Mars is one of the most explored components of the solar system, yet there are always more discoveries to unveil on Earth's planetary neighbor. On Earth we are able to take direct measurements to understand our planet's meteorological activities, but on Mars scientists must use evidence in the landscape to discern this information instead.
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has detected a new exoplanet orbiting a distant star. The newfound alien world, designated TOI-1420 b, has an exceptionally low density. The finding is reported in a paper published September 18 on the pre-print server arXiv.
