So is there? :) ... Is there anything (radiation waves, particles, what not...) That Sun absorbs more than it emits? I guess it absorbs visible light of stars behind it, but it emits a ton of more. But is that the case with all EM frequencies? What about gamma rays or any other background radiation? How about small particles, like neutrinos? Something that would actually render a black circle in Suns place on image map when detecting?
