Astronomical Seal Observatory Images M13
The Astronomy Observatory affiliated with the International Astronomy Center successfully captured a high-resolution image of the globular star cluster "Great Cluster" (M13), located approximately 24,000 light-years from Earth in the Hercules constellation. Its estimated star count ranges between 300,000 and half a million stars, and it spans about 145 light-years in diameter. It is considered one of the oldest components of the Milky Way galaxy, with an age exceeding 11 billion years. The image reveals a dense concentration of stars at its core, featuring red giant stars and scattered blue stars. Capturing this image required about 11 hours of exposure using a 4.3-inch telescope.
