When we laymen remain speechless with admiration in front of an unexpected object, experts can read how Earths and suns are made, like from coffee grounds.
Indistinct outlines and reddish hues for those who have the right binoculars, the Orion Nebula is above all the nursery of stars closest to us, an open-air maternity ward.
