![]() The research has been submitted to The Astrophysical Journal. Our galaxy likely contains its own supermassive black hole near the border of the constellations of Sagittarius and Scorpius. The largest natural BHs we know of the the supermassive BHs in galactic centers. More interesting, perhaps, are the BHs which formed naturally. But there's no way in nature that a Black Hole that big could form. It has been suggested that supermassive black holes are found at the centre of most galaxies, such as our own, the Milky Way galaxy. There's no maximum theoretical size short of the size of the universe. Some astronomers have started using the term "ultramassive" for black holes which have a mass 10 billion or more times larger than our nearest star. The largest black hole measured to date is TON 618, which is 10.37 billion light-years from Earth and is said have a mass 66 billion times bigger than the Sun.Ī supermassive black hole is the largest formal classification for black holes, measuring hundreds to billions of times larger than the Sun. ![]() "The supermassive black hole of Holmberg 15A is not only the most massive one to date, it is also four to nine times larger than expected," said the team. Physicist Kianusch Mehrgan and her colleagues have highlighted the supermassive black hole was also much larger than previous estimates. At the animation’s larger scale lies M87’s black hole, now with a updated mass of 5.4 billion Suns. Light from the supermassive black hole known as TON 618 (circled) takes more than 10 billion years to reach us. The explorer is located at the VLT at the European Southern Observatory in Chile, which is used by 16 countries including Germany and the UK. Astronomers are exploring other detection techniques to tackle even bigger mergers.
