Greenland in Depth
August 20 - August 30, 2025
Dr. Steve Croft, SETI Institute Senior Astronomer

Topics:

• Is there anybody out there?
  As early explorers journeyed into the polar unknown they were struck by the immense emptiness. Modern astronomy has revealed a vast Universe, in which we, as humans, feel small and utterly alone. However, upon closer observation - life is everywhere in the Arctic. Can the same be said for the universe at large?
• What time is it? Where am I?
  Our journey on the SH Vega is a voyage in both space and time - we’ll change our clocks several times, and cross the Arctic Circle. Learn about the history of timekeeping, time zones, and their connections to the challenges of determining one’s precise position in the vastness of the ocean.
• Expecting the unexpected
  We’re hoping for some spectacular wildlife encounters on this journey. But being “lucky” often involves both serendipity and preparedness. Find out how cutting-edge telescopes like the Allen Telescope Array, enable us to probe the weird and wonderful in the Universe.
• Sailing on cosmic winds
  The Sun brings light and life, even to remote polar regions. But our nearest star is not always as benign as it seems. Learn how stellar activity on other stars can determine whether planets orbiting them are suitable places for life, and how our own Sun could even threaten our way of life here on Earth.
