Total Solar Eclipse - Aruba 1998

Astrophotography appeals to both halves of the brain. The realization of how a lunar eclipse occurs, is balanced by the beauty of the event.

Rare Venus transit of the SunJune 2004 Taken from a Penn State sub campus. I arrived at dawn just in time to click the shutter.

Next Venus transit will be June 5, 2012. If that is clouded out, we’ll have to wait 167 years to see another.

Kepler Telescope Mission

Kepler telescope mission: to find potentially life-supporting planets around other stars. Monitors more than 100,000 target stars using the Transit Method.Star brightness measured at least once every few hours. Can see a light drop of 1/10,000 %. Range of planet detection = 3000 light-years.

Kepler candidates as of December 2011> 2500 planet candidates> 200 ‘Earth like’

Artist depiction - Kepler 22b

Earth-like? • At less than 0.8 Earth radii (0.5 Earth mass) NG Gravity can not hold atmosphere • At about 2 earth radii (8 Earth masses) NG Gravity holds too much – Gas Giant

• Shape of orbit? • Plate Tectonics?• Volcanism?• Moon (Stabilization)and double core?)
