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.
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.
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.
Deep under the frozen desert of western Antarctica, a hidden danger slumbers. Lurking beneath the massive, 1–2 kilometer-thick slab of frozen water lies an active volcanic rift, seething away in the deep, in the darkness.
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.
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.
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 rings of Saturn are some of the most famous and spectacular objects in the Solar System. Earth may once have had something similar.
During its flyby of Earth on 20 August, ESA's Jupiter Icy Moons Explorer (Juice) found ingredients for life in Earth's atmosphere - the so-called ‘CHNOPS’ elements (carbon, hydrogen, nitrogen, oxygen, phosphorous and sulphur).
An international team of scientists has successfully measured a planet-wide electric field thought to be as fundamental to Earth as its gravity and magnetic fields.
