Eugene Merle Shoemaker impact of a comet. Shoemaker–Levy 9 collided with Jupiter in July 1994. The resulting impact caused a massive "scar" on the face of Jupiter. Most scientists at the time were dubious of whether there would even be any evident markings on the planet. Shoemaker spent much of his later years searching for and finding several previously unnoticed or undiscovered impact craters around the world.

Seven of these asteroids were discovered together with his colleague Erwin Obermair and one together with Herbert Raab. Furthermore, he was involved in six other discoveries of asteroids between 1996 and 2005, which were assigned as site discoveries to the observatory Davidschlag by the International Astronomical Union.
