How Do We Know There are Other Planets in Our Galaxy?; Picking Your First Object to Image; Tony Gets an Email!

The study of planets around other stars, exoplanets, is a brand new field, one that closely tracks my career as a software engineer in professional astronomy.  I've had the privilege to watch our knowledge about exoplanets explode: in just a few decades, we've gone from not being sure there were other planets around other stars, to knowing how many there are in our galaxy, their types and in some cases, we can guess as to whether life may be present on them.

Let's talk about this as well as Dustin and I discuss what you should think about when imaging your first night sky object.

Oh, and I got an email!
