You can now buy the recently released book, Fall of a Thousand Suns: How Near Misses and Comet Impacts affected the Religious Beliefs of our Ancestors. It is available through iBooks and Amazon.
This website only lists information on modern-day comets and meteor showers. The book, however, thoroughly investigates how specific ancient impacts and near misses changed religious beliefs around the world.
Panoramic Survey Telescope and Rapid Response System
The primary objective of The Panoramic Survey Telescope and Rapid Response System (“Pan-STARRS” or “PANSTARRS”) on inception was to detect Near Earth Objects (NEOs).
Pan-STARRS consists of an array of cameras, telescopes and computers located on the side of an extinct volcano in Maui. The PS1 Science Consortium funds the operation of the telescope. Break the Consortium down, and you'll find it's composed of ten institutions from four countries.
Pan-STARRS works 24 hours a day, 365 days a year to automatically detect differences in images. Each image is captured by the largest digital camera ever built, and has a resolution of 1.4 billion pixels. It can capture faint objects up to an apparent magnitude of 24. 6,000 square degrees of sky can be mapped nightly, which means Pan-STARRS can survey the sky roughly four times a month. However, only 30,000 square degrees of sky are visible from Hawaii at any particular time of the year.
Pan-STARRS went online on December 6, 2008 and has since detected hundreds of asteroids and comets, including Comet PANSTARRS (C/2011 L4).
