-Following the success with M87*, astronomers aimed to image the supermassive black hole at the center of our galaxy, Sagittarius A*. Imaging Sagittarius A* posed unique challenges due to its smaller size and the rapid variability in its surrounding environment, which changes much faster than the environment around larger black holes like M87*. This rapid movement made it difficult to capture a stable image that accurately represents the structure around Sagittarius A*. Just like our kitten example! Despite these challenges, the images obtained are significant for testing Einstein's theory of general relativity under extreme gravitational conditions. While these observations are crucial, they are part of a broader array of methods used to test the predictions of general relativity.
