, each bearing just the proper conditions for the appearance and evolution of life, we just have to find them. Only a decade ago or so, the human race wasn't even capable of telling whether nearby stars, or any star... |

The European Space Agency's Venus Monitoring Camera, or VMC for short, surprised in the summer of last year what seems to be a bright haze that appeared and disappeared in Venus' atmosphere in a time interval of only a few days. The region where the feature was observed by the VMC is located near the southe... |

Our large Moon is a testimony to the fact that Earth could have been created during a collision between two massive protoplanetary bodies. Could Venus have been created in the same way? Cardiff University scientist Dr Huw Davies believes so. This would be a first step into explaining why Venus, though relatively simi... |

A pretty small prize, one would say, especially considering the implications of a large asteroid hitting the Earth in the near future. We may at least stay calm until the day of 13. April 2036, that is. This is the date when the largest asteroid orbiting through the close vicinity of the Earth may execute a fly-by ar... |

If you have missed it, you will have to wait for the next one until 2010.

Divine intervention versus random processes in the universe and the question why. Why are we here, why does the universe exist and, mostly, why is it the way we see it today?

Earth, like all planets in the solar system, has an inner most core, in the shape of a sphere measuring about 1,200 kilometers, consisting of a solid mass of iron, responsible for generating our planet's powerful magnetic field. Nonetheless, while implying measurements of its structure with the help of seismic w... |

We've actually come to know more about the 2007 WD 5 asteroid than about that other big hunk of rock that passed near Earth about two days ago.

Yesterday, the asteroid 2007 TU 24 passed through the vicinity of our planet at a distance of only one and a half times further than the distance to the Moon, while today 2007 WD5 will make a fly-by around the planet Mars at a distance of only 26,000 kilometers. Oh... you might have noticed how both asteroid's n... |

The Earth's mantle can stretch up to 2,900 kilometers below the surface, thus the only way to study it is to conduct measurements on the speed of seismic waves which travel through it, in order to determine the rough composition and density.

All of a sudden, it started raining with asteroids!

Because they are so small in size, many less than 150 meters in diameter, astronome... |
