🔤 EHT A-Z
We’re breaking down the science behind the Event Horizon Telescope - one letter at a time.

📡 Y is for Years of Observations

The EHT has observed its targets across multiple years - 2017, 2018, 2021, 2022, 2023, and 2024.

By comparing these observations, we can begin to track how black holes and their environments evolve over time.
