THE FAINTEST STARS
According to Astronomy Magazine's website, the Hubble Space Telescope has made a discovery that provides clues to the origin and evolution of the universe. It has imaged what Astronomy Magazine describes as "the faintest stars ever seen in a globular cluster." Globular clusters are spherical clusters of hundreds of thousands of stars. The globular cluster that the faint stars were found in is one of the oldest formations in the universe. According to Astronomy Magazine, "'These faint stars will act as clocks,' explains Harvey Richer, leader of the research team that made the discovery." The ages of these newly discovered stars will provide information on how and when globular clusters formed. According to Astronomy Magazine, "'It's a test of the age of the universe,' says Richer. 'We're learning about the timeline of the formation of nature.'"
