Astronomy is a discipline that is instinctively associated with vision. Since Galileo invented it in 1610, we have been using the telescope to look at stars and planets – one was even launched into space almost thirty years ago (NASA’s Hubble Space Telescope), to gain the best possible pictures of galaxies and nebulas.
Pictures, however, are not just for the eyes. Scientists are increasingly using alternative techniques to investigate images and to detect patterns and anomalies, explore singularities and hidden structures.
