Well, it's not exactly a "picture" like a photograph is, in the traditional sense.
Most of the very high powered 'telescopes', such as Atacama Large Millimeter/submillimeter Array (ALMA), will use other frequencies to capture the differing emmisions from objects such as the ones displayed above.
As the name suggests, ALMA can "see" light in the millimeter and submillimeter spectrums - that's about 1,000 times longer than that which we can see with our naked eyes.
Longer waves can travel longer distances with less noise or loss (think of the bass and treble in a passing car's stereo).
This particular image is the result of 12 of the 66 radio antennas at ALMA, working together, utilising various spectrums, to express what they discern by providing us with (some rather stunning) visual interpretations
The colours have been retouched to provide for a more dramatic image. You can quite easily see the stars, nebulae and gasses that will form new stars (or, rather, are forming new stars - what we are seeing is around 45,000,000 years in the past...)
When all of ALMA's radio antennas are completed and linked, they will act as one single giant telescope with a lens diameter of 6 kilometres!
Therefore, the more antennas used, the better the imaging.
Furthermore, the largest single telescope on Earth atm is the Large Binocular Telescope in Obs, Arizona, with an effective aperture diameter of 12 metres.
Us Brits got fed up of being outshone by you yanks, so we decided to up the ante
(actually, some of the guys at Manchester and a few from Cambridge are Americans)
