A recent study shows that the Earth’s water could come directly from the oxygen and hydrogen present in the rocks that formed it, and not from a late supply by asteroids.
The presence of water on the Earth’s surface is the result of a subtle balance between different mechanisms in the atmosphere and below the surface.
If all of humanity was wiped out tomorrow, it’s estimated that the natural world would take at least five million years to recover from the damage humans have done to the world.
Research shows that when people feel insecure and anxious they become more concerned with identity values such as nationalism, status and success.
It’s all to do with the light from the Sun and a blanket of air wrapped around Earth called the ‘atmosphere’.
The study of neutrinos produced within the Earth’s interior provides a better understanding of the radioactivity of our planet.
A severe climate change event on Venus may have transformed an Earth-like climate to the current uninhabitable-to-humans state.
Paleontologists have discovered fossil remains belonging to an enormous ‘toothed’ bird that lived for a period of about 60 million years after dinosaurs.
The Earth’s magnetic field was most likely weaker when life evolved on our planet than it is today.
The clouds of Venus may harbour alien life. But where else?
Despite clear air as a result of the pandemic reducing human activities, our emissions still soar.
Martian meteorites allow scientists here on Earth to decode that planet’s geology, more than a decade before the first missions are scheduled to bring rocks back home from Mars.
From the Moon’s size to the first calculator, the ancients made some jawdropping discoveries without modern technology.
The Earth and the Moon were long thought to be virtually identical in composition. Now we know they are not.
These scientists identified the five most severe crises the planet faces in a new report, Our Future on Earth 2020.
Many people are still upset that Pluto was demoted from being a planet. But definitions of various celestial objects are fairly fluid. So whether it is an asteroid or moon or planet is up for debate.
The first Martian might just be a human being.
Kepler-452b is sometimes called ‘Earth 2.0’, but there’s a lot we still don’t know about it.
Of all the planets in the solar system, there’s a reason we call Earth home. It’s made of just the right stuff. It’s not too small, or too big, or too hot or too cold. It’s just right.
