Black Holes: Searching for the Unknown
There has never been a more exciting time to study one of the most mysterious phenomena in space. This month, The Sky at Night team investigate the science of black holes and discover the incredible techniques being used to uncover their secrets, and even help us answer bigger questions about our universe.\n\nChris meets with Dr Becky Smethurst at the University of Oxford to learn how a black hole forms from the death of a star. He also investigates whether black holes deserve their menacing portrayal in popular culture. He describes what would happen if we got too close to the event horizon and how black holes might actually play a role in lighting up the universe.\n\nMaggie explores how scientists are trying to understand more about black holes by meeting Dr Tessa Baker, who works on LIGO. The Laser Interferometer Gravitational-Wave Observatory is one of the world’s largest physics experiments and is not your usual type of observatory; instead of looking - it listens. The next observation run has just started, and Maggie learns what they are hoping to find.\n\nChris meets with Dr James Nightingale, who has recently discovered one of the largest black holes in space using brand new computational technology and the age-old technique of gravitational lensing. They explore the relationship between black holes and galaxies, as it is thought that within the centre of every galaxy lies a supermassive black hole.\n\nWe visit our in-house stargazing expert, Pete Lawrence, who shows us how to find a black hole in the sky, and Saturn at its brightest and best.\n\nFinally, George Dransfield visits Dr Silke Weinfurtner at her black hole laboratory, where they are simulating features of black holes here on Earth. They use fluid systems to perform experiments to try to determine if phenomena we think occur around black holes could actually happen.\n
