2. Ice Confirmed at the Moon’s Poles
In this computer graphic, NASA's Voyager 1 probe, moving toward upper left, nears the edge of the sun's influence, flying through a region of space dominated by a "magnetic highway" that helps mediate the flow of particles into and out of the solar system. The region includes particles from the sun's southern hemisphere that have been forced northward by the pressure of the interstellar wind. Voyager 1 is expected to cross the boundary into interstellar space sometime within the next few years if not sooner. (Credit: NASA)

5. The Night Sky Sky & Telescope Tuesday, August 21
• Now Saturn glows to the Moon's right at dusk. And Mars shines farther to the Moon's lower left.
Wednesday, August 22
• The waxing gibbous Moon shines upper right of Mars this evening. Unlike Mars, the Moon lies in a nearly straight line with Saturn, Jupiter, and Venus (running from the right of the Moon very far to the west). To see how straight this line really is, hold a yardstick or a tightly stretched string along it. Why is this so? The Moon is nearly on the ecliptic tonight, but Mars is a good 6.1° south of the ecliptic.
Thursday, August 23
• Now Mars is lower right of the Moon, as shown at right.
Friday, August 24
• After dark as August nears its end, the Great Square of Pegasus looms up in the east, balancing on one corner. Its stars are only 2nd and 3rd magnitude. Extending leftward from the Square's left corner is the main line of the constellation Andromeda, made of three stars (including the corner) about as bright as those forming the Square.
This whole giant pattern was named "the Andromegasus Dipper" by the late Sky & Telescope columnist George Lovi. Shaped sort of like a giant Little Dipper with an extra-big bowl, it currently lifts its contents upward.
