Our Latest RECON Campaign

RECON-final-logos-4-for-web-v2 It’s been over a year since I last posted about RECON (Research and Education Collaborative Occultation Network). From the project web site:

“Have you ever wondered what’s found in the outer reaches of our solar system? It turns out many, many objects orbit the sun out past Neptune. Called trans-Neptunian objects (TNOs), these frozen bodies were formed at the same time as the rest of our solar system – making them close to four and a half billion years old. Determining the sizes of these objects will help us better understand their formation and composition, and could tell us a great deal about the origins of our solar system.”

And:

“To measure the size of a TNO, we use the shadow it casts on Earth as the TNO moves in front of a distant star – an event called an occultation.”

Tonight … well really very early Saturday morning, our network of 14 telescopes at 14 sites that stretch from south of Reno, Nevada, to the California border, will focus our telescopes on a star so faint we probably won’t be able to see it with our eyes … even with a powerful 11 inch wide reflecting telescope. So to even find it we zero in on a field of stars we know the target star will be in the middle of. Then we attach a camera, or in this case a laptop computer and record the image during the window of time that the event is supposed to take place (Early Saturday morning, November 15, from 2:10-2:30AM Pacific Time). Follow the link above to the project web site to learn more about how this works – it includes photos and a video of an occultation (think eclipse – that’s basically what an occultation is).

The project has been so successful that it was just funded to increase the number of sites and telescopes to reach from the Mexican border in the south, to the Canadian border in the north.

Students (mostly middle and high school students) are recruited to be part of the teams of citizen scientists (all of us volunteer) to make the observations, record the data and even help analyze and share the results. Most of the participants are teachers that recruit their own students and community members to be part of the research team.

Here’s a link to a post about tonight’s campaign including photos, maps and charts.

Learning is messy!
