This sure looks like the movements of a glacier across ancient Mars
It is a scientific certainty that Mars was once a much different place, with a denser atmosphere, warmer temperatures, and where water once flowed. Evidence of this past is preserved in countless surface features, ranging from river channels and allu.....»»
Astronomers race to capture image of exoplanet near star
Planet AF Lep b is a world of firsts. In 2023, it was the lowest-mass planet outside our solar system to be directly observed and have its mass measured using astrometry. This is a technique that charts the subtle movements of a host star over many y.....»»

Perseverance team revives SHERLOC instrument to help with Jezero crater discovery
In January 2024, the SHERLOC instrument aboard NASA's Mars 2020 Perseverance rover encountered a significant issue. A fault in the instrument's motor caused the dust cover and autofocus mechanism to become inoperative, putting the rover's SHERLOC Ram.....»»
Physicists and psychologists track social phases in human movement
Observations of preschool children in classrooms and playgrounds have uncovered new social phases in human movement. Employing ultra-wideband radio frequency identification (UWB-RFID) technology allows for the precise tracking of children's movements.....»»
Curiosity rover provides new insights into how Mars became uninhabitable
NASA's Curiosity rover, currently exploring Gale crater on Mars, is providing new details about how the ancient Martian climate went from potentially suitable for life—with evidence for widespread liquid water on the surface—to a surface that is.....»»
Nuclear rockets could travel to Mars in half the time, but designing the reactors that would power them isn"t easy
NASA plans to send crewed missions to Mars over the next decade—but the 140 million-mile (225 million-kilometer) journey to the red planet could take several months to years round trip......»»

Scientists offer a detailed look at the skeleton of an ancient predator that thrived in extreme conditions
Imagine a world on the brink of collapse: volcanic eruptions spewing toxic gases, oceans turning acidic, and up to 90% of Earth's species vanishing in the blink of an eye. This was the reality at the end of the Permian Period, around 252 million year.....»»
2-billion-year-old rock could help understand very early life on Earth and the hunt for evidence of life on Mars
Pockets of microbes have been found living within a sealed fracture in a 2-billion-year-old rock. The rock was excavated from the Bushveld Igneous Complex in South Africa, an area known for its rich ore deposits. This is the oldest example of living.....»»
Centuries ago, the Maya storm god Huracán taught that when we damage nature, we damage ourselves
The ancient Maya believed that everything in the universe, from the natural world to everyday experiences, was part of a single, powerful spiritual force. They were not polytheists who worshipped distinct gods but pantheists who believed that various.....»»
Ancient protein structure may have enabled early molecular evolution and diversification
In a finding that offers fresh insights into the early evolution of life on Earth, two RIKEN biologists have conducted lab experiments that have revealed a previously unknown protein fold, which is completely absent in modern proteins......»»
Study traces wild cat eye color diversity to ancient ancestor
Fans of Clementine, the cat who recently captivated TikTok with her rare eye color, should take note. The piercing golden gaze of cheetahs, the striking blue stare of snow leopards, and the luminous green glare of leopards are all traits that can be.....»»
