"The largest digital camera ever built," the Pan-STARRS gigapixel camera focal plane is seen at right, nearly complete in June. There are 60 Orthogonal Transfer CCDs, each of which (left) is comprised of an 8x8 array of 600x600-pixel CCDs. A 56-cm. window with a corrector lens will be assembled over the focal plane. See news below. Images courtesy of Pan-STARRS.

Minor-Object News on 21 July '07
- "CBC site for gathering of celestial observers," Tri-City Herald 21 July - Quote: "Columbia Basin College in Pasco ... is the setting for the annual meeting of the International Occultation Timing Association, or IOTA, a group that observes events similar to an eclipse to gather information about the size and shape of celestial objects... [They also] came to observe asteroid 153 Hilda [which they] learned early Friday morning ... is about 176 kilometers across horizontally and measures about 149 kilometers vertically." - Note: See David Dunham's page about the 20-21 July meeting.
- "Gigapixel camera nearly complete," Pan-STARRS 21 July - Quote: "The overall length of the camera is about 1.5 meters." - Note: See pictures above and read and see more on the Pan-STARRS Camera Design page. The standalone PS-1 prototype telescope is preparing to receive this camera next month, and three more are to be built for the full Pan-STARRS project, which will have four telescopes.
- "Dawn ELV status report," NASA KSC 20 July - Quote: "Dawn remains atop the Delta II launch vehicle at Pad 17-B. The spacecraft will be removed from the launch vehicle on Saturday, July 21, and returned to the Astrotech payload processing facility near NASA's Kennedy Space Center."
- "Spitzer Searches for the Origins of Life," NASA JPL 13 June - Quote: "Achim Tappe ... used Spitzer's infrared spectrograph instrument to detect abundant amounts of polycyclic aromatic hydrocarbons along the ridge of supernova remnant N132D [in] the Large Magellanic Cloud... These intriguing molecules are comprised of carbon and hydrogen atoms, and have been spotted inside comets, around star-forming regions and planet-forming disks... [Astronomers] suspect that some of Earth's original carbon might have come from these molecules -- possibly from comets that smacked into the young planet. Astronomers say there is some evidence that a massive star exploded near our solar system as it was just beginning to form almost 5 billion years ago. If so, the polycyclic aromatic hydrocarbons that survived that blast might have helped seed life on our planet."
NEOCP Activity on 21 July '07
The MPC's NEO Confirmation Page has 7 listings: 1 new, 6 updated
When last checked at 2357 UTC today, the Minor Planet Center's NEO discovery Confirmation Page (NEOCP) had one new and six updated listings. Of these, two were "one nighters." So far Major News has counted a total of eight objects listed on the NEOCP at some point today.
To learn how observers use the NEOCP, see Suno Observatory's Practical guide on how to observe NEOCP object.
