Scientists at Japan’s National Astronomical Observatory have recently created a new map of the Milky Way galaxy. A map of the galaxy reveals that the Earth has been believed to be close to the supermassive black hole in the center of the galaxy for 2000 trust years which was previously thought. Researchers have also discovered that the Earth is orbiting black holes faster than estimated.
In 1985, the International Astronomical Union announced that Earth has 27,700 light-years from a black hole in the center of the galaxy, named Sagittarius A *. However, Japanese researchers conducted a 15-year analysis using the radio astronomy project VERA and found that Earth is 25,800 light-years away.
Research has also found that the Earth is 7 km faster than previously thought. / Sec Is orbiting at a speed of. Researchers are clear that the extra motion does not mean that the Earth suddenly leads to a black hole. Scientists say the new findings only offer a better model of the galaxy.
25,800 light-years is still a distance that is hard to wrap around his brain. At that distance, it would take 25,800 years to reach the black hole in the center of the galaxy. Researchers using the Vera Astrometry catalog created a location and velocity map of the interior of the galaxy and the center of objects inside the galaxy. This year the first astrometry catalog was published with data for 99 for budgets.
Positioning indicates that the Earth orbits the center of the galaxy, where the black hole resides, at 227 km / s. Scientists initially believed that the orbit was at a speed of 220 km / s. VRA is a very long baseline interferometric exploration of radio astronomy, and the project began in 2000 using interferometry to collect data from other radio telescopes in Japan.
