In this festive family treat, Chris Packham and Michaela Strachan take viewers on a Christmas adventure to explore some of nature's greatest celestial wonders and winter wildlife.

Journeying through some of the most incredible winter landscapes on Earth, Chris and Michaela uncover secrets of the night sky and animal phenomena that are unique to this time of year. Their quest takes them to the stunning Arabian Desert in Jordan in search of the 'star of Bethlehem' - a rare conjunction of two planets that appear very bright and close together in the night sky - a phenomenon that some astronomers believe could have been the basis for the religious story. Following the desert adventures of the Three Wise Men, Chris and Michaela experience traditional nomadic Bedouin life. They camp under the stars, cook in the sand and learn the importance of conserving the desert's vulnerable wildlife.

Deep in Norway's frozen wilderness, Chris and Michaela go in search of the spellbinding Northern Lights and explore how life thrives in these sub-zero conditions. They go snowmobiling with an indigenous Sami family, learn how Rudolf the Reindeer survives the winter months, discover the clever tactics that sea eagles use to feast and even try their best at husky sledding. Full of festive fun, Chris and Michaela bring the wonder of Christmas nature to everybody's living room. Show less
