Move over, Hubble! NASA's currently in the middle of building Hubble's successor as we speak. The James Webb Space Telescope (JWTS) will help astronomers understand the history of the universe using infrared technology and a mirror coated in 24-karat gold! To discover how these function, read on, and prepare to launch!
An exoplanet that orbits around two stars, known as a circumbinary planet, has recently been discovered by astronomers using the Kepler space telescope. The planet dubbed Kepler-16b has been compared to the planet Tatooine from Star Wars, due to the fact that it has two Suns in its sky.
The following infographic is a comparison of three alien star systems with our own solar system. It shows the distance at which all the known planets orbit around their stars. As of August 10, 2011, 573 extra-solar planets have been identified, but so far the three systems illustrated below are the record holders for having the most planets.
