July Sees Gathering of Five Bright Celestial Lights
An array of five of the sky’s leading lights gather together over the western horizon on mid-July nights. Venus, the dazzling “evening star,” is sneaking past Regulus, the brightest star in the constellation of of Leo, the lion. Venus was well to the lower right of Regulus as July opened, but the planet is moving to the upper left of the bright star.
The crescent Moon joined this bright pair on July 14, forming a triangle with Venus and Regulus. The orange planet Mars and golden Saturn hang a little higher, to the group’s upper left.

NASA and Microsoft Provide Mars 3-D Close Encounter
NASA and Microsoft Research are bringing Mars to life with new features in the “WorldWide Telescope” software that provide viewers with a high-resolution, 3-D map of the Red Planet.
Microsoft’s online virtual telescope explores the universe using the images that NASA’s spacecraft return from other worlds. Teams at NASA’s Ames Research Center in Moffett Field, Calif., and Microsoft in Redmond, Wash., jointly developed the software necessary to make NASA’s planetary data available in WorldWide Telescope.
The fully interactive images and new NASA data will allow viewers to virtually explore Mars and make their own scientific discoveries. New features include the highest resolution fully interactive map of Mars ever created, realistic 3-D renderings of the surface of the planet, and video tours with two NASA scientists, James Garvin of Goddard Space Flight Center in Greenbelt, Md., and Carol Stoker of Ames.
Garvin’s tour walks viewers through the geological history of Mars and discusses three possible landing sites for human missions there. Each landing site highlights a different geological era of the planet. Stoker’s tour addresses the question “Is there life on Mars?” and describes the findings of NASA’s Mars Phoenix Lander.
“Our hope is that this inspires the next generation of explorers to continue the scientific discovery process,” said Ames Center Director S. Pete Worden.

July 24 Lecture in Altadena Explores the Infrared Universe
At 2:30 p.m. on Saturday, July 24, you can explore a new Universe as surveyed by an infrared telescope in space. Dr. Edward L. (Ned) Wright, Professor of Physics and Astronomy at UCLA, will speak on “Exploring the Universe with WISE” in a lecture at the Altadena Public Library.
The Wide-field Infrared Survey Explorer (WISE) was launched in December 2009, and its all-sky survey began in mid-January 2010. WISE is expected to detect hundreds of millions of stars and galaxies, including millions of ultra-luminous infrared galaxies and quasars; hundreds of thousands of asteroids; and hundreds old cold brown dwarf stars. This orbiting telescope takes more than 7,000 framesets per day, with each frameset covering 0.6 square degrees of sky.
The lecture begins at 2:30 p.m. It is free of charge, and all are welcome. Refreshments will be served before the talk, beginning at 2:00 p.m. The Altadena Public Library is located at 600 E. Mariposa Street in Altadena, two stop signs west of Lake Avenue at the corner of Mariposa and Santa Rosa Avenue (“Christmas Tree Lane”).
