The Hubble Space Telescope has recently provided us with some astonishing images of exoplanets orbiting distant stars. This is a departure from the indirect detection of exoplanets by measuring the "wobble" of stars (revealing the gravitational presence of a massive planetary body) or the transit of exoplanets through the line of sight of the parent [...]
