The researchers also assume that a hypothetical extraterrestrial civilization would rely exclusively on solar energy. However, if other sources of energy are used, such as nuclear fusion, it would reduce the silicon technosignature, making the civilization even harder to detect. The study further assumes that the civilization’s population stabilizes at some point. If this doesn’t … Read more
The six-wheeled geologist found a fascinating rock that has some indications it may have hosted microbial life billions of years ago, but further research is needed. A vein-filled rock is catching the eye of the science team of NASA’s Perseverance rover. Nicknamed “Cheyava Falls” by the team, the arrowhead-shaped rock contains fascinating traits that may … Read more
Early analysis of the asteroid Bennu sample returned by NASA’s OSIRIS-REx mission has revealed dust rich in carbon, nitrogen, and organic compounds, all of which are essential components for life as we know it. Dominated by clay minerals, particularly serpentine, the sample mirrors the type of rock found at mid-ocean ridges on Earth. The magnesium-sodium … Read more
At the agency’s Jet Propulsion Laboratory, interns from Cal State LA are learning key skills studying the origins of life. What does wastewater management in Los Angeles have to do with the search for life on Mars? Eduardo Martinez certainly didn’t make the connection when he was pursuing a master’s in civil engineering. Not at … Read more
A cutting-edge tool to view planets outside our solar system has passed two key tests ahead of its launch as part of the agency’s Roman Space Telescope by 2027. The Coronagraph Instrument on NASA’s Nancy Grace Roman Space Telescope will demonstrate new technologies that could vastly increase the number of planets outside our solar system … Read more
A study zooms in on data that NASA’s Cassini gathered at Saturn’s icy moon and finds evidence of a key ingredient for life and a supercharged source of energy to fuel it. Scientists have known that the giant plume of ice grains and water vapor spewing from Saturn’s moon Enceladus is rich with organic compounds, … Read more
WASHINGTON: Scientists have identified 24 planets outside our solar system that they say may have conditions more suitable for life than the Earth. The study, published in the journal Astrobiology, details characteristics of potential “superhabitable” planets, that include those that are older, a little larger, slightly warmer and possibly wetter than Earth. The researchers from … Read more
