SETI has adopted these assumptions in their search, looking for such "infrared heavy" spectra from solar analogs. As of 2005 Fermilab has an ongoing survey for such spectra by analyzing data from the Infrared Astronomical Satellite (IRAS). Identifying one of the many infra-red sources as a Dyson Sphere would require improved techniques for discriminating between a Dyson Sphere and natural sources. Fermilab discovered 17 potential "ambiguous" candidates of which four have been named "amusing but still questionable". Other searches also resulted in several candidates, which are however unconfirmed.

The problems with finding ET communications signals is a complex one.
SETI has assumed that ET, assuming they desire to advertise their presence or like Humanity on Earth, have been careless about their radio emissions and allow them to radiate into space for anyone who might be listening to pick up, will be broadcasting using radio.
This is a ridiculous assumption.
We assume ET is technologicaly advanced, so my guess would be that they would no longer be using something as primitive as radio, and would more than likely be using a communications system based in Quantum science.
Probably far ahead of our own currently early poking and prodding into the area of the Quantum sciences.
Perhaps ET's signals are....all around us, everywhere we look in space. The problem is, if they are using a form of Quantum entanglement having got around the decoherence problems we're currently scratching our heads about, the moment we try to 'read' or otherwise detect one of their Quantum signals...it degrades into random noise due to decoherence.
Maybe the random static or noise we see and hear on an untuned TV or radio set...is actually the remains of ET's Quantum communications, broken down into nothing coherent becuase we observed it or tried to record/listen to it.
As we make progress in the Quantum field...we'll probably discover the chatter surrounding our local area of the Galaxy is everywhere.

There are many credible reports of UFO sightings . Even there is a rumor that Aliens are living amongst us , such as MIB
So , why don't we simply ask them where did they come from instead of spending billions of $$ in the name of Alien hunt ?
