'Shot in the Dark' Star Explosion Stuns Astronomers
Last January, NASA's Swift satellite detected another gamma-ray
burst and quickly sent its alert to ground-based astronomers. Palomar
Observatory's 60-inch telescope was one of the first to respond,
using HPWREN for data transmissions.

HPWREN Aids Firefighters on Palomar Mountain
For the past four years, astronomers at the California Institute
of Technology's Palomar Observatory in Southern California have
been using the High Performance Wireless Research and Education
Network (HPWREN) as the data transfer cyberinfrastructure to further
our understanding of the universe. During the recent firestorms in
southern California HPWREN was used at the observatory for a much
more down-to-earth purpose -- providing vital emergency communications
when all other resources were cut off.

The HPWREN backbone now extends via an FCC-licensed path from the
ocean to the mountains
The radio and antenna replacement for a link in the southern loop
of the HPWREN backbone finally allows for an all FCC-licensed path
from coastal area to Mt. Laguna. This was an important step towards
stabilizing the performance of the network for many sensors and
other sites connected from the mountains and the desert.

HPWREN was Utilized for the Discovery of the Largest Exoplanet to Date
An international team of astronomers has discovered the largest-radius
and lowest-density exoplanet of all those whose mass and radius are
known, utilizing a global network of three small telescopes utilizing
mostly amateur-astronomy components and off-the-shelf four-inch
camera lenses: Sleuth telescope at Caltech's Palomar Observatory
in San Diego County; the Planet Search Survey Telescope (PSST) at
Lowell Observatory; and the STellar Astrophysics and Research on
Exoplanets (STARE) telescope in the Canary Islands.
