The inner Earth is a mysterious place, and now scientists may have uncovered a strange new secret. According to a new study, the Earth’s inner core may have recently stopped rotating, relative to the surface, as part of a decades-long cycle.

Life on Earth has persisted for billions of years through many extreme climate events. MIT scientists have analyzed 66 million years of climate data and found a stabilizing mechanism for global temperatures that plays out on large timescales.

Astronomers have discovered three new near-Earth asteroids, including the closest known to the Sun. Another is one of the largest known asteroids considered potentially hazardous to Earth, measuring almost a mile wide with an orbit close to our own.

The Earth’s magnetic field isn't something we can usually see, feel or hear. That last point has now changed though, as scientists and musicians have worked together to convert magnetic field data into sound – with spooky results.

As the dinosaurs could attest, it’s worth keeping an eye on space rocks buzzing around Earth. Many observatories are doing just that, and astronomers have announced that we’ve just ticked over the milestone of 30,000 near-Earth asteroids discovered.

Predicting the likelihood and severity of earthquakes is important, but it’s hard to account for all factors. Researchers in New Zealand have now uncovered an overlooked factor that could affect the impact of the next big quake – tiny marine fossils.

It’s believed that the Moon formed billions of years ago, from debris from a cosmic collision with Earth. New high-resolution simulations not only illustrate the idea in stunning detail, but reveal that the Moon’s birth might have taken mere hours.
-
Around 66 million years ago a huge asteroid slammed into Earth and wiped out most life. Two new studies have identified evidence that the impact triggered global tsunamis almost a mile high and mega-earthquakes that rumbled for months afterwards.
-
New modeling from researchers at Curtin University has simulated 300 million years of tectonic plate movement to predict the formation of a supercontinent called Amasia. The modeling estimates the Pacific Ocean closing and America colliding with Asia.
-
Geologists claim to have discovered a long-term cycle that may link the formation of Earth’s continents to our travels through the galaxy. The team claims a correlation between increased comet impacts and Earth crossing the galactic spiral arms.
-
The best bits of thunderstorms often happen above the clouds. Scientists have now described in detail the most powerful “gigantic jet” of lightning ever observed, which blasted energy equivalent to 60 regular lightning bolts upwards into space.

The Moon may look like a big dry ball, but there’s more water up there than you might expect. In a new study, scientists have shown that at least some of it could have been showered onto the lunar surface from the Earth’s atmosphere.
