Young Suns of NGC 7129
Young suns still lie within dusty NGC 7129 [ legacy/spitzer_n7129/index.html ], some 3,000 light-years away toward the royal constellation Cepheus [ ]. While these stars are at a relatively tender age, only about a million years old, it is likely that our own Sun formed in a similar stellar nursery some five "billion" years ago. Most noticeable in the striking image [ ] are the lovely bluish dust clouds that reflect [ ] the youthful starlight, but the smaller, deep red crescent shapes are also markers of energetic, young stellar objects. Known as Herbig-Haro [ HHintro.html ] objects, their shape and color is characteristic of glowing hydrogen gas shocked by jets [ releases/1995/24/image/a ] streaming away from newborn stars. Ultimately the natal gas and dust in the region will be dispersed, the stars drifting apart [ ] as the loose cluster orbits the center of the Galaxy. NGC 7129 is [ ] about 10 light-years across.
