If an asteroid hits the Red Planet, it could be the second time in history when humanity witnesses a collision between a celestial body and a planet in the solar system, other than the Earth, since the event in 2004 when the broken comet Shoemaker-Levy 9 intersected the orbit of Jupiter, creating giant fireballs in i... |

When it comes to asteroids size really doesn't mater, as they can hit Earth's atmosphere with forces similar to those of bigger cousins. This information is even more baffling when you take into consideration that in our effort to detect the biggest threats posed by asteroids to Earth we have been unable to... |

This year, the Geminid Meteor Shower will peak on the night of 13-14 December, and is thought to make quite a show on the night sky, or as astronomers David Levy and Stephen Edberg would say, 'if you haven't seen a Geminid fireball, then you haven't seen a meteor'. This particular meteor shower ge... |

Everything is fine on planet Earth. Well... not really. Not only that we commit suicide every day, by dumping enormous quantities of green house effect gases into our atmosphere, amongst other several problems, but we have no clear viable plan to handle the threat posed by the asteroid in the vicinity of our planet, ... |

The planets and the moons in the solar system often get pounded by differently sized objects, creating large cracks and craters on their surface. These energetic impacts are often due to the moon's regular motion and spinning. To better understand the effect that these events have on the motion of a planet or mo... |

Last weekend, the Minor Planet Center announced they detected a Near Earth Object that would miss the Earth only by 5,600 kilometers. The newly discovered object, has been given an official name by the MPC, run by Smithsonian Astrophysical Observatory. 2007 VN84 was tracked by a number of astronomers around the world... |

Remember the asteroid that killed the dinosaurs and almost wiped all life from the face of the Earth? NASA says there is no immediate risk of that happening in the near future, although there might be a lot of such objects in the near vicinity of our planet that could intersect Earth's orbit and cause havoc, wh... |

On June 30, 1908, the biggest space impact that Earth suffered in modern times, known as the Tunguska event, took place in a remote Siberian area, destroying more than 2,000 sq km (770 square mi) of forest near the Tunguska River (central Siberia). The ball of fire that could have been a comet or asteroid, blasted a... |

A solution reminding us of the "Armageddon" movie and high-skilled drillers like Bruce Willis would help only as plan B. In fact, scientists are focusing on flying mirrors to save the Earth from a catastrophic asteroid collision. No less than 5,000 mirrors would be necessary to focus a sunlight fascicle on to the ast... |

Some people sustain that our oceans came from space, brought by water-filled asteroids and comets showering on a juvenile Earth, 3.8 billion years ago. But this concept is challenged by Japanese planetary scientists, who point out that the oceans are a self production of the Earth, originating from a thick blanket of... |

This weird space object observed repeatedly plunging close to the Sun has been puzzling astronomers: is it a comet or an asteroid? Now, it seems like a comet playing the asteroid. P/2007 R5 was first detected passing near the Sun in 1999 and spotted again in 2003 by the Solar and Heliospheric Observatory (SOHO) space... |

Should we rely by 2036 on Bruce Willis' deep-core drilling skills or should we take a more scientific approach to the asteroid 99942 Apophis? By 2036, people on Earth could see the Armageddon movie turned into reality. British space engineers have already unveiled designs for the development of a satellite that ... |

A breakup in the asteroid belt of the Sun System has now been connected by an American-Czech team from Southwest Research Institute (SwRI) and Charles University in Prague to the catastrophic event that destroyed the dinosaurs and many contemporaneous species 65 million years ago, after combining observations with va... |

We have barely escaped from an Armageddon. Next time we may not be that lucky. That's why some see the moon as our possible escape in case such a scenario happens. NASA is already planning a permanent lunar outpost by 2024. "But that plan should be expanded to include a way to preserve humanity's learning, ... |

At least five mass extinctions may have occurred in the history of our planet, meaning that in a relatively short period of time, a large number of species have disappeared. Probably the most famous one took place 65 million years ago at the end of the Cretaceous period, when the dinosaur domination reached its end.... |

Astronomers have just discovered another unusual celestial body in our solar system. It's a small asteroid, only 1 kilometer across that seems to follow Mars during its rotation cycle around the Sun. This is the first object of its kind to show this unusual movement.Mars has two moons, Phobos and Deimos, which ... |

Scientists performed a new study to evaluate what countries are most at risk of what they call "small" asteroid impact. The term small must not be taken literally, since a 1-kilometer-wide asteroid may not be large in astronomical terms, but it still can produce a disaster.Using a new computer software, called NEOim... |

This weekend, NASA will launch a new mission, the Dawn spacecraft, which will venture into the asteroid belt to rendez-vous with two of the largest asteroids in the solar system, Ceres and Vesta. The asteroid belt, located between Mars and Jupiter, is the largest concentration of asteroids in the solar system, wher... |

Presently, the widely accepted theory about the formation process of the Moon is a giant impact between the early Earth and a celestial body the size of Mars, that threw out enough material in orbit that accreted in time to form our only natural satellite.However this hypothesis is not accepted by all the scientific... |

NASA's internal procedure for tracking potentially dangerous asteroids that could hit Earth and for countermeasures designed to deflect the space objects is deeply flawed and heavily criticized because it exaggerates the cost and difficulty of the program.The agency had one year to prepare plans for a survey th... |

Asteroid Itokawa repeatedly shakes the booty; that's what the tiny pebbles on the near-Earth cosmic object show. Like a jiggled jar of mixed nuts, shaking on the near-Earth asteroid is sorting loose rock particles on its surface by size, causing the smallest grains to sink into depressions, a new study suggests... |

A cosmic impact between two bodies resulted in a 200 mile-wide iron meteorite, the size of Lake Mead, behind Hoover Dam, left to chill out in space, and which produced roughly 60 smaller ones.It is believed that asteroidal bodies are just leftover debris from the collisions and subsequent melting that happens when p... |

The space rock, dubbed 2006 VV2, came within 2.1million miles of hitting us - which is a near miss in space terms, even though that's about nine times farther away than the moon.The asteroid was flying past Earth on Friday night, at 11 p.m. (PDT), and on Saturday 7 a.m. GMT for Europe.There was no danger of col... |

Early in the morning of June 30, 1908, in the Tunguska region of Siberia about 1,000 km (600 miles) north of Irkutsk, an asteroid about 60 meters (200 ft) in diameter entered the Earth's atmosphere, resulting in an immense explosion, centered about 8 km (5 miles) above the forest below. Trees were flattened ove... |

Researchers have measured for the first time a slight force from sunlight that affects the spin rate of the asteroids, a characteristic useful in forecasting fine-tune long-term asteroid orbits and solves the mystery of the rear moonlet displayed by some asteroids. "Sunlight can make asteroids spin so fast they break... |
