Star-forming regions of Vela

The Vela star-forming regions encompass all the molecular clouds and ionized gas regions visible in the direction of the southern constellation of Vela, where star formation processes are active. The structures visible in this direction do not form a single physically connected complex but consist of often independent systems located at significant distances from each other, which appear aligned along our line of sight in succession.
