This resolution means that researchers can image and pick out the features of a supermassive black hole such as Sgr A*. It has allowed astronomers to obtain an extraordinary image resolution of several tens of micro-arcseconds, which has been likened to the ability to spot an orange on the surface of the Moon. They did this using the technique of “very long baseline interferometry”, or VLBI, which effectively creates a single, vast array. This endeavour has required an unprecedented level of international collaboration and co-ordination but I’m delighted we’ve finally obtained an image of our own supermassive black hole Ziri Younsi Other studies, including recent observations with the Hubble Space Telescope, had also detected features in the centre of our galaxy and beyond that were assumed to be the hallmarks of an immense, hidden, black hole.īut to take the image of Sgr A*, astronomers have had to combine the capabilities of several radio telescopes – including telescopes belonging to the European Southern Observatory in Chile, as well as observatories in Europe, the US and even at the South Pole.
