Why? I am not a cosmologist and the images I see here and there are quite similar. Plus a physicist tells me that it is a new image of a star so why should I doubt? "Quite obviously" depends on your knowledge of the topic. Scientists are there to help us decide what is true and what is not - and not erode the limited trust we have in science already. If this was a picture of a pokemon - sure. But this round thing with red and white spots togather with a reasonable explanation was not funny at all.
