estas son las ‘arañas negras’ que han detectado en la superficie de marte

un fenónemo intrigante

Recientemente, la ESA (Agencia Espacial Europea, por sus siglas en inglés) desveló imágenes satelitales de una ciudad de Marte y estas dieron la impresión de parecer un cúmulo de arañas en la superficie del Planeta Rojo, causando mucha curiosidad en la comunidad científica y aficionados del tema.

En un comunicado de prensa, la ESA refirió que estas figuras fueron halladas “cerca del polo sur de Marte”; y fueron captadas con el instrumento CaSSIS (Color and Stereo Surface Imaging System) del ExoMars Trace Gas Orbiter de la Agencia.

¿Qué son estas ‘arañas negras’ captadas en la superficie de Marte?

En la denominada ‘Ciudad Inca’ de Marte, la ESA halló ‘arañas negras’. Se trataría, en realidad, de erupciones estacionales compuestas por dióxido de carbono. De acuerdo con la ESA, “estas características se forman cuando el sol de primavera cae sobre las capas de dióxido de carbono depositadas durante los oscuros meses de invierno”.

Es por ello que, “la luz solar hace que el hielo de dióxido de carbono en la parte inferior de la capa se caliente y se convierta en gas, que luego se acumula y se rompe a través de losas de hielo superposición”.

La ESA explicó que el gas “que se emana provoca grietas en el hielo que, después, es disparada y se asienta en la superficie creando manchas de color oscuro”. Es decir que, efectivamente, no se trata de ningún tipo de arácnido que se encuentra en el Planeta Rojo.

La imagen data del 4 de octubre de 2020 y, según la Agencia, “está centrada a aproximadamente 323°E/75°S”.

La ESA detalló que la superficie marciana con ‘arañas’ es un segmento rodeado de una cuenca de cráteres erosionados. La imagen provista por la Agencia son manchas oscuras con zarcillos que recuerdan misteriosamente a dicho animal.

Además de ofrecer esta información, la Agencia se tomó el atrevimiento de bromear en su comunicación, asegurando que, en realidad, las arañas acechan en lo profundo del territorio marciano. Esta región es conocida como Angustus Labyrinthus, y fue descubierta en 1972.
