This means many of the longer period planets only transit once in the TESS data. However, TESS only scans most sections of the sky for 27 days. This uses the transit method to spot planets, scanning for the telltale dip in light from the star that indicates that an object has passed between the telescope and the star. The planet was originally found in a search for planets in 2018 by the Warwick-led team using data from NASA’s TESS telescope. Reported in Astrophysical Journal Letters, the planet named NGTS-11b orbits a star 620 light-years away and is located five times closer to its sun than Earth is to our own. The planet, the size, and mass of Saturn with an orbit of thirty-five days, is among hundreds of ‘lost’ worlds that University of Warwick astronomers are pioneering a new method to track down and characterize in the hope of finding cooler planets like those in our solar system, and even potentially habitable planets. NGTS-11b is among hundreds of ‘lost’ worlds that can now be rediscovered with the NGTS telescopes using this novel technique.Found thanks to new method pioneered by University of Warwick team designed to spot planets orbiting further out from their star.Discovery of cooler planet brings astronomers closer to finding more worlds in the habitable ‘Goldilocks zone’.The rediscovery of a lost planet could pave the way for the detection of a world within the habitable ‘Goldilocks zone’ in a distant solar system. The very brilliant Moon appears in the center of the picture and the VISTA (right) and VLT (left) domes can also be seen on the horizon. This nighttime long-exposure view shows the telescopes during testing. The Next-Generation Transit Survey (NGTS) is located at ESO’s Paranal Observatory in northern Chile.
