But large is a relative term as well — current estimates place the size of the black hole at Astronomical Units AU or less. One AU is the average distance between Earth and the Sun, 93 million miles million kilometers. Some estimates even indicate that the black hole could be as small as the distance between Mercury and the Sun, just 28 million miles 46 million km. The Event Horizon Telescope makes use of a technique called Very Long Baseline Interferometry VLBI that requires several telescopes observing the same object from different locations to create highly detailed images of very, very small sections of the sky. The farther apart the telescopes are located, the greater the detail they can achieve. By creating a truly Earth-sized telescope, the project should be capable of imaging the space around a black hole in exquisite detail.

All rights reserved. After completing five nights of observations, today astronomers may finally have captured the first-ever image of the famous gravitational sinkhole known as a black hole. More precisely, the hoped-for portrait is of a mysterious region that surrounds the black hole. As the final observing run ended at a. As the last of the data arrived at project observatories, he watched celebratory comments come pouring in on a special chat line for radio astronomers and engineers. One noted that he was about to open a bottle of year-old Scotch.
Black Hole Pictures
Don't let the name fool you: a black hole is anything but empty space. Rather, it is a great amount of matter packed into a very small area - think of a star ten times more massive than the Sun squeezed into a sphere approximately the diameter of New York City. The result is a gravitational field so strong that nothing, not even light, can escape. In recent years, NASA instruments have painted a new picture of these strange objects that are, to many, the most fascinating objects in space. The idea of an object in space so massive and dense that light could not escape it has been around for centuries.
Black holes are objects in the universe with so much mass trapped inside their boundaries that they have incredibly strong gravitational fields. In fact, the gravitational force of a black hole is so strong that nothing can escape once it has gone inside. Not even light can escape a black hole, it is trapped inside along with stars, gas, and dust. Most black holes contain many times the mass of our Sun and the heaviest ones can have millions of solar masses.
