The black hole that shouldn’t be like that

The Hubble Telescope has located around a supermassive black hole a disk of materials that revolves around it and should not exist.

The more we dive in the universe the more we realize how little we know. Occasionally there is some event or discovery that reminds us vividly. It is what has happened after the observation, by means of the Hubble Space Telescope, of an unknown astronomical phenomenon.

It is located in the center of the galaxy NGC 3147, which is 129 million light years from Earth. There is a supermassive black hole surrounded by a material accretion disk (gas and dust), which spins at high speed and is extremely thin. This is an anomaly, since scientists understood that only the so-called tremendously ‘active’ galaxies have such accretion discs.

NGC 3147 is not a particularly ‘active’ galaxy, so the discovery of Hubble disputes the assumptions of scientists. Hubble has collected data on the supermassive black hole, which has a mass 250 million higher than that of our sun. In addition, it rotates at 10% of the speed of light.

The discovery implies that current models on low-light galaxies have failed. And it is that the scientists had selected this galaxy to confirm their models on galaxies of low luminosity. Instead of a confirmation they have found the opposite.
The scientists thought that below certain luminosities – in this range was the galaxy NGC 3147 – there was no accretion disk. Thus, from now on the models of galaxies and black holes could be modified, in order to understand them better.

In addition, scientists point out that this phenomenon also offers an opportunity to study theories of relativity and its application. The disk is within the gravitational field of the black hole and would allow researchers to study how light is affected.
