JAKARTA, shift id- Black holes have been mysterious from the start. Nobody knows what’s inside a black hole because nothing can get out of it after the enormous gravitational pull has allowed it to devour many things.
Not even light can escape from a black hole. And that is why black holes cannot be “seen” and can only be detected through their effect on the surrounding celestial bodies.
Sometimes black holes can “sneak in”. Supermassive black holes at the center of galaxies are easy to detect. Other? Not too much.
Scientists discovered such a subtle black hole when they studied the VFTS 243 system. It is a satellite galaxy in the Tarantula Nebula and orbits our Milky Way. It is 163,000 light years away from us.
Until now it was thought that all the light reaching us was caused by the blue and white stars in the system. As the scientists further studied the star, they found that it had a companion orbiting it. But nothing was visible when the star’s gravitational pull was detected.
The scientists, after further observations and calculations, concluded that there was a black hole around the spinning star. The star keeps a safe distance from the black hole because it does not lose mass due to the black hole. (nda)
