==========
Our lonely patch of the sky just got alittle less lonely with theidentification of a rocky, Earth-sizedplanet neighboring the star closest to our own Sun.On August 24th, 2016,researchers announced the exciting news:that they had positively identified aplanet about 1.3 times the size of Earthorbiting the red dwarf star Proxima Centauri,4.2 light-years away.The researchers made the discovery byobserving the star carefully over longperiods of time. They found that onceevery 11.2 days the light from the starshifted ever-so-slightly, a variationcalled the Doppler shift, during whichthe star appeared to be moving towardEarth slightly and then away from Earth slightly.That wobble indicated thepresence of the planet. But it's closenessto us in distance and size isn&...
