The universe just got a little more crowded.

Nearly 100 new exoplanets – planets outside our solar system – have been discovered, scientists announced in a new study published on Thursday.

Using powerful telescopes, exoplanets can be detected as they orbit around their star, which causes a subtle dimming of starlight.

These most recent exoplanets were spotted using Nasa’s Kepler space telescope, now in orbit around the Earth.

Though the spacecraft had a major mechanical failure in 2013, scientists were able to reconfigure it to enable it to keep watching for exoplanets.

“We started out analysing 275 candidates of which 149 were validated as real exoplanets,” said study lead author Andrew Mayo, a PhD student at the Technical University of Denmark. “In turn, 95 of these planets have proved to be new discoveries.”
