A comprehensive new study shows that ice sheets once covered Mars and shaped the characteristic valleys.
The resolution of satellite images is so high that it is possible to identify whales – perfect for research in remote regions. Scientists are now working to improve the method.

An active methane seep was first discovered on the seabed just outside close to the US research station McMurdo in Antarctica.
A tsunami warning was issued Tuesday night after a 7.8 magnitude earthquake had struck off Alaska’s southern coast.
Changes in the Arctic Ocean are much more profound than previously thought due to warmer water masses from the south and are already a reality.
The concentration of algae has increased sharply over the past two decades, so that the Arctic Ocean removes more carbon dioxide from the atmosphere.
Less than a third of Antarctica’s wilderness areas are truly untouched and most of the regions with high biodiversity are outside of it.
Beluga groups across the Arctic are much more complex societies than previously thought.
A fossilized jawbone of a baby dinosaur shows that Alaska was the home of these large lizards during the Cretaceous period.
A drilling project in Greenland aims to take a look at the island’s recent climate history by examining the rock under the ice sheet rather than the ice.

While other whales move south in winter, Spitsbergen Greenland whales spend the winter far north under the ice.
The models being created for the future course of Antarctic sea ice have undergone significant improvements, according to a new analysis.
A new study of heavy metals in Alaska’s permafrost soils shows increased amounts and at the same time large gaps in the data situation.
