Watch a solar eclipse from the surface of another planet

NASA's Curiosity rover recently turned its camera skywards to catch a glimpse of Phobos as it passed directly in front of the Sun.


Last month we showed you the first video ever taken from Mars of one moon eclipsing the other. Now, NASA has stitched together 89 images to produce a sequence showing an annular (or ring) eclipse of the sun by Phobos, the larger of Mars' two moons. The video shows the eclipse in real time, which took a mere 32 seconds to unfold.


"This one is by far the most detailed image of any Martian lunar transit ever taken," Curiosity scientist Mark Lemmon of Texas A&M University said in a statement.

The images were taken by Curiosity's MAST camera on August 20th.

Until we started seeing these eclipse videos from Curiosity, I always assumed that moons tended to be about the same size (maybe even relative in size to the planet) in the sky as our moon.
