Microwaves

Scientists at an Australian radio telescope has searched in vain for seventeen years to find the source of strange signals. They found out this year what the source was. It was nothing more strange than microwaves from the microwave oven in the kitchen of the observatory. When the door of the oven was opened before the programme was over, microwaves left the oven and was detected by the radio telescope.

They must feel a little silly, realizing this was the source of the signals. The staff caused the signals themselves, without realizing it.

They would not even have had the help of a dog sniffing out the solution, because microwaves cannot even be detected by the sharp noses of dogs. I wish we could, but there are limits even to our sniffing abilities.

Oh well, I guess science has made some progress by this discovery as well.
