E3 appears to be the first bona fide Galactic old globular cluster where no sign of self-enrichment is found. This suggests that self-enrichment may not be feasible in clusters of such low mass.

Simulations show that the Jovian Ribbon, a wavy, high-contrast feature in Jupiter’s atmosphere near 30°N, can be reproduced with a 35 m/s westward jet.
