Special Replay - The Moon Photobombing Saturn from Australia
The next celestial event begins in:
The Perseid Meteor Shower 2015
The Perseid meteor shower, the most prolific meteor shower of the year, peaks on the night of August 11-12, 2015. The Perseids is a favorite of many stargazers because it shows more bright meteors than most showers, usually about 50-60 per hour. Join Slooh astronomers for a live dark-sky broadcast of the Perseid meteor shower on August 12, 2015. Like most meteor showers, the Perseids are simply dust-sized pieces of icy debris expelled from a comet, in this case, Comet Swift-Tuttle. As the Earth passes through the comet's debris trail once each year, some particles streak through our atmosphere and heat up, leaving a transient bright glow we call a meteor. The tiny particles burn up in the atmosphere. Very few, if any, make it to the Earth's surface. Some hit the moon, too, though they're too faint to see, even with a telescope.

Neptune at Opposition
Neptune, the most distant of the major planets in our solar system, makes its closest approach to Earth on September 1. Join Slooh for a show with live telescope feeds and informative discussion about Neptune as it reaches opposition in 2015. Records show the first human to see Neptune was Galileo in 1612. He happened upon the planet by chance, but he did not notice its motion and recorded it as a star. The planet was discovered more than 200 years later in 1846 by the astronomers Adams and Leverrier who independently calculated the expected position of the planet by its effect on the orbit of Uranus. The planet was first observed using these calculations by German astronomer Johann Galle at the Berlin Observatory.
