2. Curiosity rover Celebrates 1 Year on Mars with Dramatic Discoveries
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 Monday, August 5
· The little constellation Scutum, off the tail of Aquila, is faint to the naked eye but important for its super-rich Milky Way field and its deep-sky objects. See Fred Schaaf's "The Shield of King Sobieski" in the August Sky & Telescope, page 47.
Tuesday, August 6
· A binocular challenge: Spot Venus in twilight low in the west and then, using binoculars, see if you can detect the 4.0-magnitude star that it's closely passing. The star is Sigma Leonis, Leo's hind foot, just 0.6° above Venus depending on your time and location.
· New Moon (exact at 5:51 p.m. Eastern Daylight Time).
Wednesday, August 7
· Bright Vega passes closest to overhead around 10 or 11 p.m., depending on how far east or west you are in your time zone. How closely it misses your zenith depends on how far north or south you live. It passes right through the zenith if you're at latitude 39° north (Washington DC, Cincinnati, Kansas City, Lake Tahoe). How closely can you judge this by looking?
Thursday, August 8
· The Perseid meteor shower is ramping up! It should peak late this Sunday and Monday nights. See our article Get Ready for the 2013 Perseids and make your plans.

Friday, Aug. 9
· Early in twilight, about a half hour after sunset, look very low in the west below Venus for the thin crescent Moon, as shown at right. Binoculars will help.
