The discovery of the first exoplanets

On 9 January 1992, astronomers Alex Wolszczan and Dale Frail announced they had discovered the first two exoplanets, or planets outside our solar system, while working at the Arecibo Observatory in Puerto Rico. The two planets orbit a pulsar, a neutron star, 2,300 light-years away, in the constellation Virgo. We now know of the existence of nearly 6,000 exoplanets, but Poltergeist and Phobetor were the first to be confirmed. Rachel Naylor speaks to Alex Wolszczan.Eye-witness accounts brought to life by archive. Witness History is for those fascinated by the past. We take you to the events that have shaped our world through the eyes of the people who were there. For nine minutes every day, we take you back in time and all over the world, to examine wars, coups, scientific discoveries, cultural moments and much more. Recent episodes explore everything from football in Brazil, the history of the ‘Indian Titanic’ and the invention of air fryers, to Public Enemy’s Fight The Power, subway art and the political crisis in Georgia. We look at the lives of some of the most famous leaders, artists, scientists and personalities in history, including: visionary architect Antoni Gaudi and the design of the Sagrada Familia; Michael Jordan and his bespoke Nike trainers; Princess Diana at the Taj Mahal; and Görel Hanser, manager of legendary Swedish pop band Abba on the influence they’ve had on the music industry. You can learn all about fascinating and surprising stories, such as the time an Iraqi journalist hurled his shoes at the President of the United States in protest of America’s occupation of Iraq; the creation of the Hollywood commercial that changed advertising forever; and the ascent of the first Aboriginal MP.(Photo: An artist's impression of the pulsar planet system discovered by Alex Wolszczan in 1992.
