Black holes have always attracted researchers. Such space objects possess a huge gravitational force and attract absolutely everything that gets in their ranges, even the light. Thanks to the new technologies, scientists were able to study them and draw some important conclusions. A new study reveals that massive black holes are larger than we thought and are more common in the Universe.

The largest black hole ever discovered has a mass of 40 billion times larger than that of the Sun and has been named S5 0014+813.

Another huge black hole has been recently discovered at the center of a distant galaxy an has a mass of 17 billion times large than the Sun. This latest discovered huge black hole, scientifically named NGC 1277, is 220 million light-years away from Terra, in a galaxy that’s 10 times smaller than the Milky Way.

Black holes, by size

Scientists have split black holes into three categories depending on their size. Therefore, there are:

  • Stellar black holes – 5-30 times bigger than the Sun;
  • Intermediate black holes – 100-10,000 times more massive than the Sun;
  • Ultramassive black holes – several million or billions of times larger than the Sun;

However, some astronomers believe that is necessary the addition of a new category that differentiates the black holes of millions of times larger than the Sun of those of billions of times bigger.

Chandra offers great data to researchers

Chandra is a huge X-Ray telescope owned by NASA.

Astronomers from Spain and Canada studied more than 70 readings made by Chandra telescope about galaxies up to 3.5 billion light-years away.

The study revealed that Chandra X-Ray can offer a more accurate measurement of the far-away ultramassive black holes. They concluded that, in reality, massive black holes are now 40% bigger than previously thought.

The ultramassive black holes are increasing as we speak and they do it at a faster pace than their host galaxies.
