Hubble is the only telescope that can make this kind of observation because of its sharp resolution, its image stability, and its 24 years in space. "If we imagine a human on the Moon," van der Marel explained, "Hubble's precision would allow us to determine the speed at which the person's hair grows."
-Now that's just showing off. I don't know much about astronomy, but I wonder if there are other discoveries yet to be made with hubble based on how long it's been in action.

Will the James Webb Space Telescope give us new answers right away or will we have to wait years to get comparative data?
