Two black holes orbiting each other for the first time

Two giant black holes in the galaxy 0402+379 orbiting each other have been discovered by scientists for the first time.

A group of American scientists in research published in the journalAstrophysical said thatdirectly observed two giant black holes 750 million light years from Earth orbiting each other,NewsweekJune 28 news.

Scientists used 10 radio telescopes across the United States to observe two black holes 12 years ago.Two giant black holes located in galaxy 0402+379, have a combined mass 15 billion times that of the Sun and take about 20,000-30,000 years to complete one orbit.

Scientists have long hypothesized that two black holes orbit each other, the result of a merger between two galaxies, although this astronomical phenomenon has never been detected before.

Because of the difference in the two black holes' speeds, researchers predict they will never merge even if the universe ends in billions or trillions of years. "Imagine a snail moving at 1 cm/s around the Earth-like planet Proxima Centaurifour light years away from us," study co-authorRoger W. Romani, professor of Physics at Stanford University, said.

The new discovery provides information about the time before two black holes collided, an astronomical event that sent gravitational waves across the universe. The discovery also gives people a glimpse into the future when the Andromeda galaxy is predicted to collide.Milky Wayin about 4 billion years.
