Spiral-like patterns of star formation discovered in old galaxies
Elliptical and Lenticular galaxies (historically referred to as early-type galaxies) are thought to be no longer giving birth to new stars. Now, a team led by astronomers from the Instituto de Astrofísica e Ciências do Espaço (IA) in Portugal has discovered optical spiral features in the outskirts of three nearby early-type galaxies, which points to a still ongoing inside-out growth.
