Millions Of Hidden Black Holes Discovered In Our Milky Way Galaxy

A team of researchers has managed to discover twelve black holes grouped around Sagittarius A, the supermassive black hole which resides at the heart of the Milky Way Galaxy. The discovery has confirmed a decade-old theory, which could allow researchers to find more black holes in the future.

Researchers from the University of California aimed to calculate the number of black holes in the galaxy, but the results suggest that there may be millions of black holes within the Milky Way, much more than it was expected at first.

A team of Japanese astronomers led by Shunya Takekawa observed an odd interstellar gas cloud which was moving through the Sagittarius constellation. The cloud captured the interest of the researchers, and they employed the Atacama Large Millimeter/submillimeter Array (or ALMA) to study the features of the cloud in detail.

There Are Millions Of Hidden Black Holes In The Milky Way, Our Home Galaxy

The results were quite surprising as the team discovered hidden black holes which influenced the gas cloud which swirled around the object. At first, the researchers believed that an invisible object attracted the cloud, but its real nature was revealed. A hidden black hole is an intermediate-mass object, and it is now understood that over 100 million of these black holes exist in the Milky Way Galaxy. The new method used to reveal the black holes could also be employed in the future to find similar black holes and learn more about the mechanics which lead to their formation and development.

It is generally thought that small black holes will appear and grow into bigger or even supermassive black holes as time passes. The mass of most supermassive black holes is equal to hundreds or even thousands of suns.

In-depth research showed that a massive object, which was up to 30,000 times heavier than the mass of the sun, was found in an area which is considerably smaller in comparison to our solar system. The results were published in a peer-reviewed study.
