The SWAP instrument on board ESA's Proba-2 sees the Sun, 30 July 2013, at 9:28:57.258 CEST. SWAP (Sun Watcher using Active Pixel System detector and Image Processing) is a small telescope that captures the solar corona at wavelengths corresponding to temperatures of about a million degrees (around 17.1 nanometers).
Bright strips of X-ray data record the slew history of ESA’s XMM-Newton as it moves its focus between different objects in the sky. The image contains information of over 1200 individual slews made between 2001 and 2012, and covers about 62% of the sky. It is a mosaic of 73 178 individual images of 1 x 0.5 degrees and is shown in Galactic projection, with the Galactic plane lying across the centre of the image. The data cover an energy range of 0.2–2 keV.
A number of well-known X-ray sources are seen in the image, including the Vela supernova remnant (the bright white feature at the far right), the Cygnus Loop (far left), Scorpius X-1 (just above the image centre), and the Small and Large Magellanic Clouds (in the south ecliptic pole, within the concentrated region of overlapping slews at the bottom right of the image).
ESA astronaut Luca Parmitano, currently resident on the International Space Station as a member of the Expedition 36 crew, posted this photo. He wrote: "The Mediterranean, the Pleiades and a storm in the distance…"
ATV Albert Einstein docked on 15 June 2013 to Russia’s Zvezda module. ATV-4 was the heaviest payload ever launched by Ariane 5. The propellants pumped from the European ferry are stored in tanks of the Zarya module.
This colour-coded overhead view is based on an ESA Mars Express High-Resolution Stereo Camera digital terrain model of the region to the north of Hesperia Planum, including part of the Tagus Valles. Centred at approximately 4°S / 114°E, the image has a ground resolution of 22 m per pixel. It was taken on 15 January 2013, during orbit 11504.
