Supermassive black holes are elusive creatures. Massive gravitational beasts that can power immensely bright quasars, or can lurk quietly among the bright stars of a galactic core. We mostly study them indirectly through their bright accretion disks or powerful jets of plasma they create, but we have been able to observe them more directly, such as our images of M87* and Sag A*.
The photon ring of M87* is captured in the EHT images of the black hole we currently have, but it’s not distinct. Some research has argued that we can pull out the photon ring data from the background, but this has been disputed. A major problem with capturing the photon ring is that the current is at its limit of resolution. It tookjust to get the blurry images of M87* and Sag A* we have.
This study is a proof of concept. It will be decades before we can build such a telescope, and there are several engineering challenges that would need to be solved to achieve such a design. But these ideas are worth thinking about. The photon ring is a holy grail of black hole astronomy, and we will only capture it if we strive to reach further than we have so far.

Correa leads Twins in ALDS against his former team the Houston AstrosHouston manager Dusty Baker admitted this week that Carlos Correa is one of his favorite players. That goodwill toward the former Astro-turned Minnesota star won’t extend into this weekend when Houston hosts the Twins in the AL Division Series. The Twins beat the Blue Jays in the Wild Card Series to win a playoff series for the first time in 21 years and get the chance to face the defending champion Astros, who are in their seventh-consecutive division series.
