Astronomers spot flares of light near the black hole at the center of our galaxy

An artist’s illustration depicts the supermassive black hole at the center of the Milky Way galaxy, known as Sagittarius A*. It’s surrounded by a swirling accretion disk of hot gas and dust.

Astronomers using the James Webb Space Telescope have spied dynamic flares of light near the supermassive black hole at the center of the Milky Way galaxy. The constant, rapid-fire display includes seconds-long short flashes and longer, blindingly bright flares of light on a daily basis.

The Webb observations mark the longest, most detailed look researchers have been able to make around the Milky Way’s central black hole, called Sagittarius A*, building on past evidence of its highly energetic activity.

While black holes are invisible, the flares unleashed by the swirling disk of hot gas and dust, or accretion disk, that orbits Sagittarius A* resemble a pyrotechnic extravaganza. A study describing the findings was published Tuesday in The Astrophysical Journal Letters.

Astronomers believe the flares are coming from the inner edge of the accretion disk just beyond the black hole’s event horizon, or the area around a black hole where the pull of gravity is so strong that not even light can escape, according to NASA.

“In our data, we saw constantly changing, bubbling brightness,” said lead study author Farhad Yusef-Zadeh, a professor of physics and astronomy at Northwestern University’s Weinberg College of Arts and Sciences, in a statement. “And then boom! A big burst of brightness suddenly popped up. Then, it calmed down again. We couldn’t find a pattern in this activity. It appears to be random. The activity profile of this black hole was new and exciting every time that we looked at it.”

The observations could shed light on how black holes behave and the ways they feed on their surroundings.

The strong, gravitational influence of black holes pulls in gas and dust from any celestial object that wanders too close. The gas and dust swirl together at high speeds, forming the accretion disk that feeds the black hole. The rapid movement of the material causes it to heat up, releasing energy in the form of radiation as well as jets of material that don’t make it into the black hole.

The radiation and jets can change the way gas is distributed throughout galaxies and feed the formation of stars, which is why supermassive black holes are regarded as giant engines at the centers of galaxies.

Yusef-Zadeh and his colleagues observed Sagittarius A*, also called Sgr A*, for 48 hours over the course of one year in eight to 10-hour increments, using Webb’s Near-Infrared Camera to track the black hole’s activity. The team spied five to six big flares a day as well as smaller flashes of light in between.

“Flares are expected to happen in essentially all supermassive black holes, but our black hole is unique,” Yusef-Zadeh said. “It is always bubbling with activity and never seems to reach a steady state. We observed the black hole multiple times throughout 2023 and 2024, and we noticed changes in every observation. We saw something different each time, which is really remarkable.”

This composite image of nebula NGC 1333 captures minute detail of young stars and brown dwarfs. These details were previously obscured in Hubble Telescope's images of the same nebula.

The variability of the black hole’s activity is likely due to the random nature of the material flowing into the accretion disk, Yusef-Zadeh said.

The team believes the short bursts of light are created by minor, turbulent fluctuations within the accretion disk that could squeeze hot, energetic gas called plasma and cause a flash of radiation.

“It’s similar to how the Sun’s magnetic field gathers together, compresses, and then erupts a solar flare,” Yusef-Zadeh said in a statement. “Of course, the processes are more dramatic because the environment around a black hole is much more energetic and much more extreme.”

Meanwhile, the longer, bigger flares may occur due to magnetic reconnection events, or when two different magnetic fields collide near the black hole and release energetic particles moving near the speed of light.

“A magnetic reconnection event is like a spark of static electricity, which, in a sense, also is an ‘electric reconnection,’” Yusef-Zadeh said.

A ‘rainbow’ of activity
Webb’s capabilities enabled the team to observe the black hole’s flaring across two different wavelengths of light simultaneously.

“(It was like) seeing the world in color versus in black and white, and (we) found rainbows,” Yusef-Zadeh said. “This tells you about the nature of flaring activity and the physical characteristics of the radiation mechanism, the magnetic field and the density of flares more directly.”

The observations provide a deeper look at how the black hole’s activity varies in brightness over time, said Tuan Do, associate professor in the physics and astronomy department and deputy director of the Galactic Center Group at UCLA.

Do was not involved in this study but has led research on Sagittarius A* in the past, including when the black hole showcased unusual activity in 2019.

“Sgr A* got about half as bright in the new data as was seen in 2019, so I think that 2019 is still unusually active for the black hole,” Do said. “The black hole and its environment (are) always changing though so we are never sure what we’ll find! This is what makes observations of the galactic center so exciting, even though we’ve stared at this spot in the sky for decades now."

When the authors of the latest study observed the two different wavelengths of light from the black hole simultaneously, they realized the shorter wavelength changed in brightness just before the longer wavelength. The observation suggested that as the particles spiral around magnetic field lines, they lose energy more quickly.

The changes in brightness have been noted in previous research and recent complementary data from the Mid-Infrared Instrument on the Webb telescope and other observatories.

“I think the next big step would be to try to connect these different data sources together to form a fuller picture of the physics of the environment around the supermassive black hole,” Do said.

The new study also confirms the black hole has “non-stop variability,” as previously observed, said Mark Morris, distinguished research professor in the department of physics and astronomy at UCLA. Morris was not involved in the new study.

“X-ray astronomers see reasonably strong evidence that in the last few hundred years, there has been at least one, maybe two instances of enormous flares taking place,” Morris said via email, “with intensities (10,000 to 100,000) times larger than anything we’ve seen in the last quarter century that we have been closely examining Sgr A*.”

What might have caused these flares? Astronomers still don’t know, but it’s possible the black hole gobbled up a planet a few hundred years ago, Morris said.

This artist’s illustration shows the largest radio jet ever found in the early Universe. The jet was first identified using the international Low Frequency Array (LOFAR) Telescope, a network of radio telescopes throughout Europe. Follow-up observations in the near-infrared with the Gemini Near-Infrared Spectrograph (GNIRS), and in the optical with the Hobby Eberly Telescope, were obtained to paint a complete picture of the radio jet and the quasar producing it. GNIRS is mounted on the Gemini North telescope, one half of the International Gemini Observatory, funded in part by the U.S. National Science Foundation and operated by NSF NOIRLab. Historically, such large radio jets have remained elusive in the distant Universe. With these observations, astronomers have valuable new insights into when the first jets formed in the Universe and how they impacted the evolution of galaxies.

When the sun releases solar storms, scientists worry because such activity can potentially affect GPS, communications and the power grid on Earth. But at 25,000 light-years away, the highly energetic and variable activity of the Milky Way’s central black hole isn’t a concern, Morris said.

However, the Webb telescope observations allow researchers to understand what kind of “storms” are created when matter is compressed and heated as it is drawn toward the black hole.

“Beyond pure interest in the most dazzling fireworks that the universe can produce, those fireworks can have a profound effect on the evolution of the galaxies that they are in,” Morris said. “They can provoke or impede star formation on large scales, they can remove gas and clear out galaxies, leaving them unable to form stars.”

A longer look
The study authors don’t believe the black hole was experiencing an unusual spike in activity, but they want to observe Sagittarius A* for an uninterrupted 24 hours to be sure.

“We also can see if these flares show periodicity (or repeat themselves) or if they are truly random,” Yusef-Zadeh said.

Astronomers still don’t know how fast Sagittarius A* is spinning as it gobbles up matter, but longer observations could provide the data necessary to find the answer.

Ultimately, more data from Webb observations of Sagittarius A* could help astronomers simulate how accretion disks behave around black holes, as well as comparing the behaviors of less energetically active, black holes with more active ones.

Posers For Anambra Police Command Following The Escape Of Two Kidnap And Murder Suspects From Its Custody

Since my Facebook and Live interview with Superintendent Tochi Ikenga, the Anambra Police Command PPRO on Tuesday, 18th February 2024, to discuss the escape of two suspects from police custody who are linked to the kidnapping and murder of Anambra lawmaker, Late Hon. Justice Azuka, further shocking information has come to light. (Watch the interview here

https://www.facebook.com/share/v/1B3So37YjT/?mibextid=wwXIfr)

(1) The suspects already escaped before the current Police Commissioner, CP Ikioye Orutugu, fwc MNIPS Ph.D took over. Why wasn't the incident made public? This is scandalous.

(2) The current Police Commissioner was not aware of the incident until yesterday, Monday, 18/2/2025. This informed his directive to launch a manhunt for the escaped suspects and disciplinary action against the officers involved.

(3) We have information that the suspects did not escape from the Police cell but during an operation to arrest another gang member who kept their operational vehicle.

(4) Why didn't the former CP Itam brief CP Orutugu during handing and taking over about this?

(5) Is this a calculated attempt to sabotage the efforts of the Governor of Anambra State and the government over their ongoing onslaught to dislodge criminal elements in the state?

I intend to bring the PRO SP Ikenga Tochukwu back to myUche Nworahive show if he would oblige to respond to these posers.

Sowore is here again to use headless mob head to play ping pong... They can’t kuku think upright..

Karma is the one dealing with Igbos, not Nigeria. Adaka boro was the first to declared secession away from Nigeria. It was Ibos that frustrated the guy’s dream (Ojukwu, Ironsi). A year later, Ojukwu declared Biafra and he expected success? How? You spoilt someone’s dream then you expect you own dream to come to reality? Life doesn’t work like that..

There will never be anything like Biafra! It has always been a figment of imagination and it will always be..

Very well.

All those lawmakers who demanded bribes should be aware of one thing:

If the lid is not blown, you may get away with it. But once the lid is blown open, you are scarred for life. Recall a shining star in Kano who ruined his political career by collecting bribes to cover up a subsidy probe? Remember the senators who collected bribes from a former minister of education to pad his budget?

Always remember that ill-gotten money will finish. You either spend it completely, or you die and leave it behind. But a scarred name is eternal. Whenever your name is mentioned, it would be associated with graft.

As for this Binance guy, I have only one question for him: why didn't he expose these while he was in custody? Has he been healed of his leg pain then?

All of them are corrupt.

As for those asking how he could have exposed them: he had access to his lawyers, visitors and his Binance colleagues. It is not too hard to understand.
