Editor’s note: A version of this story appeared in CNN’s Wonder Theory science newsletter. Analysis of ancient DNA recovered from human remains has illuminated the traits and ancestry of historic individuals — be it a mummified iceman, Chinese emperor or legendary composer. The origins of the empire and its people remained obscure until a landmark April 2022 study found they hailed from the Mongolian steppe. Carolyn Kaster/APNaturalists have spotted the first arrivals in this spring’s historic cicada dual emergence.

CNN —Close flybys of Io, one of Jupiter’s moons and the most volcanically active world in our solar system, have revealed a lava lake and a towering feature called “Steeple Mountain” on the moon’s alien surface. “We also got some great close-ups and other data on a 200-kilometer-long (127-mile-long) lava lake called Loki Patera. Juno detected the mountain with the help of the sun shining on Io’s surface, which created dramatic shadows that revealed a very sharp peak. NASA/JPL-Caltech/SwRI/MSSSAs an outdoors enthusiast, Bolton joked that Io’s Steeple Mountain should be one of the solar system’s skiing and snowboarding destinations. The mission team used Juno’s Microwave Radiometer instrument to create maps of Io’s surface, showing how incredibly smooth it is.

NASA's Juno spacecraft snapped detailed images of the most volcanically active world in our solar system on Saturday. During this close fly-by, the spacecraft spotted plumes of volcanic activity erupting from Io's surface in real-time. This encounter was the second in a set of two close fly-bys designed to provide new insight into the fiery phenomena that lurk beneath Io's surface. The twin flybys are designed to provide new insight into how Io’s volcanic engine works and whether a global magma ocean exists under Io’s rocky surface. NASA / JPL-Caltech / SwRI / ASI / INAF / JIRAMThe Juno spacecraft has orbited Jupiter every 38 days since 2016.
