Light pollution map. If interested in astronomy, the last place you want to be is in the Northeast.

GHS Astronomy Club with Dr. Wesney 1976 – Bowman Observatory

Astronomical Society of Greenwich begins. Bowman Observatory is Refurbished. Rededication day 1986.

Film photo I took using only the light from the gibbous moon.

ISS – Shuttle Discovery

2012-Venus Jupiter Conjunction

Comet Hale Bopp 1997 – 5 ¼” Schmidt camera with curved film plate taken at Ward Pound ridge.

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. Lunar Eclipse 2004 Bowman Observatory

Jupiter - IO

Saturn

2012 – Orion Nebula 72 minutes total exposure (2 minute subs)

Whirlpool Galaxy with H-Alpha data

Cygnus

Rare Venus transit of the Sun June 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, 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. Specs:.95 Meter aperture 95 mega pixels (21 modules each with two 2200x1024 pixel CCDs)

34 Orbital Period in days Size Relative to Earth Q0-Q6: May Sep 2010 Jun 2010 Feb 2011Dec 2011 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?)

38 observation Nature 477, (Sept 6, 2011) Information pull?

I encourage you to visit the Bowman Observatory on a public night. Second and Fourth Tuesdays, weather permitting. See my blog on Greenwich Patch : The Night Sky If anyone wants to me for anything Astro… Thanks
