Curiosity Rover Detected Methane on Mars in 2013, a New Analysis Confirms

NASA’s Curiosity rover shook the science community six years ago when it apparently detected traces of methane—an important chemical linked to life—on Mars. Researchers failed to confirm these results in the years that followed, but that’s now changed thanks to a re-analysis of data collected from orbit. Read More >>

NASA’s Mars-Bound Helicopter Passes Critical Flight Tests In Extreme Conditions

Six-wheeled rovers on Mars are great, but imagine a helicopter flying through the thin Martian air. Darting from location to location, the craft would give us a bird’s eye view of the Red Planet. To test the feasibility of this idea, NASA will be sending a rotary-wing aircraft to Mars and, as recently concluded flight tests have shown, this tiny chopper is officially ready for prime time.

Saturn’s Flying-Saucer ‘Ring Moons’ May Have Formed From a Giant Impact

During the final days of the legendary Cassini mission, the NASA spacecraft performed a series of ring-skimming orbits around Saturn, snapping unprecedented images of the gas giant’s enigmatic ring moons. These photos and other data have now been analysed by astronomers, shedding new light on these elusive objects and the origin of Saturn’s majestic rings. Read More >>

Wildly Spinning Asteroid Caught In the Throes of Self-Destruction

With its long, bright tail, this object bears an uncanny resemblance to a comet, but it’s actually an active asteroid. New observations suggest the asteroid is spinning so quickly that it’s starting to break down and crumble, in what is a relatively rare cosmological phenomenon. Read More >>

Unopened Lunar Samples from Apollo Missions Will Finally be Studied

During the Apollo missions, NASA smartly set aside some lunar materials knowing future scientists would likely be better equipped to analyse them. Now, nearly 50 years later, the space agency is giving a select group of researchers the extraordinary opportunity to study these unopened and untarnished samples. Read More >>

The Enduring Mystery of the Martian ‘Blueberries’ Discovered by Opportunity Rover

NASA has officially called an end to the historic Opportunity rover mission, ending a spectacular, 14-year adventure on the Red Planet. One of the rover’s most intriguing discoveries, however, came just two months after it landed, when it stumbled upon tiny objects bearing a startling resemblance to blueberries — the nature of which still divides scientists today.

Curiosity Rover Says Goodbye to Its Home of a Year With Superb Panoramic

The twisting terrain of Vera Rubin Ridge on Mars has been home to NASA’s Curiosity for over a year, but it’s time for the rover to move on. As a final gesture before trekking toward a nearby region rich in clay, the probe captured a stunning 360-degree panorama of its final worksite at the ridge. Read More >>

What’s the Worst Planet?

The best planet is Earth, objectively, and I only say that because I live there. Other than Earth, you might find fans of Jupiter, Mars, and even Mercury. But what about planets that absolutely stink? Are there planets which aren’t and will never be habitable, have absolutely nothing interesting to study, or just induce ire for no discernible reason?

The Frequency of Asteroid Impacts Jumped Just Before the Dinosaur Age, New Research Suggests  

By comparing the age of impact craters on the Moon to those on Earth, researchers say they have discovered a surge in the rate of asteroid strikes starting around 290 million years ago—a finding that runs contrary to scientific convention. And indeed, not everyone is convinced by the evidence. Read More >>
