NASA created this image showing the black hole (inset) in the galaxy

Galaxy NGC 1068 is shown in visible light and X-rays in this composite image

This close-up view taken by the NASA Hubble Space Telescope shows Galaxy NGC 1068 at the doughnut disk of gas and dust surrounding it in the clearest form yet.

A NASA spokesman said: "Nuclear Spectroscopic Telescope Array NuSTAR's high-energy X-rays eyes were able to obtain the best view yet into the hidden lair of the galaxy's central, supermassive black hole. 

"The most massive black holes in the universe are often encircled by thick, doughnut-shaped disks of gas and dust. This deep-space doughnut material ultimately feeds and nourishes the growing black holes tucked inside.

"This active black hole - shown as an illustration in the zoomed-in inset - is one of the most obscured known, meaning that it is surrounded by extremely thick clouds of gas and dust.

"Until recently, telescopes weren't able to penetrate some of these doughnuts, also known as tori."

Andrea Marinucci of the Roma Tre University in Italy is the lead author of a new Monthly Notices of the Royal Astronomical Society study describing the results.

She said: "Originally, we thought that some black holes were hidden behind walls or screens of material that could not be seen through." 

But, with its X-ray vision, NuSTAR recently peered inside one of the densest of these doughnuts known to surround a supermassive black hole at the center of the well-studied spiral galaxy NGC 1068.

It is 47million light-years away in the Cetus constellation.

The observations revealed a clumpy, cosmic doughnut.
