The planets could conceivably be covered by a global ocean, and they may well lead the growing list of alien worlds that can host life as we know it.[/background][/color] [color=rgb(51,51,51)][background=rgb(255,255,255)]"These two planets are our best candidates for planets that might be habitable," said Bill Borucki, a space scientist at NASA's Ames Research Center who is the principal investigator for the $600 million Kepler mission.[/background][/color] [color=rgb(51,51,51)][background=rgb(255,255,255)]The two habitable-zone planets, Kepler-62e and Kepler-62f, are part of a five-planet [/background][/color] [color=rgb(51,51,51)][background=rgb(255,255,255)]that lies in the constellation Lyra, within a patch of sky that's been monitored by the Kepler space telescope over the past four years. The Kepler-62 parent star is about two-thirds the size of our own sun and about a fifth as bright. Three of the star's confirmed planets circle the star in orbits so close that they'd be too hot for life. But the e and f planets are considered to lie in a zone where liquid water could exist, a ring of space that's defined as the habitable zone.[/background][/color] [color=rgb(51,51,51)][background=rgb(255,255,255)][b]What would life be like?[/b] Astrobiologists say the fact that the planets are bigger than Earth wouldn't be an obstacle for life.

[/quote] [color=rgb(51,51,51)][background=rgb(255,255,255)] [b]What would life be like?[/b] Astrobiologists say the fact that the planets are bigger than Earth wouldn't be an obstacle for life. In fact, some experts argue that [url="http://www.nbcnews.com/id/34230212/ns/technology_and_science-space/t/super-earths-may-be-superior-fostering-life/"]a super-Earth is more likely to have life[/url] than an Earth-sized planet. "If you and I walked on it, our weight would double," Borucki said. "But my weight has doubled since I was a teenager ... so we could do it."[/background][/color][color=rgb(51,51,51)][background=rgb(255,255,255)] If the planets had atmospheres like Earth's, Kepler-62e's surface temperature would be 86 degrees Fahrenheit (30 degrees Celsius), while Kepler-62f's temperature would be 19 degrees below zero F (-28 degrees C), Borucki said. "You'd see the sun being substantially larger than our sun, because it's so much closer," he said. "But it'd be darker, like walking around on a cloudy day."[/background][/color][color=rgb(51,51,51)][background=rgb(255,255,255)] In their research paper, Kaltenegger and Sasselov assume that Kepler-62e has a slightly cloudier atmosphere than Earth's, and that Kepler-62f has a thick carbon-dioxide atmosphere with a strong greenhouse effect. Without a thick atmosphere, Kepler-62f could get [url="http://www.nbcnews.com/id/49247168/ns/technology_and_science-space/t/weather-mars-surprisingly-warm-curiosity-rover-finds/"]chillier than Mars[/url]. It might even look more like a [url="http://cosmiclog.nbcnews.com/_news/2013/04/17/17799004-mars-vs-europa-are-we-looking-in-the-wrong-place-for-alien-life?lite"]Europa-style iceball[/url] than a [url="http://en.wikipedia.org/wiki/Waterworld"]Kevin Costner-style water world[/url].[/background][/color] [color=rgb(51,51,51)][background=rgb(255,255,255)] [b]Habitable worlds ahead[/b] Kepler-62e and Kepler-62f aren't the first habitable-zone planets to be identified by the Kepler team, and they won't be the last. A year and a half ago, Kepler-22b came to light as [url="http://www.nbcnews.com/id/45554617/ns/technology_and_science-space/t/major-milestone-search-earths-twin/"]the mission's first potentially habitable planet[/url]. It's 2.4 times wider than Earth, which puts it halfway between our planet and Neptune on the size scale. [url="http://www.nbcnews.com/id/48819528/ns/technology_and_science-space/t/two-alien-planets-found-twin-suns/"]Kepler-47c, unveiled last year[/url], is also a habitable-zone planet — but it's 4.6 times wider than Earth, which makes it Neptune-sized.[/background][/color][color=rgb(51,51,51)][background=rgb(255,255,255)] This January, the science team discussed the habitability of another candidate planet, then known as KOI 172.02. The existence of that world has now been confirmed under the name Kepler-69c, with a size that's 1.7 times Earth's width. "Today we can announce that this is a bona fide planet," Thomas Barclay, an astronomer at Ames Research Center, said during Thursday's news conference. [/background][/color][color=rgb(51,51,51)][background=rgb(255,255,255)] Three months ago, Kepler-69c was hailed as [url="http://www.nbcnews.com/id/50414003/ns/technology_and_science-space/t/kepler-may-have-found-most-earth-like-alien-planet-yet/"]potentially the most Earthlike world detected beyond our solar system[/url], but now researchers say Kepler-62e and Kepler-62f could be stronger contenders.[/background][/color][color=rgb(51,51,51)][background=rgb(255,255,255)] There will be more contenders ahead: Borucki said about four dozen of the more than 2,700 candidate planets being tracked by Kepler lie within their stars' habitable zones, and it takes about a year to confirm each candidate's existence through detailed analysis. "We really wish we were faster," he told NBC News. "I really wish we could knock off one a week."[/background][/color][color=rgb(51,51,51)][background=rgb(255,255,255)] Boruckin and his colleagues are poring through the oceans of observations coming in from the Kepler telescope, and although the spacecraft [url="http://www.nbcnews.com/id/50632654/ns/technology_and_science-space/t/nasas-kepler-space-telescope-recovering-glitch/"]has had its problems[/url], he's hoping that the flood of data will continue for years to come.[/background][/color][color=rgb(51,51,51)][background=rgb(255,255,255)] "When you're born a scientist, they leave out the gene for saying, 'We have enough data,'" Borucki joked.[/background][/color]
