Earth-Sized Worlds Spotted in New Advance for Exoplanets

Astronomers on Tuesday said that for the first time they had spotted two Earth-sized worlds orbiting a Sun-like star, in another big advance in the search for so-called exoplanets.

One of the planets is just three percent bigger than Earth and the other is 13 percent smaller, which would make it a bit tinier than Venus, they reported online in the British science journal Nature.

Nuclear Waste Site Hunt Could Point to Granite

The likely death of a planned nuclear waste site at Nevada's Yucca Mountain has left federal agencies looking for a possible replacement. A national laboratory working for the U.S. Department of Energy is now eying granite deposits stretching from Georgia to Maine as potential sites, along with big sections of Minnesota and Wisconsin where that rock is prevalent.

Three decades after the 1982 Nuclear Waste Policy Act said the federal government would handle disposal of high-level radioactive waste, the United States still has no agreed-upon solution for where and how to dispose of about 70,000 metric tons of it. About 10 percent is from the military's nuclear weapons programs; most of the rest is piling up at commercial reactor sites around the country.
