Astronomy Science ~ Kepler again to find a new alien planets. The new world was discovered, called HIP 116454b, is a "super Earth", has a diameter 2.5 times larger and 12 times more massive than Earth. This planet located 180 light years from Earth in the Pisces constellation - close enough to be studied by other instruments, the scientists said.

"Like a phoenix rising from the ashes, Kepler was born again and continue to make discoveries," said study lead author Andrew Vandenburg of the Harvard-Smithsonian Center for Astrophysics said in a statement. Kepler was launched in March 2009 with the mission of 3.5 years to determine how frequently planets like Earth formed around the Milky Way. This vehicle has found nearly 1,000 planets that have been confirmed and about 3,200 other planetary candidates have not been confirmed.

This vehicle discovered planet with the "transit method," seeing signs of fading light of a star caused when a planet passes in the face of its parent star. The work requires exact precision - the ability of the spacecraft was lost in 2013 when two of its four reaction wheels damaged.

Kepler team found a way to increase the stability of Kepler using the subtle pressure of sunlight, then proposed extending the mission called K2. NASA grant K2 mission plan for two years in May this year, but Kepler was first detected HIP 116454b even earlier. Vandenburg and his colleagues - who develop special software to analyze data collected by the spacecraft in a disturbed state - see the transit of a single planet in Kepler observations of the nine-day trial in February.

Astronomers confirmed the discovery of the planet using the HARPS-North spectrograph on the Telescopio Nazionale Galileo in the Canary Islands. HIP density 116454b shows that perhaps the planet is covered by water or a rocky planet that is covered with thick clouds, "mini-Neptune." This planet is located just 8.4 million miles (13.5 million kilometers) from its parent star and completing one orbit every 9.1 days. This planet is too hot to host life as we know it, the researchers said.
