The image in the information box above right was made combining data from ESO's Very Large Telescope and the NASA/ESA Hubble Space Telescope.[8] A team of astronomers at Stockholm University, Sweden, and the Geneva Observatory, Switzerland, identified 200 separate clusters of very young, massive stars, many of which are less than 10 million years old.[8] The observations have led the astronomers to conclude that H11 is most likely the result of a merger between a galaxy that is rich in stars and a younger, gas-rich galaxy.[8]
