Congratulations to our Stars at Yerkes colleagues on their selection to the SOFIA Airborne Astronomy Ambassador Program!

NASA's Stratospheric Observatory for Infrared Astronomy, or SOFIA, will become a flying classroom for our Stars at Yerkes outreach educators Lynne Zielinski, Kathy Gustavson, and Marcella Linahan (pictured here L-R in the Yerkes Observatory Morgan Room). 

Lynne Zielinski (National Space Society, Long Grove, Illinois) and Marcella Linahan (Carmel Catholic High School, Mundelein, Illinois) have teamed together, and will fly sometime in early summer. 

Kathy Gustavson (Nicolet High School, Whitefish Bay, Wisconsin) has teamed with Jean Creighton (University of Wisconsin–Milwaukee, Manfred Olson Planetarium, Milwaukee, Wisconsin) to bring the excitement of learning the infrared to their respective institutions.  Their flight on March 26, 2014 is highlighted in a YouTube video seen here.

We could not be happier for our Stars at Yerkes SOFIA Ambassadors - way to go!

Come explore with us! Our next Stars at Yerkes teacher workshop will present a sampler of activities to be presented at our 2015 YAAYS Summer Camp. Hands-on activities and technology based lessons will be integrated to study asteroids and comets. Learn how you can take these lessons and share them with your students and youth groups. 

Workshop will be held at Yerkes Observatory in Williams Bay, Wisconsin.

Registration will begin at 8:30 am. Workshop will be from 9:00 am to 4:30 pm. 

Cost for the workshop is $35.00 and registration is suggested. Registration includes lunch.

Yerkes Public Star Party

Saturday, April 11, 2015

7:30 pm - 9:30 pm

Yerkes Observatory

Fee:  $5.00 per person

$15.00 per family

Even if it is too cloudy to observe, there is much to do. Indoor activities include hands-on activities, presentations, and facility tours. The Yerkes tour features a look at, but not through, the 40-inch Great Refractor within the unheated 90-foot diameter dome.

Participants will say farewell to winter constellations and hello to spring ones. If skies are clear, we will observe both with the unaided eye and through telescopes. Venus dominates the western sky. In the east, giant Jupiter with its four moons steals the show. The very bright constellation Orion and its Great Nebula hang nearby, close to Sirius, the brightest nighttime star. Come to see these and more!

Remember to dress appropriately for standing outdoors on a chilly night, with hats, mittens, scarves, winter coats and sturdy shoes. The cost will be $5 per person, with a maximum of $15 per family. All children must be accompanied by an adult. No pets, please. If you wish, bring your own binoculars, digital cameras on a tripod, or telescope. We can help you to use them.

In the Spotlight

Congratulations to Lynne F. Zielinski!

Lynne has been selected by the National Space Club as the 2013 recipient of the National Space Educator Award!

Stars at Yerkes very own Lynne Zielinski was presented with the National Space Society's National Space Educator Award on March 22, 2013

at the 56th annual Robert H. Goddard Memorial Dinner at the Washington Hilton Hotel in Washington, D.C.

Since 1982, the award has been given annually to secondary school teachers who mentor students in the field of space, science, and technology. Recipients are also given a $1,500 grant and a plaque for their respective school.

"Lynne Zielinski is the first two-time winner in the thirty year history of the National Space Club National Space Educator Award. After being selected in 1988 for exemplary work motivating students to do research by planning and flying experiments on the Space Shuttle, she did not rest on her laurels," said National Space Club Award Chairman Kerry Joels.

"She spent the next quarter century expanding her students' opportunities to participate in space science research, encouraged dozens to pursue science and engineering degrees, and expanded community awareness of space science. Her career is an impressive and exceptional model for a space educator," he added.

Lynne has devoted many hours to coordinate our monthly public star parties, work on our family astronomy nights,

and has been workshop leader for several Stars at Yerkes teacher workshops. Lynne continues to mentor fellow S@Y teachers

and give presentations at conferences like SEEC and so much more.

Congratulations Lynne - We are proud of you!
