Last week, NASA released images of Io, one of Jupiter's moons, casting a big, dreadful shadow on the planet. And earlier today, Kevin M. Gill, a software engineer at NASA, posted his image processed from the shadows, giving us a clear picture of what a solar eclipse on Jupiter would look like.
And here is a slightly larger image of Gill's picture:
And for those who are curious to know why the shadow of Io is so clearly defined in relation to a solar eclipse on Earth, distance plays a big role in disparity. Mars photographer Doug Ellison pointed out that the sun appears much smaller on Jupiter than on Earth:
And the astrophysicist Katie Mack explained that the distance separating Io from Jupiter, which makes it look four times larger than the Sun, is the reason why its shadow is so clear and its penumbra weaker.
