Heads up, west coast types with telescopes! Early tomorrow morning, you have the chance to see a rare event. Four of Saturn's moons are going to pass in front of the planet. That's Titan, Mimas, Dione and Enceladus. Both of the lovely potentially life-supporting moons will be visible to people on Earth on the same day. This sort of thing happens only once every 14 or 15 years, so if the sky's clear, get yourself outside and peer upwards.
The Hubble telescope will also be watching, so expect spectacular images in the next day or so.
