3.5 billion-year-old rock structures are one of the oldest signs of life on Earth

Layered rocks in Western Australia are some of Earth’s earliest known life, according to a new study.  The fossils in question are stromatolites, layered rocks that are formed by the excretions of photosynthetic microbes. The oldest stromatolites that scientists agree were made by living organisms date back 3.43 billion years, but there are older specimens, […]

New ‘oasis of life’ filled with ravenous sharks is found hiding beneath Maldives ocean

Deep-sea divers have discovered a completely new ecosystem 1,640 feet (500 meters) beneath the water’s surface in the Indian Ocean, and it’s filled with hungry sharks. Scientists described the region — named the “Trapping Zone” and located near the Maldives’ deep-sea volcano Satho Rahaa — as an “oasis of life” in a “very large ocean […]

First Martian life likely broke the planet with climate change, made themselves extinct

Ancient microbial life on Mars could have destroyed the planet’s atmosphere through climate change, which ultimately led to its extinction, new research has suggested. The new theory comes from a climate modeling study that simulated hydrogen-consuming, methane-producing microbes living on Mars roughly 3.7 billion years ago. At the time, atmospheric conditions were similar to those […]
