Published in the journal
AGU Advances, it suggested that back when the planet was a molten ball of magma, its mantle held far less water than it does today. The mantle is the thick, semi-solid layer that sits between the planet’s dense, super-heated inner layer called the core and its thin outer one called the crust.

In March 2020, the Vera C. Rubin Observatory sat partially erected, perched on Chile’s Cerro Pachón in the foothills of the Andes Mountains. The Observatory had halted construction of the 8.4-meter telescope and its associated buildings due to the coronavirus pandemic. By October 2020, with safety precautions in place, construction teams began to slowly return to the mountain. Earlier this month, just one year after its unexpected closure, the Rubin Observatory reached a major milestone when crew used a crane to lower the top end of the telescope, weighing approximately 28 tons and measuring 10 meters in diameter, through the observatory’s open dome and into its place on the telescope. This was one of the last remaining heavy pieces to be
