![]() Although this will not happen soon, one scientist has figured out how to do it. To get a high enough resolution and consider this donut: whether it is glazed or filled with custard, you will need an Earth-sized telescope. The magnifying power of a telescope is limited by the size of its antenna. However, looking at any of these objects through a telescope is like trying to photograph a donut on the moon. Measuring 24 billion miles across and six and a half billion times the mass of the sun, it is one of the most famous black holes. There are also giant black holes, for example, in the galaxy Messier 87. The distance to it is 26 thousand light-years, so a space probe such as Voyager 1 will take more than 400 million years to reach it. The nearest supermassive black hole is Sagittarius A* (Sgr A*), which is located in the galactic center of the Milky Way. The real problem with visualizing black holes is not just blackness or glow. In fact, no one has ever seen a black hole. Scientists have calculated that it is possible to see a terrible boundary where photons are still orbiting the black hole, and a point where nothing can leave it - the event horizon.īut this is a theory. Paradoxically, black holes are among the brightest objects in the sky. And when matter rubs turbulently, it heats up to a billion degrees and glows. All the hot gas and stardust near black holes are trying to squeeze into a dense point, creating strong friction. There are other clues to the location of the black hole. For example, a black hole in the center of our Galaxy makes the luminaries behave like bacteria in a Petri dish. Over the years, astrophysicists and mathematicians have found Nobel-Prize-worthy ways to detect black holes by studying how they control the orbits of stars around them. However, scientists are never too surprised by the impossible. Since everything is involved in their gravitational field, they do not emit anything that our instruments could detect. Space photography has come a long way, but black holes are invisible to the human eye. Nevertheless, 100 years after Einstein’s pioneering theory, astronomers have estimated that there are more than 40 quintillion (40 000 000 000 000 000 000 000 000 000 000) black holes in the visible spectrum of the Universe. Even Einstein, whose General Theory of Relativity predicted the existence of black holes, considered this idea so radical and incredible that he had great doubts until the end of his life. The objects are infinitely dense, as if compressing the mass of the Earth to the size of a coin. It’s hard to imagine the concept of black holes. It is so bizarre that time can stop abruptly in it. So powerful that it can tear the stars apart. It is so strong that even the light cannot escape. Like an infinite gravity well, they represent a region of spacetime where so much mass is condensed into such a tiny space that gravity overcomes all known forces. The secrets of black holes are very deep. Black Holes: The Hurried Engines of our Universe This is the age when Moore’s law, machine learning and, finally, quantum computers can discover one of the most amazing and mysterious objects in the Universe. ![]() These two images, equally blurry but no less important, are part of the golden age of the “new astronomy”. Just a few months ago, the same team showed the long-awaited second image of a black hole in the center of our Galaxy. Black holes are voracious beasts that are among the most magical objects in space that are very difficult to photographĮverything changed in 2019, when a group of scientists combined several important points: proven astronomy techniques, excellent global cooperation and advances in data storage and computing to create the first ever image of a black hole. This is just a rough illustration of what they might look like, based on mathematical theory and fairly recent evidence for the existence of black holes. Almost every image of a black hole that we have seen is not a photograph.
