El vehículo explorador Perseverance de la NASA ha descubierto rocas en el canal de un río seco que podrían contener señales de vida microscópica antigua, según los científicos.

Washington

NASA's Perseverance rover has identified a rock on Mars that could hold the most compelling evidence of ancient life ever found on the planet. The rock, discovered in an ancient riverbed, displays unusual markings that NASA scientists believe may be biosignatures of Martian microbes from more than three billion years ago.

NASA officials, including acting administrator Sean Duffy and head of science Dr. Nikki Fox, have highlighted the significance of this find, noting that it stands out from surrounding rocks and represents the most interesting observation in the ongoing search for extraterrestrial life. The discovery brings renewed attention to the question of whether life ever existed beyond Earth.

Las rocas halladas en Marte podrían contener señales de vida antigua

Mucho antes de que el astrónomo Galileo Galilei contemplara Marte por primera vez a través de un telescopio, nuestro vecino planeta rojo vecino había cautivado nuestra imaginación. Los humanos se han preguntado durante mucho tiempo si hay o hubo vida en la cuarta roca desde el sol. Como informa Mark Strassman, una estrella del rock llamada Perseverancia puede haber desenterrado por fin la respuesta. Este es un selfie de Perseverance, el rover que encontró esta roca, potencialmente la más roca más significativa de Marte que la NASA haya estudiado jamás. Sean Duffy es el administrador en funciones de la NASA. Esto muy bien podría ser el signo más claro de la vida que hemos encontrado en Marte, que es increíblemente emocionante. Estas manchas en la roca dan vértigo a la NASA, una potencial biofirma de microbios marcianos en un antiguo cauce de más de tres mil millones de años. ¿Qué lo hizo destacar? Simplemente no se parecía a las rocas de alrededor. La Dra. Nikki Fox es la directora científica de la NASA. Esta es de lejos la observación más interesante que hemos hecho mientras seguimos buscando vida en otros lugares del sistema solar. Es una roca para la eternidad. Y para la gran pregunta, ¿estamos solos? Mark Strassman, Noticias CBS, Atlanta.
