Webb & Hubble find massive star clusters emerge faster

Astronomers using the NASA/ESA/CSA James Webb Space Telescope together with the NASA/ESA Hubble Space Telescope have looked deeply at thousands of young star clusters in four nearby galaxies, studying clusters at different stages of evolution. Their findings show that more massive star clusters emerge more quickly from the clouds they are born in, clearing away gas and filling the galaxy with ultraviolet light. The result gives us a better understanding of star formation in galaxies, as well as how and where planets can form.
