Are using astrophizist James Web Space Telescope (JWST) captured the longest and most detailed look ever Sagittarius A*Supermasive Black Hole in the center of Milky Way Galaxy.
Of course, it is impossible to see directly in a black hole like Dhanu A* because its gravitational force is so strong that even the light cannot survive it. However, as is done Exhibited Through projects such as the event Horizon telescope, it is possible to locate and see a black hole through their effects on the surrounding cases and their effects on the intersteller content.
It is exactly what JWST did. Using a powerful $ 10 billion space telescope, using a nircam, which can inspect two different infrared wavelengths for the expanded period, scientists by scientists eight to 10-hour increase in a year In a total of 48 hours of comments visited the area around Sagitrius A*. , This allowed researchers to see how the black hole changed over time. Although even a year does not blink an eye in the cosmic timeline, the supermasive black hole proved to be surprisingly active.
‘This timelaps video compresses about 9 hours infrared comments in 30 seconds by NASA’s James Web Space Telescope. The web visited the black hole at the center of the Milky Way, known as Dhanu A* (A-Star). The web detected both unconscious Flickr and Bright Flaures (one of which is seen near the end of the video). These brightness can lead to two different processes, ‘Web Space Telescope Team’ Tell me,
The comments showed that “the ongoing fireworks of various brightness and duration,” and the spinning disk around the black hole (a dusting disc) produced an average of five to six “big flares” on an average each day, many of which many of which many of which were several In between with relatively minor flares.
“In our data, we have seen the shining,” says Farahad Yussef-Zadeh, Professor of Physics and Astronomy at Venberg College of Arts and Scientists, Northwestern University, “In our data, we have constantly changed, bubbling shine,” StudyWhich was published in this week The astrophizical journal letters,
“And then boom! A big burst of shine suddenly became pop up. Then, it calmed down again. We could not find a pattern in this activity. It appears to be random. The activity profile of the Black Hole was new and exciting every time we saw. ,
Sagittarius A* emits flarers of different intensity continuously. The new comments will help scientists better understand the nature of the black hole how they interact with the surrounding case, and possibly even how the Milky Way developed.
“Flairs are essentially expected to be in all supermasive black holes, but our black hole is unique,” Usef-Zadeh explains. “It always bubbles with activity and never reaches a stable position. We observed black holes several times in 2023 and 2024, and we saw changes in every observation. We saw something different every time, which is really notable. Nothing has ever been the same. ,
perfect Why Sagittarius A* behaves as it is that it is unknown, although Dr. There are principles of astronomers such as Yasef-Zadeh. They suspect that two different processes regularly run unconscious flarers and long, bright people.
“If the granship disc is a river, small, unconscious flickers are like small waves that randomly randomly on the surface of the river. For a long time, Ujjwal flares, however, are more like tide waves, due to more important events, “Northwestern University explains in one Press release,
“It is the same how the magnetic field of the Sun collects simultaneously, compressed and then a solar provokes,” says Yusaf-Zadeh. “Of course, processes are more dramatic because the environment around a black hole is much more energetic and much more extreme. But the surface of the sun also bubbles with activity. ,
The web captured these groundbreaking timeleps images as its nircam instrument simultaneously observes two different wavelengths, 2.1 and 4.8 μm. With data in these wavelengths, researchers found that the incidence of low wavelengths changed the brightness before long-waved incidence, which had made them before 40 seconds.
Videos below, edited by Space.com Using the data provided by the researchers, Timeleps shows data slightly differently.
The delay in this time is not only surprising, but can also provide significant insight into physical processes around supermasive black holes.
Yusaf-Zadeh and the rest of his team hope to use the web to see Vegitris A, even longer, perhaps even 24 hours. Prolonged observation will offer several benefits, including low noise.
“When you are looking at such a weak flare incidents, you have to compete with noise,” Yusaf-Zadeh commented. “If we can inspect for 24 hours, we can reduce the noise to see the characteristics that we were unable to see earlier. It will be amazing. We can also see if these flarers repeat themselves or if they are really random. ,
