Ice Cloud Heralds Fall at Titan's South Pole 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)

The Night Sky Sky & Telescope Friday, April 12 · As twilight fades in the west this evening, look far to the lower left of Jupiter for the crescent Moon. Less far above the Moon, you can see the Pleiades emerging into view — as shown at right. Saturday, April 13 · The thin crescent Moon floats between Aldebaran and the Pleiades in the west as twilight fades, with Jupiter above it, as shown at right. Sunday, April 14 · The Moon and Jupiter shine side by side high in the west after dusk, 3° or 4° apart, with Aldebaran below them. Although they look close together, the Moon is 1.3 light-seconds from Earth, Jupiter is currently 47 light-minutes distant, and Aldebaran is 65 light-years in the background. Monday, April 15 · The Moon right after dark is in the top of Orion's very dim Club. That's not far from the center of the huge Winter Hexagon: Sirius, Procyon, the Pollux-and-Castor pair, Capella, Aldebaran (under Jupiter), Rigel, and back to Sirius. Sky & Telescope
