A ground-breaking census of 500 stars, 70 of which are known to host planets, has successfully linked the long-standing "lithium mystery" observed in the Sun to the presence of planetary systems.
Using ESO's successful HARPS spectrograph, a team of astronomers has found that sun-like stars that host planets have destroyed their lithium much more efficiently than "planet-free" stars.

(ESO) New images delve into the heart of a cosmic cloud, called RCW 38, crowded with budding stars and planetary systems.
There, young, titanic stars bombard fledgling suns and planets with powerful winds and blazing light, helped in their devastating task by short-lived, massive stars that explode as supernovae.
In some cases, this energetic onslaught cooks away the matter that may eventually form new solar systems.
Scientists think that our own solar system emerged from such a dramatic environment.
