Though only about dozen potentially habitable exoplanets have been detected so far, scientists say the universe should be teeming with alien worlds that could support life. The Milky Way alone may host 60 billion such planets around faint red dwarf stars, a new estimate suggests.

Based on data from NASA's planet-hunting Kepler spacecraft, scientists have predicted that there should be one Earth-size planet in the habitable zone of each red dwarf, the most common type of star. But a group of researchers has now doubled that estimate after considering how cloud cover might help an alien planet support life.

We're not alone in the universe -- or so say half of Americans in a new HuffPost/YouGov poll. And a quarter of Americans think that alien visitors have come to Earth.

According to the new survey, 50 percent of Americans think that there is some form of life on other planets, while only 17 percent think that there's not. Another 33 percent said they aren't sure.

Think about it: Millions of people across Brazil spent three weeks relentlessly protesting in the face of a sport that is their religion, their passion, their identity.
