Wait, What? NASA Found Signs of Ancient Alien Life on Mars

NASA released a significant update from the Perseverance Mars rover on Sept. 10, focusing on a particularly juicy tidbit for those watching from home: A small rock sample called Sapphire Canyon showed signs of potential biosignatures, or ancient alien life that may have once grown on Mars. That's possible because of the unique location where Perseverance located the sample in July 2024. It came from a rock named Cheyava Falls. This particular rock is in Jezero Crater, home to an ancient dry riv

NASA found intriguing rocks on Mars, so where does that leave Mars Sample Return?

NASA's interim administrator Sean Duffy was fired up on Wednesday when he joined a teleconference to talk about new scientific findings that concerned the potential for life to have once existed on Mars. "This is exciting news," said Duffy about an arrow-shaped rock on Mars found by NASA's Perseverance rover. The rock contained chemical signatures and structures that could have been formed by ancient microbial life. The findings were intriguing, but not conclusive. Further study of the rocks in

NASA Says This Martian Rock Holds Potential Signs of Life. Here’s What Must Happen Next

For four years, NASA’s Perseverance rover has searched for possible signs of ancient life on the surface of Mars. It has found myriad interesting features in its travels, including a rock with strange spots, discovered inside Mars’ Jezero Crater. Dubbed “Cheyava Falls,” the 2024 discovery immediately caught the attention of scientists on Earth, as its spots indicated it may hold a potential biosignature—a sign of life. The rover went to work. The bot analyzed the rock’s composition and surface

NASA found clues of life on Mars, but budget cuts threaten future missions

An exciting discovery on Mars is being overshadowed by turmoil at NASA, with budget cuts threatening to destroy a scientific legacy that has been built over decades. Yesterday, the agency shared a finding, published in Nature, of potential biosignatures identified by the Mars Perseverance rover in a 3.5 billion-year-old rock. “This very well could be the clearest sign of life that we’ve ever found on Mars,” said Transportation Secretary and Acting NASA Administrator Sean Duffy in a press confe

NASA Says Its Mars Rover Has Detected Possible Signs of Life on the Red Planet

NASA has announced that its Perseverance Mars rover spotted "potential biosignatures" in an ancient dry riverbed last year. Samples collected from a rock dubbed "Cheyava Falls" contain a structure that hints at the possibility of having a biological origin, according to the space agency, but more research needs to be completed to draw any conclusions about the presence of life on the Red Planet. "The identification of a potential biosignature on the Red Planet is a groundbreaking discovery, an

NASA's Perseverance rover finds potential signs of ancient life on Mars

NASA just announced that its Perseverance rover recently found some promising signs of ancient life on Mars. The rover obtained a sample of rock formed billions of years ago from sediment and there are biomarkers indicating the potential presence of microbes once upon a time. Basically, the rocks contain minerals that typically form as a result of a chemical reaction between mud and organic matter. That doesn't necessarily mean that Mars once had life, as the minerals can form due to nonbiologi

How to make metals from Martian dirt

27 August 2025 3 min read Key points Swinburne and CSIRO researchers are investigating ways to produce native metals using materials found on Mars. Martian settlements will require large amounts of metal that are difficult to ship from Earth. The team have successfully produced iron using regolith simulant that mimics what is available on the Red Planet. The idea of building settlements on Mars is a popular goal of billionaires, space agencies and interplanetary enthusiasts. But constructio

Four Telescopes Confirm There's Something Deeply Strange About the Mysterious Object Headed Into the Solar System

By definition, scientists don't know what to expect as they inspect the interstellar object 3I/ATLAS, since it's only the third object detected from beyond the solar system in human history. But the surprises just keep coming. The mysterious entity, which was first spotted hurtling towards the Sun from far beyond in early July, has fascinated researchers ever since. As Science Alert points out, a quartet of powerful telescopes — NASA's Hubble, SPHEREx, Transiting Exoplanet Survey Satellite (TES

The Robot Vacuum’s Next Humble Trick: Climbing Stairs

Stair-climbing robot vacuums are actually about to be a reality, sort of. That’s courtesy of a little baby trend at IFA 2025 of robot vacuums slipping into something more climbable—a little caddy that carries them upstairs when it’s time to move floors, then waits to carry them back down when they’re done. The first one we encountered was the Eufy MarsWalker. Then, it turned out that Dreame had one, too, using almost the exact same approach, only it’s weirdly much scarier-looking. Both have a s

NASA Finds Evidence That Mars Devoured Huge Chunks of Other Planets

The Red Planet has a bloody history. Newly examined data from NASA's retired InSight lander suggest that there may be giant chunks of rocky material deep inside the mantle of Mars, which were lodged there after a barrage of massive objects slammed into its surface some 4.5 billion years ago. Some of these smithereens are so large, the researchers say, that they're effectively protoplanets — moon-sized objects in the early stages of becoming a planet proper. In other words: Mars could be stuffe

Eufy's MarsWalker allows its robot vacuums to climb stairs

Eufy just introduced a couple of new devices at the IFA conference in Germany, including something called the MarsWalker. This little doodad picks up robot vacuums and carries them up and down stairs. That's pretty neat, considering stairs are the bane of any robovac's existence. The company says the MarsWalker automatically recognizes common stair types, including straight, L-shaped and U-shaped. It transports the vacuum between floors and drops it off at the base station when needed. Eufy boa

Mysterious Object Headed Toward Mars

Incoming! Earlier this year, astronomers spotted a mysterious interstellar visitor, widely believed to be a comet, screaming into our solar system. With the help of NASA's James Webb Space Telescope, astronomers recently got a closer look at the object, dubbed 3I/ATLAS, that revealed an unexpectedly high ratio of carbon dioxide to water for a comet, as well as a highly irradiated ice core. Ever since astronomers spotted the object, Harvard astronomer Avi Loeb has suggested the tantalizing pos
