It's Pluto, backlit by the Sun, imaged by NASA's New Horizons spacecraft in 2015.
Look carefully and you can see the planet's irregular topography and the layering in its atmosphere.

Under current global emissions trends, New Jersey is likely to experience 1.5-2.5 ft of sea-level rise between 2005 and 2070, 2.2-3.8 ft by 2100 (or 2.2-4.5 ft, considering potential ice-sheet collapse).
