Mars valley reveals clues to ancient ocean and floods

Kiswahili

A vast valley on Mars offers new evidence that the planet once held large bodies of water. Shalbatana Vallis stretches about 1,300 kilometers near the equator and shows signs of powerful groundwater floods from billions of years ago.

The European Space Agency's Mars Express spacecraft captured fresh images of the northern section of the valley. These views highlight deep channels carved by ancient floods, collapsed terrain, and deposits of volcanic ash. The main channel measures around 10 kilometers wide and up to 500 meters deep in places.

Scientists identify vast hidden basin network under East Antarctica

Researchers have mapped a massive fan-shaped network of basins beneath the East Antarctic Ice Sheet, linking several previously studied features into one large geological structure. The discovery, published in a 2026 study, offers new insights into the continent's tectonic past and its influence on current ice movement.

Study finds hidden channels speed Antarctic ice melt

A new study shows that channels beneath Antarctic ice shelves can trap warm ocean water and accelerate melting from below. Researchers focused on the Fimbulisen Ice Shelf in East Antarctica and found that this process may make even cold regions more vulnerable. The findings suggest current climate models could underestimate future sea level rise.

Perseverance rover finds complex carbon compounds on Mars

NASA’s Perseverance rover has detected large, complex carbon molecules on rocks in Jezero Crater that show patterns resembling ancient microbial activity on Earth.

Faster subsidence in river deltas compounds underestimated sea level rise

Building on March research revealing sea levels underestimated by nearly a foot in many coastal areas—affecting 80 million people below sea level—a new study maps accelerated land subsidence across 40 major river deltas. Subsidence often exceeds sea level rise tenfold, heightening flood risks for megacities from Shanghai to Jakarta.
