Wes Astronomers at Green Bank!

This fall as part of the Radio Astronomy class, our majors and MA students had the opportunity to travel to Green Bank Observatory in West Virginia.  After enduring the 9-hour drive each way, we were let loose on the 40-ft telescope and were also allocated a big chunk of time on the 20-meter telescope.  We toured the receiver lab and the operating room for the Green Bank Telescope, and saw some of the new/experimental facilities like the CHIME outrigger.  The students even managed to survive ~36 hours in the National Radio Quiet Zone without their devices and connection to the outside world!  The Green Bank site was peaceful, beautiful, and awe-inspiring, and several of the students saw the Milky Way for the first time.

Return of the Inflatable Planetarium!

Wesleyan’s astronomy department has had a pair of old Starlab inflatable planetariums for many years, but in 2019 we added a new digital planetarium to our arsenal… which we used for only one semester before the pandemic hit and packing dozens of children into close proximity in a little bubble of air started to seem like not such a great idea for a while.  This year, thanks to data on air exchange rates in inflatable planetariums from colleagues in the UK, along with an awesome level of cooperation from our community on wearing masks in the planetarium environment, we were finally able to bring back planetarium presentations for our Middletown community!

This semester we opened the planetarium for several events: a Scout group visit to the observatory, two days’ worth of expeditions to Macdonough School, a planetarium night at the local public library, and one more school visit.  Students in our Astronomical Pedagogy seminar worked all semester to learn how to use the planetarium equipment, to understand developmental expectations and educational standards for children of different ages, to think about the role of storytelling in science communication, and to practice and give each other feedback on their presentations.  The results were awesome!  Kids in grades K-5 learned about gravity, seasons, the day/night cycle, Morse code, and so much more — our students were pros at getting the kids excited to learn more about space.

Sidewalk Science

This semester our Astronomical Pedagogy seminar is doing “Sidewalk Science” in collaboration with Middletown’s Russell Library during the month of October.  We’ve been collecting questions about space from library patrons and Middletown residents, and each week a team of students chalks responses on the sidewalk in front of the library.

Check out our first round of chalkings, and if you’re in the Middletown area, please visit the web form and submit your questions about space!  Photos of the chalkings will be posted on the library’s and observatory’s social media.

Astronomy Department Statement on George Floyd, Racism, and Police Brutality

We are living through a tumultuous moment in our nation’s history: one that has both caused and brought to light a great deal of pain, anguish, and suffering, especially for people of color in the United States.  This moment presents an opportunity to take a stand and renew our commitment to actively work against the racism and violence against people of color that permeates the fabric of our society as well as our scientific community.  We stand in solidarity with the protestors insisting on an end to violence against individuals and communities of color, a dismantling of systemic institutional racism, and reform of police. We unequivocally affirm that black lives matter.  We acknowledge that the impact of recent events, particularly the deaths of George Floyd, Ahmaud Arbery, Breonna Taylor, and countless others, is disproportionately heavy for people of color in our community, and affirm our support and care for those most directly affected by racism and the efforts to combat it.

We acknowledge that, together with all segments of our society, science has contributed and continues to contribute to the history of violence and oppression of Black and Brown Americans.  We acknowledge that systematic barriers to the full participation of scientists of color exist today, woven into the fabric of the field of astronomy, and that we must actively work to dismantle them and create opportunities for scientists of color.  Our community of learning and discovery requires us to actively work to build an anti-racist organization and support our community members that bear the additional burden of inequity in our society.  Here are a few ways that our department pledges to do some of that work in the coming months and years:

– While the physics GRE has always been optional for applicants to our MA program in astronomy, this year for the first time we will not accept scores at all.

– The astronomy faculty are building and expanding upon modules that explicitly weave STEM equity and inclusion and scientific ethics into the astronomy curriculum.  Two examples include the ethics component of Astronomical Pedagogy seminar, which will be expanded this fall, and the CIS321 seminar on STEM equity and inclusion, which will be taught for the third time this fall.  The latter course explicitly encourages students to design evidence-based initiatives to increase STEM equity and inclusion at Wesleyan, in collaboration with existing groups and structures, and includes both logistical faculty support and funding for those efforts.  We welcome and encourage all members of the Wesleyan astronomy community to join us in these endeavors.

– We will reignite the conversations that have taken place in our department as part of our Diversity Journal Club series, which has lapsed for the past two years, to provide a regular departmental forum to discuss issues related to STEM equity and inclusion, particularly anti-racist efforts, and to plan future action we can take as a department.

– We have benefited from discussions in the department of underrepresentation in astronomy which were driven by visiting researchers who spoke to these issues. This academic year, we will seek to bring in a speaker to give a department-wide seminar on anti-racism in astronomy, with appropriate recognition and compensation for their time and expertise.

– We are committed to a sustained community presence, particularly in K-12 schools that serve demographics underrepresented in astronomy, as part of our public outreach in astronomy.  We will also redouble our efforts to invite children and parents of color into our observatory.

– As individuals, we reaffirm our commitment to dismantling racist structures in our broader Wesleyan campus, our home communities, and our families.

We acknowledge that these actions are a small part in an ongoing and evolving effort. Above all, we pledge to educate ourselves, to do the work of becoming a better and more equitable department, and to support and care for the safety and well being of all of our students and colleagues, but especially those most vulnerable to the systematic oppression embedded within science and our broader human society that we have been reminded of so vividly in recent weeks.

Department Holiday Party 2019

As usual, our holiday party was a festive event, thanks to the incredible hard work of Linda Shettleworth and the good spirits of students, faculty and families. The food was great, the company was fabulous and a good time was had by all. It is so much fun for the elders to watch the next generation coming along. The pictures say it all!

Mercury Transit Observed at VVO

Hundreds of students, staff and townsfolk joined us on Foss Hill Monday, Nov. 11, to observe a transit of Mercury. The sky cooperated for the most part and we were treated to a gorgeous view of this rare event. Thanks to Roy, Seth, John Sillasen, and all the Astronomy Dept. staff and students who helped out!

Students Speak at Keck Undergraduate Research Symposium

Wesleyan students and faculty attending the 2019 KNAC Undergraduate Research Symposium at Vassar College.

Eight Wesleyan undergraduates presented results of their summer research to the annual Undergraduate Research Symposium sponsored by the Keck Northeast Astronomy Consortium (KNAC). This year’s symposium was held on October 5 at Vassar College and attended by 125 astronomy students and faculty, primarily from the consortium colleges (Bryn Mawr, Colgate, Haverford, Middlebury, Swarthmore, Vassar, Wellesley, Wesleyan and Williams). KNAC was founded in 1990 to enhance research opportunities for astronomy students at smaller institutions in the northeast by sharing resources. Today it operates a Research Experiences for Undergraduates (REU) program funded by the National Science Foundation through a grant to Wesleyan. Astronomy majors Mason Tea and Rachel Marino and sophomores Alex Henton and Ava Nederlander gave oral presentations of their projects conducted on campus this summer. In addition, astronomy majors Fallon Konow, Hunter Vannier, Gil Garcia and Terra Ganey gave poster presentations of their summer research. The presenters were joined by an equal number of first and second-year students who went to hear the talks, participate in breakout sessions on various astronomical topics and network with potential future colleagues.

Astronomy Grad Student Receives Award from the American Astronomical Society

We are pleased to announce that Jessica Klusmeyer, a second year graduate student in our MA program, received a Chambliss Student Achievement Award from the American Astronomical Society at its 233rd meeting in Seattle, WA in January, 2019. The award recognizes her outstanding poster presentation at the meeting and her ability to discuss the research underlying it with professional astronomers who serve as judges. We note that Jessica was competing in the graduate division against many more senior graduate students enrolled in Ph.D. programs around the country. This is a wonderful achievement and we are very proud of her work and deserved recognition. Jessica’s research poster was entitled “A Deep Search for Five Molecules in the Debris Disk around 49 Ceti”. Her research advisor is Professor Meredith Hughes and she had a number of co-authors, including former Wesleyan post-doctoral fellow Kevin Flaherty.
