habitable planets

"We really do know that pretty much every star in the sky hosts at least one planet," says astronomer Adam Frank.
So, two centuries worth of waiting. Is that worth investing in? While conventional wisdom would suggest spacecraft technology
The Earth-like planets are the first ones found orbiting an ultracool dwarf star.
Let's take a look at one of the most intriguing of the 1,739 confirmed exoplanets that is both Earth-sized and in the habitable zone of its star. Known only by its catalog number, Kepler-186f, it has no name yet, but we know quite a bit about it already.
In a panel discussion at the Washington headquarters Monday, the agency said it’s highly unlikely we’re alone in the universe. It believes advancements in telescope technology will help confirm the existence of other life on at least one of the 100 million worlds in our galaxy.
NASA Administrator Charles Bolden echoed Hand's sentiment. Just this year, NASA's Kepler Space Telescope picked up on an
A team led by Robert Wittenmyer, of the University of New South Wales in Australia, discovered Gliese 832c by noticing the

NASA's Kepler space telescope has detected 3,845 candidate exoplanets. Astronomers believe there are at least 100 billion
Colonize Mars? Meh. While some space enthusiasts are vying for a chance to create a human colony on the Red Planet, others
So far, Kepler has looked at just a small slice of the Milky Way, discovering 3,538 potential worlds — 104 of them are in
Cowan and colleagues modeled water storage on super-Earths, finding that the heftier gravity would create massive pressure
Although the size of the habitable zone calculated by Leconte is larger than other estimates in the past, it is also much
The scientists were testing a computer model of the climates and biospheres — the overall life — of possible exoplanets. The
Since there are about 150 billion other galaxies in the visible cosmos, this multiplies out to 5,000,000,000,000,000,000,000 planets within the visible universe capable of supporting biological life of some form.
"Human beings have been looking at the stars for thousands of years," said study researcher Erik Petigura, a graduate student
