an artist impression of our Milky Way galaxy in its youth

Webb catches distant young galaxy devouring its neighbors

Observations of the tiny Sparkler dwarf galaxy have revealed that it is embedded in a system of ancient star clusters and eagerly feasts on its smaller galactic companions to grow.

This means that the galaxywhich was discovered in the first data of the James Webb Space Telescope (JWST), resembles early cannibals Milky Way which also grew by feeding on smaller galaxies. Thus, the study of this galaxy offers astronomers a unique insight into the evolution of the Milky Way.
