The birth of a star is a nebulous thing indeed.
The Orion Nebulae is a stellar nursery: giving birth to new stars in abundance. The condensation of matter to the point where the fusion ignition of hydrogen takes place.
Possibly the remnants of a former supernova: the death of a star brings renewal and continuity. Many of these stars are new to this galaxy, but are older still than the earliest recorded history of man.
From death is born new life. On a timescale beyond our humble human ability to comprehend.
