| Planetary missions probe giant eruptions in the Sun's corona |
| Scientists have probed the corona of the Sun by studying the disturbances that it causes to radio transmission from three of ESA's planetary missions: Mars Express, Venus Express and Rosetta. The measurements were performed on several occasions, when each of the spacecraft was located behind the Sun as viewed from Earth. In particular, five coronal mass ejections were detected with Mars Express in 2004. Analysis of these data has revealed the morphology of these colossal solar eruptions in great detail, complementing the view that can be achieved via direct imaging of the Sun's corona. |

| Hubble unmasks ghost galaxies [heic1211] |
| Astronomers have used the NASA/ESA Hubble Space Telescope to study some of the smallest and faintest galaxies in our cosmic neighbourhood. These galaxies are fossils of the early Universe: they have barely changed for 13 billion years. The discovery could help explain the so-called "missing satellite" problem, where only a handful of satellite galaxies have been found around the Milky Way, against the thousands that are predicted by theories. |

| X-raying the beating heart of a newborn star |
| An international team of scientists has used the world's most powerful X-ray observatories - including ESA's XMM-Newton orbiter - to probe the dusty surroundings of a newborn star and discover some of its innermost secrets. These findings shed new light on one of the most fundamental processes in the Universe, the creation of stars. |
