Johann Georg Palitzsch – 21 February 1788 in Prohlis) was a German astronomer who became famous for recovering Comet 1P/Halley on Christmas Day, 1758. The periodic nature of this comet had been deduced by its namesake Edmond Halley in 1705, but Halley had died before seeing if his prediction would come true.
The genus Paradisaea consists of six species of birds-of-paradise. The genus is found on the island of New Guinea as well as the nearby islands groups of the Aru Islands, D'Entrecasteaux Islands and Raja Ampat Islands. The species inhabit a range of forest types from sea level to mid-montane forests. Several species have highly restricted distributions, and all species have disjunct distributions. A 2009 study examining the mitochondrial DNA of the family found that the Paradisaea birds-of-paradise were in a clade with the genus Cicinnurus. It showed that the blue bird-of-paradise was a sister taxon to all the other species in this genus.
It was discovered, [...] at Aprohlis, near Dresden, by a farmer named Palitzsch, on the 25th of December 1758[...]
