SETI has discovered an interesting signal out in space. The signal has been detected 3 seperate times all together. In the last instance, the signal actually became stronger. Interestingly, the signal comes from a point in space with no visible Stars within 1000 Light Years of the signal. They are not declaring this to be Alien Life, but it is an interesting repeatable phenomenom.

Named SHGb02+14a, the signal has a frequency of about 1420 megahertz. This happens to be one of the main frequencies at which hydrogen, the most common element in the universe, readily absorbs and emits energy.

Some astronomers have argued that extraterrestrials trying to advertise their presence would be likely to transmit at this frequency, and SETI researchers conventionally scan this part of the radio spectrum.
