This comet didn’t fall into the Sun, but rather whipped around it – or at least, it would have if it had survived its journey. Like most sungrazing comets, this comet was torn apart and vaporised by the intense forces near the Sun.
The disc of the Sun is represented by the white circle in this looping animation.
NASA’s New Horizons mission has found evidence of exotic ices flowing across Pluto’s surface, at the left edge of its bright heart-shaped area. New close-up images from the spacecraft’s Long-Range Reconnaissance Imager (LORRI) reveal signs of recent geologic activity, something scientists hoped to find but didn’t expect.
Pluto’s largest moon, Charon, is home to an unusual canyon system that’s far longer and deeper than Arizona’s Grand Canyon. As far as NASA’s New Horizons scientists can tell, the canyon informally named Argo Chasma has a total length of approximately 430 miles — one and a half times the length and five times the depth of the Grand Canyon on Earth.
