The rare metal terbium has been found in an exoplanet’s atmosphere for the first time. The researchers at Lund University in Sweden have also developed a new method for analyzing exoplanets, making it possible to study them in more detail…”Detecting heavy elements in the atmospheres of ultra-hot exoplanets is another step towards learning how the atmospheres of planets work. The better we get to know these planets, the greater chance we have of finding Earth 2.0 in the future,” concludes Nicholas Borsato.
