A post thinking about the future of human civilisation and the biggest risks facing the long term survival of our species.
To mark their 40th anniversary, we tell the story of the Voyager missions. Twin spacecrafts launched in 1977 that have travelled further than any human object, out into the depths of interstellar space and are still reaching for the stars.
Prior to 1992 not a single exoplanet was known to exist. Now, here we sit having discovered 3,537 exoplanets in 2,653 planetary systems. Today we explore these strange new worlds.
