Astronomers discover 83 supermassive black holes 13 billion light-years away

Washington, Mar 15: Astronomers have discovered 83 quasars powered by supermassive black holes 13 billion light-years away from the Earth, from a time when the universe was less than 10 per cent of its present age.

“It is remarkable that such massive dense objects were able to form so soon after the Big Bang,” said Michael Strauss, a professor at Princeton University in the US.

“Understanding how black holes can form in the early universe, and just how common they are, is a challenge for our cosmological models,” Strauss said in a statement.

This finding, published in The Astrophysical Journal, increases the number of black holes known at that epoch  considerably, and reveals, for the first time, how common they are early in the universe’s history.

In addition, it provides new insight into the effect of black holes on the physical state of gas in the early universe in its first billion years.

Supermassive black holes, found at the centers of galaxies, can be millions or even billions of times more massive than the Sun.

While they are prevalent today, it is unclear when they first formed, and how many existed in the distant early universe.

A supermassive black hole becomes visible when gas accretes onto it, causing it to shine as a “quasar.” Previous studies have been sensitive only to the very rare, most luminous quasars, and thus the most massive black holes.

The new discoveries probe the population of fainter quasars, powered by black holes with masses comparable to most black holes seen in the present-day universe.

The team used data taken with “Hyper Suprime-Cam” (HSC) instrument, mounted on the Subaru Telescope of the National Astronomical Observatory of Japan, which is located on the summit of Maunakea in Hawaii.

The researchers selected distant quasar candidates from the sensitive HSC survey data.

They then carried out an intensive observational campaign to obtain spectra of those candidates, using three telescopes: the Subaru Telescope; the Gran Telescopio Canarias on the island of La Palma in the Canaries, Spain; and the Gemini South Telescope in Chile.

The survey revealed 83 previously unknown very distant quasars.

Mangaluru, Dec 2: Mangaluru International Airport responded to a medical emergency late on Monday night. Air India Express flight IX 522, travelling from Riyadh to Thiruvananthapuram, was diverted to Mangaluru Airport after a passenger in his late 30s experienced a medical emergency on board.

The Airport’s Operations Control Centre received an alert regarding the passenger’s health condition. The airport activated its emergency response protocol, mobilising the airport medical team and coordinating with stakeholders including CISF, immigration, and customs. 

Upon landing, airport medical personnel attended to the passenger, assessed his condition, and arranged to shift him to a local tertiary-care hospital for further treatment. The passenger’s relatives accompanied the passenger, who incidentally received necessary medical care on board, which helped stabilise the situation.

Following the handling of the emergency, the flight departed for Thiruvananthapuram at 2:05 am on Tuesday.

"We appreciate the cooperation of all parties involved, and this incident reaffirms our ongoing commitment to prioritising passenger safety and readiness to respond to unforeseen emergencies with professionalism and care," the Airport spokesperson said.

Udupi district transformed into a sea of saffron and celebration on Friday, November 28, as Prime Minister Narendra Modi’s roadshow swept through the coastal temple town. Thousands of residents lined the streets, turning the event into a vibrant public spectacle filled with cheers, flags, and festive energy.

The procession route—from the helipad to the historic Sri Krishna Math—was decked with buntings, saffron flags, and multilayered security barricades. One of the district’s largest-ever security deployments was put in place for the high-profile visit, with over 3,000 police personnel on duty. The arrangement included ten SPs, 27 DSPs, 49 inspectors, 127 sub-inspectors, 232 assistant sub-inspectors, 1,608 constables, and 39 women staff.

Six platoons of the Karnataka State Reserve Police, six Quick Response Teams, bomb detection units, and dog squads were stationed across Udupi. Enhanced surveillance covered Adi Udupi, Bannanje bus stand, and the Sri Krishna Math parking zone, with combing operations carried out along the roadshow corridor.

At the 800-year-old Sri Krishna Math, preparations reached a ceremonial peak. Paryaya Puttige Math seer Sugunendra Teertha Swamiji said the Prime Minister would take part in the Laksha Kantha Geetha Parayana, a mass chanting of the Bhagavad Gita by one lakh devotees, and inaugurate the new Suvarna Teertha Mantapa.

“He will first offer floral tributes to saint-poet Kanakadasa and then unveil the golden covering over the Kanakana Kindi,” the seer said.

The Prime Minister will also receive a Poorna Kumbha welcome and have darshan of Lord Sri Krishna, Mukhyaprana Devaru, and the Suvarna Paduke. Union Minister Pralhad Joshi, Karnataka Governor Thaawarchand Gehlot, Minister Bairathi Suresh, Dharmadhikari D. Veerendra Heggade, and seers from the Ashta Maths are expected to join the ceremony.

Ahead of his arrival, the Prime Minister posted on X that he felt “honoured” to attend the spiritually significant gathering. “This is a special occasion that brings together people from different sections of society for a recital of the Gita. This Matha has a very special significance in our cultural life,” he wrote, noting the institution’s long-standing legacy rooted in the teachings of Sri Madhvacharya.

Israeli forces have pushed over the Syrian frontier, erecting a checkpoint and stopping vehicles in the southwestern city of Quneitra, in yet another breach of the Arab country’s sovereignty.

The violation took place on Sunday, when the troops made their way across the border, setting up the outpost near the Ain al-Bayda junction in northern Quneitra, Syrian outlets reported.

According to the al-Ikhbariya paper, an Israeli detachment positioned itself at the junction, halting cars and conducting searches.

The Syrian Arab News Agency (SANA) reported that three Israeli military vehicles then moved further into the northern countryside, deploying between the town of Jubata al-Khashab and the villages of Ofaniya and Ain al-Bayda. The agency added that a separate Israeli unit mounted a new incursion in the central region, approaching the villages of Umm Batina and al-Ajraf.

Residents said such activities have surged in recent months, pointing to Israeli advances onto farmland, leveling of extensive forested areas, arrests, and spread of mobile checkpoints.

The Israeli regime began markedly increasing its military aggression against Syria last year.

The escalation coincided with increasingly ferocious onslaughts throughout the country by the so-called Hay'at Tahrir al-Sham (HTS) Takfiri terrorist group, which the government of President Bashar al-Assad had confined to northwestern Syria. The HTS, however, managed to overthrow the government as the Israeli attacks would pummel the country’s civilian and defensive infrastructure.

Various reports have shown that, during the escalation, the regime conducted more than 1,000 airstrikes on the Syrian territory and over 400 ground raids into the south.

Following the collapse of the Assad government, Tel Aviv also widened its grip over the occupied Golan Heights by taking control of a demilitarized buffer zone, in defiance of a 1974 Disengagement Agreement. Earlier this month, senior Israeli officials, including Prime Minister Benjamin Netanyahu, visited the buffer zone, prompting expressions of alarm on the part of the United Nations.

The United States, the regime’s biggest ally, has, meanwhile, been fraternizing the HTS head Abu Mohammed al-Jolani amid the widely reported prospect of rapprochement with Tel Aviv.
