Two years ago we showed that this may lead to substantially varying compositions of exoplanets in planetary systems with a different initial inventory of radioactive isotopes: https://t.co/dLMuScl9Bv 6/

Earth could have easily been a «water world» - a planet entirely covered by ocean. A new paper by NCCR-PlanetS scientists in Nature Astronomy (https://t.co/bT8TLTwPMn) explains how the abundance of an Aluminium-isotope likely played a crucial role. THREAD

Planets that form in regions with high levels of aluminum left with dry materials leading to Earth-like planets, while those in aluminum-light environments may stay wet and form ocean worlds. https://t.co/DMOaIYo9nS #2019ES2232
