An artistic look at a coronal mass ejection launched towards Earth. The image is based on data collected by the ESA/NASA SOHO space telescope and comprises an extreme-ultraviolet image of the Sun’s disc (not to scale) superimposed on an image of the stormy solar environment. The scene has been processed using the running difference technique.
This image featured in a SOHO ‘The Sun as Art’ portfolio in 2002 and was highlighted as space science image of the week on 6 May 2013.
When we look into the distant cosmos, the great majority of the objects we see are galaxies: immense gatherings of stars, planets, gas, dust, and dark matter, showing up in all kind of shapes. This Hubble picture registers several, but the galaxy catalogued as 2MASX J05210136-2521450 stands out at a glance due to its interesting shape.
This object is an ultraluminous infrared galaxy which emits a tremendous amount of light at infrared wavelengths. Scientists connect this to intense star formation activity, triggered by a collision between two interacting galaxies.
The merging process has left its signs: 2MASX J05210136-2521450 presents a single, bright nucleus and a spectacular outer structure that consists of a one-sided extension of the inner arms, with a tidal tail heading in the opposite direction, formed from material ripped out from the merging galaxies by gravitational forces.
The image is a combination of exposures taken by Hubble’s Advanced Camera for Surveys, using near-infrared and visible light.

Korea’s Kompsat-2 satellite captured this image over the sand seas of the Namib Desert on 7 January 2012. The blue and white area is the dry river bed of the Tsauchab. Black dots of vegetation are concentrated close to the river’s main route, while salt deposits appear bright white. Running through the river valley, a road connects Sossusvlei to the Sesriem settlement. At the road’s 45th kilometre, seen at the lower-central part of the image, a white path shoots off and ends at a circular parking area at the base of a dune. This is Dune 45, a popular tourist stop on the way to and from Sossusvlei. In this image, there appears to be some shadow on the western side. From this we can deduce that the image was acquired during the late morning.
ESA supports Kompsat as a Third Party Mission, meaning it uses its ground infrastructure and expertise to acquire, process and distribute data to users.

The environment at the centre of our Milky Way Galaxy. The Galactic Centre hosts a supermassive black hole in the region known as Sagittarius A*, or Sgr A*, with a mass of about four million times that of our Sun.
A dense torus of molecular gas and dust surrounds the Galactic Centre and occupies the innermost 15 light-years of our Galaxy. Enshrouded within the disc is a central cavity, with a radius of a few light-years, filled with warm dust and lower density gas.Part of this gas is being heated by the strong ultraviolet radiation from massive stars that closely orbit the central black hole. Heating also likely results from strong shocks, generated as gas orbits around or flows towards Sgr A*, in collisions between gas clouds or in material flowing at high velocity from stars and protostars.
The remote Antarctic base Concordia enjoying its last sunset for almost four months.
ESA sponsors a medical research doctor in Concordia every winter to study the long-term effects of isolation.
The base is 3200 m above sea level and temperatures drop to –80°C. No supplies can be delivered during the Antarctic winter and nobody can leave the base, no matter what emergency.
The station is the closest thing on Earth to interplanetary exploration. Studying the effects of isolation there is preparing ESA for the real thing: a mission to Mars.
The second flight of ESA’s newest launch vehicle has been completed from Europe’s Spaceport in Kourou, French Guiana. Two Earth observation satellites, ESA’s Proba-V and Vietnam’s VNREDSat‑1A, were released into different orbits, demonstrating the rocket’s versatility. Estonia’s first satellite, the ESTCube‑1 technology demonstrator, was also released into orbit.
Vega lifted off at 02:06 GMT on 7 May 2013 (23:06 local time 6 May; 04:06 CEST 7 May) on a complex mission requiring five upper-stage boost.

The three crew members will launch May 29, Kazakh time, in their Soyuz TMA-09M spacecraft from the Baikonur Cosmodrome in Kazakhstan for a 5 ½ month mission on the international outpost.
