Up until the 1990s, we only knew of the planets in our own solar system. Since then, we have discovered over 300 planets orbiting other stars (extrasolar planets, exoplanets). However, most of these planets were found when scientists observed the effect of the planet's gravity upon their host stars.

Astronomers could not show the world what we wanted most: a visible light picture of a planet around a star like the Sun. That situation changed in November 2008 with a discovery by the Hubble Space Telescope. Join us for the story that begins a new era in our knowledge of planetary systems.
