There are numerous black holes in our universe and our galaxy Milky Way also hosts a super-massive black hole sitting in the heart of the galaxy. Now for the first time ever, astronomers were successful in detecting magnetic field outside the event horizon of the black hole.

Study co-author Shep Doeleman, assistant director of the Massachusetts Institute of Technology's Haystack Observatory, said in a statement that there have been predictions about existence of these magnetic fields but no one ever has seen them before. Their data has put together decades of theoretical work on solid observational ground.

As per experts, supermassive black holes exist at core of most of the galaxies in our solar system. Sagittarius A* the black hole in the heart of our Milky Way galaxy is located about 25,000 light-years away from earth. It is about 4 million time larger than that of our sun, but it has been found that its event horizon, a point beyond which not even light can escape, is just 8 million miles (12.9 million kilometers) wide.

The study scientists said they studied Sagittarius A* using the Event Horizon Telescope (EHT), which is a system of radio dishes around the world that are linked to form large instrument, which is sensitive enough to resolve features as small as 15 micro-arcseconds.

Scientists said the instrument detected the polarized light emitted by electrons around the black hole, which helped them trace the structure of the black hole’s magnetic field.
