Astronomers have captured the deepest and clearest image of the center of the Milky Way galaxy, giving scientists the opportunity to estimate the mass of the giant black hole at the center of the galaxy and its distance from Earth with unprecedented accuracy. Live Science. They were able to observe the motions of the stars around the black hole and measure the astronomical speed at which they traveled near the invisible celestial sphere.
Observations using the telescope of the Southern European Observatory in Chile have uncovered a hitherto unknown star orbiting the mysterious black hole in the center of our galaxy, Sagittarius A *.
The Chilean Observatory Telescope is one of the most advanced in the world. An observer consisting of four main telescopes with a diameter of 8.2 meters and four auxiliary telescopes with a diameter of 1.8 meters can detect stars that emit four billion times less light than we can see with the naked eye.
A technology called interferometry allows researchers to combine the light captured by four telescopes into a single image.https://www.digi24.ro/stiri/sci-tech/descoperiri/astronomii-au-obtinut-cele-mai-bune-imagini-din-centrul-galaxiei-unde-se-afla-o-gaura-neagra- gigantica-cat-de-mare-este-sagittarius-a-1774157
