Stars vary in brightness due to a number of different astrophysical processes. We'll cover the main types, share some examples to monitor in the summertime - with unaided eyes, binoculars, and any size of telescope.

This profusely-illustrated, non-technical talk will provide a gentle overview of astronomy by touching on a wide variety of common misconceptions.

Astronomer Margaret Ikape takes us on a journey through the universe starting with known and familiar things on the Earth and then building up the scale to things in the solar system, the galaxy, the group of galaxies and then the observable universe.
