EXPLORE THE UNIVERSE'S MOST COMPLEX MYSTERIES IN THE ALL-NEW SEASON OF "NASA'S UNEXPLAINED FILES" RETURNING TO SCIENCE CHANNEL ON TUESDAY, AUGUST 30

-NASA's Unexplained Files returns for its fourth season-

(Silver Spring, MD) The nature of our universe is complex and mysterious. Through space exploration, humankind has witnessed unbelievable occurrences that have remained mostly unresolved... until now. Cameras used by NASA to explore space have, unintentionally, recorded odd incidences that have included enigmatic lights and figures, geysers on a frozen moon, and inexplicable disappearances, among other findings. NASA'S UNEXPLAINED FILES returns Tuesday, August 30 at 9PM to dive deeper into the archives of the world's top space agency along with other firsthand accounts to reveal confounding mysteries from outer space.

"We live in a time where our knowledge of the universe is growing exponentially," said Wyatt Channell, executive producer of the series. "NASA'S UNEXPLAINED FILES explores some of the cosmos' bizarre stories, proving that truth is often stranger than fiction... and not all mysteries can be solved."

NASA'S UNEXPLAINED FILES features astronauts, scientists, and others who attempt to decode abnormalities caught on camera. This season's unexplained files range from chilling sightings to top-secret government missions; the stories include:

· Harvard scientists gaze on in horror as an investigation into an "impossible" star gives them a glimpse of the terrible fate in store for our own planet.

· Declassified documents reveal how NASA was unwillingly dragged into one of the Cold War's most infamous spy missions.

· Forget deep space - astronomers detect a potentially habitable planet tantalizingly close to earth.

· UFO eyewitness reports are a dime-a-dozen - but when the eyewitness is a future US President - the stakes are as big as they get.

NASA'S UNEXPLAINED FILES is produced for Science Channel by Wag TV. For Wag TV, the executive producers are Martin Durkin and Greg Chivers. For Science Channel, Wyatt Channell is executive producer.
