More than 20,000 high-temperature records have been broken so far this year in the United States. And the heat is especially bad in cities, which are heating up about twice as fast as the rest of the planet.

Time Tells Its Own Story: A Labor Day Fable

Originally published on Mon September 3, 2012 6:06 pm

And this week, astronomers reported on the discovery of a planetary system orbiting such a binary star, two planets orbiting two suns. It's called Kepler-47 after the Kepler planet-hunting mission that spotted it.
