Water is essential to life as we know it and over the last 15 years, we have discovered that water is present in surprising places throughout our solar system and beyond. Analysis from the New Horizon’s mission to Pluto strongly suggests that there is a liquid ocean buried on Pluto in spite of the temperatures as cold as -400ºF there.

The Cassini mission to Saturn has discovered water geysers and a likely subsurface ocean on Enceladus. Jupiter’s moon Europa and Ganymede also likely have a buried liquid ocean because of tidal heating effects from Jupiter’s strong gravity.

Closer to home Mars shows signs of having surface oceans during its early existence and large areas of buried ice have been detected. Before it was boiled off by a runaway greenhouse effect, Venus likely has as much water as Earth does now.

Then there is the intense debate as to how Earth acquired its water. Possibilities include bombardment by comets and asteroids and recent evidence suggests that it was incorporated into the Earth during its formation. Overall, it is estimated that the solar system contained as much as 50 times the amount of water present on the Earth and water may be common on exoplanets.

In this talk, we will analyze where water exists in our solar system and beyond and how it got there. We will also discuss the various theories as to how Earth acquired its water. Image caption: Geysers erupting on the surface of Enceladus, photographed by Cassini (NASA/JPL)

October 07 2021 to October 10 2021

An opportunity to meet, trade secrets and perform astrophotography under the darkest skies in the Eastern USA.

Who should attend?

Simply put: Everyone. Very few astrophotographers, regardless of their level, have access to dark skies. We invite you to take advantage of our location to capture images at your own level. Avoid light pollution with us. Come with your own equipment or use ours to shine with your best images.

The registration fee for the four-day Astrophotography Conference 2021 is $300.00 per participant, with a 10% discount for Adirondack Sky Center (ASC) Members.

Events will occur from October 7 - 10, and will be held at the Roll Off Roof Observatory (178 Big Wolf Rd., Tupper Lake - map). The actual times of scheduled events will be provided when you register.
