Scientists take first picture of a supermassive black hole located in the center of the Milky Way

The heart of our galaxy’s home

The world is being gifted the second-ever image of a supermassive black hole -This time, it’s a hole that’s quite near to us. Today, scientists working on the huge Event Horizon Telescope (EHT) project shared a picture of Sagittarius A*, the gigantic black hole spinning in the middle of our galaxy, known as the Milky Way.

The celestial object is part of the same program that caused quite a stir in 2019 when they published the first photograph of a dark hole. This now iconic fuzzy image of the supermassive black holes that lie located in the middle of a giant galaxy named Messier 87, or M87 situated 55 million light years away from Earth. The breakthrough result allowed scientists to determine the circularity of these objects, and also further prove Einstein’s general relativity theory in which Einstein predicted the existence of black holes.


The team has returned with a new image of a black hole, this one within our own backyard. About 26,000 light-years away far from Earth, Sagittarius A* is also known as Sgr A* is believed to have approximately 4-million times as massive as our Sun. Scientists have speculated about its location in the middle of the galaxy for a long time by studying the way objects travel around the black hole. However, this marks the first occasion that we have a precise image of its shadow further evidence of the existence at the nexus of our galaxy’s cosmic neighbors.

Each time a new supermassive black hole image we receive scientists are able to learn a more about these fascinating objects. “These supermassive black holes, we don’t really know how they formed or grew so large,” Meredith Clark Powell is a black-hole research scientist from Stanford University, said “So it’s a very active area of research.”In reality, it is impossible to take a picture of a black-hole directly.

 Black holes, because of their nature, cannot easily be “seen,” as these objects are so massive that everything is able to resist their gravity pulleven light. However, it is possible to see the shapeof black holes. If a massive black hole is enclosed by a swirling disc of dust and gas the material will appear bright because the dust and gas are speeded up as well as heated due to the strong gravitational force of the hole nearby. What EHT actually captures is the shadow of the blackhole against the backdrop of the glowing dust and gas.

Photographing the black hole

Photographing the black hole shadows isn’t easy However, it is a challenge. To capture a photo similar to this one that of Sagittarius A*, a single telescope must be about the size of the planet Earth to accomplish the task according to Event Horizon Telescope group. 

Because the construction of such a device isn’t realistic, scientists created a way to work around it. It’s called the EHT is a vast range of dishes that are spread across five continents. The radio telescopes cooperate to look at the same object, acting as if they were one huge planet-sized telescope. It is then scientists at EHT scientists to put together the data that the telescopes have collected to form an image.

EHT employed the same method to record M87. Eight EHT radio dishes spent the week looking at the black hole in April 2017; this led to months and years of effort to put the data into an image that was released. At the same time, EHT also observed Sagittarius A* however, the process of creating its image proved much more difficult and laborious.

While it’s much closer in proximity to Earth than M87’s dark hole, however, Sgr. An*’s is much smaller and less active. Additionally, the surrounding material is dim, which makes it more difficult to observe. In addition what does encompass Sgr A* shows strange flaring when particles that surround the black hole accelerate to higher energies. Although it creates an intriguing light show it alters the composition of the black holes each several hours, which makes it difficult to see as time passes.

Additionally to that, Sir . A* is located in our own galaxy, making it difficult to observe from Earth. The process of observing this black hole involves looking across space and time in the Milky Way — and all the gaseous matter between our galaxy and that black hole. This creates an array of disturbances that scientists have to deal with.
