Astronomers have for the first time, visible radiation absorbed by an exoplanet. All the exoplanets so far are only indirectly observed, for example, by looking at the radiation of the star to which the exoplanet orbits around it.

The exoplanet, where the 3.6 m telescope of ESO in Chile, the radiation of write, is 51 Pegasi b, or Bellerophon as the first planet around a normal star runs out of our solar system is traced in the nineties of the previous century. It is the first time that an instrument on the earth radiation in the visible spectrum has captured of an exoplanet. However, there are earlier exoplanets photographed, but this way is an exoplanet that was not previously observed. Normally study astronomers the radiation of stars to see if any changes occur, so that the presence detect planets for their star to move along.

By the radiation, the astronomers of the ESO also an estimate of the size and weight of this exo-planet, just like Jupiter in our solar system a gas giant. He seems larger than Jupiter and half as heavy. The exoplanet is located about 50 light-years from earth.
