ESA’s Mars Express has spotted a rare case of a crater once filled by a lake, revealed by the presence of a delta. The delta is an ancient fan-shaped deposit of dark sediments, laid down in water. It is a reminder of Mars’ past, wetter climate. The delta is in the Eberswalde crater, in the [...]

There is water inside the moon – so much, in fact, that in some places it rivals the amount of water found within the Earth. The finding from a scientific team including Brown University comes from the first-ever measurements of water in lunar melt inclusions. Those measurements show that some parts of the lunar mantle [...]

Raimund Muscheler is a researcher at the Department of Earth and Ecosystem Sciences at Lund University in Sweden. In the latest issue of the journal Science, he and his colleagues have described how the surface water temperature in the tropical parts of the eastern Pacific varied with the sun’s activity between 7 000 and 11 [...]

Thirteen billion years ago our universe was dark. There were neither stars nor galaxies; there was only hydrogen gas left over after the Big Bang. Eventually that mysterious time came to an end as the first stars ignited and their radiation transformed the nearby gas atoms into ions. This phase of the universe’s history is [...]

Geophysical phenomena such as the dynamics of the atmosphere and ocean circulation are typically modeled mathematically by tracking the motion of air or water particles. These mathematical models define velocity fields that, given (i) a position in three-dimensional space and (ii) a time instant, provide a speed and direction for a particle at that position [...]

TECHBREAK: a new foresight initiative led by the European Science Foundation

Three compilations of images from more than half a century of NASA history are available for comment on a section of the photo-sharing site Flickr known as The Commons. Visitors to NASA on The Commons can help tell the photos’ story by adding tags, or keywords, to the images to identify objects and people. In [...]
