In 1831, somewhere on Earth's surface a massive volcano opened wide its jaws and belched forth so much ash and smoke that the skies dimmed, cooling the Northern Hemisphere.
If Earth is going to be blown to bits by an asteroid, it'd be nice to have some advance warning and a newly developed equation gives us a better chance of an early heads up.
A team of Swiss geophysicists thinks they have found the answer in Earth's molten iron core which causes tiny alterations affecting the planet's rotation.
It's time to recalibrate the navigation systems on ships, airplanes: the position of the magnetic North Pole is officially being changed, continuing its shift away from Canada and towards Siberia.
A new analysis of the eruption rates of 56,400 Sun-like stars has estimated that the Sun's superflare rate is at the low end of that scale – once every 100 years.
A newly discovered gold ore deposit in China is not just massive—it’s described as "supergiant." Chinese experts claim it could be the largest precious metal deposit in the world.
Hunga Tonga-Hunga Ha'apai, an underwater volcano in the Tongan archipelago, erupted violently on January 15, 2022. According to a new study though, two faraway monitoring stations recorded a seismic wave some 15 minutes earlier.
Today, Antarctica is a huge frozen continent, though it was once temperate enough to be covered in swampy forests. Now, a team of scientists has discovered fossilized tree resin—amber—on the continent for the first time.
Greenhouse gas levels surged to a new record in 2023, committing the planet to rising temperatures for many years to come. CO2 is accumulating in the atmosphere faster than any time experienced during human existence.
Some 3.26 billion years ago a giant rock between 50 and 200 times the size of the Chicxulub dino-killer smacked into our planet. The result of this impact may have churned up nutrients that gave a select few early microbes a boost.
Approximately 41,000 years ago, Earth’s magnetic field briefly reversed during what is known as the Laschamp event. Now scientists has created a sound visualization of this event.
Lightning storms on our planet can dislodge particularly high-energy, or "extra-hot" electrons from the inner radiation belt - a region of space enveloped by charged particles that surround Earth like an inner tube.
The earliest cells likely didn't have membranes to separate and protect their components and chemistry away from a harsh surrounding environment. But they may have made do with rain.
Highly reactive complex molecules finding some sort of stability was a necessary step towards life getting started on Earth.
Our planet will only remain able to provide even the most basic standard of living for everyone in the future if economic systems and technologies are dramatically transformed and critical resources are more fairly used, managed and shared.
