The Event Horizon Telescope, a global network of radio dishes including ALMA, produced the first image of a black hole's shadow — the supermassive black hole at the heart of the galaxy M87.

A smooth, featureless ellipsoid of mostly old stars, with little gas and little ongoing star formation. The largest ellipticals sit at the centres of galaxy clusters and are thought to be built by mergers.
The nearest large galaxy cluster, over a thousand galaxies bound together and centred on the giant elliptical M87. Its gravity draws the Local Group toward it, and it anchors our corner of the local supercluster.
