Life may have flourished on Earth far earlier than anyone expected. Scientists have taken a closer look at some of our planets oldest rocks and have found that 3.2 billion years ago, life already pulling nitrogen out of the air and converting it into a form that could support larger communities.
The climate is changing across the globe. Now, scientists have found that Ecuador is also suffering. They've studied three remote lakes and have discovered that tropical high mountain lakes are vulnerable to warming temperatures.
Most people know that our planet Earth has a core; but did you know that the core has a core? Seismic waves are helping scientists plumb the depths of our planet and have shown that the Earth actually has an inner core.
Water-filled micropores in hot rock may have been the nurseries in which life on Earth began. Scientists have found that the temperature gradients in these pore systems actually promote the cyclical replication and emergence of nucleic acids.
Astronomers have spotted an ancient, sun-like star with orbiting planets in a system that dates back to the dawn of the galaxy. The system is the oldest to be discovered by far with Earth-sized planets, and proves that such planets formed throughout the history of the universe.
Human activity may have compromised the planet. Scientists have found that nearly half of the processes that are crucial to maintaining the stability of Earth may be on the verge of swinging dangerously out of balance.
Scientists are getting the earliest look yet at Earth's ancient atmosphere. Chemical analysis of some of the world's oldest rocks has revealed a record of our planet's atmosphere four billion years ago.
Astronomers have discovered eight new planets in the "Goldilocks" zone of their stars, orbiting at a distance where it's neither too hot nor too cold and where liquid water can exist on the planet's surface.
How to assemble Earth: Take elements, stir, and dash with water delivered by asteroids. Scientists are taking a closer look at how Earth-like planets are made in order to continue their hunt for exoplanets that have the likeliest chance at supporting life.
Scientists have found out that oceans on super-Earths, once established, can actually last for billions of years, which may explain a bit more about our own planet.
Earth may be mostly covered by water, but where did it first come from? Scientists have long wondered whether water was created by our planet, or whether it arrived via icy comets. Now, they may have their answer.
Where should astronomers look for life on other planets? That's a good question. There are billions and billions of stars in the sky, so narrowing down the search is crucial for success. Now, scientists may have discovered where, and when, infant Earths are most likely to be found.
