Solar radiation in Spain has increased by 2.3% every decade since the 1980s, according to a study by researchers from the University of Girona and the Federal Institute of Technology (ETH) in Zurich. This increase is linked to the decreased presence of clouds, which has increased the amount of direct radiation reaching us from the Sun.

Medieval chronicles have given an international group of researchers a glimpse into the past to assess how historical volcanic eruptions affected the weather in Ireland up to 1500 years ago.
By critically assessing over 40,000 written entries in the Irish Annals and comparing them with measurements taken from ice cores, the researchers successfully linked the climatic aftermath of volcanic eruptions to extreme cold weather events in Ireland over a 1200-year period from 431 to 1649.
A NASA team delivered in May a sophisticated microwave radiometer specifically designed to overcome the pitfalls that have plagued similar Earth-observing instruments in the past.
Research from the University of Alberta shows CFL players are more likely to value medical tests after concussions compared to university-level players. But the professional athletes were more apt to incorrectly believe it's OK to return to the sport within 24 to 48 hours if they had no symptoms.
NASA's Aqua satellite passed over low pressure System 91L in the Gulf of Mexico and captured infrared imagery that revealed a lot of uplift and strong thunderstorms in the eastern part of the storm despite a poorly organized circulation. NOAA's GOES-East satellite showed the large extent of the low pressure area stretching from Mexico's Yucatan Peninsula to Florida.
By comparing infrared and X-ray background signals across the same stretch of sky, an international team of astronomers has discovered evidence of a significant number of black holes that accompanied the first stars in the universe.
Using data from NASA's Chandra X-ray Observatory and NASA's Spitzer Space Telescope, which observes in the infrared, researchers have concluded one of every five sources contributing to the infrared signal is a black hole.
If you had a time machine that could take you anywhere in the past, what time would you choose? Most people would probably pick the era of the dinosaurs in hopes of spotting a T. rex. But many astronomers would choose the period, four and a half billion years ago, that our solar system formed.
In lieu of a working time machine, we learn about the birth of our Sun and its planets by studying young stars in our galaxy. New work suggests that our Sun was both active and "feisty" in its infancy, growing in fits and starts while burping out bursts of X-rays.
Most skygazers recognize the Orion Nebula, one of the closest stellar nurseries to Earth. Although it makes for great views in backyard telescopes, the Orion Nebula is far from the most prolific star-forming region in our galaxy. That distinction may go to one of the more dramatic stellar nurseries like the Cat's Paw Nebula, otherwise known as NGC 6334, which is experiencing a "baby boom."
DURHAM, N.C. -- Southern California beaches with storm drain diversion systems attract millions more people annually, a new study in the journal Marine Pollution Bulletin shows.
The study looked at whether improving the environmental quality of coastal areas through policy intervention had an effect on the way people use coastal areas. Researchers found a direct correlation between increased attendance and the installation of storm drain diversions at 26 beaches in Santa Monica Bay and Malibu.
Two fires in New Mexico which started within a day of each other continue to plague residents around Santa Fe, New Mexico.

New, fast and accurate algorithm from the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw, based on the mathematical formalism used to model processes accompanying interaction of light with gas planet atmospheres, is a major step towards better understanding of physical and chemical properties of materials' surfaces studied under laboratory conditions.
A flash of light from a stellar outburst has provided a rare look at the 3-D structure of material ejected by an erupting nova.
Astronomers used NASA's Hubble Space Telescope to observe the light emitted by the close double-star system T Pyxidis, or T Pyx, a recurring nova, during its latest outburst in April 2011.
Ice sheet researchers use computer models to simulate how ice sheets will respond to changes in ocean and air temperatures. An advantage of these simulations is that they allow testing of many different climate scenarios, but the models are limited by how accurate the data on ice volume and sub-ice terrain are.
Pebbles and sand scattered near an ancient Martian river network may present the most convincing evidence yet that the frigid deserts of the Red Planet were once a habitable environment traversed by flowing water.
A scientific team led by University of Louisville doctoral student Karen Collins has discovered a hot Saturn-like planet in another solar system 700 light-years away.
Collins announced the discovery of exoplanet KELT-6b Tuesday, June 4, during the American Astronomical Society's national meeting in Indianapolis.
Astronomers caught sight of the planet when it passed in front of, or "transited," its host star—and they've since discovered that the planet resembles one of the most famous and well-studied transiting planets, HD 209458b.
