Using satellite data to find areas of thermal updraft to fly gliders is just one of the innovative ideas developed over the week-long 'camp' to help bring Earth observation to the everyday user. In its second year, the App Camp saw 20 developers from 16 countries convene at ESA's ESRIN centre in Frascati, Italy.

Submit your ideas to this year's competition on how Earth observation data can benefit business and society. Entries will be accepted in all nine categories starting tomorrow. The Copernicus Masters - previously known as the GMES Masters - rewards the best ideas for services, business cases and applications based on satellite Earth observation data.

Astronauts aboard the International Space Station (ISS) photographed this striking view of Pavlof Volcano on May 18, 2013. The oblique perspective from the ISS reveals the three dimensional structure of the ash plume, which is often obscured by the top-down view of most remote sensing satellites.

Did A Comet Kill the Dinosaurs?

In a geological moment about 66 million years ago, something killed off almost all the dinosaurs and some 70 percent of all other species living on Earth. Only those dinosaurs related to birds appear to have survived. Most scientists agree that the culprit in this extinction was extraterrestrial, and the prevailing opinion has been that the party crasher was an asteroid.

Earth and Comet PanSTARRS Together

While observing the turbulent outer atmosphere of the Sun, or corona, Solar Terrestrial Relations Observatory B (STEREO-B) gathered a novel view of our home planet and a celestial visitor in the inner solar system. Comet PanSTARRS was visible to the naked eye from Earth's northern hemisphere at the time, though STEREO might have had the better view.

The positions of the planets next month will mean diminished communications between Earth and NASA's spacecraft at Mars.

With data from 73 ice and sediment core monitoring sites around the world, scientists have reconstructed Earth's temperature history back to the end of the last Ice Age.

Looking out at Earth's surface from the International Space Station (ISS), astronauts and cosmonauts frequently observe sunglint highlighting both ocean and inland water surfaces.

NASA's Van Allen Probes mission has discovered a previously unknown third radiation belt around Earth, revealing the existence of unexpected structures and processes within these hazardous regions of space.

The striking coincidences of the asteroid 2012 DA14 flying close to the Earth, and a large meteor crash in Russia's Chelyabinsk region on 15 February, showed again the need for coordinated international efforts to predict, and if necessary, mitigate such threats posed by near-Earth objects in the future.

Close Earth Flyby By Asteroid 2012 DA14

A little-known asteroid will skim past Earth on 15 February, passing just 28 000 km from our planet. The 50 m-diameter chunk of space rock was discovered in last year by ESA-sponsored amateur astronomers in Spain.

A nearby short-duration gamma-ray burst may be the cause of an intense blast of high-energy radiation that hit the Earth in the 8th century, according to new research led by astronomers Valeri Hambaryan and Ralph Neuhauser.

NASA scientists say 2012 was the ninth warmest of any year since 1880, continuing a long-term trend of rising global temperatures. With the exception of 1988, the nine warmest years in the 132-year record all have occurred since 2000, with 2010 and 2005 ranking as the hottest years on record.

Air Quality Suffering in China

Residents of Beijing and many other cities in China were warned to stay inside in mid-January 2013 as the nation faced one of the worst periods of air quality in recent history.

As if space travel was not already filled with enough dangers, a new study out today in the journal PLOS ONE shows that cosmic radiation - which would bombard astronauts on deep space missions to places like Mars - could accelerate the onset of Alzheimer's disease.

Mission Accomplished for Landsat 5

Today the U.S. Geological Survey announced that Landsat 5 will be decommissioned over the coming months, bringing to a close the longest-operating Earth observing satellite mission in history.

New Views of Earth at Night

Scientists unveiled today an unprecedented new look at our planet at night. A global composite image, constructed using cloud-free night images from a new NASA and National Oceanic and Atmospheric Administration (NOAA) satellite, shows the glow of natural and human-built phenomena across the planet in greater detail than ever before.

On Oct. 28, 2011, the Suomi National Polar-orbiting Partnership (NPP) satellite successfully blasted into orbit in a spectacular night launch from Vandenberg Air Force Base, Calif.

New Theory on Earth and Moon Formation

New research, funded by the NASA Lunar Science Institute (NLSI), theorizes that our early Earth and moon were both created together in a giant collision of two planetary bodies that were each five times the size of Mars.

Most researchers imagine the initial oxygenation of the ocean and atmosphere to have been something like a staircase, but with steps only going up.
