Planetary Delights: A rogue planet is an interstellar body with planetary mass that is not gravitationally bound to any "parent" star or star-like object. The exact process by which rogue planets form is still under debate, but recent observations made with the James Webb Space Telescope may help dispel some of the mysteries surrounding these elusive galactic wanderers.
A Stinky Odyssey: HD 189733 b is a well-known exoplanet discovered in October 2005. The planet has a mass 11.2 percent greater than that of Jupiter and a radius 11.4 percent larger. According to the latest data from the James Webb Telescope, it possesses an atmosphere with rather unusual features.
Through the looking glass: Observations from NASA's Kepler mission ended in 2018, but scientists are still pouring over what it recorded. That data can include information about new solar systems and exoplanets waiting to be discovered, not unlike the seven-planet system NASA uncovered in 2017.
