2. Cassini Spies Titan's Tallest Peaks
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)

By 11 p.m. the bowl of the Big Dipper stands upside down high in the north-northeast, straight over the bowl of the dim Little Dipper as if dumping water into it. In the fall, they do the reverse.

• The huge, bright Winter Hexagon is still in view after dark, filling the sky to the southwest and west. It's the biggest well-known asterism in the sky. Start with brilliant Sirius in the southwest, the Hexagon's lower left corner. High above Sirius is Procyon. From there look even higher for Pollux and Castor, rightward from Castor to Menkalinan and bright Capella, lower left from there to Aldebaran, lower left to Rigel at the bottom of Orion, and back to Sirius.

• Draw a line from Castor through Pollux, and follow it farther out by a big 26° (about 2½ fist-widths at arm's length). You're at the dim head of Hydra, the Sea Serpent. In a dark sky it's a subtle but distinctive asterism about the size of your thumb at arm's length. Binoculars show it easily through light pollution.

• Look south before dawn tomorrow morning the 29th for the waning Moon, Saturn, Mars, and Antares forming an uneven quadrangle, as shown at right.
Tuesday, March 29
• Jupiter's Great Red Spot should cross Jupiter's central meridian around 10:11 p.m. Eastern Daylight Time. At 10:54 p.m. EDT, Io disappears behind Jupiter's celestial-western limb. Io reappears from eclipse out of Jupiter's shadow at 1:41 a.m. EDT, just off Jupiter's opposite limb. Subtract three hours from these times to get PDT.
