Peque\u00f1as cuentas de vidrio, extra\u00eddas de muestras tra\u00eddas a la Tierra por la misi\u00f3n china Chang\u2019e-5, han permitido confirmar que la Luna experiment\u00f3 erupciones volc\u00e1nicas hasta hace unos 120 millones de a\u00f1os. Aunque hay abundante evidencia geol\u00f3gica de la antigua actividad volc\u00e1nica en la Luna, hasta el momento no se ten\u00eda certeza sobre cu\u00e1nto tiempo se hab\u00eda prolongado. Un nuevo estudio que publica Science encabezado por la Academia China de Ciencias estudi\u00f3 unas 3,000 cuentas volc\u00e1nicas de vidrio tra\u00eddas de la Luna. Muestras recogidas por las misiones Apolo, Luna y Chang’e-5 hab\u00edan demostrado anteriormente que hubo vulcanismo bas\u00e1ltico generalizado desde hace unos 4.400 a 2.000 millones de a\u00f1os. El nuevo estudio demuestra que el vulcanismo persisti\u00f3 mucho m\u00e1s tiempo de lo que se sospechaba anteriormente, al menos en una escala m\u00e1s peque\u00f1a y localizada. El equipo examin\u00f3 las composiciones qu\u00edmicas, las texturas f\u00edsicas y los is\u00f3topos de azufre de las cuentas para distinguir los vidrios volc\u00e1nicos potenciales de los producidos por impactos de meteoritos.<\/p>\n","protected":false},"excerpt":{"rendered":"
