Astronomers have discovered a planetary system that has only gotten stranger the more they have looked at it.
In the southern constellation of Sculptor, a nondescript orange star was flagged by NASA s Transiting Exoplanet Survey Satellite (TESS) after the telescope spotted the tell-tale signs that planets were orbiting around it. TOI-178, as it came to be called, is a bit smaller and dimmer than our Sun. Observations by TESS recorded evidence for transits when the star s light dims slightly as a planet passes in front of it of at least one planet, or perhaps two.
