New techniques for spotting previously hidden planets could reveal whether there is life out there – or not.
Australian scientists are part of a team that has for the first time used a radio antenna to find exoplanets, which means planets beyond our solar system.
Using the world’s most powerful antenna – the Low Frequency Array in the Netherlands (Lofar) – the team has discovered radio signals from 19 distant red dwarf stars.
Four of them are emitting signals that indicate that planets are orbiting them.
