AAAP News

The remaining AAAP spring meetings prior to the annual summer hiatus are scheduled for Friday, April 13, 2018 and Friday, May 11, 2018 at the Carnegie Science Center Science Stage.  The speaker presentations are at 7:30 p.m. Weather-permitting look for an announcement on possible rooftop stargazing prior to the speaker presentation. The monthly members business meeting follow the break after the speaker.

Recall the Gravitational Wave announcement 2017 October 16th, the advanced LIGO and Virgo gravitational wave observatories announced the discovery of a new type of gravitational wave signal,  caused by the collision of two neutron stars. The gravitational wave event occurred on 2017 August 17th, and was accompanied by a gamma-ray burst. NASA’s Swift satellite quickly maneuvered to look at the object with its X-ray and UV/optical telescopes. The spacecraft saw no X-rays – a surprise for an event that produced higher-energy gamma rays. Instead, it found a bright and quickly fading flash of ultraviolet (UV) light. This bright UV signal was unexpected and revealed unprecedented details about the aftermath of the collision. The short-lived UV pulse likely came from material blown away by the short-lived disk of debris that powered the gamma-ray burst. The rapid fading of the UV signal suggests that this outflow was expanding with a velocity close to a tenth of the speed of light. The results of the Swift observations were published in the journal Science. The discovery of this powerful wind was only possible using light, which is why combining gravitational waves and light in what is called ‘multi-messenger astronomy’ is so important.

Our April 13, 2018 speaker is Mike Siegel, PhD the Ultra Violet Optical Telescope Lead on the Swift Telescope, recently renamed the Neil Gehrels Swift Telescope. He will talk to us about the Swift Telescope, what it can see, mainly x-ray or higher energies and how it operates. NASA’s Swift mission is dedicated to studying the gamma-ray burst/black hole connection.  In an automatic mode the Swift is able catch gamma ray bursts, as well its three main instruments can be aimed at objects of interest including black holes, comets, bright stars, distant galaxies, etc.

May 11, 2018 brings us Mark Kochte, NASA New Horizons Mission Specialist to talk with us about, Pluto and Beyond.  He will update us on the New Horizons Mission to Pluto and the upcoming invitation to spend New Year’s Day, January 1, 2019 with the NASA’s New Horizons visit to distant  Kuiper Belt Object 2014 Mu69, 44.2 a. u. from the Sun.

Please join us at these presentations, which are free and open to the public.

We wish to extend a warm invitation to university students on break as well as all AAAP members, guests, AAAP Facebook Fans, Wagman Star Party Fans, Mingo Star Party Fans, etc.! There will be a pre-meeting Meet and Greet in the Planetarium Lobby and inside the Planetarium Theater.  The informal show will allow guests to wander into and out of the performance. Roof Star Gazing  will be available, weather-permitting. All this at 6:30 PM  before the 7:30 PM meeting at the Carnegie Science Center Planetarium-Rooftop Observatory, 1 Allegheny Ave, Pittsburgh, PA 15212. Dress to enjoy the fresh air. A warm alternative to the rooftop will be available inside of the planetarium and in the planetarium lobby. The meeting starts at 7:30 PM in the Planetarium. AAAP members remain for the business meeting after the lecture.

Astro Access will be an fascinating lecture on both Space Weather and Astronomy Outreach to the Non-Visual and Autistic Learners  by Anna Voelker, whom some of you may know from Pittsburgh and from her TED talks. Anna Voelker, NASA Space Weather Forecaster and Science Educator specializing in astronomy accessibility, uses 3D printing and theatre games to better the reach of science to children who are blind or on the autism spectrum. Anna’s outreach has spanned Allegheny Observatory, NASA Goddard Space Flight Center, Space Telescope Science Institute, Center of Science and Industry (COSI), and most recently the NASA Kennedy Space Center. Look forward to a lively and fascinating talk about space weather and how astronomy can be accessible and engaging for all. Anna will share videographic data of solar activity and explain its interpretation and implications here on Earth as well as in Space. As part of Anna’s examples of using non-visual means in astronomy outreach there will be a demonstration of a 3D printer courtesy of the Carnegie Scinece Center Fab Lab.  The 3D printer will be tasked to make a tactile globe of the night sky constellations.
