Professor Andrew Collier Cameron, of the University of St Andrews and WASP team member, said: “This is the first time we’ve found a pair of giant planets interacting so closely, and it’s exciting to be able to follow their dance from the ground.”
The international team of scientists, which also included scientists from The Open University and University of Warwick, made the discovery using instruments on Earth rather instead of space telescopes.
WASP-148b was identified by a range of instruments installed at the Roque de los Muchachos Observatory in La Palma, Canary Islands.
The star system was then observed with an instrument known as SOPHIE at France’s Observatoire de Haute-Provence.
