Two Photons Walk Into a Bar…

Logos for 2015 Celebrations

Got a punchline?  Share your wit at the South Bend Science Cafe on January 12, 2015, at 6:00 p.m. at Chicory Cafe in South Bend, IN.  I will be the guest speaker addressing astronomy highlights that dovetail with two celebrations: South Bend’s 150th Anniversary and the 2015 International Year of Light.  The only rules are that the speaker has a 15-minute presentation followed by Q&A, no PowerPoint or slides are allowed, and the speaker must have a beverage in one hand and a microphone in the other.  Among the topics I intend to introduce will be:

  • First Midnight, an elongated star chart of the May 22, 1865, midnight sky that is painted on the crosswalk at Washington and Jefferson Streets.  The stars will appear the same during the sesquicentennial, with a different arrangement of visible planets.
  • Eltanin (labeled in the crosswalk), the brightest star in Draco, which is approximately 150 light years away, and whose light left the star approximately when South Bend was formed and is just now reaching us.
  • SB150 Young Astronomers, a yearlong initiative in which South Bend youths will control research-grade telescopes remotely while learning the night sky locally.  The program is an affiliate of Skynet Junior Scholars, with support from The Summers Group, Project Impact South Bend, NAACP South Bend Branch, and others.  Youths may register in person at the Century Center in South Bend on Monday, January 19, 2015, during the 29th Annual Martin Luther King Jr. Celebration.
  • Dark Sky Advocacy.  As the city expands its Light Up South Bend campaign and as LED lights come into vogue, the shortcomings of blue-rich lighting needs to be part of the dialogue.  Are you using the f.lux app or its equivalent?
  • South Bend River Lights, a piece of installation art that purports to be dark-sky friendly as it lights up the St. Joseph River, the dam, and architectural features.
  •, my rebuilt website (dang hackers), at which I try to promote local astronomy happenings.  Please send me your announcements for items that should be included on the Michiana Astronomy Calendar.

Back to the punchline…send me your best, and I’ll have a frosty beverage for creators of the top three punchlines I receive beforehand.  Hope to see you at Science Cafe.

First Midnight

The Albireo Game

Monday, September 1st, 2014

posted by: bueter

The Albireo GameThe 2014 football clash between Notre Dame and Michigan is dubbed The Albireo Game–well, at least among a few sciency folks.  On the preceding Friday night, Sept. 9, telescopes set up in downtown South Bend, IN, will be targeting the visual binary star Albireo (actually, a triple) in the constellation Cygnus the Swan.

Members of Michiana Astronomical Society Inc. (MAS) and of the University of Notre Dame Department of Physics will ask passers-by to observe the star, judge its prominent colors, and then cast a vote.  Is the star pair Blue & Gold, or Maize & Blue?

We invite you to join us at the intersection of Washington and Michigan Streets to support your team colors.  Proceeds from the campaign will benefit AstroCamp (in Michigan) and Art 2 Science camp (in Notre Dame, IN).   More info is at

Planets around red dwarf.

On Monday, April 21, 2014, astronomer Justin Crepp of University of Notre Dame will be the guest speaker at the Michiana Astronomical Society regular meeting, held at 7 PM in the Lion’s Room of the Mishawaka-Penn-Harris Library at 209 Lincolway East in Mishawaka, IN. Dr. Crepp studies exoplanets, with particular interest in the nearby M-class variety of stars that may harbor earth-like planets. His talk is titled, “The M-dwarf Opportunity: Life Around the Smallest Stars.”

A write-up and details are at There’s also a link to an admittedly-not-printer-friendly poster if you wish to download, print, and post it publicly.

Lunar Eclipse Shadows

Thursday, March 27th, 2014

Penumbra and umbra

Earth casts two shadows

Doing any public outreach for the total lunar eclipse on April 15, 2014?  Yes, the hours are a bit harsh for Michiana observers, with the moon entering the umbral shadow at 1:58 a.m. EDT.  Eclipse maps always depict two circular shadows behind earth, though most people can only discern the darker umbral shadow.

To simulate the pair of shadows cast by the earth you need a source of light that has some dimension, or two separated sources of light.  The Lunar Eclipse Shadows activity illustrates the resultant penumbra and umbra.  If you’re outside with a crowd observing the lunar eclipse, this activity works especially well if you use car headlights.

Is the sun really green?  (The answer will likely surprise you.)  Then why don’t we see green stars?  And how is alcohol relevant to the center of our galaxy?

2014 AstroCamp flyer

AstroCamp is an astronomy adventure for kids ages 9-13 at YMCA Camp Eberhart in Three Rivers, MI. Registration is now open for the 2014 session on July 20-26. It’s a weeklong summer camp with emphasis on learning constellations, getting hands on telescopes, and targeting deep sky objects. Kids also enjoy the regular camp activities on the shore of beautiful Corey Lake. Space (at AstroCamp) is limited.

I invite you to download, post, and distribute the 2014 AstroCamp flyer.

If you are an astronomy buff and want to spend some time–whether a few hours or few days–sharing your passion for the night sky, I encourage you to consider being part of the staff for either day or night portions of AstroCamp.  More information is at

Telescope Viewing at “Sun Rings”

Sunday, February 2nd, 2014

Jupiter's Moons

Plasma waves detected by the Voyager spacecraft have inspired a pairing of the sounds of space and the live music of the Kronos Quartet.  Michiana Astronomical Society Inc. (MAS) is partnering with the DeBartolo Performing Arts Center at Notre Dame for the Kronos Quartet production of Sun Rings on Saturday, March 1, 2014.  Before and after the 7:30 p.m. concert, MAS members will set up telescopes outside DeBartolo to target celestial highlights like Jupiter and its Galilean moons. Come see for yourself the visible wavelengths from a grand denizen of the solar system before heading into the theater to hear the sound extracted from plasma waves detected by the Voyager.  More info and links at

Our 2013 Comet Experience

Sunday, February 2nd, 2014

Buggy Comet Model

Michiana embraces astronomy education and public outreach, and the approach and demise of Comet ISON was an example of such community support. At is a summary of the comet experience, including dry ice comets, all-school assemblies, Google+ Hangouts with astronomers, food and beverage specials, a community treasure hunt, music, and several art exhibits. A linked video, also at, blasts through images from the 2013 Comet Festival.  Choose your own music and crank it during the video.

Thanks to all who supported the celebration of science. Even though we knew and announced up front that the comet may not survive its close encounter with sun, as it did not, adult and student participants alike recognized that’s the nature of the beast and embraced the uncertainty anyway.  Regardless of Comet ISON’s outcome, we learned much about comets and ourselves alike.

Comet Festival Ramps Up

Observing Comet ISON with small telescope

Comet ISON has had a recent outburst, just as the Comet Festival starts to ramp up in South Bend, IN. Today at 6:30 p.m., astronomer Martin Ratcliffe will speak about comets at the PHM Digital Video Theater. See   An avid astrophotographer, Ratcliffe captured ISON’s splintering tail in stunning detail, which he’ll show at the Comet or Bust program.

Much else is happening with the Comet Festival, as suggested by the following links:

I invite you to check in often as the line-up continues to grow.  Some events are underway.  For example, the Potawatomi Zoo has a Tail End of the Season program ( that features the characteristics of tails both for animals and for comets, but their last day of the season is December 1, 2013.

Next up: Over 20,000 students in the South Bend Community School Corporation (SBCSC) have made comet-themed art, of which 10 pieces from each of 33 schools go on display at the Colfax Cultural Center.  Nearly all SBCSC schools had full assemblies ( to introduce the students to Comet ISON.
