THE METEOR OF JULY 27, 1894, 7h 30m P. S. T. By Edward S. Holden A great number of observations of this splendid meteor were received at the Lick Observatory, either directly, or through the kind offices of Hon. A. S. Towne, Hon. C. F. Crocker, Hon. R. Thompson and others. Some of the best were not availab...
A pair of interacting galaxies might be experiencing the galactic equivalent of a mid-life crisis. For some reason, the pair, called Arp 82, didn't make their stars early on as is typical of most galaxies. Instead, they got a second wind later in life — about 2 billion years ago — and started pumpi...
NGC 2636 (also UGC 4583 and PGC 24747) is a magnitude +13.7 elliptical galaxy located 95 million light-years away in the constellation Camelopardalis. The galaxy was discovered by German astronomer Wilhelm Tempel using a 27.94 cm (11 inch) f/19 refracting telescope at the Arcetri Observatory on...
