For decades some have suspected that there might be others out there, intelligent beings capable of communicating with us, even visiting our world. It might sound like science fiction, but today scientists from across the globe are scouring the universe for signals from extraterrestrials. Scientists have been searching the cosmos for strange signals like the Lorimer Burst for more than 50 years. The film ends with scientists' latest search for extraterrestial intelligence. Horizon obtained exclusive access to film researchers at the Green Bank Telescope searching for radio signals from Tabby's Star, a star so mysterious that some scientists believe it might be surrounded by a Dyson Sphere, a vast energy collector built by advanced aliens.

Flying through bad weather can be a harrowing experience, and for NASA, it can be doubly unnerving, as violent storms can strike from below the atmosphere or above it. Witness the true power of nature in space and on Earth as astronauts and ground crews battle to overcome the elements, including a severe lightning strike that crippled Apollo 12's computer system, the freezing temps that compromised the Space Shuttle Challenger, and the tempest of space debris that sent a dead satellite on a collision course with the International Space Station.

Double stars are stars that appear to be near each other in the sky, but if they’re gravitationally bound together we call them binary stars. Many stars are actually part of binary or multiple systems. If they are close enough together they can actually touch other, merging into one peanut-shaped star. In some close binaries matter can flow from one star to the other, changing the way it ages. If one star is a white dwarf, this can cause periodic explosions, and possibly even lead to blowing up the entire star.

Dark matter is the biggest mystery of the cosmos. Scientists know that it has been vital to the universe since its birth, and new discoveries reveal that it could create black holes, cause mass extinctions, and might even shape life on Earth itself.

NASA’s next-generation space telescope TESS (Exoplanet Survey Satellite) has begun its search for Earth-like planets belonging to other star systems. How many of these ‘exoplanets’ can host life, and what kind of lifeforms can evolve in these environments?
