Here is the SLAC news article [1] and the zoomable picture of the romanesco [2]. The picture itself is quite underwhelming - certainly an artifact of how it was created using a pinhole but your phone can capture a better picture of a romanesco.

Besides that, where do the different kind of artifacts - interference fringes, dark and bright vertical lines, white specks - come from? Why are the interference fringes distributed pretty randomly? Dust on the sensor despite everyone wearing bunny suits?
