Scientists have long relied on chemical traces locked inside ancient rocks to piece together the story of early life. Fossils from the deepest reaches of Earth's history are rare, often fragmentary and difficult to interpret.

On July 8, about 99 per cent of the world's 8.2 billion people experienced daylight or twilight at the same time. Earth's tilt and human geography combined for a fleeting global moment that lasted barely a minute.

Long before dinosaurs walked the Earth, and long before animals or plants fully spread across dry land, strange marine creatures were already thriving in the planet's earliest reefs. Among them were crinoids -- ancient relatives of starfish that looked like delicate sea flowers anchored to the ocean floor.

Researchers studying ancient rocks from Western Australia's Pilbara Craton found evidence that water was moving deep into Earth's interior more than 3 billion years ago. The study suggests this early recycling helped drive magma formation and linked the surface with the deep mantle far earlier than thought.

Stardust Solutions develops the particle that reflects sunlight, and also studies how it will be dispersed into the atmosphere and how it will be monitored if it turns harmful.

Discover when life on Earth may end, with estimates ranging from 1.68 to 1.87 billion years due to climate changes.

A two-week expedition off Brazil's coast uncovered 31 previously unknown marine species, highlighting just how little is known about Earth's largest ecosystem.

Beneath every forest, grassland and crop field lies a hidden living network that few people ever see. Invisible to the naked eye, microscopic fungi weave through the soil, connecting plant roots in an intricate web that helps sustain life on Earth.

A controversial proposal to cool off the planet by injecting sulfur into the upper atmosphere has been suggested. This proposal, however, could cause unexpected consequences for air travel, as scientists have found that some of the commercial aeroplane passengers and crew members might get exposed to elevated levels of sulfuric acid if the aircraft fly through areas where climate-cooling aerosols have been released.

Antarctica may feel far removed from everyday life, but new research suggests the icy continent could have a bigger influence on global warming than scientists once believed. A recent study by European Geosciences Union (EGU) points to a stronger-than-expected connection between Antarctic sea ice, cloud cover, and the way Earth stores heat, raising fresh concerns about how quickly the planet could warm in the years ahead.
