A Serious Conversation Under the Stars

Summary
Mark and Ethan observe the night sky from Joshua Tree National Park, California, waiting for a chance to see NEOWISE, a comet visible from Earth only once every 6,800 years. Throughout the video, the two discuss various topics relating to outer space, such as the ever-expanding universe, existence of extraterrestrial life, human advancement and potential colonization of other planets. Near the end of the video, Mark and Ethan gently sing a portion of "SPACE IS COOL" remix.

Trivia

 * The video was recorded on July 22, 2020, when NEOWISE comet was passing over Earth.
