20D/Westphal was a periodic comet with an orbital period of 61 years. It fits the classical definition of a Halley-type comet with (20 years < period < 200 years). It was originally discovered by the German astronomer J. G. Westphal (Göttingen, Germany) on July 24, 1852. Read more

In Socorro, the New Mexico School of Mines (now New Mexico Tech) tested a sample from the purported impact site of a green fireball that had fallen on July 24, 1949 and found that it was rich in copper, an element that when burned, turns bright green. Source Dr. Lincolm LaPaz found this highly signific...

Lives and Deaths of Sibling Stars In this striking new image from ESO's La Silla Observatory in Chile young stars huddle together against a backdrop of clouds of glowing gas and lanes of dust. The star cluster, known as NGC 3293, would have been just a cloud of gas and dust itself about ten million year...

V854 Cen has the rather dubious distinction of having been discovered on 3 separate occasions while its true character remained unrecognised for almost 2 decades. This is despite it being third brightest of the RCB stars with a maximum visual brightness near magnitude 7.5. The initial discovery w...
