Major Discovery on Distant Exoplanet Unveiled by Stargazers

Astronomers have discovered terbium, a rare metal, in the atmosphere of exoplanet KELT-9, which is the hottest ever known to humans. The exoplanet is orbiting a star that is 670 light years away from Earth. The discovery was made through a new method of analyzing exoplanets that allows scientists to collect information about the exoplanets and their atmosphere in a far better way than before. The discovery of the rare metal asserts that its atmosphere has a particular mix of elements, contrary to our solar system. The discovery also allows insight into how the exoplanets evolve over time.
