The Orion region is known to be a hotbed of star-formation activity believed to be accompanied by the generation of planets. In his Perspective, Kastner highlights the report by Briceño et al. , who have performed a detailed survey of a region well removed from sites of ongoing star formation. Their results support earlier suggestions that already a few million years after a parent star is formed, the stage is set for planet formation. Variability is established as a distinguishing characteristic of stellar youth.
