2008 ozone hole larger than last year
The 2008 ozone hole - a thinning in the ozone layer over Antarctica - is larger both in size and ozone loss than 2007 but is not as large as 2006.   view more (2008-10-08)

Mars Express observes aurorae on the Red Planet
Scientists using ESA's Mars Express have produced the first crude map of aurorae on Mars. These displays of ultraviolet light appear to be located close to the residual magnetic fields generated by Mars's crustal rocks.   view more (2008-11-24)

NASA and USGS Produce Most Detailed Satellite Views of Antarctica
Researchers from NASA and the U.S. Geological Survey (USGS), Golden, Colo., have woven together more than a thousand images from the Landsat 7 satellite to create the most detailed, high-resolution map ever produced of Antarctica. The Landsat Image Mosaic of Antarctica (LIMA) offers views of the coldest continent on Earth in 10 times greater... view more... (2007-03-08)

For the last 30,000 years, our planet has been hit by a constant rain of cosmic dust particles.   view more (2006-07-28)

Lunar Reconnaissance Orbiter's LAMP shedding light on permanently shadowed regions of the Moon
NASA's Lunar Reconnaissance Orbiter (LRO), launched on June 18 of this year, has begun its extensive exploration of the lunar environment and will return more data about the Moon than any previous mission.   view more (2009-09-18)

How fish species suffer as a result of warmer waters
Ongoing global climate change causes changes in the species composition of marine ecosystems, especially in shallow coastal oceans.   view more (2007-01-05)

Venus Express' infrared camera goes filming
An exciting new series of videos from ESA's Venus Express has been capturing atmospheric details of day and night areas simultaneously, at different altitudes.   view more (2007-05-08)

Warm winter also in the Arctic
Central Europe is not the only place where the past, warm winter has caused record temperatures. Unusually mild temperatures also prevented ice formation in the Arctic, specifically in the region around Spitsbergen.   view more (2007-03-30)

ROV discovers Antarctic seafloor fauna
Remotely Operated Vehicles (ROV) remain an efficient technology to uncover the secrets of Antarctic seafloor fauna. As a precursor to the International Polar Year 2007/2008, the current Polarstern expedition conducted by the Alfred Wegener Institute for Polar and Marine research releases short seafloor video clips taken by ROV only a few hours... view more...

Polar clouds take a 'bite' out of meteoric iron
Polar clouds are known to play a major role in the destruction of Earth's protective ozone layer, creating the springtime 'ozone hole' above Antarctica. Now, scientists have found that polar clouds also play a significant role in removing meteoric iron from Earth's atmosphere. Polar clouds have been widely studied in recent years, because of their... view more... (2004-04-14)

Comparing Chimp, Human DNA
Most of the big differences between human and chimpanzee DNA lie in regions that do not code for genes, according to a new study.   view more (2006-10-16)

Research team draws 150-meter ice core from McCall Glacier
A 150-meter ice core pulled from the McCall Glacier in the Arctic National Wildlife Refuge this summer may offer researchers their first quantitative look at up to two centuries of climate change in the region.    view more (2008-07-11)

NASA flies to Antarctica for largest airborne polar ice survey
NASA begins a series of flights Oct. 15 to study changes to Antarctica's sea ice, glaciers and ice sheets. The flights are part of Operation Ice Bridge, a six-year campaign that is the largest airborne survey ever made of ice at Earth's polar regions.   view more (2009-10-09)

The tropics play a more active role than was thought in controlling the Earth's climate
Researchers from the Universitat Aut√≤noma de Barcelona and Durham University (UK) have discovered that a million years ago, global climate changes occurred due to changes in tropical circulation in the Pacific similar to those caused by El Ni√ħo today.   view more (2005-10-12)

Cassini's Visual and Infrared Mapping Spectrometer detects vast polar ethane cloud on Titan
Cassini's Visual and Infrared Mapping Spectrometer (VIMS) has detected what appears to be a massive ethane cloud surrounding Titan's north pole. The cloud might be snowing ethane snowflakes into methane lakes below.   view more (2006-09-15)

Stratospheric ozone chemistry plays an important role for atmospheric airflow patterns
Interactions between the stratospheric ozone chemistry and atmospheric air flow lead to significant changes of airflow patterns from the ground up to the stratosphere.   view more (2008-03-10)

ETH Zurich Develops a Single-chip Microsensor System to Analyse Gases
There are many target application areas envisaged for the gas sensor chip. Air quality in closed rooms can be monitored. The presence of dangerous - even poisonous - substances in the air can be detected, such as benzene from petrol pumps or perchloroethylene from dry-cleaning installations, and warnings can then be issued. Low-cost Mass... view more... (2001-11-14)

Climate scientists spotlight Arctic warming, plight of polar bears
A climate scientist at the University of Chicago and 30 of her colleagues from across North America and Europe are urging the U.S. Fish and Wildlife Service to list the polar bear as a threatened species because global warming is melting its sea-ice habitat.   view more (2006-06-19)

Climate change and life in the Southern Ocean
A ten-week expedition to the Lazarev Sea and the eastern part of the Weddell Sea opens this year's Antarctic research season of the German research vessel Polarstern.   view more (2007-11-28)
