Presentation Transcript

  1. July 1969

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

  3. GHS Astronomy Club with Dr. Wesney 1976 – Bowman Observatory

  4. Astronomical Society of Greenwichbegins. Bowman Observatory is Refurbished. Rededication day 1986.

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

  6. 2011-03-07 ISS – Shuttle Discovery

  7. 2012-Venus Jupiter Conjunction

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

  9. Total Solar Eclipse - Aruba 1998

  10. 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

  11. 2011-11-03 Jupiter - IO

  12. Saturn 2011-04-03

  13. 2012 – Orion Nebula 72 minutes total exposure (2 minute subs)

  14. Whirlpool Galaxy with H-Alpha data

  15. Andromeda

  16. Zones keep stars from dominating image of NGC4565 Edge-on galaxy NGC4565

  17. Sagittarius

  18. Cygnus

  19. 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, 2012. If that is clouded out, we’ll have to wait 167 years to see another.

  20. Kepler Telescope Mission

  21. 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)

  22. Dec 2011 Jun 2010 Feb 2011 Q0-Q6: May 2009 - Sep 2010 Kepler candidates as of December 2011 > 2500 planet candidates > 200 ‘Earth like’ Size Relative to Earth Orbital Period in days

  23. Artist depiction - Kepler 22b

  24. 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?)

  25. observation Information pull? Nature477, 142-143 (Sept 6, 2011)

  26. 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 email me for anything Astro… RickBria@optonline.net Thanks
