This is an artist’s impression of a young star surrounded by a protoplanetary disk in which planets are forming.

Summary[edit]

Description	English: This is an artist’s impression of a young star surrounded by a protoplanetary disk in which planets are forming. An international team of astronomers have used NASA’s James Webb Space Telescope to provide the first observation of water and other molecules in the highly irradiated inner, terrestrial-planet forming regions of a disk in one of the most extreme environments in our galaxy. These results suggest that the conditions for rocky-planet formation, typically found in the disks of low-mass star-forming regions, can also occur in massive-star-forming regions and possibly a broader range of environments than previously thought.

User comments	Artist’s impression of a baby star still surrounded by a protoplanetary disc in which planets are forming. Using ESO’s very successful HARPS spectrograph, a team of astronomers has found that Sun-like stars which host planets have destroyed their lithium much more efficiently than planet-free stars. This finding does not only shed light on the low levels of this chemical element in the Sun, solving a long-standing mystery, but also provides astronomers with a very efficient way to pick out the stars most likely to host planets. It is not clear what causes the lithium to be destroyed. The general idea is that the planets or the presence of the protoplanetary disc disturb the interior of the star, bringing the lithium deeper down into the star than usual, into regions where the temperature is so hot that it is destroyed.
