The sea fishing!Astronomers have new discoveries outside the galaxy

For the first time, astronomer discovered that the hibernation black hole outside the galaxy

A research team composed of American and European astronomers announced on the 18th that they first found a dormant star black hole in a galaxy adjacent to the galaxy.

The researchers wrote in the British "Nature · Astronomy" magazine published on the same day that the dormant black hole was named VFTS 243, located in the Dagen galaxy poison spider nebula, and the quality was at least 9 times the sun, about 160,000 light years from the earth.

Researchers said that dormant black holes in the vast universe are like a "sea fishing needle."

Black holes are a celestial body with a very small volume and great quality. Like a "swallowing mouth" of the universe, even light cannot escape and cannot be directly observed. Previous studies have shown that dormant black holes exist in the universe, but it is difficult to find because they are not high -intensity X -rays like many other black holes.

According to the United States Cable Television News Network, astronomers took 6 years and observed 1,000 large -quality stars with a large telescope in the Southern Observatory of Europe, and found that a star with a mass of about 25 times the sun was found around a certain "invisible" celestial body operation. , Run for about 10 days for a week. The analysis results show that the "invisible" celestial body is VFTS 243 dormant black holes.

According to Reuters, this dormant black hole was formed by a 20 -fold star in the sun.

Researchers said that they had never discovered dormant black holes in the galaxy. The United States Cable Television News Network quoted research content reports that more than a dozen discovery of the black hole double -star system in the past two years has been questioned. "Object is a black hole.

The chief author of the research report, Tormer Sharnal, researcher at the University of Amsterdam, Dutch, said that although he could not say that research was unattainable, none of the scholars participating in the research found that the study had "flaws". He welcomed his peers to review this discovery.
