ExoplanettalkSpeaker: Brian Reasor

2014-07-10 – July Meeting, Officer for the Meeting: Brian Reasor

Congratulations to everyone attending the July RAC meeting in spite of torrential rain showers. A number of folks jumped into their amphibious  vehicles and made their way downtown to the museum for the meeting.

The presentation for the July meeting was an overview of Exoplanets. The slide-talk and video pulled together Exoplanet topics such as how many are known to exist (1700+) and where they are located (mostly within 500 light years of our sun).

Space Without The Space

Click for larger  This is pretty interesting illustration by Randall Munroe of how much solid surface there is in our solar system.  As best as I can guess the illustration includes the solid surface under liquid bodies.  You can read more at  http://io9.com/a-map-showing-all-the-solar-systems-solid-surfaces-stit-1598999931, a post by George Dvorsky.

 

 
2014 International Sun-Day
Click for largerSeveral Raleigh Astronomy Club members supported the International Sun-Day events at the North of Carolina Museum of Natural Sciences.  

At the start of the event (12 noon) the weather was not at all cooperative with almost 100% cloud cover.  However holes in the clouds began to appear by 2pm and by 3pm we started to get some solar observing in.  The sun was somewhat quite today without a lot of activity / sun spots.  By around 3:30 we were able to start noticing a sun spot near top edge of the sun.

Using Filters to Exploit Light Visually and Photographically

For the May indoor meeting, RAC member Chris Cole had a very interesting presentation on the different planetary filters and their uses.  The presentation used images (from both Chris' personal collection and NASA) to compare the effects of various filters including colored wratten, UV, and IR filters.  He also discussed what types of objects and conditions benefited from using these filters. Chris Cole had many of the filters he talked about and he demonstrated them to the audience. There were a lot of questions and comments from the audience.
