Astronomers find two exoplanets less dense than candy floss

An international team of astronomers has identified two extraordinarily "puffy" exoplanets, TOI-791 b and TOI-791 c, orbiting a distant star in the Volans constellation. Both planets have a density lower than candy floss, making them among the least dense exoplanets ever discovered. They represent extreme examples of so-called super-puff planets.
