2015: The Centennial of Einstein's General Theory of Relativity
100 Years of General Relativity
Steve Kocsis, who teaches astronomy at UAS, will present: '100 years of Einstein's General Theory'. The Big Bang, ultimate fate of the Universe, large scale structure of the Universe, expansion of space, red shift, Gravity, black holes, lensing, dark energy and dark matter all emerge from the Einstein Field equations published in 1915. The Universe is mathematical. The equations are abstract. However, Einstein based his work on visual ideas that give insight into 'The mind of God'.

If you think that the Big Dipper is just a simple star grouping, think again. In this fun presentation, you'll learn where the Dipper is and what it's made of, what lies deep within, how to use it to find your latitude, and more. After this program, the Big Dipper will never look the same again.
Steve Kocsis will be "Dr" Steve and share facts such as moon phases and origin.
Cristina, creator of astronomy humor website will share follies such as animals on the moon.
Can you separate truth from fiction.
While Blood Moon is not a scientific term, it is used colloquially to refer to a total lunar eclipse, because a fully eclipsed Moon often takes on a reddish color. So why does the Moon turn red?
A total lunar eclipse happens when the Moon travels through the Earth's umbra, the dark central portion of its shadow, and the Earth blocks all direct sunlight from falling onto the Moon's surface. However, the Moon does not turn completely dark during a total eclipse as part of the sunlight still reaches the lunar surface indirectly, via the Earth's atmosphere.
On January 18th, 2018 a total lunar eclipse will be visible in Juneau.
