A time-lapse of Jupiter’s moons Europa and Io orbiting the gas giant has lately gone viral on the Internet due to its stunning beauty. Many users have argued that the time-lapse isn’t real because it’s so stunning.

While it is vital to be sceptical of photographs uploaded online, especially when phoney images are shared as real in exchange for clicks, we are pleased to announce that the lovely short film is 100% genuine. Snopes also conducted a fact check, which can be found here.

Kevin M.Gill created this fantastic video. M.Gill works as a NASA-JPL engineer specialising in planetary image processing. He made this animation by merging numerous photos taken by the Cassini space probe during its 2001 visit to Jupiter.(Yes, none of these photos or video segments were generated using a computer.)

Io and Europa can be seen circling Jupiter in the video. One of the video’s suspicions stems from the fact that Io, which is closer to Jupiter, appears to orbit at a slower rate than Europa, which is further away. There is, however, a straightforward explanation for this.
