While most people searching for signs of alien life these days might have their eyes on the exoplanet K2-18b, one team of researchers is keeping their sights a little closer to home. Texas A&M researcher Michael Tice and a team of international scientists have revealed new clues about Mars’ potential to have supported life, thanks to data collected by NASA’s Perseverance rover. Since 2021, Perseverance has been exploring Mars’ Jezero Crater, using its mobile laboratory to support the work of scientists around the world. Tice and his team, in particular,…

The European Space Agency (ESA) just released some new snapshots from its Mars Express orbiter that detail the dynamic terrain of the Red Planet’s Acheron Fossae region. One of the photos shows trough-like features called “grabens,” which run about 500 miles (800 kilometers), or roughly the length of Germany. They were shaped from ancient volcanic activity that twisted the surface of Mars almost four billion years ago. Flowing lava from the nearby Alba Mons volcano (not pictured) is likely responsible for the smooth region in the bottom center of the…

María Rosa Pino Otín is a Professor and researcher of Microbiology, Universidad San Jorge We often forget how wonderful it is that life exists, and what a special and unique phenomenon it is. As far as we know, ours is the only planet capable of supporting life, and it seems to have arisen in the form of something like today’s single-celled prokaryotic organisms. However, scientists have not given up hope…

Back in 1976, the dual NASA Viking landers came to full stop on the Red Planet. Their life detection experimental findings still reverberate within the scientific community – fueling the on-going discussion on a key question: Is there life on Mars? Fast forward to today, a new paper tackles and reconsiders the results of the Viking Biology experiments. Perchlorate finding The most significant change since those 1970’s experiments were conducted was the discovery of high levels of perchlorate on Mars. Perchlorate, plus abiotic oxidants, explains the Viking results and there…

Recordings of Martian earthquakes, or “marsquakes,” collected by a robot on the Red Planet may have finally solved a 50-year-old mystery: why one half of Mars is so drastically different from the other. Since the 1970s, researchers have known that Mars is split into two main areas. The northern lowlands cover around two-thirds of the planet’s northern hemisphere, while the southern highlands cover the rest of the planet and have an average elevation roughly 3 miles (5 kilometers) higher than that of the northern lowlands. Mars’ crust, which sits on…

New research suggests that temperatures on ancient Mars may have fluctuated between hot and cold periods through a relatively short period during its lifetime of billions of years. But these hot and cold spells may have been detrimental to life if it existed on the Red Planet. Mars may be a dry and arid planet today, but scientists know that Earth’s neighbor was much wetter and much more like our planet in its ancient past. These new findings from a team of researchers at the Harvard John A. Paulson School…

Thousands of hills and mounds on Mars have been found to contain layers of clay minerals, which formed when running water interacted with the rocks during a period when Mars’ northern reaches were flooded. “This research shows us that Mars’ climate was dramatically different in the distant past,” Joe McNeil of the Natural History Museum in London said in a statement. “The mounds are rich in clay minerals, meaning liquid water must have been present at the surface in large quantities nearly four billion years ago.” Mars is a planet…

Instead of chilled glasses and champagne bubbles to ring in the New Year, how about gassy geysers and frosty avalanches? That’s exactly what you can expect as the Martian New Year begins on the Red Planet with the onset of spring across its Northern Hemisphere. The term “walking in a winter wonderland” on Mars consists more like sprinting across the surface, having to dodge the crash of cliffsides and explosions of carbon dioxide. Unlike our northern hemisphere on Earth, on the Red Planet, the new year starts off with the…
