Smithsonian scientists have confirmed that chytridiomycosis, a rapidly spreading amphibian disease, has reached a site near Panama’s Darien region. This was the last area in the entire mountainous neotropics to be free of the disease. This is troubling news for the Panama Amphibian Rescue and Conservation Project, a consortium of nine U.S. and Panamanian institutions that aims to rescue 20 species of frogs in imminent danger of extinction.

Using the deepest X-ray image ever taken, astronomers found the first direct evidence that massive black holes were common in the early universe. This discovery from NASA's Chandra X-ray Observatory shows that very young black holes grew more aggressively than previously thought, in tandem with the growth of their host galaxies.

Astronomers have discovered a new comet that they expect will be visible to the naked eye in early 2013.A preliminary orbit computed by the Minor Planet Center at the Smithsonian Astrophysical Observatory in Cambridge, Mass., shows that the comet will come within about 30 million miles of the sun in early 2013, about the same distance as Mercury. The comet will pose no danger to Earth.
