Hallan nueva evidencia sobre posibilidad de vida en marte

Las concentraciones elevadas de zinc y germanio -similares a las que aparecen juntas en la Tierra-, Marte podría brindar condiciones para la existencia de microbios, señala hoy la Universidad canadiense de Guelph.

Nuevos datos recogidos en Marte por la NASA, a través del explorador Curiosity, refuerzan evidencias acerca de la posible existencia de vida en el planeta rojo.

Los investigadores de la agencia aeroespacial estadounidense hacen referencia a indicativos de actividad hidrotérmica en rocas sedimentarias de un cráter marciano, lo cual amplía el espectro de condiciones para la habitabilidad.

Jeff Berger, geólogo de la Universidad de Guelph y autor principal del nuevo estudio, sostiene que las elevadas concentraciones de zinc y germanio en el cráter Gale pueden eventualmente explicarse por efectos de actividad hidrotérmica en la zona.

Según los expertos, las concentraciones de zinc y germanio encontradas en el cráter Gale son de 10 a 100 veces mayores que las existentes en la corteza marciana típica. Ambos elementos químicos aparecen a menudo juntos en la Tierra, en depósitos hidrotérmicos que contienen azufre.
