Important Question: Why this orange blob AGAIN?
The Event Horizon Telescope (EHT) captured two historically significant images of supermassive black holes:
M87* in 2019 and Sagittarius A* (Sgr A*) in 2022.

Following the historic 2019 celebration of the Event Horizon Telescope’s (EHT) first black hole image, M87*, my team and I anticipated a crucial public question: ‘Why, three years later, was a significant investment made to capture another similar ‘orange blob’ of Sagittarius A*?’ We recognized that complex technical details could overshadow the profound narrative.
I took the lead in guiding our scientists to directly address this curiosity. My vision for the animation was to illuminate the unique significance of the Sgr A* image by focusing on three key aspects:
- Our Galactic Heart: Visualizing Sagittarius A*, the supermassive black hole nestled at the very center of our own Milky Way galaxy.
- Comparative Insights: Explaining and illustrating the major differences between these two colossal black holes, revealing why both images were essential for a comprehensive understanding.
- A Planet-Sized Eye: Demystifying the incredible engineering behind the EHT – how powerful observatories spanning the globe connected to form a virtual telescope the size of Earth itself.
This animation successfully bridged the gap between intricate scientific details and public understanding. It was instrumental in helping policymakers and the public grasp the importance of funding such groundbreaking research, ultimately making complex astrophysics relatable and showcasing the unparalleled significance of the Sgr A* image.
