The James Webb Space Telescope detected a promising chemical signal on a distant planet that could point to life, though researchers urge caution. The hunt for life beyond Earth is advancing with better tools and new possibilities.
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.
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.
New climate modeling reveals that complex life on Earth will survive far longer than scientists previously thought. Researchers found that even as our Sun brightens, plants and other life forms have at least 1.3 billion years before conditions become uninhabitable.
After JWST found several barren planets, astronomers aren't giving up. Two new missions launching by 2040 offer real hope for detecting life on distant worlds.
NASA's Hubble Space Telescope has reached an incredible milestone, confirming the existence of more than 6,000 planets beyond our solar system. This astronomical achievement opens new possibilities in humanity's search for life beyond Earth.
New research reveals that plants and complex life on Earth could thrive for 1.8 billion years instead of the previously predicted 1.35 billion years, thanks to certain plants' super-efficient photosynthesis abilities. The discovery also means we might have better odds of finding life on other planets.
Scientists discovered glowing green bacteria thriving in complete darkness inside New Mexico caves, photosynthesizing with invisible light. This breakthrough suggests life could exist in dark environments across the universe we never thought possible.
Scientists discovered towering microbial structures beneath Antarctica's frozen Lake Unter-See that mirror Earth's oldest fossils and might reveal how life survives on icy planets. These ancient life forms create oxygen-rich water under permanent ice, offering hope for finding life beyond Earth.
Scientists discovered Earth stayed habitable only because oxygen levels hit a perfect sweet spot 4.6 billion years ago. Too much or too little oxygen during planet formation, and life-essential elements would have vanished.
Scientists discovered Jupiter's massive gravity acted like a cosmic gatekeeper, shaping how Earth received the nitrogen and phosphorus we needed to become a living world. The finding suggests giant planets might be essential for life across the universe.
Rocky planets up to six times Earth's size could generate powerful magnetic fields from layers of molten rock, not just their cores. This discovery suggests far more alien worlds might protect potential life from deadly cosmic radiation than scientists previously thought.
Every year, Venus and Jupiter appear to nearly touch in our night sky—and scientists say this cosmic dance is actually a sign that Earth's orbit is perfectly arranged for life. Our solar system's rare "flat pizza" shape keeps planets stable and our climate livable.
Scientists discovered 567-million-year-old fossils in Canada's remote mountains that show some of Earth's earliest creatures could move and reproduce sexually. The findings suggest complex life began in the deep ocean before gradually moving to shallow waters.
NASA scientists discovered that Earth's earliest life forms relied on molybdenum over 3 billion years ago, even though the metal was incredibly scarce. This finding rewrites what we know about how life adapts and what alien worlds might need to support it.
Scientists discovered a global network of water trapped underground for up to 2.6 billion years that produces hydrogen and could support entire ecosystems we never knew existed. The finding doubles our estimates of where life might thrive on Earth and offers new hope for discovering life on Mars.
The BBC's groundbreaking nature documentary series Planet Earth turns 20 this year, marking two decades of bringing never-before-seen wildlife moments into our homes. The network just released an hour-long compilation celebrating iconic scenes that changed how we see our world.
Scientists in China discovered 700 fossils that push back the origin of complex life by millions of years. The find suggests the famous "Cambrian Explosion" may have been more of a slow burn than a sudden boom.
Fungi sustain 90% of plant life on Earth, yet only two species are protected in the U.S. Now scientists are winning major awards and launching campaigns to give these invisible ecosystem heroes the recognition they deserve.
