A mysterious object with a mass 50 times that of Earth has appeared near the supermassive black hole at the center of the Milky Way and has been growing steadily for the past 20 years.
The researchers estimatethis mysterious object will disappear at the end of 2036 when it approaches and is swallowed up by the black hole Sagittarius A* Exists right in the center of the Milky Way.
This object was named X7here maybe a cloud of dust and gas Formed from the collision of two stars in space.
Black holes are also called “space monster” predicted by scientist Einstein’s theory of general relativity. It forms when a large star dies, leaving behind a small, dense core of material.
If this nuclear core has about 3 times the mass of the Sun, its gravitational force will overcome all other forces and form a black hole.

In fact, when matter or objects in the universe cross the horizon of a black hole, everything will be sucked in, including light, by its gravity.
Scientists cannot directly observe black holes with telescopes, but can only infer their presence through effects such as the disappearance of matter from objects or points of light in the universe. The pillar is proof that a black hole is swallowing it.
The research team from the Keck Observatory in Hawaii (USA) and UCLA discovered its development using near-infrared images taken by a powerful telescope system.
More precisely, the X7 object is constantly evolving and currently has a length 3000 times greater than the Earth-Sun distance.
Anna Ciurlo, assistant research scientist at UCLA, said: “X7 started out as a comet; we initially thought it might have been formed by stellar winds or particle jets from a black hole. But as the team monitored X7 over the Over the last 20 years, we’ve seen this happen… endlessly.”
Until now, the origin of X7 is still a matter of debate, researchers suggest that it could be a cloud of dust and gas ejected by the collision of two stars.
The black hole will swallow up X7 in 13 years

In a press release published this Monday, scientist Anna Ciurlo underlined: “This is a unique opportunity to observe the tidal forces of a black hole at high resolution, which will give us insight into the physics of the extreme environment at the center of the galaxy.”
Tidal force is the gravitational force that stretches an object as it approaches a black hole; The edge of the object closest to the black hole is attracted much more strongly than the side furthest away.
Co-author Randú Campbell, of the Keck Observatory, explains: “It is exciting to see in detail the dramatic changes in the shape and dynamics of X7 over a relatively short period of time, as the gravity of the supermassive black hole at the center of the Milky Way affects this object.”
The research team will continue to monitor X7’s dramatic changes and watch this object complete its life cycle under the power of a black hole in the heart of our Milky Way.
