Black hole into the earth's distance was much closer than expected in the sky is black awal.Lubang can suck celestial bodies including the earth and menghancurkannya.Sebuah ineternasionaltelah team of astronomers to accurately measure the distance of the earth into a black hole for the first kalinya.Tanpa rely on mathematical models of, astronomer obtain the results of 7800 the number of light years, much closer than the initial assumption. Researchers obtain data from the radio emission of black holes and dead stars in the area. With an error rate of the smaller studies (less than 6%), astronomers have mendapatka a clearer picture of how black holes evolve. Furthermore, the exact distance required to measure black hole spin. Astronomical distances more easily measured with an instrument called trigonometric parallax, in which astronomers use the annual shift of star positions as a result of Earth's orbit around the sun (parallax shift). Peter Jonker of the Netherlands Institute for Space Research SRON and colleagues applied this method for the first time, as an approximation to the black hole and associated star, V404 Cygni in the constellation Cygnus.
Outermost layer of the star has been concentrated into a black hole. Gas was first accumulate in plasma in a circle around a black hole before and then disappeared into it, a process that releases a lot of X-rays and radioactive waves. Jonker and his colleagues can measure the parallax shift is definitely in our binary system using a combination of telescopes spread across the earth that is High Sensitivity Array (HSA). Researchers believe that the previous calculation of black hole with the earth's distance is the absorption and decomposition of interstellar dust that can provide the degree of error of 50%. While this latest study the error rate of less than 6%. From the measurement results also found that black holes are formed from a supernova explosion and then the hole moves in outer space
