The Atacama Large Millimetre/submillimetre Array has produced a spectacularly detailed image of a distant galaxy known as SDP.81 that is being gravitationally lensed. The image shows a magnified view of the galaxy’s star-forming regions, the likes of which have never been seen before at this level of detail in a galaxy so remote.
