PASADENA, Calif. — Experiments prompted by a 2008 surprise from NASA’s Phoenix Mars Lander suggest that soil examined by NASA’s Viking Mars landers in 1976 may have contained carbon-based chemical building blocks of life. “This doesn’t say anything about the question of whether or not life has existed on Mars, but it could make a […]

After undergoing a major overhaul and upgrades, the Boeing / NASA X-48B Blended Wing Body research aircraft resumed flight tests with a checkout flight Sept. 21 from NASA’s Dryden Flight Research Center at Edwards Air Force Base, Calif. The subscale, manta ray-shaped, remotely piloted airplane, also called a hybrid wing body, is a tool of […]
NASA-Funded Research Discovers Life Built With Toxic Chemical NASA-funded astrobiology research has changed the fundamental knowledge about what comprises all known life on Earth. Researchers conducting tests in the harsh environment of Mono Lake in California have discovered the first known microorganism on Earth able to thrive and reproduce using the toxic chemical arsenic. The […]
A team of NASA-funded researchers has unveiled a new theory that contends planets gained the final portions of their mass from a limited number of large comet or asteroid impacts more than 4.5 billion years ago. These impacts added less than one percent of the planets’ mass. Scientists hope the research not only will provide […]
American Geophysical Union Meeting: Global Eruption Rocks the Sun On August 1, 2010, an entire hemisphere of the sun erupted. Filaments of magnetism snapped and exploded, shock waves raced across the stellar surface, billion-ton clouds of hot gas billowed into space

Dec. 2, 2010: NASA-supported researchers have discovered the first known microorganism on Earth able to thrive and reproduce using the toxic chemical arsenic. The microorganism, which lives in California’s Mono Lake, substitutes arsenic for phosphorus in the backbone of its DNA and other cellular components. “The definition of life has just expanded,” said Ed Weiler, […]
