Galaxy 2MASX J09442693+0429569 imaged by Hubble. This elliptical galaxy has entered a transitional phase from a young, star-forming galaxy to an older, larger, "red and dead" galaxy. Here, two galaxies have collided, exhausting the gases in the surrounding area and stopping the process of star birth. By contrast, as Hubble looks deeper into the Universe, galaxies show much more vigorous star birth. A merger is also predicted to happen between our own Milky Way Galaxy and neighbouring Andromeda in about four billion years.
ATV Albert Einstein is further prepared for launch at Europe's spaceport in Kourou, French Guiana.
When ATV Albert Einstein is ready to fly it will be launched on an Ariane 5 launcher carrying 2380 kg of fuel and 6.6 tonnes of cargo to the International Space Station.
ESA Herschel space observatory image of Andromeda (M31) using both PACS and SPIRE instruments to observe at infrared wavelengths of 70 um (blue), 100 um (green) and 160 um and 250 um combined (red). The image spans approximately 1 x 3 degrees.

The change in ionosphere of Venus during normal solar wind conditions (left) and reduced solar wind activity (right), as observed by ESA’s Venus Express spacecraft in August 2010. The yellow lines show a projection of the solar magnetic field lines as they interact with the ionosphere.
Venus Express follows an elliptical orbit around the planet once every 24 hours, passing within 250 km of the north pole and 66 000 km over the south pole. The observations were made on the nightside of the planet, when Venus Express was within 15 000 km of the centre of the planet. Although the spacecraft only took measurements within two Venus radii, the findings suggest that the ionosphere likely extends to even greater distances during periods of reduced solar wind intensity.
Samples for a test campaign evaluating a new European cover glass adhesive for solar cells. The adhesive is placed between a glass 'sandwich' and subjected to a long duration space simulation, up to 10 000 hours long, to check for darkening due to radiation degradation. Such darkening would result in a loss of light transmission leading to a reduced power output.
In this image from the Envisat satellite, clouds cover the North Sea and sweep down to the strait between Denmark (lower-right corner) and Norway (upper-centre). In the upper-right corner, a thicker blanket of clouds covers south eastern Norway and spreads into Sweden. Located on the Scandinavian Peninsula, Norway is Europe’s northernmost country and is famed for its fjords. Some of these are visible in the image as dark lines between the white and snow-covered land. Near the top of the image, we can see part of Norway’s longest and deepest fjord, the Sognefjord. In the lower-right corner, we can see part of Denmark’s Jutland peninsula, with small and large bodies of water speckling the flat terrain.

Multi-dome lunar base being constructed, based on the 3D printing concept. Once assembled, the inflated domes are covered with a layer of 3D-printed lunar regolith by robots to help protect the occupants against space radiation and micrometeoroids.
