As 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.
NASA has an Office of Planetary Protection. It's where the Officer of Planetary Protection works. And that may be the most awesome thing I've heard all week. Goodnight everybody! ...Just kidding. But there really is an Office of Planetary Protection at NASA, and its job is to keep us from irretrievably screwing up interaction between terrestrial life and extra-terrestrial life (or possible extra-terrestrial life). Boing Boing has an article up about the ever-changing job of creating the protocol that we use to avoid horrible science fiction disasters.
