Neptune was supposedly discovered in 1846 by Johann Gottfried Galle using calculations by Urbain Le Verrier and John Couch Adams, making it a joint British-French-German discovery.

But these astronomers were not the first to observe Neptune. That honor goes to the famous Italian astronomer Galileo Galilei.

While sketching the moons of Jupiter with his newly discovered telescope, Galileo twice drew Neptune, which happened to be in conjunction with Jupiter in early 1613. It's usually said that Galileo mistook Neptune for a star because of its slow movement.

The Sailing Rocks of Death Valley

Via NPR:

A century ago, miners working in California's Death Valley reported seeing boulders on the desert floor with long trails behind them — as if the stones had been pushed across the sand. But despite 60 years of trying, no one ever saw what moved them.

Now scientists think they've solved the mystery of the "slithering rocks of Death Valley." Using GPS tags pasted to the boulders, and a video camera, a geologist from Scripps Institution of Oceanography and his engineer cousin have evidence that broad, jagged panes of melting ice push the stones across the desert, nudged in one direction or another by the breeze. The team details their results in the current issue of the journal Plos One.
