For a long time we have been asking ourselves whether we are alone in the universe. The truth is that we still do not know the answer to this question, however there is a high probability that there are other life forms besides those on Earth. After all, for all we know the universe may be infinite in space-time. Nev... |

The emergence of the human settlements during the Neolithic, 10,000 years ago, created a new biotope. In the new environment, not only domestic animals started to flourish, but also wild fauna that began to depend on human villages - and later cities - for shelter, food, and even security. And not all are useful. For... |

In anticipation of the expected landing of the Phoenix Mars Lander on 25 May, NASA engineers applied a trajectory correction to the flight path. Further modifications to the flight path are expected after the Mars Reconnaissance Orbiter photographs the designated landing area. The Phoenix spacecraft will most likely ... |

The new exo-planet, dubbed GJ 436c, moves in an orbit around the star GJ 436, located in the Leo constellation, 30 light years away from Earth. Relying on the mass of the planet, scientists believe that it could be a rocky planet, about five times heavier than our own. The discovery was made by researchers from the U... |

Why are we so fascinated with the Moon? I mean just look around you, the universe is more than the Earth and its large satellite. Mars, Venus and Mercury are just around the corner, why are we so reluctant at sending a manned mission to any of these planets? The truth is that space missions are extremely dangerous an... |

According to University of North Carolina researchers, the search for extraterrestrial life forms does not necessarily require the find of the actual life forms. Evidence of its existence could be just as rewarding. They reveal that life on Earth could have actually appeared 200 million years earlier than previously ... |

Primitive organic molecules can be found throughout the whole solar system, but they are mostly present in carbonaceous chondrite meteorites. They can also be found amongst the interplanetary dust particles which formed in the early days of the solar system. However, the materials that have the most scientific value ... |

The results of the fly-by made by the Cassini orbiter around Saturn's moon Enceladus reveal that the plume of water vapor above its surface is rich in primitive organic molecules necessary for the appearance and evolution of life as we know it. On 12 March the probe was sent in a fly-by at an altitude of 50 kilo... |

The moon Titan is the largest of all about 60 natural satellites orbiting around Saturn. In fact, it is larger than the smallest planet in the solar system, Mercury.

It's becoming rather clear now that our solar system is not quite as unique in the universe as previously believed. Only 12 years ago we didn't even know if other planets, except those in our solar system, exist in the universe or not, now there are more than 270 other planets that we know about. Extra-terr... |

Images of one of Saturn's moon, brought back by NASA's Cassini orbiter, have recently spawn some of the most fierce debates regarding the solar system exploration program.

No, it's not a fake! Just to clear it out, this image is not some Photoshop creation.

On the other hand, NASA only sees a rock formation ... |

Jupiter's natural satellite Europa, is the only cosmic body in the solar system that might have an ocean of liquid water under its frozen surface, except for Earth.

Well, there is evidence of water on Enceladus' surface but the real question is still whether there are any life forms present there or not.
