A solar eclipse can occur anywhere in the world, as science has long known
but it doesn't happen frequently here on Earth. This is where the most recent NASA photographs of the shadows
created by Mars' moons on the planet's surface come into play.
Since Martian moons never totally block out sunlight
these occurrences aren't exactly the same as the eclipses we observe here.
The two cast shadows on our neighbouring planet's surface as they move between the star and the watchers, in this case the rover.
Scientists have examined Phobos' peculiar behaviour on Mars in order to better understand.
