2. NASA’s OSIRIS-REx Spots Target and Begins Asteroid Operations Campaign
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, August 28
• After nightfall this week, Arcturus and the Big Dipper shine equally high in the west and northwest, respectively.
Wednesday, August 29
• Summer's end approaches. Soon after dark now, Cassiopeia has risen as high in the northeast as the Big Dipper has sunk down to in the northwest. Find Polaris a little above the midpoint between them.
Thursday, August 30
• Now that the waning Moon doesn't rise until nearly an hour after dark, you have a window of darkness to explore the telescopic double stars and open clusters in high Lacerta, the Lizard Do you know why the 17th-century creator of Lacerta also named it Stellio? Hint: not real stars.*
Friday, August 31
• Look for bright Vega passing the zenith as twilight fades out, if you live in the world's mid-northern latitudes. Vega goes right through your zenith if you're at latitude 39° north (near Baltimore, Kansas City, Lake Tahoe, Sendai, Beijing, Athens, Lisbon).
Then Deneb follows two hours behind. For Deneb to pass exactly through your zenith you need to be a little farther north, at latitude 45°: near Bangor, Montreal, Minneapolis, mid-Oregon, northernmost Japan, Bucharest, Milan.
Saturday, September 1
• As twilight fades this evening, spot Venus very low in the west-southwest as shown here. Upper right of it by just 1.3° is Spica, a 1st-magnitude star but less than 1% as bright as Venus. Can you see Spica naked-eye through the twilight? They're about a finger-width at arm's length apart. Or, try binoculars.
