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.

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.

Vezi curiozități despre aceștia, dar și cine este moldoveanul care a descoperit 10 asteroiziOrganizația Națiunilor Unite (ONU), în 2016, a stabilit oficial că Ziua Internațională a Asteroizilor, propusă de Brian May, chitaristul trupei Queen, să fie sărbătorită în fiecare an pe 30 iunie. Asteroid Day este o inițiativă internațională care își propune să informeze și să educe publicul despre riscurile generate de asteroizi și modalitățile de protejare. Astronomul originar din Chișinău care a descoperit 10 asteroizi. Mai mulți ani, a fost cercetătorul științific principal al acestui observator, iar la sfârșitul vieții a îndeplinit și funcții de conducere. Pe lângă faptul ca este primul asteroid descoperit, Ceres este si cel mai mare asteroid cunoscut , de cca.
