Star Babies


Star Babies and their Family, no not celebs, but REAL Stars

August 22, 2008—Several generations of stars "pose" for a family portrait amid curtains of clouds in the star-forming region called W5, about 6,500 light-years away.

Using Spitzer data, a team led by Xavier Koenig at the Harvard-Smithsonian Center for Astrophysics found that cavities in W5 do contain ladder-like progressions of stellar generations, with older stars (blue dots) inside the hollows and younger stars (pink and white dots) around the rims.
