An international team of astronomers has discovered a new gas giant alien world as part of the Next Generation Transit Survey (NGTS). The newly found exoplanet, designated NGTS-12b, is about the size of Jupiter, but more than four times less massive than the solar system’s biggest planet. The finding is reported in a paper published September 22 on arXiv.org.


NGTS is a wide-field photometric survey focused mainly on the search for Neptune-sized and smaller exoplanets transiting bright stars. The project uses an array of small, fully-robotic telescopes at the Paranal Observatory in Chile, operating at red-optical wavelengths. It uses the transit photometry method to find new exoworlds, which precisely measures the dimming of a star to detect the presence of a planet crossing in
