light Pollution in Arizona Sparks Debate
Giant Radio telescope is Nearly Ready
Iridium Receives Another Offer
LIGHT POLLUTION IN ARIZONA SPARKS DEBATE
Astronomers and residents in Arizona are clashing over the United States' stiffest county ordinances designed to limit the amount of light pollution around two nearby observatories. Local businesses and residents feel that any outdoor light limits will put people at risk to increased crime, while Astronomers at Whipple Observatory on Mount Hopkins and the National Optical Astronomical Observatory on Kitt Peak want to keep the skies as dark as possible.
GIANT RADIO telescope IS NEARLY READY
The world's largest fully steerable radio telescope is nearly ready to make contributions to astronomy. Located in Green Bank, West Virginia, the $75 million telescope is 150 metres tall, extremely powerful, and capable of being pointed to an accuracy of one arc-second - the width of a human hair 2 metres away. Although it's a precise instrument, SETI researchers have no plans to use it to search for Extraterrestrial life - it's too specialized for scientific research.
IRIDIUM RECEIVES ANOTHER OFFER
Bankrupt Iridium, the doomed constellation of 88 satellites, has received a last minute bid to save the $5 billion satellite system from destruction. California-based CMC International has offered to pay $30 million to acquire the company's satellites and assets. It isn't clear whether Iridium is seriously considering the offer, since it's already been given court permission to destroy the constellation, by de-orbiting the satellites into the Earth's atmosphere.
