When does Cosmos: A Personal Voyage return?

Cosmos was produced in 1978 and 1979 by Los Angeles PBS member station KCET on a roughly $6.3 million budget. The series is notable for its groundbreaking use of special effects, which allow Sagan to seemingly walk through environments that are actually models rather than full-sized sets. The soundtrack includes pieces of music provided by Greek composer Vangelis, such as Alpha, Pulstar, and Heaven and Hell Part 1.
