"Final Frontier": The journey into space, beyond the Earth and out of the solar system is only worth it if you can find somewhere to go. The search for other planets outside our solar system has been a very difficult undertaking. Astronomers have long since theorized the existence of other planets, but it was not until the mid-nineteenth century that they were in a position to conduct further scientific study. Micro-lensing is an effective technique used to detect and identify larger objects passing in front of stars. To date, 347 planets have been discovered, twenty with multi planetary systems. Another method of finding these planets has been through the use of the Hubble Telescope.
