![]() ![]() When a planet passes in front of its star as seen from Earth, the star seems fainter for a short time. The planet was spotted by observing it passing in front of its host star, Lendl says. Because it is so hot, the star appears blue and not yellow-white like the Sun.” Lendl says: “The star is considerably larger and more than two thousand degrees Celsius hotter than our Sun.

This object is one of the most extreme planets we know so far.” Iron melts at such a high temperature, and even becomes gaseous. “Planets like WASP-189b are called “ultra-hot Jupiters”. ![]() ![]() “Based on the observations using CHEOPS, we estimate the temperature of WASP-189b to be 3,200 degrees Celsius. “It takes less than 3 days for it to circle its star, and it is 20 times closer to it than Earth is to the Sun.” Lendl says, “WASP-189b is especially interesting because it is a gas giant that orbits very close to its host star. That makes for infernally hot temperatures, but as lead author Monika Lendl observes, the planet WASP-189b is more extreme than others of its type.

The planet is one and a half times the size of Jupiter, the largest planet in our solar system - and has one side permanently turned towards its burning hot blue star. The planet is 322 light years from Earth in the constellation LIbra. WASP-189b was surveyed by the CHEOPS space telescope - and astronomers believe its surface is a blistering 3,200 Celsius, hot enough to turn iron to gas. The planet has one face turned towards its hot blue star (ESA)Ī new space telescope has caught a glimpse of a planet which astronomers describe as one of the ‘most extreme’ in the known universe. ![]()
