Mysterious radio signals discovered in ‘unprecedented’ part of space

Published

Story by Wiliam Hunter

 

Over the last 10 years, Earth has been receiving a mysterious radio signal every two hours from a distant region of space.

Although it sounds like the start of a sci-fi novel, scientists have now traced these pulses back to an ‘unprecedented’ source.

The researchers say that the pulses originate from a binary system containing a long-dead star.

In this system, a white dwarf and red dwarf orbit each other so closely that their magnetic fields ‘bump together’ to create a long radio pulse.

Since the stars’ orbit is regular, they produce a pulse every 125 minutes like a vast cosmic clock.

Researchers say this system, named ILTJ1101, is located 1,600 light-years from Earth in the direction of the Big Dipper, within the constellation Ursa Major.

This is the first time that a repeating long radio pulse has been observed coming from anything other than a highly magnetised neutron star, known as a magnetar.

In the future, the researchers believe that more mysterious signals from space might turn out to be binary systems like this one.

Dr Iris de Ruiter, now of the University of Sydney, first discovered the mysterious pulses in 2024 while looking through an archive of data from a radio telescope in the Netherlands.

Within the data of the Low Frequency Array (LOFAR), the largest radio telescope operating at the lowest frequencies that can be observed from Earth, Dr de Ruiter discovered a pulse arriving at Earth in 2015.

Sifting through the archival data for the same area of the sky, she soon found six more pulses.

What was unusual was that each pulse, like a flash of light from a torch but in radio form, lasted between a few seconds to a minute and arrived at regular intervals.

As radio-astronomy techniques have improved, scientists are spotting more and more ‘fast radio bursts’ (FRBs) but this kind of slow, regular pulse remain rare.

Study co-author Dr Charles Kilpatrick, of Northwestern University, says: ‘The radio pulses are very similar to FRBs, but they each have different lengths.

‘The pulses have much lower energies than FRBs and usually last for several seconds, as opposed to FRBs which last milliseconds.

To learn more about where these pulses were coming from, the researchers accessed a large optical telescope, which would gather light from that region of space.

While regular radio pulses have been theorised to be signs of intelligent life, the researchers say this pulse is produced by the magnetic fields of the two stars bumping together as they orbit (stock image)

 

Starting a decade ago, scientists detected a regular radio pulse arriving once every 125 minutes from a distant region of space. Until now, the origin of this pulse has been a mystery. This diagram shows how the orbital period of the binary system (blue) matches the radio pulses

 

At first, only one star was visible, but the data soon revealed more about this strange system.

By looking at the optical spectra of the star – the different frequencies of light that reach the telescope – the researchers learned that the one visible star was a red dwarf.

Red dwarfs are small, cool stars just a fraction the size of the sun, which can burn for trillions of years without using up all their fuel.

However, this particular red dwarf was doing something unusual: it was wobbling back around a central point on a regular schedule.

Dr Kilpatrick says: ‘The spectroscopic lines in these data allowed us to determine that the red dwarf is moving back and forth very rapidly with exactly the same two-hour period as the radio pulses.’

This back-and-forth movement suggests that the red dwarf was being pulled by the gravity of a second, hidden star.

By observing those movements carefully, Dr Kilpatrick calculated that this second star had the same mass as a typical ‘white dwarf’ star.

White dwarfs are dead stars which have burned through all their nuclear fuel and shed their outer layers, leaving behind nothing but their hot, dense core.

The system includes a white dwarf, a dead star so small and faint that they don’t usually show up on optical telescopes. The researchers were only able to determine the white dwarf existed because of its pull on its partner star. Pictured: Artist’s impression of a white dwarf next to our moon for scale

 

But, since these stars are so dim, they don’t show up on any but the most powerful telescopes – which explains why the researchers couldn’t directly observe it.

The researchers believe that, as the white and red dwarfs dance around a central point, their magnetic fields come close enough to interact and produce a blast of radio waves.

Around 1,600 years later, those radio waves arrive on Earth as the mysterious radio pulses which showed up in Dr de Ruiter’s database.

Dr Kilpatrick says: ‘In almost every scenario, its mass and the fact that it is too faint to see means it must be a white dwarf.

‘This confirms the leading hypothesis for the white dwarf binary origin and is the first direct evidence we have for the progenitor systems of long-period radio transients.’

Going forward, the researchers hope that their study will inspire other astronomers to consider binary systems as the possible source of unusual radio pulses.

This could help us understand many of the mysterious energy sources which have been found throughout the Milky Way.

Lead author Dr de Ruiter says: ‘With different techniques and observations, we got a little closer to the solution step by step.’

SEE VIDEO: MIDNIGHT CARNAGE IN LILU: GUNMEN RAZE ANGLICAN CHURCH, KILL PRIEST’S WIFE AND ONE OTHER

The quiet community of Lilu in Ihiala Local Government Area of Anambra State was thrown into mourning on Sunday after armed assailants launched a devastating midnight attack on St. Andrews Anglican Church, leaving two people dead—including the wife of the resident priest—and destroying several buildings within the church premises.

The attackers reportedly stormed the church compound in the early hours of the morning, firing sporadically and setting fire to multiple structures. The assault came just as some early worshippers were preparing for the day’s service. Witnesses said the gunmen moved with brutal precision, torching vehicles, the priest’s residence, and other facilities as frightened residents fled for safety.

By Monday morning, when journalists arrived to assess the destruction, what was once a vibrant centre of worship had been reduced to ruins. Charred vehicles, shattered roofs, burnt personal items, and lingering smoke told the story of a night filled with terror. The church compound, normally bustling with worshippers, stood eerily quiet—its silence a stark reminder of the violence that occurred.

One eyewitness, still visibly shaken, recounted the chaos:
“They came in shooting everywhere. Everything was burning—cars, buildings, even the priest’s house. The priest’s wife and one other person were killed. Many were injured. It was like something from a nightmare.”

Residents expressed deep concern over the severity of the attack and lamented the lack of nationwide attention to what they described as a direct assault on their community and faith.

Meanwhile, the Anambra State Police Command confirmed the tragic incident. Police spokesperson SP Tochukwu Ikenga said Commissioner of Police, CP Ikioye Orutugu, had strongly condemned the violence, calling it “utterly wicked and intolerable.” He noted that the CP has ordered intensified intelligence operations, strengthened joint security deployment, and enhanced surveillance across the area to prevent further occurrences.

Ikenga extended condolences on behalf of the Command to the bereaved families and the entire Lilu community. He urged residents to remain calm and cooperate with ongoing investigations as security agencies move to track down the perpetrators.

Imo Govt shuts hotel, mortuary over alleged kidnapping, organ-harvest

Published

on

Imo State government has shutdown a hotel and a mortuary allegedly used for kidnapping and the harvesting of human organs.

The State Police Public Relations Officer, Okoye Henry, disclosed this in a statement shared via X handle on Sunday.

Henry said the operation was based on credible intelligence regarding a suspected criminal, Stanley Morocco Oparaugo, who remains at large.

According to the command, the action formed part of an ongoing crackdown on kidnapping and violent crimes along the Owerri–Aba Expressway, led by the Commissioner of Police, Aboki Danjuma, in collaboration with other security stakeholders.

“A hotel and a private mortuary owned by the suspect, allegedly used by kidnappers and violent criminals, were inspected.

“At the mortuary, decomposed and mutilated corpses were discovered in unhygienic conditions, raising suspicions of illegal organ-harvesting activities.

“Following these discoveries, both the hotel and mortuary were sealed on the directive of the State Government.

“The suspect’s residence was also searched, and crucial exhibits were recovered,” he said.

Nigerian Air Force Launches Coordinated Airstrikes Against Fleeing Coup Plotters in Benin Republic

Published

on

Nigeria has carried out a series of precision airstrikes against members of the failed military coup in the Benin Republic, neutralising several suspected plotters and destroying their escape vehicles.

 

The operation was executed on Sunday after the Nigerian Air Force (NAF), acting under a joint security arrangement with authorities in Cotonou, tracked the movement of key coup actors attempting to flee in armoured convoys. Intelligence reports had indicated that the fleeing soldiers were heading south toward coastal exit routes.

A senior security official confirmed the mission, saying it was “carefully coordinated with Benin’s leadership” to prevent the coup backers from regrouping and to support efforts to stabilize the country after the attempted takeover.

According to multiple security sources, the airstrikes—lasting approximately 30 minutes—targeted fast-moving convoys believed to be carrying loyalists of the coup leader, Lt. Col. Pascal Tigri. The fleeing soldiers reportedly departed the country’s interior in an effort to evade capture.

 

Residents in parts of Cotonou reported hearing loud explosions and seeing thick smoke rising from the outskirts, sparking speculation that foreign aircraft were involved in the crackdown on the mutineers.

 

The development was later confirmed by Agence France-Presse (AFP), which reported that Nigerian jets conducted the strikes in coordination with Beninese authorities working to contain the mutiny.

 

Speaking on the operation, Nigerian Air Force spokesperson Air Commodore Ehimen Ejodame said the mission was carried out “in line with ECOWAS protocols and the mandate of the ECOWAS Standby Force.”

 

Sources told POLITICS NIGERIA that the strikes successfully disabled multiple armoured vehicles and sealed off escape corridors identified by the fleeing troops. Although no official casualty figures have been released, security insiders disclosed that “a number of hostile elements” were eliminated.

“All sorties were flown with the consent of Beninese authorities and adhered strictly to international rules of engagement,” another official said, noting that planners were careful to avoid civilian areas and minimise collateral damage.

 

The air operation followed the unsuccessful attempt by Lt. Col. Tigri and his faction—known as the Military Committee for Refoundation—to dissolve state institutions and seize power. Loyalist forces in Benin swiftly regained control, forcing several of the coup backers to attempt a southern retreat before they were intercepted.
