Who hasn’t looked into the sky and wondered if there’s life out there, somewhere, looking back at us? Is it possible there’s alien life closer to home — within the bounds of our solar system? The short answer is yes, there are several places researchers are looking for signs of life within our solar system, … Read more
Mars was a rainier, wetter place than planetary scientists previously thought, according to a new study of ancient, inverted river channels that span more than 9,000 miles (14,484 kilometers) in the Red Planet’s southern Noachis Terra region. “Our work is a new piece of evidence that suggests that Mars was once a much more complex … Read more
Tremendous tilts of Mars’ rotational axis during the past 20 million years may have dried out the planet, according to a new study. The findings may help solve the mystery of how Mars, which once contained lakes, rivers and possibly oceans, lost its water. Dry, dust-filled deserts cover much of Mars’ surface today. Astronomers think … Read more
Despite being known as the Red Planet, Mars shows off its swirling yellows, oranges and browns in a new satellite photo from the European Space Agency (ESA). The Earth-toned surface also reveals an impact crater and four sneaky dust devils making their way across the region. The Rothko-like image was taken by a high-resolution camera … Read more
People from cultures across the world have been looking at Mars since ancient times. Because it appears reddish, it has often been called the red planet. The English name for the planet comes from the Romans, who named it after their god of war because its color reminded them of blood. In reality, the reddish … Read more
The concept of terraforming Mars — transforming the planet’s climate to support life as we know it — has long belonged to the realm of science fiction. But a new study argues that it’s time to take the idea seriously. “Thirty years ago, terraforming Mars wasn’t just hard — it was impossible,” said Erika DeBenedictis, … Read more
After nearly a decade in orbit, NASA’s MAVEN spacecraft has, for the first time, directly observed the process that scientists had long suspected was responsible for stripping Mars of its atmosphere. The findings, published May 28 in the journal Science Advances, could help answer a longstanding question about how Mars transformed from a potentially habitable … Read more
There might be a hidden ocean’s worth of liquid water below the surface of Mars, seismic evidence suggests. According to a new paper published April 25 in the journal National Science Review, recordings of seismic waves from deep within the Red Planet indicate that a layer of liquid water may be lurking in the Martian … Read more
NASA’s Curiosity rover has found some of the best evidence yet that ancient life may have existed on Mars — and an answer for what could have wiped it out. When drilling into rocks on Mount Sharp, the central peak of the Red Planet’s Gale Crater, the rover found evidence of siderite, an iron carbonate … Read more
We may have been wrong about how Mars got its characteristic red hue, a new study reveals. The Red Planet owes its ruddy complexion to rusted iron minerals, dispersed across billions of years by winds, throughout the planet’s dust. Past spacecraft observations of Martian dust led scientists to believe that this rust emerged in dry … Read more
