Ideas about time and space are explored in the changes that constellations undergo over time, the redshift and blueshift measured in interstellar objects, time dilation in Albert Einstein's theory of relativity, the designs of both Leonardo da Vinci and spacecraft that could travel near light speed, time travel and its hypothetical effects on human history, the origins of the Solar System, the history of life, and the immensity of space. Propping the curiosity about speed of light, Sagan suggested the possibility from the practical projects of the 20th century by British Interplanetary Society marking the beginning of interstellar travel with the projects named Project Orion and Project Daedalus. Although Project Orion was discontinued as a result of nuclear disarmament treaties, Project Daedalus pioneered the idea of using nuclear fusion rather than fission for a viable interstellar spacecraft. In Cosmos Update, the idea of faster-than-light travel by wormholes (researched by Kip Thorne and shown in Sagan's novel Contact) is discussed.

The journeys of the Voyager probes is put in the context of the Netherlands in the seventeenth century, with a centuries-long tradition of sailing ship explorers, and its contemporary thinkers (such as Constantijn Huygens and his son Christian). Their discoveries are compared to the Voyager probes' discoveries among the Jovian and Saturn systems. Sagan was a member of the Voyager research team, and production of the episode coincided with the probes arriving at Jupiter; at one point, Sagan is filmed receiving one of the first-ever images of one of Jupiter's moons. In Cosmos Update, image processing reconstructs Voyager's worlds and Voyager's last portrait of the Solar System as it leaves is shown.

Sagan discusses comets and asteroids as planetary impactors, giving recent examples of the Tunguska event and a lunar impact described by Canterbury monks in 1178. It moves to a description of the environment of Venus, from the previous fantastic theories of people such as Immanuel Velikovsky to the information gained by the Venera landers and its implications for Earth's greenhouse effect. The Cosmos Update highlights the connection to global warming.

The episode, devoted to the planet Mars, begins with scientific and fictional speculation about the Red Planet during the late nineteenth and early twentieth centuries (H. G. Wells' The War of the Worlds, Edgar Rice Burroughs' science fiction books, and Percival Lowell's false vision of canals on Mars). It then moves to Robert Goddard's early experiments in rocket-building, inspired by reading science fiction, and the work by Mars probes, including the Viking, searching for life on Mars. The episode ends with the possibility of the terraforming and colonization of Mars and a Cosmos Update on the relevance of Mars' environment to Earth's and the possibility of a human mission to Mars.

Carl Sagan teaches students in a classroom in his childhood home in Brooklyn, New York, which leads into a history of the different mythologies about stars and the gradual revelation of their true nature. In ancient Greece, some philosophers (Aristarchus of Samos, Thales of Miletus, Anaximander, Theodorus of Samos, Empedocles, Democritus) freely pursue scientific knowledge, while others (Plato, Aristotle, and the Pythagoreans) advocate slavery and epistemic secrecy. During the episode, Sagan intricately referred the discovery of Shapley supercluster in the aftermath of first world war and correctly gives the students the prediction that astronomers will confirm the existence of exoplanets within their lifetime.

The simple act of making an apple pie is extrapolated into the atoms and subatomic particles (electrons, protons, and neutrons) necessary. Many of the ingredients necessary are formed of chemical elements formed in the life and deaths of stars (such as our own Sun), resulting in massive red giants and supernovae or collapsing into white dwarfs, neutron stars, pulsars, and even black holes. These produce all sorts of phenomena, such as radioactivity, cosmic rays, and even the curving of spacetime by gravity. Cosmos Update mentions the supernova SN 1987A and neutrino astronomy.

Beginning with the separation of the fuzzy thinking and pious fraud of astrology from the careful observations of astronomy, Sagan follows the development of astronomical observation. Beginning with constellations and ceremonial calendars (such as those of the Anasazi), the story moves to the debate between Earth and Sun-centered models: Ptolemy and the geocentric worldview, Nicolaus Copernicus' theory, the data-gathering of Tycho Brahe, and the achievements of Johannes Kepler (Kepler's laws of planetary motion and the first science-fiction novel).

Science documentary about the origins of the universe from one of the original top ballers Carl Sagan himself. Carl Sagan examines the origin, development, and complexity of life on Earth and speculates on the possibility of life developing elsewhere in the universe.

This year marks the 100th anniversary of the adoption of the 19th Amendment to the U.S. Constitution, guaranteeing women the right to vote. “Past, Present, and Future of Women in Space,” is an inspirational program to reflect on the stories and contributions of women in space and STEM through the lens of the past, present, and future. In addition to special guests, you’ll hear from a panel of NASA’s own female “firsts” and pioneers, including astronaut Stephanie Wilson; Clara Ma, NASA’s Curiosity rover naming contest winner; Charlie Blackwell-Thompson, launch director at Kennedy Space Center; and moderator Dr. Christyl Johnson, Deputy Director for Technology and Research Investments at Goddard Space Flight Center.

Science documentary about the origins of the universe from one of the original top ballers Carl Sagan himself. First broadcast in 1980, this is the first episode of the thirteen-part TV series: Cosmos: A Personal Voyage. Written and presented by Carl Sagan, it is, in my opinion, one of the most profound insights into our universe, especially for the time period that it was broadcast. Sagan uses our return to Earth as a jumping off point into human history, traveling to Egypt to share the story of the 3rd-century B.C.E. scientist Eratosthenes's deduction of the size of the Earth. He then takes us to the ancient Library of Alexandria, a location we will return to multiple times throughout the series. IG: https://www.instagram.com/scihustletv/
