Beyond A Year in Space picks up where A Year in Space left off: Scott Kelly’s last day in space and return to Earth. The special also introduces viewers to the next generation of astronauts training to leave Earth’s orbit and travel into deep space.
In 2017, two solar eclipses crossed the planet. Millions were awestruck as the earth, moon, and sun aligned, casting watchers into total darkness. America experienced the most extensive total eclipse, lasting ninety straight minutes, visible along a path pinpointed by NASA scientists.

This is the story of how our solar system will be transformed by the aging sun before coming to a spectacular end in about eight billion years. Astronomers can peer into the far future to predict how it will happen by analysing distant galaxies, stars and even planets in their final moments. In this film, Horizon brings these predictions to life in a peaceful midwestern town that has a giant scale model of the solar system spread out all over the city. As it ages, the sun will bloat into a red giant star, swallowing planets... as well as half the town. The fate of the Earth itself hangs in the balance. How will the solar system end?
The Known Universe takes viewers from the Himalayas through our atmosphere and the inky black of space to the afterglow of the Big Bang. Every star, planet, and quasar seen in the film is possible because of the world's most complete four-dimensional map of the universe, the Digital Universe Atlas that is maintained and updated by astrophysicists at the American Museum of Natural History.
Artificial selection is one example, eyes another, of the well-documented and inescapable process of evolution--change in a population of species over time--by natural selection. These are some of the things that molecules do.
