The path of comet 3I/ATLAS through the solar system has been predicted with an accuracy 10 times greater than previous ...

Scientists suspect iron meteorites might be able to resist erosion on Mars, which may explain why some appear perched on flat ground rather than embedded in craters. In other cases, a crater may have ...

FAYETTEVILLE, Ark. — Researchers at the University of Arkansas have recently discovered geological formations on Mars that suggest the past presence of large rivers that once flowed into an ocean.

The Martian polar vortex exhibits significantly lower temperatures (approximately 40°C colder) within its core compared to the surrounding atmosphere, a phenomenon observed through the use of the ...

Scientists recently discovered evidence that could point to ancient life on Mars. NASA's Science Mission Directorate says it's "the closest we've actually come to discovering ancient life on Mars." ...

50 years ago, NASA sent two spacecraft—Viking 1 and Viking 2—to search for life on Mars. These groundbreaking missions carried biology labs onboard and conducted the first-ever experiments directly on ...

If it pans out, it’s a big deal. Scientists at the National Aeronautics and Space Administration caused a stir last week when they announced they had found potential signs of ancient microbial life on ...

Did NASA really just announce the existence of aliens? Not quite. Here's what the new evidence uncovered on Mars really means. NASA's Perseverance rover has uncovered what could be evidence that Mars ...

"The idea was for our payload to get us just up to the potential biosignature designation and have the rest of the story told by instruments here on Earth." A potentially huge discovery by NASA's ...

The rover’s science instruments found that the formation’s sedimentary rocks are composed of clay and silt, which, on Earth, are excellent preservers of past microbial life. The findings were made ...
