hardworking pulsar astronomers Jan2011 AO

IMPORTANT: listen to this with good headphones or speakers with good bass reproduction. The best part is to hear the pulsar coming booming in over the sub-woofers.

This video was shot in the Arecibo Observatory control room on the morning of 2011 Jan 27. We were observing the strong pulsar, B0950+08, which is about 850 light years from Earth. So, the sounds you hear on this left the pulsar about 850 years before we are recording them! Since the Arecibo Observatory is the world's largest radiotelescope, you are hearing very powerful pulses. The signal is a radio signal (of random noise), but we convert that into an audio signal and send it to the sub-woofers for the fun of it. Our research at Oberlin College involves studying these pulses -- and data like this -- to understand how the gas in interstellar space affects their arrival at Earth. By correcting for the millionth of a second and below time delay we can use pulsar timing to search for gravitational waves. Read more about this at http://nanograv.org/.

The neutron star- lighthouse theory no longer can explain all the pulse drifting, pulse nulling, pulse quantization, pulse phase memory, and mode switching and memory (grammar) observed in pulsars like PSR 0031-07 , PSR 1237 +25 , PSR 0329 +54 , PSR 1133 +16, PSR 1822 -09 , etc

In other words the ET communication network theory is back & will be told to the public when SETI pretends to change focus from the shortband song of hydrogen to complicated broadband synchrotron messaging.

Amazing....never heard a pulsar before!

I hope the camera was appropriately shielded for RFI
