Are we alone in the Universe? Beyond our Solar System, thousands of exoplanets orbit distant stars — some of them rocky, some covered with oceans, others hidden beneath icy shells. In this video, we explore how scientists search for life beyond Earth, what makes a planet potentially habitable, and why worlds around distant stars may hold the key to one of humanity’s greatest questions. From alien skies and strange suns to the quiet possibility of life elsewhere, this is a journey through modern astronomy and imagination — grounded in real science.
