And now, researchers investigating artifacts from the neighboring city of Herculaneum are using new technology to peek beneath Vesuvius’ blanket of ash and mud to uncover more of history’s best kept secrets. The wonderOne of the Herculaneum scrolls undergoes analysis using lasers. EduceLab/University of KentuckyArtificial intelligence has revealed the first nearly complete passages to be decoded from the charred, brittle Herculaneum scrolls. Mimas could change the way scientists understand ocean worlds across our solar system, which may harbor life beyond Earth. They find wonder in planets beyond our solar system and discoveries from the ancient world.

☆ Saturn’s ‘Death Star’ moon is hiding an internal ocean, scientists say

CNN —Astronomers have uncovered additional evidence that one of Saturn’s smallest moons, Mimas, is hiding a global ocean beneath its icy surface. Discovered in 1789 by English astronomer William Herschel as a tiny dot near Saturn, Mimas was first imaged from space by the Voyager probes in 1980. Craters cover the surface of Mimas, but the largest one is 80 miles (about 130 kilometers) across and causes the moon to resemble the Death Star from the “Star Wars” films. But Saturn’s Enceladus appears younger because active geysers have contributed to resurfacing, or depositing of new, fresh material on that moon’s surface. “Mimas certainly demonstrates that moons with old surfaces can be hiding young oceans, which is pretty exciting,” Rhoden said.

CAPE CANAVERAL, Fla. (AP) — Astronomers have found the best evidence yet of a vast, young ocean beneath the icy exterior of Saturn’s Death Star lookalike mini moon. Barely 250 miles (400 kilometers) in diameter, the heavily cratered moon lacks the fractures and geysers — typical signs of subsurface activity — of Saturn’s Enceladus and Jupiter’s Europa.

Co-author Nick Cooper of Queen Mary University of London said the existence of a “remarkably young” ocean of liquid water makes Mimas a prime candidate for studying the origin of life.

☆ On Pluto you could throw a baseball over the Great Pyramid of Giza, a scientist's animation reveals

An astronomer's animation reveals how far the average person could throw a ball on different worlds. On Pluto, your baseball could clear the Great Pyramid of Giza. Watch a ball throw on each planet in our solar system, plus Pluto and the moon, below. At just two-thirds the diameter of our moon, Pluto has such weak gravity that your baseball could clear the 455-foot-tall Great Pyramid of Giza — with room to spare. The video plays out in "real time," showing how long each ball throw would take, O'Donoghue said.
