Mindful stargazing: not just looking at the stars, but seeing ourselves as a part of them

When was the last time you looked up at the night sky with wide-eyed curiosity and wonder?

In my years as a professional astronomer, I gradually forgot about the magic of looking up at the stars. I got so caught up in ideas, concepts and the technology of stargazing that I stopped looking up. It took moving to a remote island to reawaken in me my passion for the night sky.

In this talk I’ll describe my journey from single-minded research astrophysicist to yoga and mediation teacher, and how I’ve been working to bring the spheres of science and spirituality together through what I call mindful stargazing. I’ll take you on a journey to connect your inner and outer Universe and guide you through some simple practices to (re)discover the magic of the night sky and contemplate our place within the universe.
