Webb telescope observes violence around Milky Way’s central black hole

By Will Dunham

WASHINGTON (Reuters) – The James Web Telescope of NASA offers the best look so far on the chaotic events that are revealed around the super black hole in the middle of the Milky Way, with a steady outbreak of light that interspersed with the bright bright glow where the materials are drawn inward By pulling the enormous gravity.

WEBB, which was launched in 2021 and began collecting data in 2022, enables astronomers to monitor the area surrounding the black hole – called Sagittarius A* or SGR A* – for long periods for the first time, allowing them to distinguish activity patterns. The area surrounding SGR A* was flowing with activity instead of staying in a stable condition.

The researchers have noticed a continuous involvement of light from the gas disk surrounding the black hole – called the accumulation disk. This palpitational appears to be emitted from very close materials from the horizon of the event, which is the point of no return, after which everything is withdrawn – stars, planets, gas, dust and all forms of electromagnetic radiation – to forget.

There were also torches from time to time – about one to three large 24 hours, with smaller shorts.

Astronomical physicist Farhad Yossif Zdi of North Westren University in Illinois, author of the author’s leader, said the author of the author, author of the author, the author, the main author of the author, the main author of the author, the author, the main author of the author, the main author of the author, the main author of the author, said, The main author of the author, the main author of the author, the author, the author, the main author of the The The ELTEVING International, “The accumulation disk is a very chaotic area full of turmoil, and gas becomes more chaotic and pressure with the approaching black hole, under extreme gravity.” The study was published on Tuesday in the letters of the Astronomical Physics Magazine.

Horse Bushous, the world of astronomical physics, said the Baltimore Space Telescope Institute.

While these explosions arise from a mechanism similar to the solar mechanism – which explodes hot molecules in space from our sun – they occur in a different environment of astronomical physics and at a large -scale active level.

Black holes are exceptionally dense with strong gravity that so light can not even escape, which makes watching them a great challenge. As such, the new notes are not from the black hole itself but rather from the substance surrounding it.

SGR A* has approximately 4 million times the mass of our sun and is about 26,000 light -years away from Earth. The optical year is the light distance per year, 5.9 trillion mile (9.5 trillion km).

Most galaxies have a super black hole in their heart. While the events that were observed about SGR A* exciting, this black hole is not active like some in the midst of other galaxies and is considered in a relatively calm condition.

The new results were based on a total of about 48 hours of SGR A* notes that were conducted by Webb for a year, in seven increases ranging from 6 hours to 9-1/2 hours, where the researchers obtained continuous brightness measurements around the black hole.

Notes provide an insight into how black holes interact with their surrounding environments. Yusef-Zadeh said that about 90 % of the cumulative disk material is located in the black hole while the rest is taken back to space.

This accumulated tablet of accumulated materials seems to be from the stellar winds of the nearby stars – the gas that is detonated from the surface of those stars – which is captured by the gravitational power of SGR A*, instead of the star who wandered very close to it and the researchers said that it was torn.

Astronomers were previously limited to obtaining a few hours of notes from Earth’s telescopes or about 45 minutes each time from the tropical Hubble telescope, giving them a gradual account. Webb also provides an advanced sensitivity to its NIRCAM, and notes have been made with different wavelengths within the infrared spectrum.

“It is long known that SGR A* often shines bright torches in many different wavelengths, from radio, to infrared, visual, to X -rays. But most of the previous notes, which were made from each of The land and the space said, Bushaus said that telescopes -based telescopes were only limited to being able to monitor SGR A* for a few hours at one time or was it Limited in its sensitivity, and therefore only discovered cross rays. “
