Meterorite

In 1807, a meteorite to be recorded in the U.S. fell at Weston (now called Easton), Conn., at 6:30 a.m., making a hole 5-ft long and 4.5-ft wide. This was the New World's first witnessed fall of a meteorite, with subsequent recovery of specimens, since the arrival of the European settlers. Yale Professor Benjamin Silliman's description of the fall and his chemical analysis of the stone meteorite, the first performed in the U.S., received much attention in the national and international press. A thirty-pound fragment of this Chondrite H4 became the nucleus of Yale University's Peabody Museum. This meteorite collection, the oldest in the country, was begun by Silliman.Image: The Fireball of 18 Aug 1873, near Newark-on-Trent, England. Etching by Henry Robinson.
