The Strangest Worlds in the Universe (That Actually Exist)

Glass rain blowing sideways at 7,000 km/h. A planet that might be one-third diamond. A moon that sprays its ocean into space. Two suns, iron rain, and a world darker than coal. Every one of them is real, and today Kevin is visiting all of them on the worst-rated spaceship in the galaxy. 🪐 Which world would YOU visit?

The diamond interior is still a hypothesis. • Enceladus: NASA/ESA Cassini (2005–2017) plumes, tiger stripes and E-ring; Postberg et al., Nature (2023), phosphates; JWST (2023) plume of ~10,000 km. • Kepler-16b: Doyle et al., Science (2011); NASA, "almost a real-life Tatooine". • WASP-76b: Ehrenreich et al., Nature (2020), iron rain (ESPRESSO/VLT); Azevedo Silva et al. (2022), barium; Demangeon et al., A&A (2024), possible "glory" (CHEOPS). • TrES-2b: Kipping & Spiegel (2011), reflects less than 1% of incoming light. • 6,000+ confirmed exoplanets: NASA Exoplanet Archive (2025).
