The Environmental Protection Agency has issued new national standards designating coal ash β€” a nearly ubiquitous byproduct of coal-fired power plants that contains arsenic and lead β€” as nonhazardous waste.

NPR's Christopher Joyce reports that coal-fired power plants produce more than 130 million tons of the coal ash each year, and they have long stored millions of tons of it in giant ponds.

But many of those ponds have failed in recent years, allowing contaminated water to get into rivers and streams, and ultimately into drinking water.

Once Written Off, Kepler Telescope Finds New Planet

An artist's rendering shows the Kepler spacecraft in its new mission profile, called K2. The space telescope has found a new planet outside our solar system.

More than a year after NASA said its Kepler space telescope was beyond repair, the planet-hunting probe has delivered an unlikely find: a planet that's outside our solar system. The find comes after a team worked to find a way to make Kepler productive again, says NASA, calling the find "a comeback."

The space agency says the newly discovered exoplanet is 2.5 times the diameter of the Earth – and that the lead researcher on the project is a graduate student at the Harvard-Smithsonian Center for Astrophysics.
