As the world enters a phase of aggressive competition over untapped ocean floor resources, countries are scrambling to stake their claims. The vast economic potential on offer has made the seabed the ultimate frontier in a new Age of Exploration. China's research vessels in particular have been active in waters right across the globe. Through our exhaustive analysis of huge volumes of Chinese ship tracking data, from sand dredgers to survey vessels, we piece together a puzzle that reveals a new hidden power struggle over increasingly critical submarine resources.

Professor Brian Cox tackles some of the most challenging and intriguing questions facing science. He looks back on a decade of discovery and towards the next space frontier.
Brian believes we are at the start of a new age of space travel, where space flight is on the verge of becoming routine. In this episode, he explores the latest science and takes a new look at his old films and asks: how far can we go in our exploration of the cosmos?

The series is a thorough examination of the infamous UFO cult through the eyes of its former members and loved ones. What started in 1975 with the disappearance of 20 people from a small town in Oregon, ended in 1997 with the largest suicide on US soil and changed the face of modern new age religion forever.
In the first episode, Bonnie Nettles and Marshall Applewhite begin to recruit individuals interested in end-of-the-world Christianity, new age religion, and UFOs - but the disappearance of new members soon drives media attention and family concerns.

Bonnie and Marshall - 'Ti' and 'Do' turn to recording their lessons to teach their followers how to transcend, and the intense rule and check partner system is set-up. The renaming of the members, the haircuts, and the clothing style also are changed to fit an androgynous look.
When Ti is given a cancer diagnosis, the dynamic of the group changes. After Ti dies from cancer in 1985, a distraught Do briefly allows members to visit their families. When the members return, Do becomes more controlling.

The message of the group begins to change and losing identity and group mentality is pushed. With more lockdowns and rules, longtime members of the group begin to question or leave. With no sex permitted with members, Dick Joslyn’s membership in the cult poses problem for Do... leading to a new request for the group.
With dwindling numbers, the group needs a new boost of membership. The Exit begins to be discussed as the Hale-Bopp Comet approaches.

The Hale-Bopp Comet is passing Earth and rumours of a mysterious object following the comet could mean the sign that the Heaven’s Gate community could be looking for. With plans for the Exit, the group members begin saying goodbye to the world. In the aftermath of the suicides, the world and the surviving former followers react.
