Just read about a 'lonely planet' floating without a star - and it's much bigger than Jupiter (which itself is almost big enough to become a small star able to radiate light and heat) - and this 'lonely planet' actually radiates mostly in the infra-red. Well, a long time ago Freeman Dyson said that's one way we could detect stars that had been 'contained' for energy-use purposes, by alien civilizations! ----- ScienceWorld Report http://tinyurl.com/le6haz2 Astronomers have discovered a strange free-floating planet dubbed PSO J318.5-22 that is 80 light years away from the Earth and has a mass that is six times more than Jupiter. The star hosts no stars. It came into existence some 12 million years ago, which is like a newborn in planet lifetime. The astronomers identified the strange lonely planet from its faint and exclusive heat signature as it didn't match the objects surrounding it. It was identified with the help of a survey telescope Pan-STARRS1 (PS1) that is located on Haleakala, Maui. This is not the first time that astronomers have spotted such free floating objects. But it was unclear till date whether these free floating objects were failed stars or orphaned planets. But this finding confirms that they are indeed planets. The light coming from PSO J318.5-22 is nearly 100 billion times fainter in optical wavelengths compared to the planet Venus. Most of the planet's energy is emitted in infrared wavelengths, NBCNews reports. --- http://en.wikipedia.org/wiki/Freeman_Dyson#Dyson_sphere In 1960 Dyson wrote a short paper for the journal Science, entitled "Search for Artificial Stellar Sources of Infrared Radiation". In it, he theorized that a technologically advanced extraterrestrial civilization might completely surround its native star with artificial structures in order to maximize the capture of the star's available energy. Eventually, the civilization would completely enclose the star, intercepting electromagnetic radiation with wavelengths from visible light downwards and radiating waste heat outwards as infrared radiation. Therefore, one method of searching for extraterrestrial civilizations would be to look for large objects radiating in the infrared range of the electromagnetic spectrum. ----- Cheers Ray D Listen to 'Strange Days...
