2. Rock Spire in 'Spirit of St. Louis Crater' on Mars
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, May 5
Look low in the northeast in twilight for the rising of Vega, the "Summer Star." By nightfall Vega shines higher in better view. As it gains altitude it grows to be the equal of Arcturus, the "Spring Star" very high in the east (far to the upper right). They're both magnitude zero.
Wednesday, May 6
Summer is more than six weeks away, but the Summer Triangle is beginning to make its appearance in the east, one star after another. The first in view is Vega. It's already visible low in the northeast as twilight fades.
Next up is Deneb, lower left of Vega by two or three fists at arm's length. Deneb takes about an hour to appear after Vega does, depending on your latitude.
The third is Altair, which shows up far to their lower right around midnight.

Canes Venatici, the Hunting Dogs, floats near the zenith these evenings under the arch of the Big Dipper's handle.
Friday, May 8
The two brightest points in sky are Venus and Jupiter. At dusk they're in the west and high in the southwest, respectively. Find the halfway point between them. A little upper right of there is Pollux, with Castor to its right.
