David H. Levy special edition telescope, "The Comet Hunter" was co-designed by Levy. Together with Martyn Ives, David Taylor, and Benjamin Woolley, Levy won a 1998 News & Documentary Emmy Award in the "Individual Achievement in a Craft, Writer" category for the script of the documentary "3 Minutes to Impact" produced by York Films for the Discovery Channel. David H. Levy David H. Levy (born May 22, 1948) is a Canadian astronomer, science writer and discoverer of comets and minor planets, who co-discovered Comet Shoemaker–Levy 9 in 1993, which collided with the planet Jupiter in 1994. Levy was born in Montreal, Quebec, Canada,
Comet Shoemaker–Levy 9 largest impacts. The waves were thought to be travelling within a stable layer acting as a waveguide, and some scientists thought the stable layer must lie within the hypothesised tropospheric water cloud. However, other evidence seemed to indicate that the cometary fragments had not reached the water layer, and the waves were instead propagating within the stratosphere. Radio observations revealed a sharp increase in continuum emission at a wavelength of after the largest impacts, which peaked at 120% of the normal emission from the planet. This was thought to be due to synchrotron radiation, caused by the injection of relativistic
