The EXO-BR program was developed by Caucaia Southern Observatory, located in Vargem Grande Paulista city in Sao Paulo, Brazil.

Today the exoplanets search, or so called extrasolar planets -- planets that orbiting another star --  is one of the greatest astronomy research fields for professional and non professional due to the technologies advance and the reducing costs of softwares and equipaments -- computers, CCD devices, mounts, etc.

51 Pegasi Star - A milestone in the astronomical research
First confirmed planet in other solar system
 
Image of 51 Pegasi star October, 1995: two spanish astronomers, Michel Mayor and Didier Queloz based in  Haute   Provence   observatory  in France, announced the confirmation of the first extrasolar planet.

The 51 Pegasi  star,  in  the  Constellation  Pegasus,  the Winged Horse in Greek mythology, holds a planet called 51 Pegasi b, a hot Jupiter planet.

Since the first dicovery was made, about 420 planets, most of them hot Jupiters, was  found  until  February  2010.

Beyond the Earth  based  telescopes,  space  telescope  as  ESA - CoRoT  and  NASA - Kepler   are searching for planets, specially alien Earths.


At this moment no new Earth was found, and search for planets around the stars are extremely hard -- it's like try to found a Fly over the lamp of a lighthouse miles away.
