Скачать или смотреть NASA Found Dwarf planet Ceres is an ocean world with salty water under the surface

Ceres is a dwarf planet and the largest known object in the asteroid belt between Mars and Jupiter. And now we know it may be an ocean world with intriguing geologic activity taking place on and just below its surface, according to new research.While this global ocean beneath the planet's surface likely froze over time, remnants of it may still be present beneath a large impact crater on Ceres. The presence of salts may have preserved the liquid as a brine, despite cold temperatures.Between 2011 and 2018, NASA's Dawn mission embarked on a 4.3 billion-mile journey to two of the largest objects in our solar system's main asteroid belt. Ceres is about 592 miles across, 14 times smaller than Pluto. Dawn visited Vesta and Ceres, becoming the first spacecraft to orbit two deep-space destinations.False color was used to highlight the recently exposed brine, or salty liquids, that were pushed up from a deep reservoir under Ceres' crust in the Occator Crater.This new research is based on observations made during Dawn's orbit of Ceres between 2015 and 2018, including close passes it made of the dwarf planet just 22 miles above the surface toward the end of the mission.During that time, Dawn was focused on the 57-mile-wide Occator Crater, a 22-million-year-old feature that appeared to showcase bright spots. These eye-catching characteristics were discovered to be sodium carbonate, or a compound including oxygen, carbon and sodium.Data from the end of Dawn's mission revealed an extensive and slushy reservoir of brine, or salty liquid, beneath the crater. It's 25 miles deep and extends out for hundreds of miles. #Ceres #Nasa
