The origins of how life on Earth arose remains a deep existential and scientific mystery. It’s long been theorized that our planet’s plentiful oceans could hold key to the secret. A new study ...

A recent study led by NASA has revealed a surprising connection between Earth’s magnetic field and the oxygen levels that sustain life. According to the new research, the ebb and flow of Earth’s ...

When scorching columns of rock, known as deep mantle plumes, first rise from depths of nearly 3,000 kilometers (almost 2,000 ...

Without enough liquid water on the surface, a planet's atmosphere can become choked with carbon dioxide, raising temperatures ...

Ancient oceans with phosphorus-rich waters may have supported some of Earth’s earliest microbial life, according to a new ...

“We find that both exhibit strong linearly increasing trends, coupled with a large surge in magnitude between 330 and 220 million years ago,” the authors wrote. “Our findings suggest unexpected strong ...

Lightning strikes in a stock photo. A new study says lightning may have jump-started early life on Earth by converting atmospheric elements into vital building blocks.

Earth is a bustling planet powered by a remarkable array of microorganisms that play key roles in sustaining life. Though invisible to the naked eye, these tiny but mighty beings are indispensable ...

Alien life might not be based on carbon, which forms the backbone of all life’s essential molecules – at least here on Earth. It might not even need a planet to survive.

Just like today, early life on Earth was therefore dependent on nitrogen fixation by microbes. In other words, on their conversion of atmospheric nitrogen into nitrogen compounds that living ...

NASA scientists have discovered an electric field encompassing Earth’s atmosphere that is as “fundamental” as gravity — and could even give clues about possible life on other planets.

Ryugu is a 0.55 mile-long rock traveling around the sun in an orbit similar to Earth’s. It is a so-called C-type asteroid, a species of space rubble that is heavy in carbon and represents about ...
