science πͺ Liquid nitrogen flows under Pluto's heart glacier
Scientists discovered evidence that liquid nitrogen is rising to the surface of Plutoβs Sputnik Planitia. This discovery was made through a new analysis of images captured during NASA's New Horizons flyby in 2015. The ice sheet covers over a million square kilometers and forms the planet's heart-shaped feature. This suggests Pluto is geologically active, which is surprising for a distant world. Further study could help understand other icy moons like Europa. πͺ
