WASP gives NASA's planetary scientists new observation platform08.02.2014, Science Daily
Scientists who study Earth, the sun and stars have long used high-altitude scientific balloons to carry their telescopes far into the stratosphere for a better view of their targets. Not so much for planetary scientists. That's because they needed a highly stable, off-the-shelf-type system that could accurately point their instruments and then track planetary targets as they moved in the solar system. That device now exists. Europe's oldest footprints uncovered on English coast07.02.2014, Science Daily
The earliest human footprints outside of Africa have been uncovered, on the English coast, by a team of scientists. Their discovery offers researchers an insight into the migration of pre-historic people hundreds of thousands of years ago when Britain was linked by land to continental Europe. Shadowing in Sensor Images: NASA study points to 'infrared-herring' in apparent Amazon green-up07.02.2014, Science Daily
A new NASA study shows that the appearance of canopy greening is not caused by a biophysical change in Amazon forests, but instead by a combination of shadowing within the canopy and the way that satellite sensors observe the Amazon during the dry season. |
