Book Review: Science, Society, and the Search for Life in the Universe

Science, Society, and the Search for Life in the UniverseWhere is our search for life taking us? Or, even simpler, why are we searching? Bruce Jakosky in his book Science, Society and the Search for Life in the Universe considers these questions and many others. However, he shows that searching for answers is almost as difficult as the search itself for life off of Earth.

Image credit: NASANASA has a new article on their site describing one of the technologies going into the mighty James Webb Space Telescope; the successor to the Hubble Space Telescope. They’ve created an array of microshutters which will allow the telescope to dynamically block the light from nearby objects to make distant objects easier to see.

What’s Up this Week: January 22 – January 28, 2007

McNeilMonday, January 22 – Be out early tonight to catch the slender crescent Moon as we begin our journey designed to acquaint you with specific craters. Around midway on the terminator, you will spot a conspicuous old crater called Langrenus. Named for Belgian engineer and mathematician Michel Florent van Langren, this handsome old crater stretches out over 132 kilometers in diameter. Look closely at its walls, they rise above the surface by 1981 meters and the deepest part of the floor drops down below 4937 meters – deeper than Mount Cotacachi in Ecuador is tall. Is the Sun rising over its brilliant east wall? If so, look closely and see if you can spot Langrenus’ central mountain peak rising up 1950 meters. Then get out your skis, because that’s as high as the base elevation in Jackson Hole, Wyoming!

All Was Quiet in the Galactic Centre

Objects at the galactic core. Image credit: IntegralFor a brief time in April 2006, the active region surrounding the supermassive black hole at the heart of the Milky Way settled down. Ten different sources of high energy rays all faded away temporarily, and ESA’s Integral probe was able to capture images of less bright regions, which weren’t completely obscured by the bright objects in their vicinity.
