Researchers using the ESPRESSO instrument on the European Southern Observatory's Very Large Telescope in Chile recently detected a super-heated exoplanet located 640 light years from Earth. Dubbed WASP-76b, the planet is nearly twice the size of Jupiter and orbits a star almost twice the size as the sun. Like Earth's moon, the same side of WASP-76b always faces its star which allows temperatures to climb above 4300 degrees Fahrenheit — hot enough to vaporize iron. Strong winds carry the iron vapor to the planet's cooler side where it condenses in the atmosphere and rains droplets of liquid iron.
