This video shows a zoom from a ground-based image of the region surrounding HAT-P-11, to a close up of the star taken with the NASA/ESA Hubble Space Telescope.
Not visible here is a Neptune-sized planet named HAT-P-11b, which orbits the star. Astronomers have discovered clear skies and steamy water vapour on the planet. It is the smallest planet ever for which water vapour has been detected.
The small bright object next to the star is not the planet in question; in fact it is not a planet at all, but another star.
