Reports Detail Mars Rover Clues to Atmosphere's Past

Super-Moon Monday: The 3rd (& Final?) Act

Earth's gold came from colliding dead stars

The Night Sky Monday, July 22 Twinkly Regulus is now 1¼° below Venus at dusk. Full Moon (exact at 2:16 p.m. EDT). The Moon travels across the sky tonight in western Capricornus. Tuesday, July 23 Look northwest after dark for the Big Dipper, hanging diagonally. Its handle is on the upper left. Follow the curve of the handle on around leftward, for a little more than a Dipper- length, to land on bright Arcturus in the west. Wednesday, July 24 The two brightest stars of summer evenings are Arcturus in the west now and Vega nearly overhead. They're 37 and 25 light-years away, respectively. Thursday, July 25 Jupiter is climbing higher and higher above faint Mars in the dawn. On what morning can you first pick up Mercury? The waning gibbous Moon rises due east late this evening. If you have a distant, flat eastern horizon, mark the spot. The Great Square of Pegasus stands on one corner well to the rising Moon's upper left. Friday, July 26 The Delta Aquariid meteor shower should be in its broad maximum all this coming week. This and other weak, long- lasting July showers with radiants in the southern sky increase the chance that any meteor you see these nights will be flying out of the south.
