Mars’ north polar ice cap in 3D
Image: This image shows shows part of the ice cap at Mars’ north pole in 3D when viewed using red-green or red-blue glasses. This anaglyph was derived from data obtained by the nadir and stereo channels of the High Resolution Stereo Camera (HRSC) on ESA’s Mars Express during spacecraft orbit 3670. It covers a part […]
Stormy activity at Mars’ icy north pole
Image: This image shows part of the ice cap sitting at Mars’ north pole, complete with bright swathes of ice, dark troughs and depressions, and signs of strong winds and stormy activity. The landscape here is a rippled mix of colour. Dark red and ochre-hued troughs appear to cut through the icy white of the […]
Mars’ north pole in context
Image: This image shows shows the ice cap at Mars’ north pole. The area outlined by the bold white box indicates the area imaged by the Mars Express High Resolution Stereo Camera on 16 November 2006 during orbit 3670. To source
First sighting of hot gas sloshing in galaxy cluster
ESA’s XMM-Newton X-ray observatory has spied hot gas sloshing around within a galaxy cluster – a never-before-seen behaviour that may be driven by turbulent merger events. To source
X-ray and optical view of the Coma galaxy cluster
Image: This image shows the bright, nearby, and massive Coma galaxy cluster in X-ray and optical light, as seen by XMM-Newton ’s European Photon Imaging Camera (EPIC) and the Sloan Digital Sky Survey (SDSS) . Using XMM-Newton to study Coma and another notably massive cluster, Perseus, astronomers spotted the first signs of gas sloshing around in […]
X-ray and optical view of the Perseus galaxy cluster
Image: This image shows the Perseus galaxy cluster – one of the most massive known objects in the Universe – in X-ray and optical light, as seen by XMM-Newton ’s European Photon Imaging Camera (EPIC) and the Digitzed Sky Survey II, respectively. Using XMM-Newton to study Perseus, astronomers spotted the first signs of this hot […]

Earth from Space: Faroe Islands
Video: 00:02:37 This week’s edition of the Earth from Space programme features a Copernicus Sentinel-2 image over the Faroe Islands – located halfway between Iceland and Norway in the North Atlantic Ocean. See also Faroe Islands to download the image. To source
Faroe Islands
Image: The Copernicus Sentinel-2 mission takes us over the Faroe Islands, located halfway between Iceland and Norway in the North Atlantic Ocean. The Faroe Islands are an archipelago made up of 18 jagged islands and are a self-governing nation under the external sovereignty of the Kingdom of Denmark. The archipelago is around 80 km wide […]
Aeolus winds now in daily weather forecasts
ESA’s Aeolus satellite has been returning profiles of Earth’s winds since 3 September 2018, just after it was launched – and after months of careful testing these measurements are considered so good that the European Centre for Medium-Range Weather Forecasts is now using them in their forecasts.

Aerosol spread from Australian fires
Video: 00:00:20 Ferocious bushfires have been sweeping across Australia since September, fuelled by record-breaking temperatures, drought and wind. The country has always experienced fires, but this season has been horrific. A staggering 10 million hectares of land have been burned, at least 24 people have been killed and it has been reported that almost half […]
Australia: like a furnace
Ferocious bushfires have been sweeping across Australia since September, fuelled by record-breaking temperatures, drought and wind. The country has always experienced fires, but this season has been horrific. A staggering 10 million hectares of land have been burned, at least 24 people have been killed and it has been reported that almost half a billion animals […]
