Astronomers have discovered that a black hole about 8,000 light years from Earth It had a peculiar feature that makes it very different from the others: ejects plasma "jets" that move quickly from one place to another.

The researchers published their work this week in the journal Nature, where they claim that the black hole, called "V404 Cygni" behaves "in a way we have never seen in such a short time".

The researchers, led by Professor James Miller-Jones of Curtin University who works at the International Center for Radio Astronomy Research (ICRAR), located in Australia, they pointed out that these black holes are one of the most extreme (behavioral) objects in the universe ".

"It's one of the black hole systems more complex and extraordinary than we have ever seen, "said Miller-Jones. "Like many black holes, it feeds on a nearby star, pushing gas away from the star and forming a disk of material that surrounds the black hole," he explained.

But the difference of the "V404 Cygni" is that the scientists believe that the material disc and the black hole were misaligned. "This seems to be causing the disc inside sways like a top and the jets shoot in different directions, how they change orientation, "they said.

The black hole "V404 Cygni" It was discovered in 1989 when it launched a large radiation explosion that allowed researchers to identify it as such..

Professor Miller-Jones explained that in 2015, "V404 Cygni" had another great "very bright" explosion, which lasted about two weeks. Scientists from around the world used the telescopes they had available to study what was happening.

"Everyone started working with the telescopes we had and we had this incredible observational coverage of the event," he said. It was then that his team discovered that the black hole was behaving very differently for what they had seen so far in other similar systems.

For the main investigation, the team used the largest radiotelematic observation equipment in the United States, conformed by 10 large ones before being located of the Virgin Islands to Hawaii.
