> 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....

> 2005 Astronomy Day Award Winners
>
> 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
> program....

> 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....
