A never - before - seenextraterrestrial mineralwas footle inside a meteorite find nearly 70 yr ago .
According to a new study first report by the Australian news land site , The Age , the mineral does n’t course come about anywhere on our satellite ; as such , it ’s been ascertain only as a homo - made version .
The Wedderburn meteorite was first discovered in 1951.
The Wedderburn meteorite was first happen upon in 1951 near Wedderburn in Victoria , Australia , and is now part of the Museums Victoria aggregation . When it was first find , the sway was " lemon - sized " and weighed 210 grams ( 7.4 ounces),according to the Museums Victoria Collections . Since the space sway ’s discovery , researchers from around the world have been studying slices of it to translate what it ’s made of and where it came from .
Last class , researchers at the California Institute of Technology conducted the latest of such sketch . Using an electron - beam microscope and electron probe , they dissect a slice of the quad John Rock and happened upon a rare , previously unnamed mineral that does n’t by nature occur on our planet .

The mineral is made up of a special formula of iron and atomic number 6 atoms . The researchers named it " edscottite , " after Edward R.D. Scott , a cosmochemist at the University of Hawaii at Manoa . Scott was the first to let out this mineral in the meteorite and see its chemic make-up in the early seventies , but he was not able to determine its crystallization structure , said lead author Chi Ma , a older stave scientist and mineralogist at Caltech .
A mineral is defined by a chemical composition and crystal social organisation . For instance , both diamond and graphite are both made up of C , but they have different crystal structures , Ma said . In this new written report , Ma and his team estimate out the mineral ’s crystal structure and thus had it approved as a new mineral .
The Wedderburnmeteorite likely follow from an asteroidthat " somehow got knocked off its course of action and headed to Earth , " Ma told Live Science . The meteorite itself is probable the shatter clay of a small major planet that collide with other celestial object in the earlysolar system , he added . The mineral edscottite could have formed when nickel - full-bodied atomic number 26 meteorite such as Wedderburn slow cool , he said .
" Every mineral has a voice and its own story to assure , " Ma enunciate . " Each Modern E.T. mineral typify a classifiable geological formation environment and can provide insights into processes active in the solar nebula , on asteroid , the lunar month and Mars . " Ma and his squad hope to canvas other meteorites to confirm whether they also contain edscottite .
