Discovering the Oldest Stars in the Universe with James Webb Space Telescope
| Aspect | Details |
|---|---|
| Discovery | James Webb Space Telescope (JWST) identified some of the oldest spherical groups (globular clusters) in the cosmos. |
| Significance of Clusters | These globular clusters are dense collections of millions of stars, potentially remnants of the earliest stars and formations in the universe. |
| Methuselah Star (HD 140283) | - Location: Approximately 190 light-years away from Earth, near the Milky Way galaxy's boundary in the constellation of Taurus. - Age: Estimated at about 14 billion years, predating the formation of the Milky Way. |
| Composition | Primarily composed of hydrogen and helium, with minimal traces of heavier elements like iron. |
| Insights | Studies published in Astrophysical Journal Letters have determined Methuselah Star's age and provided insights into its energy production mechanisms and evolutionary stages. |
