Omega Centauri (NGC 5139)
by Sergio Eguivar
Omega Centauri, represents the most massive and brightest stellar system in our Galaxy. Its size spans 150 light years and gathers more than ten million stars which are orbiting its center. It can be seen at naked eye even in suburban skies and is a splendid target for any kind of instrument. Omega Centauri was listed in Ptolemy's catalogue as a star. In 1677 Edmond Halley was the first who described its really nature. Stars in the center are very concentrated and seems to be separated only by 0.1 light years from each other.
