The Arecibo Radio Observatory in Puerto Rico is dead

After a few weeks since the iron wires were faulty and not reparable anymore, today the radio telescope receiver collapsed [1] on to the mirror mounted in the natural crater.

This is a great loss for the radio astronomy guild and also for the science in general, since this oberveratory provided significant informations about the structure of our solar system, the Milky Way, and our universe in total [2]. Not to forget about the search for intelligent life in our galactic vacinity [3].

And more: The telescope was not only important for receiving signals but also for sending, given it's incredible gain of 60 to 90 dB and also used by amateur radio to a great extend [4].

RIP Arecibo. The work will go on!
