The four stars with confirmed exoplanets located within 100 light-years of the Sun include some exciting exoplanets. Ross 128 b, the second-closest temperate exoplanet to us and the nearest exoplanet around a quiet red dwarf star. Now even surer to be a prime target for the James Webb Space telescope and the ESO’s Extremely Large Telescope, which w...
Absolutely—and any exoplanet-hunting telescope. Stars with a vantage point from which they could see Earth transit the Sun could be priority targets for searches for potentially habitable planets, say the authors. It’s also a reason to explore a region of space that’s so far not been extensively searched for exoplanets—the ecliptic plane, a busy re...
It hasn’t gotten many plaudits, but the eight-year missions been invaluable to astronomy and the search for exoplanets. “Gaia is doing the housekeeping,” said Kaltenegger. “Knowing where the stars really are underpins a lot of the really exciting research because if we know where stars are, where they're going and how they move there are other thin...
