RADIO SKY SOURCES

Up to now, thousands of radio sources have been discovered in the sky. Some of them correspond to extremely far away objects on the very edge of the universe. For the size of antennas HAM's are using with EME communication, some very distant objects can also be detected.

With only a couple of days a month for EME activity your antenna set-up could also be used for radio astronomy experiments.

                                                                     Our recent results with 25m Dish of PI9CAM

Below you will find a table which shows the results of HAM's observing these weak radio sources.

Please feel free to inform me on your results!
