Explanation:
Bright-rimmed, flowing shapes gather near the centre of this rich starfield
toward the boarders of the nautical southern constellations Pupis and Vela.
Composed of interstellar gas and dust, the grouping of light-year sized
cometary globules is about 1300 light-years distant. Energetic ultraviolet
light from nearby hot stars has molded the globules and ionized their bright
rims. The globules also stream away from the Vela supernova remnant which may
have influenced their swept-back shapes. Within them, cores of cold gas and
dust are likely collapsing to form low mass stars, whose formation will
ultimately cause the globules to disperse.
