Scientists have found a massive area the size of 1.5 football fields, now dubbed "The Coliseum," which was once a popular thoroughfare to water for multiple species of prehistoric beasts over many generations some 70 million years ago.

A new genus and species of ancient sea worm with an impressive set of star-shaped chaetae has been identified, after its fossil first puzzled paleontologists. Thanks to its alien-worm-like appearance, scientists found a fittingly sci-fi name for it.

If you’ve ever felt like you need more hours in the day, well how does 60 sound? A new study suggests we’d have 60-hour days by now if a stalemate between the Sun and Moon hadn’t interfered with Earth’s rotation for over a billion years.

The Earth’s inner core is incredibly tricky to study, since it’s buried beneath thousands of miles of rock. New seismic studies suggest that it’s not just a solid ball of iron, as has been assumed, but might have pockets of liquid iron throughout.

Using microwave instruments to peer deep beneath the surface of the far side of the Moon, researchers have detected a ‘hotspot’ they say is a large subsurface granite mass, suggesting the Moon is more "Earth-like" than we thought.

As far as landscapes go, Mars is pretty dull – it’s mostly just rocks and craters. But now the Perseverance rover has spotted a couple of particularly weird rocks that have been hollowed out in eerie shapes.

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.
