Black holes are one of the biggest mysteries of the universe. This mystery attracts physicists and astronomers alike but also passionate astrophysicists. The only evidence of the existence of black holes was achieved last year with the detection of gravitational waves arising from the merger of two large astronomical objects, according to descopera.ro Now, US astronomers are preparing to produce the first image of a black hole located in the center of the Milky Way, Sagittarius A.
The photo to be made next year
The picture will be conducted by mission specialists involved in the Event Horizon Telescope (EHT). Researchers will use the new radio telescopes located in several places around the globe to obtain the performance of a complex virtual telescope.
Algorithm created by a team of researchers
The system will operate using an algorithm created by a team of researchers from MIT (Massachusetts Institute of Technology). The calculation mechanism was called CHIRP (Continuous High-Resolution Image Reconstruction Using Patch priors) and it uses pictures from outer #Space to create a mosaic with observational data that will be used to create the image of a black hole.
One of the reasons that scientists need a complex telescope is the fact that black holes are located at an extremely high distance compared to our planet. Moreover, they have a very similar structure. For example, Saggitarius A has a diameter 17 times larger than the Sun, but it is located at a distance of about 25,000 light-years from Earth.
The researcher Katie Bouman told MIT News that achieving the image of a black hole located in the center of the Milky Way on Earth is the equivalent of photographing a grapefruit from the Moon with a radio telescope. A telescope with a diameter of about 10,000 kilometers would be needed to capture an object so small, which is impossible to build given that our planet has a diameter of less than 13,000 kilometers, according to the researcher .
Experts say the first picture of a black hole will be obtained next year, but they don't know what the exact date of achievement would be. #Science
