Sicily's Mount Etna unleashed the latest in a year-long series of fiery shows this last weekend. It was the Italian peak's 23rd such display since January 2011, according to a scientist who faithfully documents the peak's regular paroxysms.

The volcano's latest episode, which reached its peak in the wee hours Sunday (April 1), lit up the night, spouting molten rock many hundreds of feet into the air for about an hour and a half.

The rugged mountains of northeastern Oman, on the eastern coast of the Arabian Peninsula, are bone dry, yet these peaks once lay beneath the bottom of the sea.

The rocks exposed in the Oman Mountains used to lie in Earth's interior, at the boundary between crust and the mantle, but when an ancient ocean narrowed and closed, the colossal geological forces at work also thrust the ancient seafloor skyward, according to a NASA statement.

James Cameron's deep-diving team has been keeping busy.

Just days after the filmmaker plunged more than 35,756 feet (10,890 meters) into the Pacific Ocean to the Mariana Trench, the deepest place on Earth, his team piloted Cameron's innovative submersible to yet another deep-sea spot.

This time, members of the expedition took Cameron's lime-green Deepsea Challenger to a depth of 3,600 feet (1,100 meters) off the coast of the tiny island of Ulithi, part of Micronesia.
