New Definition Boots Earth Out Of ‘Goldilocks Zone’ for Habitable PlanetsAs researchers sift through reams of data looking for the telltale signs of planets orbiting other stars in our galaxy, special attention is paid to planets in the so-called 'Goldilocks Zone' that could conceivably support life. In the interest of improving and honing the search for Earth-like planets, a team of astronomers led by Penn State University has proposed some changes to the 'Goldilocks Zone' that they think paint a better picture of where life-sustaining planets would orbit in relation to their stars. There's just one problem -- that new definition kicks the Earth's orbit nearly out of the new 'Goldilocks Zone,' meaning that we are all going to have to move to a planet that could support life, as this one clearly can't. Get packing, everyone.Read on...
New Potentially Habitable Exoplanet Discovered in (Relatively Speaking) Nearby Tau Ceti System
Astronomers have discovered five new planets orbiting the nearby star Tau Ceti, and there's even better news -- one of them could potentially support life one day. While there are a couple things to be excited for, that's a big "potentially." What's more, it's not as if "nearby" is not exactly down the block in absolute terms. At just 12 million miles away, though, it's just a stone's throw away, as far as the cosmos are concerned. Considering that we're running out of ways to doom this planet, it's never too early to start looking for a new one to ruin a little farther down the line.Read on...
