CNN reports that “NASA’s planet-hunting TESS mission has found its first Earth-size exoplanet,” dubbed HD 21749c, “in a star system only 53 light-years from Earth.” Researchers determined in a study “published in The Astrophysical Journal Letters on Monday” that the planet “completes an orbit of its host star every eight days,” and “the density suggests that the mini-Neptune has a substantial atmosphere.” Lead study author Diana Dragomir said, “There was quite some detective work involved, and the right people were there at the right time.” (Image Credit: NASA)
