And No, One in Two Stars Do NOT Have an Earth-Like Planet Around Them.
They have discovered the Kepler planet bonanza (somewhat late).
But, no, sorry. They have mangled the quite reasonable statement that one in every two sun-like stars may have planets per se by conflating planets with Earth-like planets (and Earth-like planets in the habitable zone). Only 54 of the 1200+ planets detected by Kepler were found to be in their stars habitable zone, and of those only two were roughly Earth mass (and a couple of Super Earths like KOI 702.03, visualized above) . There may be a lot more Earth-like planets out there, but not 50% of them having Earth-like worlds based on present data.
