Messier 19 is a ball of stars (globular cluster) located in the southern constellation Ophiuchus at a distance of 28,700 light-years from Earth. The cluster contains around 300,000 stars and is thought to be 11.9 billion years old. Charles Messier, the 18th century French astronomer, catalogued over 100 galaxies and clusters. Through the telescopes available at the time, comets, nebulae, globular clusters and galaxies appeared just as faint, diffuse blobs. This image was taken by the NASA/ESA Hubble Space Telescope at visible and ultraviolet wavelengths.
