Chasing Pluto's shadow

Pluto-Okkultation

Astronomers on board SOFIA fly over most of the water vapour in the atmosphere; it is precisely this that makes the desired infrared observations possible. But the fact that SOFIA flies has another major advantage: it is a mobile observatory. In contrast to ground-based observatories, it can be used at different locations around the globe. This can be very useful, for example, for the Pluto occultation that will take place these days. read more

Is the Moon unchanging?

Mond TLP

Ever since the discovery of the telescope, man has been fascinated by the observation of the surface of the Moon. The constantly changing light coming from the Sun causes craters, mountains, valleys and plains to take on continuously varying appearances. Yet, as we look at this atmosphereless natural satellite, we get the impression that the Moon has not changed, even over the span of a human lifetime. But is this really the case? read more

The final stage in the construction of the German-Indonesian tsunami early warning system

On 26 December 2004, a devastating tsunami destroyed large parts of the coastline of the Indian Ocean. It is estimated that 250,000 people lost their lives because there was no early warning system. Shortly afterwards, the German government decided to spend 50 million Euros to develop a tsunami early warning system in Indonesia, the most severely affected country. Scientists from major German research centres presented innovative concepts for such a system to the political decision makers. Convinced of the feasibility of the proposal, the German Federal Ministry of Education and Research (Bundesministerium für Bildung und Forschung; BMBF) decided to support the project, now named the German-Indonesian Tsunami Early Warning System (GITEWS), as a joint development led by the German Research Centre for Geosciences (Deutsches GeoForschungsZentrum; GFZ) in Potsdam. read more

Biggest full Moon in over 18 years

On 19 March 2011 everything came together perfectly – in a completely clear sky there was a full Moon and, what is more, at almost the exact time, the Moon passed through the point of closest approach to Earth on its elliptical orbit. This meant we were able to admire an unusually large and bright full Moon. Not wanting to let this opportunity pass, I photographed the Moon through my telescope. read more

Captured from ground: ATV Johannes Kepler and Space Shuttle Discovery docked with the ISS

On Tuesday, 1 March 2011, Dirk Ewers, one of our readers, caught the International Space Station (ISS) on camera, as it was passing overhead in the evening sky near Kassel in central Germany. Ewers has sent in the fantastic images that show ATV-2 Johannes Kepler and Space Shuttle Discovery docked with the ISS. Using almost 2000 of these individual images, he has put together a video sequence of the docked spacecraft passing almost directly overhead. read more

'The Future of Energy' Year of Science: A different question every week, 1 answer and 150 comments

During 'The Future of Energy' Year of Science, DLR prepared one question each week on the topic of energy, answered by the science journalist, Jan Oliver Löfken. Users were invited to post their questions and comments on the blog, and we responded as they came in – we received a total of 150 contributions. Read 51 posts on our Energy Blog and see how researchers want to safeguard our energy supply in the future and what policies are being put in place for this in the world of politics. read more

Spotted: strange object flying over SOFIA

Earlier this week I received a slightly puzzling email from my colleague Alan Brown over at NASA's Dryden Flight Research Center. He reported that earlier this month, on the night before SOFIA was due to start her first scientific flight, a strange cargo aircraft with a very odd propulsion system was spotted flying overhead. At that time, SOFIA's telescope system was still being tested for the flight next morning. Tom Tschida took a couple of quick shots, but when he looked back a moment later, it was gone! read more

DLR's presence on blogs and Twitter during the volcanic eruption in April 2010

Eyjafjalla

As the Eyjafjallajökull volcano erupted, in Iceland at the end of March/ early April 2010, its ash cloud created an unprecedented situation for European air travel. By mid-April, air travel over northern and central Europe was resumed. DLR was involved in investigating the ash cloud and its effects on air travel in several different ways. I'd like to use this blog entry to illustrate our experiences and learning processes in online communication over this period in mid April 2010, especially on DLR blogs and on Twitter. read more

Walking on the Moon – by telescope

We have all seen the images of the first manned Moon landing in 1969 often enough on the TV and remember the pictures of the lunar surface taken from orbit or from the landing site itself. But how much of all this can be seen with a telescope? And just where is the landing site? Here is a travel guide with a very special destination. read more
