Scientists watch as a black hole destroys doomed object in our galaxy

Right now, at the center of our galaxy, a massive black hole is pulling objects apart like taffy.

And scientists now have rare views and images of this extreme cosmic event unfolding.

A thick cloud of gas and dust called ‘X7’ is rapidly approaching the supermassive black hole Sagittarius A*. A black hole has an almost unimaginable gravitational pull because its mass is so concentrated (if the Earth were crushed into a black hole, it would be less than an inch in diameter).Latest observations published in astrophysics journal(opens in new tab)revealing that X7 has been stretched. trillion milesIt is now 3,000 AU long. An astronomical unit is 93 million miles, or the distance between the sun and the earth.

The X7 doesn’t have much time left. The gravity of a black hole is relentless.

“X7 will be pulled away in the near future,” Anna Ciuro, an astrophysicist at the University of California, Los Angeles and lead author of the study, told Mashable. “We are lucky to observe it now.”

X7’s gigantic stretching shows the cosmic effects of black holes. The leading edge of the cloud is more affected by gravity than the tail, causing the cloud to stretch longer. By 2036, X7 will swing to its closest point of approach near Sagittarius A* and dissolve shortly thereafter. The wreckage then swirls around the black hole, heating up and releasing energy into space. Some of this matter inevitably falls into the black hole and never escapes. (Once an object passes through the boundary of a black hole, called the “event horizon,” there is probably no way for anything to escape, which means moving faster than the speed of light.)

“In the near future, it will pull away from the X7.”

In the first picture belowNow you can see that the X7 has been gradually stretched from 2002 to 2021. Astronomers made their observations using the WM Keck Observatory on the towering summit of Mauna Kea in Hawaii. The observatory has two of the world’s largest telescopes at 10 meters (about 33 feet) high. Across.

Below this graphic is an animation showing how X7 is pulled away and then destroyed as it approaches a supermassive black hole.

looking into the center of the galaxy

Observing an object like X7 as it crosses the center of the galaxy is very difficult. The center of the galaxy is densely packed with stars, gas, and dust that obscure much activity. But here are her four reasons why Ciurlo and her team were able to track down her X7.

• Telescope size: The larger the telescope, the higher the resolution and the sharper the details, especially for objects that are many light years away. WM Keck Observatory(opens in new tab)As mentioned above, there are two of the largest telescopes on Earth.

• Infrared display: The type of light we can see is called visible light and is difficult to see at the center of the galaxy. “When we look at the center of a galaxy, we’re looking through a lot of dust,” Ciurlo explained. “It blocks visible light.” We used an instrument that observes the light of Infrared travels at longer wavelengths than visible light and can slip through dense clouds of dust and gas.

• Adaptive optics: The Keck telescope uses a powerful technique called adaptive optics(opens in new tab)to remove the distortion that inevitably occurs when looking through the Earth’s turbulent atmosphere.

• Repeated Observation: By closely observing the galactic center, astronomers were able to track the changes and details of X7 as it approached the black hole.

Where did the X7 come from?

The immediate question is where X7, a cloud of gas and dust, originated. Researchers have two thoughts.

• It is possible that X7 separated from the larger gaseous structure and oriented its orbit toward Sagittarius A*.

• Alternatively, X7 may have been ejected into space when two stars came close. The stars may have passed nearby or even merged. When this happened, gas could have been ejected into space, forming X7.

Astronomers like Ciurlo will continue to see X7 cross the galactic center and enter the final year of the universe. This is a unique opportunity to observe violent events unfolding in deep space near a supermassive black hole in our galaxy.

“It’s a lot of fun to watch in real time,” said Ciurlo.
