Radio source SHGb02+14a

Radio source SHGb02+14a is a source and a candidate in the Search for Extra-Terrestrial Intelligence (SETI), discovered in March 2003 by SETI@home and announced in New Scientist on September 1, 2004.

The source was observed three times at a frequency of about 1420 MHz, one of the frequencies in the waterhole region, which is theorized to be a good candidate for frequencies used by extraterrestrial intelligence to broadcast contact signals.

There are a number of puzzling features of this candidate, which have led to a large amount of skepticism. The source is located between the constellations Pisces and Aries, a direction in which no stars are observed within 1000 light yearsof earth.It is also a very weak signal. The frequency of the signal has a rapid drift, which would correspond to it being emitted from a planet orbiting nearly 40 times faster than the Earth around the sun. Each time the signal was detected, it was again at about 1420 MHz, the original frequency before any drift. The signal may represent a resonating pulsar across a Gaussian belt

There are also a number of potential explanations for this signal. SETI@home has denied media reports of a likely extraterrestrial intelligence signal.It could be an artifact of random chance, cosmic noise or even just a glitch in the technology.
