A new NASA Earth study found Greenland’s ice sheets are changing, causing freshwater rivers below the surface to be rerouted. Those rivers, which carry important nutrients to the ocean, can impact local ecology and surrounding communities. go.nasa.gov/37PMRnI

NASA's Perseverance Mars Rover rover is midway to Mars! The spacecraft has traveled 146.3 million miles (235.4 million kilometers) and has the same distance to go before its rendezvous with the Red Planet on Feb. 18, 2021. The journey continues. #CountdownToMars go.nasa.gov/2HEte74

Elves and sprites on Jupiter? It’s not those mythical creatures, but rather brief flashes of light dancing in the gas giant’s upper atmosphere. Data from our #JunoMission indicate these transient luminous events could happen high above Jupiter’s water cloud layer. go.nasa.gov/3ox372T
