Sebuah lembah luas di Mars menawarkan bukti baru bahwa planet tersebut pernah memiliki badan air yang besar. Shalbatana Vallis membentang sekitar 1.300 kilometer di dekat khatulistiwa dan menunjukkan tanda-tanda banjir air tanah yang dahsyat dari miliaran tahun yang lalu.

Pesawat ruang angkasa Mars Express milik European Space Agency menangkap citra terbaru dari bagian utara lembah tersebut. Tampilan ini menyoroti saluran-saluran dalam yang terbentuk oleh banjir purba, medan yang runtuh, dan endapan abu vulkanik. Saluran utamanya berukuran lebar sekitar 10 kilometer dan memiliki kedalaman hingga 500 meter di beberapa titik.

Study indicates ancient Mars was warm and wet

A recent analysis of clay pebbles from Mars' Jezero crater suggests the planet experienced a warm and wet climate during the Noachian epoch billions of years ago. This finding challenges the prevailing view of a cold and icy environment at that time. The evidence comes from NASA's Perseverance rover and points to conditions potentially suitable for life.

Researchers from New York University Abu Dhabi have uncovered evidence that water flowed beneath Mars' surface billions of years ago, potentially sustaining habitable conditions longer than previously thought. Analysis of ancient sand dunes in Gale Crater, studied by NASA's Curiosity rover, shows minerals left by groundwater. These findings suggest subsurface environments could have protected microbial life after surface water vanished.

Scientists map deep mantle deformation linked to ancient tectonic slabs

Researchers have created the first global map showing how Earth's deepest mantle is deformed, primarily in regions where ancient subducted tectonic slabs reside. Using over 16 million seismograms, the team confirmed patterns predicted by geodynamic models. The findings, published in The Seismic Record, offer new insights into mantle flow near the core-mantle boundary.

Moon's contraction uncovers new tectonic ridges

Scientists have mapped over a thousand small mare ridges on the Moon, revealing ongoing contraction and potential seismic activity. These features, among the youngest on the lunar surface, form in the dark maria plains and share origins with known moonquake sources. The findings could guide safer landing sites for future missions like Artemis.

Meteor impacts may have sparked life on early Earth

Scientists suggest that asteroid impacts created hot, chemical-rich environments that could have kick-started life on Earth. A new review led by recent Rutgers graduate Shea Cinquemani highlights impact-generated hydrothermal systems as potential cradles for life's building blocks. These systems may have persisted for thousands of years, providing ideal conditions for early biology.
