Today, astronomers continue to unveil the complex chemical composition of star - forming regions by exploring the rich data set collected with the Herschel Space Observatory. (scienceinschool.org)
Detailed studies of the ages and chemical compositions of these stars suggest that the Milky Way has led a relatively quiet existence, forming stars at a rate of a few suns per year for about the last 10 billion years. (solarviews.com)
Sets of spectra from the European Southern Observatory's Very Large Telescope in Chile were used to help estimate the chemical compositions of stars. (sciencedaily.com)
