Analyses have shown that Tagish Lake fragments are of a primitive type, containing unchanged stellar dust granules that may have been part of the cloud of material that created our solar system and Sun. The double, and not the expected single, plume formation of debris, as seen in video and photographs of the 2013 Chelyabinsk meteor dust trail and believed by Peter Brown to have coincided near the primary airburst location, was also pictured following the Tagish Lake fireball,[14] and according to Brown, likely indicates where rising air quickly flowed into the center of the trail, essentially in the same manner as a moving 3D version of a mushroom cloud. The Tagish Lake C2 (ungrouped) carbonaceous chondrite fall of January 18, 2000, delivered about 10 kg of one of the most primitive and physically weak meteorites yet studied. On January 18, 2000, a carbonaceous chondrite meteorite now known as "Tagish Lake", fell on the frozen surface of the Taku Arm. [2] Except for a greyish fusion crust, the meteorites have the visual appearance of a charcoal briquette. ュ湖(Tagish Lake)付近に落下した隕石である。 The Tagish Lake meteorite is one of the best-known meteorites to have fallen, partly because of how unique it is.

Tagish Lake -- A Meteorite from the Far Reaches of the Asteroid Belt P ieces of a 56-metric-ton meteorite rained down over a wide area of Canada on January 18, 2000. The cosmic rock lit up the morning sky as it fell, causing loud bangs and dust clouds to … [4] The fragments were transported in their frozen state to research facilities after they were collected by a local resident in late January, 2000. The delicate charcoal found on Tagish Lake indeed is a rare example of a meteor class called carbonaceous chondrites: meteorites which make up about three per cent of the space rocks recovered. A meteorite that fell in northern Germany in 2019 contains carbonates which are among the oldest in the solar system; it also evidences the earliest presence of liquid water on a … After the Tagish Lake meteorite crashed to earth in northern British Columbia in January 2000, it was hailed as the most primitive and pristine material from anywhere in … The Tagish Lake meteorite is a carbon-rich (4 to 5 weight %), aqueously altered carbonaceous chondrite and contains high concentrations of … Tagish Lake is a C2-ungrouped carbonaceous chondrite that fell in Canada in 2000. Tagish Lake has a much lower density than any other type of chondrite and is actually composed of two somewhat different rock types. The major difference between the two lithologies is in the abundance of carbonate minerals; one is poor in carbonates and the other is rich in them. Jim Brook recovered several dozen meteorites totaling ~ 1 kg on the ice of Taku Arm, Tagish Lake, on January 25 and 26 (coordinates of first find given above). The meteorite’s spectacular entry was witnessed by several residents, and was also detected by seismographs, as well as satellites in Earth orbit. The meteoroid detonated at an altitude of 30 to 50 km from Earth’s surface, and many of the resulting fragments landed on the frozen surface of Tagish Lake, British Columbia. In fact, Tagish Lake contains more of the nanodiamonds than any other meteorite. These later fragments were mostly found to have sunk into the ice by a few cm to more than 20 cm, and had to be collected out of meltwater holes, or cut in icy blocks from the frozen surface of Tagish Lake. Eyewitness accounts in the vicinity of Whitehorse, Yukon accurately constrained the ground track azimuth from either side. there are only eleven meteorite falls with accurately determined pre-entry orbits, based on photographs or video recordings of the fireballs themselves taken from two or more different angles. They have been stored at temperatures below freezing. The Tagish Lake meteorite fell last year on a frozen lake abundance and distribution, the only difference being a lower in Canada and may provide the most pristine material of ratio of linear to branched acids. WASHINGTON (AP) -- A bus-sized meteorite that blazed to Earth in a spectacular fireball in January could have delivered the most pristine primordial matter ever recovered from space and carry important new clues about the origin of life. Dust clouds from terminal fragmentation events were widely observed. Based on eyewitness accounts of the fireball caused by the incoming meteor and on the calibrated photographs of the track which it had left behind and which was visible for about half an hour, scientists have managed to calculate the orbit it followed before it impacted with Earth.

Meteoritul s-a ciocnit cu Pământul acum aproape 10.000 de ani în urmă. According to the Meteoritical Bulletin (MB 84), the Tagish Lake fall was preceded by a bright fireball visible in northern British Columbia and the southern Yukon, and loud explosions the morning of January 18th, 2000. The fireball was also detected by satellites in Earth orbit. Find all the transport options for your trip from Atlanta to Tagish Lake (meteorite) right here. However, it is estimated that only 1.3 tonnes remained after ablation in the upper atmosphere and several fragmentation events, meaning that around 97% of the meteorite had vaporised, mainly becoming stratospheric dust that was seen as noctilucent clouds to the northwest of Edmonton at sunset, some 12 hours after the event. The Tagish Lake meteorite fell at 16:43 UTC on 18 January 2000 in the Tagish Lake area in northwestern British Columbia, Canada. Meteorite Identification Pages: A suggested gift: Put a meteorite in a membrane box--~$60 and up for Canyon Diablo, $35 and up for NWA 869, $80 and up for Sikhote-Alin ($45 for fragments). The pieces of the Tagish Lake meteorite are dark grey to almost black in color with small light-colored inclusions, and a maximum size of ~2.3 kg. [2] Most of the stony, carbonaceous fragments landed on the Taku Arm of the lake, coming to rest on the lake's frozen surface. Tagish Lake fullerenes and the remaining bulk acid residues. Unlike Murchison, the Tagish Lake meteor shows no signs of amino acids, but shows a number of cyclic and ring-aromatic carbon chains. Dust clouds from terminal fragmentation events were widely observed. Many of the specimens recovered in the spring had melted into the ice of the lake, some of them over 20 cm (~ 8”) deep, and had to be cut out of the ice! The most primitive matter in the solar system The Tagish Lake Meteorite… Based on reconstruction of the meteoroid’s trajectory and orbit before impact, as well as spectroscopic and near-infrared photometric analyses, Tagish Lake is believed to be derived from a D-type asteroid, the most likely candidate being 773 Irmintraud.
