Thirty years ago this month, humanity witnessed a rare sight: A comet measuring nearly 2 kilometres-wide slammed into the planet Jupiter, with a force that would have destroyed the Earth had we been ...

The Shoemaker’s and Levy co-discovered the comet. The emotional payoff of discovering a comet orbiting a planet was something Levy described as a “magic day,” which occurred on March 23, 1993.
