TJO events return in a busy week

The return of the Theodor Jacobsen Observatory open houses and no less than five astronomy-club events highlight a jam-packed astro calendar for the coming week.

Theodor Jacobsen ObservatoryA welcome sign of spring is the return of the open houses at the Theodor Jacobsen Observatory on the University of Washington campus in Seattle. Astronomy talks and observing through the observatory’s vintage 6-inch Brashear telescope on a Warner & Swasey equatorial mount will happen on the first and third Wednesdays of the month from April through September. The first of the year will be this Wednesday, April 5, beginning at 8 p.m.

Observatory director Dr. Ana Larson will talk about the cause of the phases of the Moon as well as eclipses of the Moon and Sun, with an emphasis on this year’s total eclipse of the Sun to be seen as its shadow sweeps a path across the U.S. on August 21. Future talks will be given by UW undergraduates. Volunteers from the Seattle Astronomical Society staff the observatory dome and, if weather permits, pop the roof for a little stargazing.

While these events are free reservations are strongly recommended for the talks, which typically fill the small classroom in the observatory. In fact, reservations are already completely booked for the April 19 open house. A schedule for future talk topics will be posted soon on the observatory website.

Club events

The Olympic Astronomical Society plans its monthly meeting for Monday, April 3 at 7:30 p.m. in room Engineering 117 at Olympic College in Bremerton. Topics will include the solar eclipse, black holes, and a movie from the club’s Camp Delaney Star Party.

The Tacoma Astronomical Society will meet at 7:30 p.m. Tuesday, April 4 in room 175 of Thompson Hall on the University of Puget Sound campus in Tacoma. Guest speaker Stephanie Anderson, co-owner of Cloud Break Optics in Ballard, will talk about astrophotography from the city. The society will also hold one of its public nights at 9 p.m. Saturday, April 8 at the Fort Steilacoom campus of Pierce College. The indoor presentation will be about space exploration. If the weather cooperates they’ll bring out the telescopes for some observing.

The Spokane Astronomical Society’s monthly meeting is set for 7:30 p.m. Friday, April 7 at the planetarium at Spokane Falls Community College. The topic will be all about telescopes: different types, how they work, and reasons to choose one design over another.

The Battle Point Astronomical Association plans a full evening of events for Saturday, April 8, with their BP Astro Kids program about the lives of stars running at 4 p.m. and again at 5 o’clock. Their planetarium show at 7:30 p.m. will look at when galaxies collide. It all happens at their observatory in Battle Point Park on Bainbridge Island.

Astronomy Night at Shorecrest

Shorecrest High School will host an astronomy night at 7 p.m. Tuesday, April 4. Events for all weather are planned with something for the entire family.

Science and beer

We’ll find out if beer and dark matter mix at an OMSI Science Pub on Thursday, April 6 at McMenamins Mission Theater and Pub in Portland. Astrophysicist Alison Crocker from Reed College will highlight the most convincing observations astronomers have made of dark matter. The doors open at 5 p.m. and the program begins at 7 o’clock. There’s a $5 suggested donation.

Take your space medicine

NASA Flight Surgeon David Reyes will give a lecture titled, “Space Medicine: Past, Present, and Future” at 2 p.m. Saturday, April 8 at the Museum of Flight. Reyes will discuss the evolution of space medical capabilities over the years, and how NASA and commercial spaceflight companies might address future medical needs on a human mission to Mars. The talk is free with museum admission.

Planetarium shows galore

In addition to the Battle Point shows noted above, there are several other planetarium programs on the docket for the week. The WSU Planetarium in Pullman has a new show about sky moms that will run at 7 p.m. Friday, April 7, and repeat at 11 a.m. Saturday and 5 p.m. Sunday. The program is about motherhood myths associated with the constellations.

The Pierce College Science Dome is running a show about rockets in which kids can build their own! It runs on Saturdays through May at 12:30 p.m. and again at 2 p.m. Tickets are $6 and are available online.

The Willard Smith Planetarium at Pacific Science Center has a variety of shows daily. Their complete schedule is on our calendar page.
