Sun rises on the Moon.
Dec 8, 2005 Press the correct buttons and the ATM spits out the cash you need for the weekend's jaunt. Lying behind the machine's panel, cables connect the ATM to computers that process millions of such transactions every second. Before this nano-age, people kept track of numbers using paper, pencil and an unfailing eye that looked at one item then the next. These human computers supported financiers and as George Johnson tells in his book, Miss Leavitt's Stars, they were also the backbone of early 20th century astronomy.
Dec 8, 2005 This beautiful photograph of Saturn was taken when Cassini was lined up directly with the planet's rings. The black line near the top of the photograph are the rings. It's possible to see the intricate cloud patterns across the planet's surface, especially right at the terminator, which separates day from night. Cassini took this image on October 31, 2005 when it was 1.2 million kilometers (800,000 miles) from Saturn.
Dec 8, 2005 When the Sun rises on the Moon after two weeks of lunar night, the dust begins to stir. This dust storm stretches right across the Moon at the terminator (the line between day and night), from pole to pole. An instrument left by the Apollo astronauts to detect micrometeorite impacts first spotted this strange phenomenon. It could be that the night side of the Moon is negatively charged, and the day side is positively charged. As the terminator shifts across the Moon, it picks up the dust and shifts it sideways.
