Was reading the article, excited by the prospect when I realised, we have a hard enough time identifying planets dozens of light years away, from direct light, that surely the reflected light from a massive object 3000 light years away would be orders of magnitudes more difficult. Perhaps impossible. Theoretically possible yes, but what sort of technology needs to be invented to actually do it? edit: turns out I should have just finished reading the article.. bigger telescopes!
