This photo provided by the Chicago Field Museum, taken on April 9, 2013, shows pieces of a meteor that exploded on the Ural Mountains in Russia after cataloging upon their arrival at the Chicago Museum.
The museum received nearly a kilo of small pieces of meteorite donated by a collector.
After a surprise meteorite on the Earth at 42,000 mph, it exploded over a Russian city in February, breaking windows and causing minor injuries. Scientists studying the consequences claim that the threat posed by space rocks to our planet is greater than they thought. Meteorites like the one that exploded above Chelyabinsk – and those that are even bigger and more dangerous – are probably four to five times more likely to touch the Earth than scientists thought before the explosion in flight February, according to three studies published Wednesday in Nature and Science journals. less

The is a current map of the solar system showing the orbits of terrestrial planets and the estimated position of thousands of known asteroids. It lacks comets, space probes and, of course, unknown asteroids. Even conservative estimates would suggest that for every asteroid in a dangerous orbit near Earth, there are hundreds more to discover. There are more than 300 known objects in orbits crossing the Earth, the majority of which are potentially capable of causing death and destruction on a scale unprecedented in the history of mankind.

In this screenshot taken from a video made with a dashboard camera, a meteor crosses the sky above Chelyabinsk, about 1500 km east of Moscow, Friday, February 15, 2013. A meteor estimated by scientists weighed 10 tons (11 tons) stagnated at a supersonic speed over the Ural mountains in Russia, triggering explosions that injured some 500 people and scared countless other people.

Meteor Crater is one of the youngest and best preserved impact craters on the planet. The crater was formed about 50,000 years ago when an iron-rich meteor of 30 meters wide and weighing 100,000 tons hit the Arizona desert at an estimated speed of 20 km / s. The resulting explosion exceeded the combined strength of current nuclear arsenals and created a crater of a width of 1.1 kilometers and a depth of 200 meters. Meteor Crater is a simple crater because it has no central terraces or ledges. The crater is formed in layers of Paleozoic sedimentary rocks, some of which are exposed in the nearby Grand Canyon. These rocks were raised and in some cases returned to the edge of the crater. Debris landslide and subsequent erosion partially filled the bottom of the crater with minor amounts of edge material and sediment.
The story of the Moon, heavily encumbered with craters, indicates that the Earth has also experienced many impact events at the beginning of its history. The processes of erosion and plate tectonics have combined to erase almost every crater on Earth. To date, only about 150 impact craters have been identified on Earth, and most of them are severely eroded or buried by subsequent rock units. The origin of this classic, simple meteorite impact crater has long been the subject of controversy.
The discovery of fragments of the Diablo Canyon meteorite, including fragments of gap deposits that partially fill the structure, and a range of shock metamorphic features in the target sandstone have proved its origin. Target rocks include Paleozoic carbonates and sandstones; these rocks were spilled just outside the edge during ejection. The bumpy deposits located just beyond the rim are remnants of the ejecta cover.
This aerial view shows the dramatic expression of the crater in the arid landscape. The crater was named in honor of Daniel Moreau Barringer, a mining contractor who championed an original impact to the crater in the early 20th century. less

The explosion of 1908 is generally estimated at about 10 megatons; he razed some 80 million trees for miles near the site of the impact. The meteor that crossed the Russian skies on Friday, February 15, 2013 is estimated at about 10 tons. It exploded with the power of an atomic bomb on the Ural mountains, about 5,000 kilometers west of Tunguska. less

On the other hand, after a close approach, it will be well placed for observers from the northern hemisphere. less

Soon, other data such as chemical composition, interior structure, and geological age will help scientists understand the history of this remaining protoplanet and its place in the early solar system.

Orionids peak tonight – and Seattle weather could let you see
The skies of Seattle are seldom clear enough for astronomical events and will probably be less clear by the end of October. But the city may well have the chance to see the Orionids for their heyday.
The meteor shower peaks late Sunday night (or more precisely early Monday morning), with about 15 to 30 meteors per hour or so at most.
And if you get away from the city lights enough, the Seattle skies may let you see them: the sky should be clear enough from the northwest, provided you can escape from the fog in the ground. rural areas.
This is not the only thing that works against you either. The moon is almost full, creating natural light pollution that will erase some of the weaker meteors that cross the sky.
And this year's peak is actually at the bottom of what showers like this one may be able to do; Certaines années, les Orionides peuvent atteindre 80 par heure, alors que les Perséides donnent normalement entre 100 et 200.
De plus, même si Seattle a connu un ciel dégagé, il y a également eu un brouillard meurtrier cette semaine qui a entraîné une visibilité très réduite.
Très brumeux ce matin, la plupart des sites d’observation de l’ouest de Washington affichant un brouillard épais. Pas beaucoup d'amélioration avant midi. Soyez prudent lorsque vous conduisez par faible visibilité ce matin. Les piétons et les cyclistes se démarquent en portant des vêtements de couleurs vives ou réfléchissants. #wawxpic.twitter.com/0h8zVgT2d8
Néanmoins, la possibilité d’un ciel dégagé à Seattle laisse entrevoir des perspectives plus prometteuses que celles que nous avons habituellement. Si vous décidez d'aller à la chasse aux étoiles, votre meilleur pari sera aux alentours de 2 heures du matin, bien qu'il soit possible de regarder à tout moment de la tombée de la nuit.
Bien que la douche tire son nom du point d'où elle semble provenir (la constellation d'Orion), vous devriez pouvoir les voir dans n'importe quelle partie du ciel. Pour un meilleur visionnage, la NASA recommande de chercher un endroit à l’écart des lumières de la ville, à plat sur le sol, les pieds orientés au sud-est.
Et si vous ne pouvez pas vous en sortir ce soir, ne vous inquiétez pas: cette tempête céleste est censée durer jusqu'au 7 novembre, selon la NASA.
