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?

Does anyone else feel like BBC writing has gone into the loo lately? Popular science reporting doesn't need to sound like sixth grade book report filler.

It was made just to test the camera sensor without any lenses, just a pinhole. That means that the photo blurs relative to the size of the pinhole, which probably wasn't that small.

These are just the first full-focal plane images, there's a lot of parts in the system that are set up for testing _the sensors_ and it's geared towards that.

Gah, really?
