(1548–1600) and their reception by the
Catholic Church were featured in the episode's narrative sequence. The episode begins with Tyson setting off on the "Ship of the Imagination" to discover Earth’s cosmic address within the
Virgo Supercluster and its place in
space and time. As the viewer floats along with him past the planets of the
Solar System, he skims over
Venus; he shows this planet's intense
greenhouse effect, as well as its extremely high temperatures. Then he explores
Jupiter's
Great Red Spot, a hurricane three times the size of Earth, and provides the first comparison showing how Earth's size diminishes when contrasted with the Spot's expanding view. He passes
Voyager 1, the farthest man-made object from Earth, and explains the
Voyager Golden Record and its purpose. Tyson explains how
human sight is limited in the cosmos and, as an example, shows us how extremely dark
rogue planets are "seen" with
infrared sensors. He then examines the
bubble theory, and how the observable universe might be just a bubble in a "never-ending" set of bubbles, analogous to drops of a
waterfall. In an
animated segment of this episode, Tyson discusses the life and vision of the 16th-century Italian philosopher
Giordano Bruno (voiced by
Seth MacFarlane) as the person who championed a much more expansive understanding of the Earth's place in the universe, with the Sun being just one star among all the others. (Tyson subsequently dismisses Bruno's visionary experiences as unscientific, but is sympathetic to the persecution he suffered.) Later, he presents the
history of the Universe on Carl Sagan's
Cosmic Calendar. The episode ends with Tyson's brief speech about Carl Sagan's life and career, and how Sagan inspired him to become an astrophysicist. == Production ==
