While the early climate of Mars remains an open question, a new study suggests that its atmosphere may have been hospitable to life due to volcanic activity that emitted sulfur gases that contributed ...

Earth has kept a habitable climate for >3.5 billion years (Gyr). By contrast, Mars has lost surface habitability over time, a contrast that demands explanation. The main climate-regulating greenhouse ...

Billions of years ago, Mars may not have been the frozen desert we see today. New simulations suggest that volcanic eruptions pumped out reactive sulfur gases, creating greenhouse effects strong ...

Mars has always been a curious planet, often overshadowed by its larger neighbors, but recent research suggests that the Red Planet plays an unexpected role in shaping Earth’s climate. According to a ...

Mars, the enigmatic Red Planet, has long captivated humanity with its stark, seemingly barren landscape. Today, it’s a cold, dry world – a shadow of its once-vibrant past. But what if this desolate ...

Terraforming Mars has long captured the imagination but has received surprisingly little rigorous study. Progress in Mars science, climate science, launch capabilities and bioscience motivates a fresh ...

Researchers are creating advanced simulations that will provide a deeper understanding of Mars's climatic history and help to determine whether it was once able to sustain life. An international team ...

Mars’s Coloe Fossae reveals a landscape shaped by ancient ice ages, with deep valleys, cratered terrain, and frozen debris flows preserved from a time when the planet’s climate dramatically shifted.

Just north of Mars’ equator lies a 45 km (28 mi) wide impact crater known as Jezero Crater. Scientists believe this location ...

Sulfur crystals found inside a rock after NASA’s Curiosity Mars rover happened to drive over it and crush it on May 30, 2024. This discovery supports new research led by scientists at The University ...
