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.

Bantwal: A domestic dispute appears to have led to a violent confrontation in BC Road area, where the owner of a textile shop was allegedly attacked with a knife by his wife on Wednesday evening.

Krishna Kumar Somayaji, the owner of Somayaji Textiles, sustained serious injuries in the incident and was immediately taken to a hospital for treatment. He is currently receiving care in the intensive care unit and is reported to have survived the assault, according to police.

The Bantwal Town police have registered a case against Somayaji's wife, Jyothi KT, who has since been taken into custody.

Police stated that the complainant, Namita, an employee at the shop, reported the sequence of events. She stated that around 7 p.m. on Wednesday, the suspect entered the shop, wearing a burqa and disguised as a customer, before attacking Somayaji with a knife. The employee then transported the injured owner to a local hospital via an autorickshaw.

Superintendent of Police Arun K confirmed that an ongoing domestic dispute between Somayaji and his wife reportedly preceded the attack. Police noted that Jyothi KT had previously visited the shop and issued threats.

Based on the complaint, Bantwal Town police have registered a case under relevant sections of the Bharatiya Nyaya Sanhita (BNS) and the Indian Arms Act-1959. An investigation into the incident is currently underway.

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.

Udupi: A 40-year-old NRI from Udupi has reportedly lost more than Rs 12.25 lakh in an online investment scam operated through Telegram.

According to a complaint filed at the CEN police station, Leo Jerome Mendonsa, who has been working in Dubai for the past 15 years in computer accessories sales, maintains NRI accounts in Karkala and Nitte.

On November 12, 2025, Mendonsa was added to a Telegram group called Instaflow Earnings by unknown individuals. Users identified as Priya and Dipannita persuaded him to invest in “Revenue Tasks.” Initially, Mendonsa transferred Rs 1,100 multiple times and received the promised returns, encouraging him to continue.

On November 14, another user, Nishmitha Shetty, directed him to register on a website, digitvisionuoce.cc, and invest Rs 4 lakh in various shares. Over the next few days, he made multiple transfers totaling Rs 12,25,000, including Rs 50,000 via Google Pay, believing the scheme was legitimate.

After receiving the money, the alleged handlers stopped responding, and neither the invested amount nor the promised profits were returned.

The CEN police have registered a case under Sections 66(C) and 66(D) of the IT Act and Section 318(4) of the Bharatiya Nyaya Sanhita (BNS), and investigations are ongoing.
