Herschel links Jupiter’s water to comet impact 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)

NASA's PhoneSats set mark for first smartphone satellites

The Night Sky Monday, April 29 • It's almost May, yet the winter star Sirius still twinkles low above the west-southwest horizon in late twilight. How much later into the spring can you keep it in view? Tuesday, April 30 • The small but distinctive constellation Corvus, the Crow, is an icon of spring evenings (in the Northern Hemisphere). Look for its four-star quadrilateral in the south-southeast after dark, to the right of Saturn and Spica. Watch for Venus beginning to creep up into view shortly after sunset. Wednesday, May 1 • Have you ever really explored the richest 1° field of the Virgo Galaxy Cluster? How deeply into it can your scope go? Use the charts and guide in Alan Whitman's "Going Deep" column in the May Sky & Telescope, page 61. Thursday, May 2 • Last-quarter Moon. The Moon, between dim Capricornus and Aquarius, rises around the middle of the night (far below Altair). By daybreak Friday morning it's high in the south. Friday, May 3 • As soon as it's fully dark, look for the Big Dipper very high in the north-northeast. It's upside down, with its handle to the right and its bowl to the left. It's "dumping water" onto the much dimmer Little Dipper down below
