The Bad Astronomer writes: "Using new software techniques on Hubble data from 1998, astronomers have teased out direct images of three planets orbiting the Sun-like star HR 8799, 130 light years away. These planets were discovered in 2008 using a different telescope, but had been sitting in the Hubble pictures this whole time, invisible due to their proximity to the bright star. Many other images of other stars are available, so it's entirely possible more planets will be found in this way."
