Hubble Learns Galactic History From Stars

Facts

• The Milky Way galaxy has at least 150 globular clusters, the nearest of which is about 6,000 light-years away. ^[1]
• Astronomers estimate the ages of globular clusters are between 11.5 to 13.5 billion years. ^[1]
• A more recent program (#13297; PI: Piotto) returned to M30 and other globular clusters in our galaxy, observing the clusters with Hubble’s Wide Field Camera 3. ^[1]
