    > TRIPLE-STAR PLANET
    >
    > Can multiple-star systems support life-bearing planets? This is an
    > important question for astrobiologists because more than half of all stars
    > in our galaxy belong to binary, triple, or higher-order systems.
    > Astronomers have found several giant planets orbiting one member of widely
    > separated binary systems. But a recent discovery, if confirmed, shows that
    > tighter multiple-star systems can also have planets.
    >
    > In the July 14th NATURE, Maciej Konacki (Caltech) reports a planet
    > orbiting the triple-star system HD 188753 in Cygnus. Konacki employed a
    > novel technique that he developed to find planets around binary stars. He
    > used the 10-meter Keck I Telescope to tease out the gravitational wobble
    > caused by a planet with at least 1.14 Jupiter masses in a tight, 3.35-day
    > orbit around the primary star, a G dwarf nearly identical to the Sun. The
    > primary, in turn, has two stellar companions (a G-dwarf and a K-dwarf) a
    > little less massive than the Sun that orbit each other as a binary pair.
    > The primary star and the two secondary stars, in turn, go around each
    > other in an elongated orbit that ranges from about 6 to 18 times the
    > average Earth-Sun distance, or about from Jupiter's to Uranus's distance
    > from the Sun....

    > SUPERNOVA IN M51
    >
    > A 14th-magnitude supernova has appeared in a spiral arm of the Whirlpool
    > Galaxy, M51 in Canes Venatici, high overhead these evenings. Although the
    > supernova is probably too faint for most visual observers, it's well
    > within reach of astro-imagers....

    > The Cradle of Aviation Museum was chosen by the Astronomical League as the
    > top winner for this year's SKY & TELESCOPE Astronomy Day Award. The annual
    > prize consists of a commemorative plaque and a $250 gift certificate from
    > Sky Publishing.
    >
    > Based in Garden City, New York, the Cradle of Aviation Museum involved
    > many other organizations and hosted special activities on Astronomy Day
    > last April, attracting 2,412 attendees plus an additional 3,272 during
    > Astronomy/Space Week. In addition to the top prize, the museum also won
    > the award for "Best New Idea" by inviting firefighters from Nassau County
    > to demonstrate spinoff technologies that were derived from the US space

    > James G. Baker (1914-2005)
    >
    > Harvard-educated astronomer James G. Baker, one of the true giants among
    > 20th-century optical designers, died suddenly on June 30th at his home in
    > Bedford, New Hampshire. He was 91.
    >
    > Although his foremost interest was astronomy, his genius for optical
    > innovation emerged while he was a graduate student in the early 1940s, and
    > it dominated his professional career. His contributions to the field of
    > photographic reconnaissance are legendary. They began with lens designs
    > used during World War II and extended through the Cold War years with the
    > U-2 and SR-71 Blackbird spy planes and eventually satellite reconnaissance
    > programs. He also contributed to many civilian projects, including the
    > exotic mirror system of Polaroid's revolutionary SX-70 consumer camera in
    > the early 1970s....
