Looking back at data from the geology experiments left on the lunar surface by the Apollo missions half a century ago, scientists have finally determined that the Moon has a solid core surrounded by a fluid outer core similar to the Earth's.

Everyone is familiar with sunken treasure on the ocean floor. Now, researchers may have found an ancient ocean floor that is itself a type of geological buried treasure. What's more, it has mountains that are five times taller than Everest.
-
After decades of speculation, astronomers have discovered the first direct evidence of volcanic activity on Venus. Radar images of Earth’s “twin” taken just a few months apart reveal a recent eruption.
-
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.

NASA’s Curiosity rover has discovered opal on Mars. The deposits may prove to be valuable to future Martian explorers not as jewelry but as a potential source of water.
-
Mars is usually considered a geologically dead planet, but a new study challenges that idea. Multiple lines of evidence reveals a giant plume of magma is forcing its way up through the mantle and producing seismic activity in one region of the surface.
-
Scientists have discovered at least two new minerals inside one of the largest meteorites ever found. The iron-based minerals have never been spotted in nature, and could hint at unknown geological processes and new material uses.
-
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.

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.
-
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.
-
NASA’s Perseverance rover has captured some incredible imagery since landing on the Red Planet early last year, but none as detailed as its latest effort, a stunning mosaic made up of more than 1,000 separate images.
