Astronomy Outreach Curriculum

Hello everyone,

In order to keep track of all of our outreach activities, we have created a wiki page with all of the different lessons that we have written. The wiki page can be accessed from the link provided below. Check back often as we will continue updating the activities! We are hoping to add in pictures, downloadable pdfs, and adding in more potential activities.

Pointing to the Horsehead

While taking the telescope for a shake-down cruise last week, students Pat and Logan obtained these images of the iconic Horsehead Nebula in Orion. Dark clouds of dust are silhouetted against a glowing background of hydrogen gas.

Main item on the night’s list of activities was learning how to create a multi-star pointing model for the telescope. The scope slews automatically to a series of locations in the sky, and at each one, an image is taken with the CCD camera, the stars in the image are automatically identified by software (practically by magic to someone who remembers doing this by hand not so long ago!), and the exact pointing of the scope is computed.

After 20 or so positions in the sky have been mapped in this way the software computes the pointing model. This is a big matrix that maps the telescope mounts drive motors and encoders onto the celestial sphere. It takes care of flexure in the mount, discrepancies in the motor drives, gears, and a host of other factors.

End result?  – we commanded the scope to find the Horsehead Nebula, took a long exposure in the Red filter, and there is was!

If you look at the 4 panels in the image, you’ll notice the at the Horsehead is only visible in certain wavelengths of light, and only with very long exposure times. So being able to point and track is essential

 

Astronomy Outreach Activities

Hello everyone,

I hope that you have all enjoyed the start of the new year and the beginning of a new spring semester. Last semester was great for our astronomy outreach program. We worked closely with Robinson Middle School and with teachers Danielle Sherman, Kelly Sanborn, Cathryn Szymanoski, and Douglas Bishop to perform four astronomy activities with over 100 students. We created astronomy cards to help build student understanding of the relationships between celestial objects and how they compare to everyday items. We assisted classes in creating a physical scale model of the Solar System to help explain the usage of models in science and to illustrate the scale of the Solar System. Finally, we created cardboard tube telescopes, while providing an explanation of how they worked, with the students to use at the Star Party we threw, where students could go out one night and look at the stars and space using their own telescopes and high powered telescopes we provided. I would personally like to thank everyone who helped out to make our semester a success. Thank you Jun, Rigel, Sam, Andy, and Logan for assisting with the activities in the classroom, Prof. Silas Laycock for helping to get everything in motion and providing expertise throughout both in and out of the classroom. Prof. Viktor Podolskiy for assisting at our first outreach activity. Lynne for helping to order all of our supplies. Finally, Dan, thank you for everything you did in the classroom and in our group, enjoy your new school. You will be missed here.

In the new semester, we are striving to continue our efforts in local schools and in the community. We will continue to strengthen our partnership with Robinson Middle School and we hope to find new ways to assist in classroom now that their astronomy unit is over. We additionally will continue searching for more schools to assist with astronomy and physics education. We are hoping to continue hosting star parties and are looking forward to expanding our relationship with the North Shore Amateur Astronomy Club (NSAAC). I look forward to being able to write more posts in the future about everything we do this semester.

The First Star Party

Schueller_students_redlight

A cold night in October 2015 was the first Star Party we had at the Schueller Observatory. I was not sure what to expect, considering I had never been to an observatory prior to this, and I’m new to studying the stars. Nonetheless, I was amazed. Not only is there just a 14″ Celestron telescope, but there is a computer program hooked up to it so we can pinpoint certain stars, moons, galaxies, and more without having to use our own eyes all the time. Granted, we have to calibrate the program before we can use it.IMG_0011Schueller_control_room_peopleIMG_0048

We also had smaller telescopes outside the observatory because there was way too many people present to all fit in the observatory. If we are lucky, we can fit 6 or 7 people in the “outside” portion of the observatory with the telescope, and 2 or 3 more in the heated room with the computer monitors. This night, we had over 25 people, so we had to rotate between exploring the night sky with the Schueller observatory and using the small telescopes in the yard.

I spent most of my time looking at the Moon, since it was the clearest thing in the sky, and the closest to us. It wasn’t a full moon, but it was still about 80 percent visible (obviously 80 percent of the possibly visible portion of the moon, not 80 percent of the entire moon). These two pictures were taken with my iPhone 6 Plus through the eyepiece of one of the small telescopes that were in the yard. They came out a lot better than expected. Hopefully I can get more pictures of more objects on the sky. For now, enjoy these.
