Scientists capture the deepest and most accurate picture of the Milky Way’s supermassive black hole

Astronomers have revealed the deepest and most accurate images yet of the region surrounding a supermassive black hole Our Milky Way GalaxyThe stunning new images, taken at different times earlier this year and published today by the European Southern Observatory (ESO), show several stars moving around an orbit. Black hole Arch A*.

According to the British newspaper, “Daily Mail”, ESO researchers used the Very Large Telescope (VLT), located in the Atacama Desert in northern Chile, to capture the images, which are magnified 20 times more than was possible before.

The research team, known as the GRAVITY Collaboration, developed a new technique to obtain the deepest and most accurate images to date of the galactic center in our Milky Way, and used the Very Large Telescope (VLT), a facility operated by ESO at the Paranal Observatory in the Atacama Desert in northern Chile.


Scientists also revealed an unprecedented star near the black hole, called S300, which provides the most accurate estimate of the mass of the Milky Way’s central black hole to date, which is 4.3 million times the mass of the Sun.

The achievement was also detailed in two papers published today in Astronomy & Astrophysics, by an international team of experts who wanted to learn more about Sagittarius A* in the constellation Sagittarius.

Black holes are regions in spacetime where gravity pulls so much that light can’t get out. They act as intense gravitational sources that lift the surrounding dust and gas.

Perhaps the stars in our galaxy, including our sun, revolve around Sagittarius A* because of the force of their gravity, and these stars revolve around the black hole that is trillions of miles away, because they will be swallowed up if they get too close, and the Earth is about 27,000 light years away, or more than 150 trillion miles about the black hole.
