"Elgygytgyn":
Vor 3,6 Millionen Jahren schlug hier ein Meteorit ein

Der Kratersee, der sich danach gebildet hat, soll nun Aufschlüsse über die Klimageschichte der Arktis ermöglichen
Wien - Ein internationales Forscherteam möchte anhand eines Kratersees im Nordosten Sibiriens die Klimageschichte des hohen Nordens mit bisher ungeahnter Genauigkeit nachzeichnen. Die Arbeiten des International Continental Scientific Drilling Program (ICDP) am Elgygytgyn-See haben begonnen, die Auswertung der Bohrkerne laufen unter österreichischer Leitung. Christian Köberl, international renommierter Impakt-Forscher der Uni Wien, hat die Aufgabe übernommen.

Dass sich die Wissenschafter ausgerechnet diesen See ausgesucht haben, ist kein Zufall. "Der See wurde vor rund 3,6 Millionen Jahren durch einen Meteoriteneinschlag verursacht und ist deswegen sehr tief", erklärt Köberl. Eine maximale Tiefe von 170 Metern wurde ermittelt, das sorgt dafür, dass das Gewässer nie komplett durchfriert. So ist die Klimageschichte, welche die Forscher anhand der Sedimentschichten ablesen wollen, lückenlos erhalten. Nicht zuletzt wollen die Wissenschafter klären, wie die Arktis auf Erwärmung und Abkühlung reagiert.

Sedimente und was darunter liegt

Erste Bohrungen haben ergeben, dass die vom See abgelagerten Schichten wenigstens seit rund einer Million Jahren ungestört sind. Das entspricht einer Sedimentschicht von rund 100 Metern. "Darunter findet sich Sand, das weist darauf hin, dass der See zu dieser Zeit ausgetrocknet war", so Köberl. Die genaueren Umstände müssen allerdings erst geklärt werden. Insgesamt sind die Sedimente rund 300 Meter mächtig.

Als Impakt-Forscher interessiert Köberl aber auch das, was sich unter den See-Sedimenten befindet, nämlich die Zeugnisse des Einschlags. Der Meteorit hat nämlich vor 3,6 Millionen Jahren in Vulkangestein eingeschlagen. Unter den See-Sedimenten erhofft sich der Wiener Forscher daher die durch den Einschlagsschock gezeichneten Gesteine zu finden. Letztendlich sollen daraus die freigesetzten Energien und die Größe des kosmischen Bröckerls errechnet werden.

Der See ist derzeit noch von einer 1,5 bis zwei Meter mächtigen Eisschicht bedeckt. Erst im Mai beginnt es zu tauen, im Juli und August ist er dann frei von Eis. Die Arbeiten sind mittlerweile angelaufen, die ersten Bohrkerne erreichten am 18. März die Oberfläche. Österreich ist seit Ende 2001 Mitglied beim ICDP, einer multinationalen Organisation, die sich mit wissenschaftlichen Bohrprojekten weltweit befasst. Unterstützt wird Köberl derzeit durch das Wissenschaftsministerium, für die weiteren Auswertungen hofft der Forscher auf die Genehmigung eines beim Wissenschaftsfonds FWF eingereichten Projekts.

科學家發現一粒微隕石“來歷不明”
2009年04月10日 20:48:56 　來源：新華網

新華網巴黎４月９日電（記者李學梅）一個由法國和美國科學家組成的科研小組經過研究證實，一粒早在約２０年前發現的微隕石雖含有玄武岩成分，但卻並非來自已知的玄武岩“專有”星球。這一研究發現在天文學界尚屬首次。
研究人員在新一期美國《國家科學院學報》上介紹說，這一被命名為“ＭＭ０４”的微隕石于１９９１年在南極洲被發現，質量只有幾微克，直徑不過１５０微米。經對其化學成分分析研究，他們發現它雖含有玄武岩成分，但卻既非來自月球，也非來自火星或灶神星。而之前發現的所有含有玄武岩成分的隕石，都分別來自這三個天體。
“我們發現過來自灶神星的玄武岩隕石，也有來自月球和火星的玄武岩隕石，”倫敦自然歷史博物館的專家卡羅琳·史密斯評論說，“但是對‘ＭＭ０４’的化學分析表明它不是來自這些地方。”
研究人員指出，這粒微隕石到底來自何處至今還是個謎，它很可能來自一顆還不為人知的行星。他們認為，對這粒微隕石繼續展開相關研究將有助于拓寬人類對行星的認識。

Austria Bolide Produces Bright Light and Sound 10APR09

Earthquake turns out to be an exploding meteorite
Hundreds of Carinthians were left terrified thinking they had been hit by an earthquake after a meteorite exploded over their homes early yesterday (Thurs, 9APR09).
Locals said the meteorite exploded at about 3AM with what sounded like an enormous thunder clap followed by rumbling and howling. Hans Handler from Velden told the newspaper Österreich yesterday: "I though it was either an earthquake or a crashing airplane."Experts at an observatory at Gerlitzen near Villach said the meteorite had reached a temperature of more than 1,000 degrees Celsius after entering the earth’s atmosphere. They added the bang it had caused had been heard over a wide area of the province.
Hermann Mucke, the long-time chief of an astronomical office in Vienna, told the newspaper: "The meteorite produced a glow of an electric nature. Most such meteorites are detected at altitudes ranging from 80 to 120 kilometres."
Mucke added, however, that it would be impossible to prove that the phenomenon had been a meteorite. He said there was only one so-called "fireball" camera in Austria, which was located in the Waldviertel far from Carinthia, and so there were no photos of what had lit up the Carinthian sky yesterday morning.

Tiny Rock Found in Antarctica Excites Astrochemists 8APR09

Tiny rock excites astrochemists
BBC NEWS
http://news.bbc.co.uk/2/hi/science/nature/7985788.stm

A "unique" micrometeorite found in Antarctica is challenging ideas about how planets can form.Detailed analysis has shown that the sample, known as MM40, has a chemical composition unlike any other fragment of fallen space rock. This, say experts, raises questions about where it originated in the Solar System and how it was created. It also means that astrochemists must expand their list of the combinations of materials in planetary crusts.

The detailed analysis of MM04 was led by Matthieu Gounelle from the Laboratory of Mineralogy and Cosmochemistry at the French Natural History Museum. Published in PNAS, the analysis revealed the "unique" chemical composition of MM04 despite it being only 150 microns across as its widest point - about half the width of a written full stop.

Micrometeorites are often seen as the 'poor man's space probe' Dr Caroline Smith, Natural History Museum Dr Caroline Smith, curator of meteorites at the Natural History Museum, London,UK, said the sample was important because of the role that the study of meteorites played in our understanding of Solar System and planetary formation.

MM04 was a basaltic achondritic micrometeorite, said Dr Smith. Achondritic meteorites were formed when the Solar System's planets were coming into being. The substances in such meteorites and the processes they have undergone can give clues about how the larger bodies were formed. By contrast, chondritic meteorites were formed during the the Solar System's early days before material had accreted into planets. They have not been altered by the melting and re-crystalisation that has utterly transformed the nature of, say, Earth rocks.

Dr Mahesh Anand, an astrochemist from the department of Earth & Environmental Sciences at the Open University, said: "It is fascinating as to how much information can be retrieved about the processes involved in planetary formation from tiny fragments of extra-terrestrial material that routinely arrive on Earth anonymously."For Dr Smith, the excitement of MM04 lay in the mystery of its origins."We have basaltic meteorites that are thought to come from an asteroid called 4Vesta and we also have basaltic meteorites from the Moon and Mars," said Dr Smith. "But [MM04's] chemistry does not match any of those places," she said. "It has to be from somewhere else."While its ultimate origins are a mystery it does have implications for the ways that astrochemists thought planets could be formed.

The analysis of MM04 showed that the "inventory" of such processes must be expanded, said Dr Smith."Micrometeorites are often seen as the 'poor man's space probe'," said Dr Smith "They land on Earth fortuitously and we do not have to spend millions of dollars or euros on a robotic mission to get them."

Colourful start to commute as fireball explodes in sky
Calgary Sun
Wed, April 1, 2009/ updated 2009-0401
by Katie Schneider

The commute to work got a little bit brighter yesterday when a multi-coloured fireball streaked across the Calgary sky and exploded like fireworks.
Patricia Larson was driving to work with her husband on 12 Ave. S.W., about 6:30 a.m., when she saw a bright blue-green light smear in a north-south direction and then break apart into fragments after about 20 seconds.
"It was so bright, a very cool colour -- I haven't seen one that bright and not that big," she said.
Martin Lewanzick was driving on Glenmore Tr., at 84 St. S.E., about the same time when he saw the fireball that he described as white and blue in colour explode before his eyes. "It was really low in the sky, it was really wild -- it looked like a welder's torch," he said. "It blew up right in front of me and broke into a million pieces and fizzled."
Alan Hildebrand, a University of Calgary planetary scientist and co-ordinator of the Canadian Fireball Reporting Centre, said he will review photos and talk to witnesses to determine if the space rock left behind any meteorites. The show was also seen in Edmonton, Red Deer and Regina areas.

Handyavi- North Central California Bolide 7APR09

Photo by Larry Stange (c) 2009 - YC Sentinel

This Bolide's duration was apprx. 1 second ending in a single brilliant explosion bright enough to be visible goodly distances and likely well into Nevada. Near Yuba City`s Eastern portion of Zenith.Estimated magnitude to be 3/4 full moon. Light curve is a clean single very large pulse. No post explosion products noted on this first filming by the Sentinel camera.
PDT = April 7, 2009 at 0359:31

update:
Examination of Handyavi frame records shows what appears to be a single piece may have been discharged a short distance from the point of explosion which became bright then faded out. Slow frame rate does not allow good tracking of post explosion by-products.

Speculation on this unusual event....
The extremely steep & sharp light curve suggests this fireball did not burn up. It may have just blown itself apart which would account for the one or two(?) visible light particles afterward.

Related? from Texas:
Do you have a guess to the source of your fireball. The reason I am asking is I just had a second major bolide a few mintues ago since saturday night.
This one this evening was very green with a bright terminal burst.The one saturday night was white and about a third of the way through it's flight it exploded and there was a stream of debris,with about 8 luminus bodies, following the main fireball.
Both look to me to be earth grazers, my guess is the radiant is somewhere between Virgo and Ophiuchus, maybe some where in the area of Serpens Caput.This best I can pin it down at this time.Anyone have any guesses to the source active?

North Eire-Security cameras clue to fireball 6APR09

Security cameras clue to fireball
Northern Ireland
BBC NEWS
http://news.bbc.co.uk/2/hi/uk_news/northern_ireland/7985093.stm
The light in the sky is thought to have been a shooting star
Security cameras in Northern Ireland may shed some light on the cause of a massive fireball in the sky on Sunday.
The shooting star was reported at about 1230 BST by people living as far apart as Donegal and Cork.
David Moore chairman of Astronomy Ireland said they were fairly certain it was a rock from space which could have landed somewhere in Ireland.
He said they were very keen to hear from anyone who has footage of what is suspected to be a meteor falling.
"We're fairly certain that it was a rock from space, a meteor which may have dropped a meteorite," he said.
"We are asking people to send in their reports, so we can triangulate on the path and figure out did it land on Ireland?"
The last time a meteorite was seen over Ireland was in 1999 over Carlow and there was a similar event over the skies of Northern Ireland 30 years earlier.
Mr Moore said that no pictures had yet come to light of the incident, as it only lasted a few seconds.
But, he said, security cameras often captured such explosions in the sky.
"What can happen is security cameras that are filming in car parks or outdoors can catch these shooting stars, these fireballs, accidentally. So if anybody has any footage of that, we would be delighted to see it.
"We think...it came from the west across the centre of Ireland, which means everybody would have seen it. We have reports from Cork and even from up as far as Donegal."
He said security cameras in Northern Ireland facing towards the south probably would have picked it up.
Anyone who saw it is asked to contact the Astronomy Ireland website on www.astronomy.ie.
"We will publish a report there in a few days," said Mr Moore.
"We will also predict where any meteorite might have fallen, as we did with Carlow in 1999. A lady found the meteorite in a small country lane.
"They will look like melted rocks, probably not very large. We are looking for objects that would fit, in that particular case, in a mug. But they could be larger."
