Impressed by the first image of black hole? Wait till scientists capture a video. Details here
After the astronomers took pictures of supermasif black holes for the first time in history, they are now looking to record videos that will show churning and the movement of the horizon of the event and gas that orbits around the surface.
The black hole image, which was appointed by Sagittarius A* (Sgr A* in short), was released by astronomers who observed black holes using the Telescope Horizon Event (EHT), the main observation collaboration worldwide.Only about 27,000 light years from Earth, black holes are found about four million times the mass of the sun.
Because SGR A is 2,000 times closer to earth than a black hole in M87, this is a strong target for research black holes. However, SGR A is 1,500 times more compact than the M87 black hole, which means that attracting SGR A is much more difficult because the gas flow moves faster and changes quickly.
EHT used for this study is a super ultra-telescope virtual coordinated by eight radio observatorys worldwide. Now, to capture video objects, engineers are working on repairs in EHT which is likely to be completed in 2024.After the repair is complete, EHT will observe the black hole for several years before turning it into a video.
According to Space.com, Michael Johnson, an astrophysics at the Harvard -Smithsonian astrophysics center, said that the next step was to capture polarized images from SGR A* to observe the magnetic field line that was dragged into it. Scientists also plan to add more radio telescopes to networks in the coming years to increase resolution, allowing scientists to see smaller details.
The researchers also tried to make the M87* film in 2017 using data from observations. They have developed algorithms to make films. However, data is not enough for clear visualization.
