UPDATE: It is online in the Mediathek.
Apparently, the documentary for which a German television team visited the institute last week will be aired tomorrow it now seems to be scheduled for Friday 23rd evening on “3Sat” in a “Nano” show at 6:30 pm. Unfortunetely it is in German, of course, but it will be available online after the show. I will post a link once it is online.

At ESA you can find a very cool sound file: the radio emission that takes place during the aurora (polar lights) is converted into a signal you can listen to.
The graph that accompanies it gives amplitude versus frequency, but unfortunately the exact frequencies are nowhere given. I would have liked to get some more information on how they converted the radio signal to sound. It is a common misunderstanding to think radio astronomers are listening the universe. They are not, they are only receiving similar frequencies (or wave length) like earth bound radio stations. It is a pity that the ESA text states in the first part that “In reality, they are the sounds that accompany the aurora”. There simply are no sounds in space because sound waves need some medium, like air, to travel in. But still, the sound they made out of the aurora signal is amazing.
And as I have written about the European astronaut application deadline previously, I think it is fair to mention the one by NASA, for it’s New NASA Astronaut Class. As I understand it, you will either need a degree and experience in math, science or engineering, and/or experience as a jet pilot. They are also looking for people with educational skills, so if you have experience in teaching this seems to be a bonus.
The deadline is July 1, there is more information and a link for the online application in the NASA press release.
