The Galactic center is the point at which our Galaxy is rotating. It is located roughly 24,000 light-years from the Solar System in the direction of the constellation Sagittarius but cannot be seen in optical light due to heavy obscuration by interstellar dust grains along the line of sight.

The Sun is 25,000–28,000 ly (7.7–8.6 kpc) from the Galactic Center. The Galactic Center is marked by an intense radio source named Sagittarius. The motion of material around the center indicates that Sagittarius A* harbors a supermassive black hole with an estimated mass of 4.1–4.5 million times the mass of the Sun. This SMBH was recently imaged by the Event Horizon Telescope.

Our SAASST 5-m radio telescope observed the galactic plane at 1.4 GHz with a resolution of 2.4 degrees. The false-color image below was obtained using an integration step time of 15 seconds for each pixel. This combines to a total of 30 minutes of observation. This image was taken on May 15, 2022, starting from 03:08:12 am Local Time. The total frame size is 26.62 degrees per 26.62 degrees. Unfortunately, the low elevation of the Milky Way center made it difficult to take the image. It reached a maximum of around 35 degrees. Since the map was ± 13 degrees from the center, it was getting close to the minimum elevation limit for the telescopes, which is 15 degrees. The whitish band on the image represents the galactic plane.
