At least two mass extinction events in Earth's history were likely caused by the "devastating" effects of nearby supernova explosions, a new study suggests.
Millions of years ago, our Solar System traveled through a densely populated galactic region and was exposed to increased interstellar dust.
Researchers say the 3.47-billion-year-old meteorite impact crater could help explain how life on Earth began.
Continent-sized structures of mineral protruding from the lower mantle towards Earth's outer core may be contributing to an instability of our planet's magnetic field.
In the new work, Hirose and colleagues at other institutions in Japan and Taiwan propose that the iron core of the Earth formed bonds with helium, allowing the core to act as a reservoir.
This melting has implications for global climate indicators, including sea level rise, ocean warming and viability of marine ecosystems.
New research has demonstrated the precise relationship between past ice ages and each wobble, tilt, and angle of the planet's path, unlocking a new tool for predicting the future fluctuations of our global climate.
Hundreds of millions of years ago, rocks crushed under kilometres of ice injected vital nutrients into Earth's oceans.
Scientists have traced radioactive elements on the seafloor back to the cosmic explosions they might have come from – and potentially linked the event to evolutionary changes in viruses in a lake in Africa.
Earth must have experienced something exceptional 10 million years ago. A strange increase in the radioactive isotope beryllium-10 was found in rock samples from the floor of the Pacific Ocean.
The internal, infernal machinations of our planet may be way more complex than we suspected.
In the months following massive solar storm in May, 2024, Earth was girded by two new, temporary radiation belts of high-energy particles, trapped by the planet's magnetic field.
Bennu has a 1-in-2,700 chance of colliding with Earth in 2182, causing a global winter and drought.
Scientist have concluded water did not arrive as early during Earth's formation as previously thought.
The term "pyrocene" suggests a geologic epoch dominated by human-caused fires. Humanity and fire have been reforging the Earth since the end of the last glaciation, about 11,500 years ago.
