Astronomers have gathered information suggesting that other plants are capable of supporting liquid water. These astronomers used data gathered
by NASA’s Keplar space telescope which already confirmed that 1,000 planets are orbiting stars in the Milky Way.
Danish researcher Steffen Kjaer Jacobsen, from the University of Copenhagen, said: "According to the statistics and the indications we have, a
good share of the planets in the habitable zone will be solid planets where there might be liquid water and where life could exist."
Researchers have used and updated a 250-year-old mathematical concept called the Titius-Bode law, which predicts the spacing of the planets in
the Solar System. Using this information, they have predicted that there are about 228 planets in 151 systems. They believe that thousands of
stars in the Milky Way galaxy are habitable zone planets where surface water and life could exist.
