An extremely powerful telescope is giving people a rare view of a black hole.

Images drawn up by NASA show what scientists believe is a compact source of X-rays that sit near the black hole, called the corona, that has moved closer to the black hole over a period of just days.

As the corona shifted closer, the gravity exerted a stronger tug on the X-rays emitted by it. The resulting image captured by NASA's NuStar telescope shows a blurring and stretching of the X-ray light.

Scientists said they've never seen it happen to this degree and in such detail.

The black hole is about 324 million light-years from Earth.
