Funding crisis could lead to an exodus that would be a blow for British science and national growth On a chilly day in December 1945, Bernard Lovell, a physicist at the University of Manchester, struck out for the Cheshire countryside to study cosmic rays, the streams of high-energy particles that crisscross the universe. Peering at the signals from his army surplus radar, he made an unexpected discovery: radio reflections from the ionised trails of shooting stars. The work marked the birth of radio astronomy at Jodrell Bank. A year later, engineers at the site mounted a radar on the base of a searchlight, providing sweeping access to speeding meteors. When Sputnik launched in 1957, they had just completed the Lovell telescope, the largest radio telescope in the world, the only one capable
