Ceres

Dawn orbiter nears the finishing line

2. March 2015

It is only a few more days until the Dawn spacecraft enters orbit around Ceres on 6 March 2015, marking humankind's first visit to a dwarf planet. What Ceres has disclosed to scientists so far has raised more questions than it has provided answers.

High-pressure air fights aircraft noise – compressed air substantially reduces engine noise

27. February 2015

The large blades of the fan dominate when looking at an aircraft engine from the front. They are also among the largest producers of in-flight noise. Researchers conducting trials at the German Aerospace Center (DLR) have now succeeded in demonstrating, for the first time anywhere in the world, that fan noise can be reduced substantially by introducing compressed air.

Promising crater-strewn landscape on dwarf planet Ceres

25. February 2015

Only 46,000 kilometres separated the Dawn spacecraft from its destination, the dwarf planet Ceres, when its German-built Framing Camera acquired the latest images on 19 February 2015. One of the most striking features of Ceres is the multitude of different crater shapes across its surface; in addition to numerous smaller, shallow craters, the images also reveal impact basins with large mountains located at their centres.

Metamorphosed by climate change – the southern area of Phlegra Montes

19. February 2015

The mountain massif of Phlegra Montes extends into the northern lowlands of Mars like a long, slightly curved salient. Stretching for hundreds of kilometres, this alignment of numerous mountains, rolling hills and ridges lies to the east of the volcano Hecates Tholus in the Elysium volcanic region.

Comet 67P/Churyumov-Gerasimenko 'shedding its skin' in the heat of the south

9. February 2015

Comet 67P/Churyumov-Gerasimenko could lose up to 20 metres of surface material from its previously unilluminated south side when it heats up, starting in May 2015. The increasing heat as the comet approaches the Sun will trigger this 'diet', during which gases and solid materials will be ejected into space.

Dwarf planet Ceres in the spotlight

27. January 2015

Planetary scientists have never seen dwarf planet Ceres from this close up. The German-developed Framing Camera on board NASA's Dawn spacecraft acquired this image on 25 January 2015 from a distance of just 237,000 kilometres.

Comet Churyumov-Gerasimenko – pitch black and full of contrasts

26. January 2015

It is still early days for the scientists involved in evaluating data that the 21 instruments on board the Rosetta spacecraft and its Philae lander have transmitted back to Earth. But preliminary results from seven of the 11 instruments on the Rosetta orbiter have been published in a special edition of the journal Science.

Mineralogical diversity in Nili Fossae on Mars

22. January 2015

Nili Fossae caught the attention of astronomers in the last century, when Mars could only be observed from Earth with ground-based telescopes. The grabens of Nili Fossae extend for several hundred kilometres along the eastern edge of the giant impact basin Isidis Planitia and, together with the volcanic region Syrtis Major, they form a concentric pattern that runs parallel to the edge of the basin.

Dawn – heading for icy Ceres

19. January 2015

Planetary scientists at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) may find a thick ice crust with an ocean underneath when the NASA Dawn spacecraft arrives at Ceres in March 2015. Even now, from a distance of 383,000 kilometres, the first surface features are visible.

New telescopes to search for planets outside the Solar System

14. January 2015

The Next-Generation Transit Survey (NGTS) telescope at the Paranal Observatory, operated by the European Southern Observatory (ESO) in the Atacama Desert in northern Chile, has achieved 'first light'.
