Latest episode of Photo Evidence examines strongest evidence for life beyond Earth

It is one of science's most important questions: Are we alone in the universe? From the Pacific Coast to the Scottish Highlands, authentic images of unidentified aerial phenomena have been documented for decades. They have sparked questions about advanced technology, secret military programmes, and, above all, the potential for life beyond Earth.Now, as well as video captured on Earth, a new generation of telescopes is gathering chemical signatures of distant worlds - data precise enough to suggest whether life might exist on planets over 120 lightyears away. In the latest episode of the Daily Mail's Photo Evidence, the Daily Mail's Science & Technology Editor, Shivali Best, and Cambridge University's Professor Nikku Madhusudhan, explore the strongest evidence for life beyond Earth.
