MURCHISON meteorite CM2, No reservation!!!!! - 0.04 g

Murchison es uno de los meteoritos más fascinantes, codiciados y difíciles de encontrar Los científicos han descubierto polvo de estrellas que nacieron hace entre 5.000 y 7.000 millones de años. “Estos son los materiales sólidos más antiguos jamás encontrados, y nos cuentan cómo se formaron las estrellas en nuestra galaxia” Los pequeñísimos “fragmentos de estrella” analizados provienen de un astro que nació hace unos 7.000 millones de años durante un periodo de intensa formación estelar. El material expulsado por la estrella, primero vagó solo por el espacio interestelar y después quedó sepultado dentro de un cuerpo de roca, donde se preservó intacto durante miles de millones de años. Esa roca, penetró en nuestra atmósfera y se descompuso en todos los fragmentos del meteorito Murchison que cayeron sobre Australia en 1969. Haber hallado estos compuestos supone un hito, pues la mayoría del polvo estelar que queda depositado en meteoritos es destrozado por la presión. Solo en torno al 5% de los meteoritos conocidos contienen material de este tipo y su abundancia no suele superar las pocas partes por millón Es una de las caídas de una condrita carbonácea más famosa y estudiada Las condritas carbonáceas comprenden alrededor del 4% de todos los meteoritos En Expometeoritos, nos encargamos de la divulgación, charlas, talleres, análisis, clasificación y exposiciones de Meteoritos. Todas nuestras piezas están certificadas y además, entregamos el análisis de la composición química si el valor de la pieza supera los 300€, realizado en nuestras instalaciones por Espectrografía de Rayos X.

Murchison is one of the most fascinating, coveted, and difficult to find meteorites.

Scientists have discovered stardust that originated between 5,000 and 7,000 million years ago. "These are the oldest solid materials ever found, and they tell us how stars formed in our galaxy."

The tiny "star fragments" analyzed come from a star that was born about 7 billion years ago during a period of intense star formation. The material expelled by the star first wandered alone through interstellar space and then became buried inside a rocky body, where it remained intact for billions of years.

That rock entered our atmosphere and broke up into all the fragments of the Murchison meteorite that fell over Australia in 1969.

Finding these compounds is a milestone, as most of the stardust that remains deposited in meteorites is destroyed by pressure. Only about 5% of known meteorites contain this type of material, and its abundance rarely exceeds a few parts per million.

It is one of the most famous and studied falls of a carbonaceous chondrite.

Carbonaceous chondrites comprise about 4% of all meteorites.

At Expometeoritos, we are in charge of the dissemination, talks, workshops, analysis, classification and exhibitions of Meteorites.

All our parts are certified and we also provide an analysis of the chemical composition if the value of the part exceeds €300, carried out in our facilities using X-ray spectrography.
