BMAA Monthly Meeting

Visit to the Upper Dublin Planetarium, in Sandy Run Middle School, Dresher, PA.  

Prof. Kim Small will present "Using a Planetarium to Teach The Reason for the Season" - This session will demonstrate how the effects of the cause of the seasons can be visualized in the planetarium facility. Common misconceptions of the cause of the seasons will be discussed. We will explore the four important seasonal dates of equinoxes and solstices under the dome to make sense of seasonal changes based on the sun's path and position in the sky.

Please park in the main parking lot of the school, enter the main doors by the flagpole then follow the signs to the planetarium. Doors will open at 7:30pm.

In addition to our regular agenda items we will have a special presentation by Oleg Shargorodsky, a club member, who will discuss “How to Acquire Remotely.”

The image of the Angel Nebula (NGC 2170) in constellation Monoceros shown here was Acquired remotely, and processed in PixInsight, LRGB+Ha: 24.5 hours by Oleg.

Beginning with an overview of the critical role of infrared observation for Astronomy and Cosmology, NASA’s major platforms are quickly reviewed.  Three of NASA’s space telescopes – Hubble, James Webb, and the upcoming Nancy Grace Roman – are described, with an emphasis on the use of their infrared instruments for ever clearer and deeper views through the cosmos toward the dawn of the universe.  Highlights of their most recent achievements are featured.  Since the 1990s, these telescopes have enabled a revolution in not only astronomy – but also physics on both large and small scales, and cosmology.
