Night Vision: Comets and Meteor Showers

April 15th, 2017

Imagine, if you can, back ~5 billion years to the beginnings of the solar system: a giant, diffuse cloud of dust and gas collapsed, resulting in the formation of our solar system and everything in it. Not a very romantic way to put it, but essentially that’s what happened.

But what about everything that didn’t turn into a planet, a dwarf planet, or a Kuiper belt object? What happened to all of the leftovers?

Night Vision: Awesome Aurorae

April 11th, 2017

In two different years, near peak solar activity, I had the good fortune of being able to travel to Yellowknife in the Northwest Territory and then Tromso, Norway in search of the aurora. Conditions tested our little expedition and our gear, but the result was some of the best northern lights full-dome time-lapse footage available in the world.

Night Vision: Mercury

March 31st, 2017

Named for the Roman messenger of the Gods, Mercury is unique among the planets of our solar system. A planet of extremes, its relative proximity to the sun and lack of atmosphere causes enormous differences in temperature on opposite sides of the planet. Smaller than the largest moons in our solar system, it is also considerably more massive.  Its 88 day orbital period is the shortest of any of the planets in our solar system.

What is Mercury made out of? How was it formed? These are some of the subjects we’ll explore, along with discussing the Mariner 10 and Messenger spacecraft which flew by the first planet from the sun, and what they learned there.

Night Vision: Mercury is presented live by Paul Gibbs on Thursday, April 6th and Saturday, April 8th, at 6:45pm in the Hansen Dome Theatre. Tickets are just $2 for the public and free for members of Clark Planetarium.
