By tying together the observational power of three radio telescopes, astronomers have made the sharpest observation of a distant galaxy, some two million times sharper than human vision. That’s big news in an of itself, but it’s even bigger news for astronomers pursuing next-level Very Long Baseline Interferometry (VLBI). The observation demonstrates a kind of telescopic collaboration that’s never been seen before, hinting at the future of astronomical observation.
