Some gas tendrils between two galaxies indicate that a high-speed collision of the celestial bodies once took place. Scientists look up to this as a possible clue to the reason so many of the galaxies are unable to form new stars.One of the two is the spiral galaxy NGC 4438 situated about 50 million light years away ... |

A recent study proves that the difference of landscape between the northern and the southern hemispheres of Mars, as well as the concentration of the planet's magnetic field in the southern hemisphere, could have been caused by the same giant collision.There are still intriguing questions related to our red neig... |

By observing vast masses of dust accompanying a distant binary star system, US scientists concluded that it's possible that 2 planets similar to Earth violently collided 300 million light years away from us. Benjamin Zuckerman, an astronomer at the University of California in Los Angeles, who worked on the... |

Images provided by NASA's Hubble Space Telescope reveal that the collision between Jupiter's Great Red Spot and the Third Red Spot has all but destroyed the latter. All that was left behind was only a deformed and pale structure that is likely to be sucked completely into the giant anticyclone that has been... |

Unlike most of the individual celestial bodies in the universe, which tend to take the shapes of spheres (the geometrical object with minimum surface area in relation to volume), asteroids come practically in all the possible shapes and sizes, although why this happens remained largely unknown until now. By studying ... |

Supergiant high-mass X-ray binaries, HMXB for short, are stellar systems consisting of a supergiant star and a neutron star orbiting around it. HMXBs are relatively rare in the universe and are believed to be only a short phase in the life of binary star systems. At the time when ESA's gamma-ray space observator... |

A team of researchers from the UK states that Saturn's F ring is the most dynamic of all other rings, since it can change its features either in only a few hours or in a couple of years, probably due to large scale collisions taking place inside it. If this is truly the case, then the further study of the proces... |

Why study the star formation process in individual galaxies when the debris left behind by colliding galaxies makes matters so much simpler? In a press conference at the American Astronomical Society, Mederic Boquien from the University of Massachusetts showed that the study of the star formation process is much more... |

Many people don't know this but there are about 5,000 Near Earth Objects at least 10 kilometers wide that may one day decide to come crashing down on the surface without us even knowing. The consequences of an impact with such a large object are now known, but considering that an object that size may have been r... |

A planet roughly the size of Mars is on a collision course with the Earth. Eventually, the two planets collide and the Moon and the Earth are created in the outcome. Or at least that's what the Moon formation model says that happened some 4.5 billion years ago. But there is something missing. The Moon is here, t... |

The Hubble Space Telescope, currently operated by the NASA/ESA collaboration, celebrates 18 years since it was launched into space. In order to mark this moment, the Hubble collaboration is now launching the vastest amount of individual images ever released at once for public use - 59 new images - presenting dramatic... |

The first of these objects, 2003 EL61, was discovered back in 2005 and appears to be a strange shaped body rotating rapidly and chaotically about its axis. The fact that other five objects were found in the same orbit in 2007 suggests that all may have originated from a larger object destroyed during a collision abou... |

It is widely believed that the Earth and the Moon, the way we know them today, could have been created during an impact between a planet roughly the size of Mars and the 'original' Earth. The collision between the two bodies completely destroyed them both, however gravity eventually pulled the cloud of debr... |

A few days ago, 13 year-old German Nico Marquardt seemed to have embarrassed all NASA scientists when he announced that the odds of asteroid Apophis hitting the Earth in 2036 have been greatly underestimated. The funny thing is that many sources rushed to state that NASA and the ESA confirmed the schoolboy's res... |

2004 MN4, or most popularly known as asteroid 99942 Apophis, is a near Earth asteroid discovered in December 2004. Apophis measures about 400 meters in diameter and upon its discovery, it was given a chance of 2.7 percent that it will hit our planet in 2029. On 19 October 2006, NASA estimated that Apophis had a chang... |

Because light does not travel instantaneously through space, when we look towards distant objects in the universe we actually see them as they appeared in their past. By using this property, astronomers are able to observe how galaxies looked, back in the early days of the universe. Just recently, they discovered wha... |

Behemoths up to a billion times the mass of our Sun lie in our universe, swallowing up matter to hide it forever from the eyes of any outside observers. Not even light can escape their massive gravitational pull, that's why they are called black holes; they do not emit any form of electromagnetic radiation, thus... |

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... |

Located more than 320 million light years away, in the Eridanus constellation, the galaxy NGC 1132 represents a class of giant elliptical galaxies, surrounded by a group of dwarf galaxies named by astronomers, the 'fossil group.'

Such gas flow observations may eventually provide data that woul... |

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. How is this even possible, all of a sudden Mars is more important to us than Earth? I mean, we only found out about 2007 TU24 two days before the asteroid made a flyby ... |

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... |

We know it's out there, but we can't see it because it doesn't emit light. So how do you find a dark matter cloud? Well, if you consider the fact that most of gravitational fields produced in the universe are associated with dark matter existence, then the problem is solved. Astrophysicist Catherine He... |

The study of exoplanets and other solar systems is in high gear ever since the discovery of the first extrasolar planet back in 1996, finding new and interesting facts about solar systems formation processes. The same thing is available for an object orbiting a distant star, found nearly four years ago. The gas giant... |

Asteroids, like most of the bodies in the solar system, have stable orbits around the Sun, as all of them have their origins in the debris left behind by the planet formation process. They are spread through all over the solar system, but are mostly concentrated in an area of space called the asteroid belt, situated ... |

NASA's Hubble space telescope has taken new images of an elliptical galaxy, about two billion light-years away from Earth, as part of a research project led by UC Riverside's Gabriela Canalizo.

Some astronomers used computer simulations to prove that in a galaxy collision, the net momentum carried by the radiation produced by the merger of the two central black holes gives the remnant black hole a large kick in the opposite direction, and that would make it recoil at speed up to ten million miles per hour,... |
