The Nordic Optical Telescope on La Palma, one of the Canary Islands, has detected an exoplanet that is twice the size of Earth. It was spotted as it passed in front of a star. This is the first time that a planet in this category has been spotted by a ground-based telescope.
Until now, finding planets like our Earth has been the work of space-based telescopes. However, the new observations from a remote island could pave the way for more such discoveries by ground-based telescopes.
