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.
