Amateur astronomer John McKeon was observing the king of planets by telescope from Swords, Ireland, on March 17 when he captured this stunning time-lapse video of something hitting Jupiter. McKeon was recording the transit of Jupiter’s moons Io and Ganymede with an 11-inch Schmidt-Cassegrain telescope and his ASI120mm camera when something struck Jupiter, and he struck cosmic pay dirt.
“The original purpose of the imaging session was to get this time-lapse, with a happy coincidence of the impact in the second, last capture of the night,” McKeon wrote in a YouTube video description.
