Scientists use the old Titius · Bode rule for habitable planets outside our solar system were estimated number found in the Milky Way about billions of star systems can have a livable planet.
Habitable zones around stars with different radii, “hotter” stellar habitable zone radius is larger
According to foreign media reports, the astronomers in the past 20 years exoplanet survey found, with a large number of planets in the Milky Way, almost around every star there are planets. Recently, scientists 250 years ago by the ancient Titius · Bode rule for habitable planets outside our solar system were estimated number of samples to be distributed outside the 151 series multi-planet systems world 228 planets found around third planet in the habitable belt, this is a startling conclusion. If we Titius · Bode rule extended to the Milky Way, it means that almost everywhere in the galaxy is livable planet.
Scientists predict that the basic premise is the planet around the star in a livable bring the temperature of the planet’s surface for the presence of liquid water, researchers from the University of Copenhagen, Jacobson said Kayal According to our statistics, participate in the analysis of samples there may be a considerable part of the planet’s surface liquid water these extrasolar planets. More importantly, the scientists found not only in the many stars of planetary systems, and the number has reached two to six, the future does not rule out the number of planets discovered to have more star systems. Kepler telescope data currently focused on a smaller orbital radius of the large gaseous planets, Earth-like planets observed there is still much room for improvement.
It is noteworthy that this time the scientists used the Titius · wave was given the right to study exoplanets, the law had been used to find Uranus, in addition to the law also implies that the inner planets of the solar system orbit showed a certain arrangement of the law. Because of this, scientists hope to use Titius · Bode rule to study other star systems, and 151 potential star system study found that there are several each stellar system planets, each system has an average of one to three runs to bring the planet livable.
If this method of exoplanet research for the Milky Way, then we can draw startling conclusion: there are billions of stars in the Milky Way have habitable planets in the Milky Way which means that liquid water could be widespread. The study, published in the “Royal Astronomical Society Monthly” on.
