Scientists have cracked the case of mysterious cosmic objects dubbed “yellowballs.”
The celestial specks mark the birthplaces of many kinds of stars with a wide range of masses, rather than single supermassive stars, researchers report in the Astrophysical Journal. Wolf-Chase’s team initially thought the balls represented early stage gas bubbles. The stars in the clusters are relatively young, only about 100,000 years old.
