The recent detection of potential signs of ancient microbial life on Mars by NASA’s Perseverance rover has sparked renewed interest in the planet’s habitability. The rover’s analysis of a Martian rock ...

Spaceflight rewires the human body. Muscles shrink, bones thin and fluids shift towards the brain – but these changes may ...

A new analysis of chemical signatures measured by NASA's Curiosity Rover gives a peek at Mars's past to a time some 3.7 ...

For years, scientists have puzzled over the sinuous grooves found etched across the sand dunes of Mars. These features, ...

Abstract: Nowadays, serious lateral temperature gradient across the chip surface can significantly reduce the lifetime of the power semiconductor devices. Currently, the primary methods for extracting ...

Buried underground near the surface, frozen regions of Mars could have tiny hidden channels full of liquid water, which could be a habitable environment for microscopic organisms ...

Because oxygen-bearing sulfate minerals trap and preserve signals from Earth's atmosphere, scientists closely study how they ...

Scientists simulated the conditions of Mars in a lab to observe how blocks of carbon dioxide "dug" their way through the ...

A NASA study shows bacteria fragments can survive 50 million years in Martian ice. Pure ice, not rock, could hold clues to ...

Mars’ north polar vortex locks its atmosphere in extreme cold and darkness, freezing out water vapor and triggering a ...

Blocks of frozen carbon dioxide sliding down Martian dunes may have carved the planet’s strange gullies, mimicking the work ...

Could ancient microbes still be hiding on Mars—preserved for millions of years in ice? A new NASA and Penn State study ...
