A team of scientists has found evidence to suggest that every star in the universe has planets.
"Just the recent 15 years have seen the count of known planets beyond the Solar System rising from none to about 700, but we can expect hundreds of billions to exist in the Milky Way alone," said study co-author Dr Martin Dominik. The team used a technique called gravitational microlensing to pick up the presence of planets of all sizes around distant stars.
Every star twinkling in the night sky plays host to at least one planet, a new study suggests. That implies there are some 10 billion Earth-sized planets in our galaxy.
