The most detailed and sharpest photo ever was Sagittarius A* An area around a black hole called the MTI reported the discovery. Meanwhile, researchers have discovered a hitherto unknown star in the center of the Milky Way, and by analyzing the star’s orbit, they have made high-resolution measurements of the black hole’s mass so far. Astronomy and astrophysics in the scientific journal Published in a study mentioned.
To learn more about the dark center of the Milky Way, such as the black hole’s exact mass, whether it rotates, and whether stars behave in the same way expected from Einstein’s theory of relativity, it’s best to follow the stars. On their path near a supermassive black hole, Genzel told the European Southern Observatory (ESO) in her contacts.
Reinhard Genzel, Director of the Max Planck Institute for Extraterrestrial Physics in Garching, for his research on Arc A* in 2020 Received the Nobel Prize in Physics Shared with researchers Roger Penrose and Andrea Geis.
With the help of ESO’s Very Large Telescope (VLT) and an instrument called Gravity, Genzel and his research team were able to make accurate observations hitherto inaccessible and were able to zoom in twenty times closer to the area than ever before. “We are amazed at the richness of detail, the movement and the number of stars around the black hole,” said Julia Stadler of the Max Planck Institute for Astrophysics.
Thanks to this, the researchers were able for the first time to see the previously unknown star, called S300, which has been hidden from researchers due to its dim light. In their latest observations between March and July, scientists focused on accurate measurements of stars near the black hole. One of these stars is S29, which passed through the black hole at a speed of 8,740 kilometers per second at a distance of only 13 billion kilometers at the end of May. So far, no star has been observed to pass too close or too fast to a black hole.
Based on our observations, we were able to more accurately determine the mass of the black hole and its distance from the solar system.
Gernot Hesel of the Paris Observatory explained the significance of the discovery. Accordingly, Sagittarius A * has a mass of 4.3 million times the mass of the Sun and 27,000 light-years from Earth. Thanks to this discovery, researchers have been able to confirm this with greater accuracy than ever before
The orbits of the stars correspond to Einstein’s theory of relativity.
