European astronomers announced that it has discovered 32 new planets orbiting a star outside our solar system and stated that the findings showed that 40 percent or more of the stars like the Sun have planets like that.

That planets have sizes ranging from about five times the Earth up to five times Jupiter's, they said. A number of other planets have been discovered, and astronomers had promised to announce it later this year. "That last discovery made that the number of planets discovered outside our solar system to about 400,".

The team of astronomers used the HARPS spectrograph (Light Speed Planet Finder High Accuracy) mounted on the 3.6-meter telescope, European Southern Observatory (ESO) in La Silla, Chile. Spectrograph did not describe these planets directly, but scientists can calculate the size and mass to detect small changes in stellar vibrations caused by the gravitational pull of a small planet.

Astronomers want to find planets like Earth because it is the most likely place to sustain life. HARPS has discovered 75 planets orbiting a star 30 different. ESO team did not give detailed explanation about what stars are diorbit by the new planet 32.
