What was the Star of Bethlehem, a.k.a. the Christmas Star?

December 23, 2016 by DeSantisK

8PM Tonight, Friday December 23, 2015  Recording Available Here
What Was the Star of Bethlehem?

“What cosmic light could have guided the Three Wise Men to the newborn baby Jesus 2,000 years ago? Learn about all the theories in a free webcast today (Dec. 23) by the online Slooh Community Observatory.

During the show, experts in both religion and astronomy will discuss what the famous Star of Bethlehem might have been: Was it an actual star, a comet, a planet or something else? You can watch the webcast at Slooh.com, beginning at 8 p.m. EST (0100 GMT).”  from Space.com [Read more…] about What was the Star of Bethlehem, a.k.a. the Christmas Star?

2016 Geminid Meteors vs. December Full Cold Moon

December 13, 2016 by DeSantisK

This year the Geminid Meteor Shower, traditiononally arguably (Perseid Meteor Shower) the best meteor shower of the year, is expected to peak on the night of December 13 into the morning hours of December 14, accompanied by the December Full Moon. In Pittsburgh the Moon is Full, December 13 at 7:05 PM EST with Moonrise at 5:06 PM EST that evening. This year’s mating of the Full Moon with the peak of the meteor shower is disadvantageous for optimal meteor viewing with the bright moonlight expected to wash out all but the brightest meteors.

Early Evening Meteor Viewing Windows on Wednesday and Thursday Evenings, Before 6 PM and 7 PM , Respectively, Punctuated by Spectacular Moonrises

However in the nights immediately following Geminid peak the Moon rises approximately an hour later each night allowing an early evening window with a moonless sky as shown in the Stellarium. org screen capture diagrams below. The bonus at the end of the Moonless window is the opportunity to see the spectacle of Moonrise in the crisp December air. Native Americans named the December Moon the Cold Moon or the Long Night’s Moon. When the Moon is near the horizon an optical illusion makes it appear even larger. This year, this month’s moon is at perigee or a part of its elliptical orbit when it is closer to the Earth giving it an added boost in size. In recent years these perigee moons have been popularly named Super Moons. The Amateur Astronomers Association of Pittsburgh is not planning a public Geminid Meteor Viewing at the time. Geminid viewing opportunities will improve in 2017 when there will be less competition from Moonlight. [Read more…] about 2016 Geminid Meteors vs. December Full Cold Moon

Light Up the Sky with Stars Lecture with AAAP Member Diane Turnshek

December 5, 2016 by Heather Panek

How far do you have to travel to see the stars clearly? Join lecturer, author, and astronomer Diane Turnshek as she discusses how light pollution not only prevents us from living under a sky bright with stars, but also negatively impacts human health and the environment. Turnshek will examine how innovative science and technology can reverse this steady creep of sky glow, allowing us to view the same star-filled sky that all past generations did.

Time: Doors open at 6 pm, and the program is 7-9 pm.
Location: Carnegie Science Center
Admission: FREE!

Presenter's Photo

Diane Turnshek is a lecturer in the Department of Physics at Carnegie Mellon University and the Department of Physics and Astronomy at the University of Pittsburgh and is a member of the AAAP. She has published hard science fiction with a focus on space colonization and first contact. Her love of both astronomy and science fiction led her to crew the Mars Desert Research Station near Bryce Canyon, Utah in 2012, where she turned her attention to dark sky advocacy. Her fight against light pollution has taken many forms, including giving a TEDxPittsburgh talk. Turnshek is also a 2015 Dark Sky Defender award recipient, recognized by the International Dark-Sky Association for her contribution to light pollution mitigation.
