Is it just me, or does anyone else not see a star in this picture? All I see is a black hole with a disc around it.

Where's the star?

The image has been manipulated to accent the circumstellar disc, so they may have removed the star for that reason. Looks cool regardless.

According to the info, the disc shows up best in the far-infrared, so this is probably the wavelengths used to take the picture. The star may not be very bright in those wavelengths.
The info also says that the disc is 300 AU across, so that is a very 'zoomed-out' picture. (Neptune is only about 30AU from the Sun). At that resolution, the central star may be too small to register as a pixel in the middle, especially after it has been thumbnailed and printed.

I think it's common to mask out the star, otherwise it would overwhelm the sensor and you wouldn't see anything else.

Black is still black, but red might not be red.
