Radio source SHGb02+14a is another space enigma!
It’s a creepy signal from the unknown and has an overly complicated name that most people can barely say off the top of their heads, let alone remember.
Though its potential for being an extraterrestrial signal was highly exaggerated by the New Scientist, in 2004 radio source SHGB02+14a was found to be the only persistent signal from the best 200 candidates recorded by the Arecibo radio telescope and detected by the SETI@home project at the time.
The signal was detected between Pisces and Aries constellations, without any nearby stars in that vicinity. It’s frequency is around 1420 megahertz – a principal frequency that hydrogen readily absorbs and emits energy. Some scientists have theorized that it’s a frequency that aliens may use.
Though it’s been dismissed by SETI as a potential extraterrestrial transmission, its origins remain unidentified…
