Scientists are reasonably sure that it's a cloudy day on Kepler-7b, a planet that orbits its star about 1,000 light-years away from us.
Using NASA's orbiting space telescopes, researchers publishing in Astrophysical Journal Letters say that for the first time they've been able to make a rudimentary map of the atmosphere of an extrasolar planet.
The team used faint visible light and infrared reflections from Kepler-7b to make their cloud map.
Scientists think they've identified the source of a massive volcanic eruption that occurred in A.D. 1257 and spread telltale traces across the globe.
The culprit in the "mystery eruption" appears to be the Samalas volcano, part of the Mount Rinjani Volcanic Complex on Indonesia's Lombok Island, an international team of scientists publishing in PNAS journal says.
During an experiment, marketing professor Remi Trudel noticed a pattern in what his volunteers were recycling versus throwing in the garbage. He then went through his colleagues' trash and recycling bins at Boston University for more data.
He found the same pattern, says NPR's Shankar Vedantam: "Whole sheets of paper typically went in the recycling, but paper fragments went in the trash."
Same type of paper, different shapes, different bins.
One thing you can say about the diminutive speckled sea louse: it's always on time.
Scientists studying the tiny crustacean, a marine cousin of the wood-louse, found that it runs not one, but two internal clocks. Not only does the creature have a circadian rhythm, or so called "body clock" like most land-dwelling animals, including humans, but it also has a circatidal clock that follows the 12.4-hour cycle of the tide.
