Astronomers were able to get the first images of Sagittarius A. This was made possible by Event Horizon Telescope. This project was worked on by an international team. Sagittarius A is about 26,000 light years from the Solar System. Sagittarius A is a supermassive black hole located at the Galactic Center of the Milky Way Galaxy. These images are revealing more information about the most bizarre objects in space. The Event Horizon Telescope collaboration involved a global network of telescopes. The technique used to obtain the image is known as very long baseline array interferometry. A combination of radio antennas was used to gain information from space. Atomic clocks and supercomputers were used to produce this image. The biggest problem getting an image is that a black hole bends light. There are accretion disks, which account for a shape being seen in darkness. What is incredible is that plasma travels around Sagittarius A at high speeds. Plasma is a super heated gas. Stars are also close to this black hole. The gravitational force is controlling star movement. Some astronomers have suggested that dark matter could also be next to Sagittarius A. With more images and observations about black holes being produced, it confirms the the theory of relativity. Theoretical physics and mathematics were able to provide early descriptions of black holes. More is to be learned about Sagittarius A. Overtime technology will enable humankind to explore unknown objects of the universe.
