La luna tiene m\u00e1s agua de lo que se cre\u00eda, seg\u00fan las \u00faltimas mediciones de la NASA. Durante a\u00f1os se crey\u00f3 que la luna era seca, pero despu\u00e9s de varios experimentos en los que se bombarde\u00f3 parte del sat\u00e9lite, se confirm\u00f3 que s\u00ed hay agua y hielo en la luna.<\/span><\/span><\/span><\/p>\n

<\/p>\n

Pero una cosa es la superficie y otra es el interior del sat\u00e9lite. Ahora, cient\u00edficos que analizaron restos de lava de antiguos volcanes lunares, reportan que los fragmentos contienen casi la misma cantidad de agua que los fragmentos de este tipo que se encuentran en la Tierra, lo que significar\u00eda que hay bastante agua dentro de la luna<\/strong>, al igual que en nuestro planeta.<\/span><\/span><\/p>\n

\u201cTengo que admitir que estamos sorprendidos\u201d, dijo Erik H. Hauri, uno de los cient\u00edficos de la investigaci\u00f3n del Carnegie Institution y autor del paper<\/em> que se publicar\u00e1 en la revista Science.<\/span><\/span><\/p>\n

Muchos cient\u00edficos, incluidos tres de los co-autores del estudio actual, predec\u00edan que no se iba a encontrar mucha agua.<\/span><\/span><\/p>\n

La investigaci\u00f3n<\/span><\/span><\/h2>\n
\"\" <\/span><\/span> <\/p>\n

Vidrio contenido dentro de un cristal de Olivino<\/span><\/span><\/p>\n<\/p><\/div>\n

El nuevo trabajo comenz\u00f3 cuando un profesor de ciencias geol\u00f3gicas le pas\u00f3 un frasco con tierra de la luna al estudiante Thomas Weinreich en la Universidad de Brown, pidi\u00e9ndole que buscara si hab\u00eda part\u00edculas interesantes.<\/span><\/span><\/p>\n

Lo que se hab\u00eda estudiado anteriormente eran peque\u00f1as piezas de vidrio volc\u00e1nico que hab\u00edan sido tra\u00eddas a la Tierra por astronautas de las misiones Apollo. Los vidrios ten\u00edan agua, pero no mucha.<\/span><\/span><\/p>\n

Weinreich examin\u00f3 grano por grano la tierra que le pasaron bajo el microscopio, encontrando entre el polvo algunos cristales, que adentro conten\u00edan vidrio. Los cristales, formados de olivino<\/span><\/a><\/span>, hab\u00edan prevenido que los vidrios que conten\u00edan adentro perdieran el agua. As\u00ed que cuando se examinaron estos vidrios que hab\u00edan estado aislados se encontraron entre 20 y 100 veces m\u00e1s agua que en los cristales que se hab\u00edan examinado antes, comparable a lo que se encuentra en la lava y magma terrestres.<\/span><\/p>\n

\u201cHay una reserva ah\u00ed abajo en la luna que tiene la misma concentraci\u00f3n de agua que algunas de las reservas del manto superior de la Tierra. Eso es seguro\u201d, concluy\u00f3 Alberto E. Saal, el profesor que le encarg\u00f3 la tarea a Weinreich.<\/span><\/p>\n

Ahora, no se sabe exactamente cuan extensa es esta reserva. Pero si la luna tiene agua adentro, es posible que el hielo que hay al fondo de los cr\u00e1teres en el sat\u00e9lite haya salido de volcanes, en lugar de impactos de cometas.<\/span><\/p>\n

El descubrimiento tambi\u00e9n le quita un poco la validez a la teor\u00eda que dice que la luna se form\u00f3 despu\u00e9s de una colisi\u00f3n entre la Tierra y otro planeta del tama\u00f1o de Marte hace como 4.600 millones de a\u00f1os. El choque habr\u00eda provocado un anillo de escombros a muy alta temperatura, lo que habr\u00eda provocado que el agua se evaporara y se formara una luna seca.<\/span><\/p>\n

El descubrimiento de agua se suma a los misterios respecto de c\u00f3mo se form\u00f3 la luna, que tiene a los cient\u00edficos tratando de entender c\u00f3mo el agua calza dentro de los datos que ya se tienen de este sat\u00e9lite.<\/span><\/p>\n
