The angular separation would be only 0.00013 arcseconds, so very impressive indeed. Hubble has an angular resolution of around 0.05 arcseconds in comparison. Radio telescopes can get better angular resolution than that using interferometry between distantly separated telescopes. Perhaps that's how they can do it.
- Keysh 5y agoThe reported angular resolution (in the main paper: https://arxiv.org/abs/2201.10541 https://arxiv.org/abs/2201.10541) is 4 arcseconds. This is radio interferometry, which makes for better resolution, but it’s at a very low frequency (centered around 1.28 GHz = about 23 cm), which makes for worse resolution.
