The 250-gm rock <DIV></DIV>>piece that holds the promise of unravelling the many mysteries of <DIV></DIV>>solar system, is a part of the meteorite that landed in Orissa on <DIV></DIV>>September 27, and has been brought here by a team of PRL scientists. <DIV></DIV>> <DIV></DIV>>Although the scientists here are not sure of the age of the rock at <DIV></DIV>>the moment, looking at the chondrules (small rounded structures on <DIV></DIV>>the rock), they say it appears to be part of some of the most <DIV></DIV>>primitive material in space. Scientists say since the rock is <DIV></DIV>>radioactive, tests can reveal its age and its detailed study will <DIV></DIV>>help them infer what happened in the solar system way back. <DIV></DIV>> <DIV></DIV>>"This rock (meteorite) is no ordinary piece of stone, as it has in <DIV></DIV>>it imprints of the changes that have taken place in the space during <DIV></DIV>>the last 4.6 billion years," said a scientist from PRL who visited <DIV></DIV>>Orissa. PRL scientists say the iron veins in the rock suggest that <DIV></DIV>>after its formation, the rock was subjected to intense heat, <DIV></DIV>>following which iron must have flowed into the cracks. <DIV></DIV>> <DIV></DIV>>A meteorite is a piece of extra-terrestrial solid mass that has <DIV></DIV>>survived atmospheric friction and landed on earth. <DIV></DIV>> <DIV></DIV>>Scientists say when these pieces of extra-terrestrial rocks orbiting <DIV></DIV>>the solar system collide with each other, they leave their orbits <DIV></DIV>>and travel through earth's atmosphere to land on earth. Usually, a <DIV></DIV>>major chunk of the rocks burn during their passage, but whatever <DIV></DIV>>matter survive the friction and reach the earth are mines of <DIV></DIV>>information. <DIV></DIV>> <DIV></DIV>>Scientists at PRL say these "meteoric rains" are very important as <DIV></DIV>>they provide us with "free samples" of rocks from space. <DIV></DIV>> <DIV></DIV>>PRL scientists said the rock will be a subject of intense study to <DIV></DIV>>find out details about its mineralogy, composition, history and <DIV></DIV>>various other factors. <DIV></DIV>> <DIV></DIV>> <DIV></DIV>>______________________________________________ <DIV></DIV>>Meteorite-list mailing list <DIV></DIV>>Meteorite-list_at_meteoritecentral.com <DIV></DIV>>http://www.pairlist.net/mailman/listinfo/meteorite-list <DIV></DIV></div><br clear=all><hr> <a href="http://g.msn.com/8HMAENUS/2737??PS=">Instant message with integrated webcam using MSN Messenger 6.0.
