2. Mystery Solved: Martian Moons Formed By A Giant 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)

5. The Night Sky Tuesday, July 12
As soon as it's dark, look just ½° north (upper right) of Jupiter for 4th-magnitude Sigma Leonis, Leo's hind foot. Tonight they're the closest they will appear.
Wednesday, July 13
The Big Dipper, high in the northwest after dark, is now turning around to "scoop up water" through the evenings of summer and early fall.
Thursday, July 14
The Moon, in its monthly cycle around the sky, once again forms a long, squashed rectangle with Mars, Saturn and Antares. Mars shines below the Moon after dusk, Saturn glows farther to the Moon's left, and under Saturn is Antares — as shown in the slightly earlier twilight scene at right.
Friday, July 15
Tonight the Moon, Saturn, and Antares form a roughly vertical stack in the south at dusk, as shown above, with Mars off to their right. Watch them all tilt westward until they set around 2 to 3 a.m.
