Researchers from NASA, the SETI Institute, and others, found that there may be as many as 300 million potentially habitable planets in our galaxy alone. And some of these might even be close by, within 30 light-years of our sun. Recommended Videos To come up with the estimate, researchers...

"Habitable Planets for Man" examines and estimates the probabilities of finding planets habitable to human beings, where they might be found, and the number there may be in our own galaxy. The author presents in detail the characteristics of a planet that can provide an acceptable environment fo...
Billions of habitable planets in Milky Way EUROPEAN astronomers hunting for rocky planets with the right temperature to support life estimate there may be tens of billions of them in our galaxy alone. A team said yesterday about 40 percent of red dwarf stars - the most common type in the ...
根据第二段中“A new analysis concludes that roughly half of the galaxy’s sunlike stars host rocky worlds in habitable zones where liquid water could pool or flow over the planets’ surfaces.”可知,银河系中大约一半的类似太阳的恒星都有岩石世界,它们位于可居住地带,液态水可能在这些行星表面聚集或...
Moons around free-flying planets can be habitable The discovery of dozens of free-flying planets (FFPs) in our galaxy has changed understanding of the early evolution of planetary systems and theories of planet formation. These lonely wanderers were probably expelled from their planetary systems by...

Nonetheless, astronomical studies suggest that a large number of habitable planets-are likely to be present within our Galaxy.Lissauer, Jack JAmes Research CenterLissauer J J. How common are habitable planets? Nature, 1999, 402: C11-14.
“On the way to finding Earths, Kepler is telling us a lot about the frequency of Venus-like planets in our galaxy,” said Stephen Kane,lead author of the new paper on Kepler-69c appearing in theAstrophysical Journal Letters. To determine the location of a star’s habitable zone, one mu...
