it offers an opportunity to study phenomena that are difficult to examine in more distant galaxies

Cassini scientists have been watching the moon's south pole since a vortex appeared in its atmosphere in 2012

The fireworks in the Carina region started three million years ago when the nebula's first generation of newborn stars condensed and ignited in the middle of a huge cloud of cold molecular hydrogen

Its glowing edge indicates that it is being photoionized by the hottest stars in the cluster. It has been hypothesized that stars may form inside such dusty cocoons. The top of the Keyhole Nebula, the most prominent feature embedded inside Carina, is on the left. Another Bok globule is in the foreground. Credit for Hubble Image: NASA, ESA, N.
