The James Webb Space Telescope has measured the temperature of a rocky exoplanet for the first time, finding that a "cousin" of Earth most likely lacks an atmosphere, researchers said Monday.

Scientists said Monday they have discovered water inside tiny beads of glass scattered across the Moon, suggesting that one day it could be extracted and used by the "explorers of tomorrow".
The Moon was long believed to be dry, but over the last few decades several missions have shown there is water both on the surface and trapped inside minerals.

For a long time it has been suspected that fullerene and its derivatives could form naturally in the universe. These are large carbon molecules shaped like a football, salad bowl or nanotube. An international team of researchers using the Swiss SLS synchrotron light source at PSI has shown how this reaction works. The results have just been published in the journal Nature Communications.
