There is a place at the centre of our Galaxy where the rules of physics are pushed to their limits. Squeezed into a region smaller than our Solar System sits Sagittarius A*, a supermassive black hole four million times the mass of our Sun. The space around it is a churning and chaotic environment where stars orbit at breakneck speeds, gas swirls through intense gravitational fields, and anything straying too close risks being torn apart and consumed. Yet for all its violence, one of the biggest mysteries here has been surprisingly simple; what on earth (pardon the pun) is feeding it?

Known as G1, G2, and G2t, these compact clumps of ionised gas each carry roughly the mass of a few Earths.…
