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.
Data from NASA’s New Horizons spacecraft point to more prevalent water ice on Pluto’s surface than previously thought. Water ice is Pluto’s crustal “bedrock,” the canvas on which its more volatile ices paint their seasonally changing patterns. The new false-colour image is derived from observations in infrared light by the probe’s Ralph/Linear Etalon Imaging Spectral Array.
Emboldened by renewed contact with Europe’s comet lander, engineers are repositioning the mission’s Rosetta mothership this week to establish a reliable a communications link with the dishwasher-sized Philae landing craft, a prerequisite for resuming a science campaign abbreviated by a power shortfall last year.
