Researchers are exploring extreme cave environments on Earth to help locate life on Mars, icy moons, and beyond. These underground worlds could be the key to discovering we're not alone in the universe.
Researchers have identified the 45 exoplanets with the best chance of hosting alien life, creating a roadmap for humanity's search beyond Earth. The study points astronomers toward smaller, cooler stars where rocky worlds in the habitable zone are easier to spot.
Astronomers have narrowed down 6,000 known planets to just 45 rocky worlds where alien life might exist. Some of the most promising candidates are only dozens of light-years away.
Scientists discovered that moons orbiting starless planets drifting through space could stay warm enough for life for billions of years. A thick hydrogen atmosphere might trap heat and support liquid water even in the darkest corners of our galaxy.
New research suggests space weather might be scrambling alien radio signals before they reach us, offering hope that extraterrestrial civilizations could be out there trying to communicate. Scientists at the SETI Institute discovered how stellar activity disrupts transmissions, and they're already working on ways to detect these hidden messages.
Scientists at the SETI Institute discovered that cosmic storms might be scrambling radio signals from extraterrestrial civilizations, making them impossible for us to detect. The finding offers a hopeful new explanation for why we haven't heard from alien life yet.
Scientists created a simple chemistry test that can identify alien life with 95% accuracy, even if it's unlike anything on Earth. The breakthrough could help future missions to Mars and Saturn's moons find extraterrestrial organisms.
Scientists discovered Earth formed under incredibly precise chemical conditions that allowed it to retain the exact elements needed for life. Most planets miss this narrow sweet spot, making our world a fortunate cosmic exception.
Scientists discovered Earth formed under incredibly precise chemical conditions that let it keep phosphorus and nitrogen, two elements essential for life. Most planets miss this narrow sweet spot, making our world a fortunate exception in the universe.
Scientists discovered ammonia compounds on Jupiter's moon Europa by reanalyzing 1997 spacecraft data, suggesting the icy moon's hidden ocean could support life. The compounds appeared near surface cracks where ocean water likely pushed through from below.
Scientists discovered a partially frozen ocean beneath the ice of Saturn's largest moon, creating conditions that could support life. The slushy mix of ice and liquid water makes this distant world one of the most promising places to search for alien life.
Scientists now have the tools to detect signs of life on planets beyond our solar system by analyzing their atmospheres. New space telescopes launching through 2029 will help us answer one of humanity's oldest questions: are we alone?
Researchers are developing serious scientific methods to detect potential alien technology in our solar system, from studying century-old telescope images to tracking interstellar visitors. The search for extraterrestrial artifacts is moving from science fiction into legitimate scientific inquiry.
A new NASA telescope launched to help scientists solve a major problem blocking our search for life on distant planets. Pandora will work alongside the James Webb Space Telescope to filter out confusing signals from stars and get clearer readings of alien worlds.
