The picture is clear, but the blackhole name is unclear


The newly displayed supermassive black hole is a beast without a name, at least not official. And what happens is a cosmic confusion.

A team of astronomers who created the image of a black hole called it M87 (star). (The asterisk is silent.)

The professor of languages ​​gave him a name from the Hawaiian term – Powehija – which means "decorated immaculate dark creation". And an international group responsible for giving astronomical names? She never named black holes.

The black hole concerned is about 53 million light-years away in the center of the galaxy called the Messier 87, or the M87.

On Wednesday, scientists uncovered an image taken with eight radio telescopes, when people first saw one of the dense objects of heaven, embracing everything around them, even the light.

The International Astronomical Union usually takes care of the names, but only for things in our solar system and the stars outside it. There is no committee dealing with other objects, such as black holes, galaxies or nebulae.

The last time that the situation was similar, the former Pluto was somehow degraded to a dwarf planet that led to a public protest, said astronomer from college Williams Jay Pasachoff, a member of the board for the designation of stars.

Technically speaking, our galaxy – the Roman Road – was not officially appointed by the IAU, said Rick Fienberg, astronomer and spokesman for the American Astronomical Society.

He said: "This is just an expression that has come through history."

"Almost every object in the sky has more than one mark," Fienberg said.

"The constellations have official names approved by the IAU, and in other cultures they have other names."

When it comes to the black hole we saw this week, Hawaii Hawaiian Hawaii University, Larry Kimura, strengthened even before the photo was revealed.

Powehi (pronounced poh-veh-hee) is Hawaiian name of a black hole, not his official name, explained Jessica Dempsey, who helped to capture the image of a black hole as deputy director of the telescope James Clerk Maxwell at Mauna Kei, the highest mountain of Hawaii.

Asked about Kimura's idea, IAU board member Pasachoff said: "This is the first thing I've heard of this."

Eric Mamajek, chairman of the IAU Working Group on Star Names, called it a "wonderful, thought-out name."

But Mamajek said that his committee might not be right to give a black hole a name. Only stars.

"It's exactly Pluto's situation," Pasachoff said.

In 2006, the IAU's astronomers discussed the designation of a large object in our solar system, eventually called Eris. It is not considered a planet, so it was not the task of a planetary committee.

Some experts, however, emphasized that it was larger than Pluto, which added some confusion.

The conference decided to redistribute planets, shoot Pluto from a club of regular planets and join a newly established dwarf planet with Eris, Pasachoff said.
