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.

The Israeli regime’s forces have killed two Palestinian children in the Gaza Strip every day since the ceasefire began in early October, UNICEF has warned.

The UN children’s agency said on Friday that Israeli forces continue to attack Palestinians in Gaza even though the agreement was meant to stop the killing.

“Since 11 October, while the ceasefire has been in effect, at least 67 children have been killed in conflict-related incidents in the Gaza Strip. Dozens more have been injured. That is an average of almost two children killed every day since the ceasefire took effect,” UNICEF spokesperson Ricardo Pires said in Geneva, reminding that each number in the statistics represents a child whose life had ended violently.

“These are not statistics,” he said. “Each child had a story, a family, and a future that was stolen from them.”

Data from Palestinian factions, human rights groups, and government bodies recorded since the US-brokered ceasefire deal went into effect on October 10 show that Israeli forces have carried out numerous attacks, each constituting a separate ceasefire violation.

UNICEF teams say they repeatedly continue to witness heart-wrenching scenes of fearful Palestinian children sleeping outdoors with amputated limbs, while others live as orphans in flooded, makeshift shelters.

“I saw this myself in August. There is no safe place for them. The world cannot normalize their suffering,” Pires said, lamenting that the UN could “do a lot more if the aid that is really needed was entering faster.”

The UNICEF spokesperson warned that with the advent of winter, the risks for hundreds of thousands of displaced children will increase.

He warned, “The stakes are incredibly high” for children as winter acts as a threat multiplier, where children have no heating, no insulation, and few blankets. He said respiratory infections rise.

“Too many children have already paid the highest price,” Pires said. “Too many are still paying it, even under a ceasefire. The world promised them it would stop and that we would protect them.”

“Now we must act like it,” the UNICEF spokesperson added.

Since the Israeli regime launched its genocidal war against Palestinians in Gaza in October 2023, it has killed nearly 70,000 people in the territory, most of them women and children, and injured over 170,000 more, while reducing most of the structures in the enclave to rubble.

A major upgrade in safety and monitoring is planned for Haj 2026, with every Indian pilgrim set to receive a Haj Suvidha smart wristband linked to the official Haj Suvidha mobile app. The initiative aims to support pilgrims—especially senior citizens—who may struggle with smartphones during the 45-day journey.

What the Smart Wristband Will Do

Officials said the device will come with:
•    Location tracking
•    Pedometer
•    SOS emergency button
•    Qibla compass
•    Prayer timings
•    Basic health monitoring

SP Tiwari, secretary of the UP State Haj Committee, said the goal is to make the pilgrimage safer and more comfortable.

“Most Hajis are elderly and not comfortable with mobile apps,” he said. “The smartwatch will help locate pilgrims who forget their way or cannot communicate their location.”

The wristbands will be monitored by the Consulate General of India in Saudi Arabia, similar to mobile tracking via the Haj Suvidha App.

Free Distribution and Training

•    Smart wristbands will be given free of cost.
•    Training for pilgrims will be conducted between January and February 2026.
•    Sample units will reach state Haj committees soon.
•    Final devices will be distributed as pilgrims begin their journey.

New Rules for Accommodation

Two major decisions have also been finalised for Haj 2026:
1.    Separate rooms for men and women – including married couples. They may stay on the same floor but must occupy different rooms, following stricter Saudi guidelines.
2.    Cooking banned – gas cylinders will not be allowed; all meals will be provided through official catering services arranged by the Haj Committee of India.

These decisions were finalised during a meeting of the Haj Committee of India and state representatives in Mumbai.

Haj Suvidha App Launched Earlier

The government launched the Haj Suvidha App in 2024, offering:

•    Training modules
•    Accommodation and flight details
•    Baggage information
•    SOS and translation tools
•    Grievance redressal

Haj 2026 Quota and Key States

•    India’s total Haj quota for 2026: 1,75,025 pilgrims
•    70% (1,25,000) allotted to the Haj Committee of India
•    30% (around 50,000) reserved for Haj Group Organisers

Uttar Pradesh has the largest allocation (around 30,000 seats), though approximately 18,000 pilgrims are expected to go this year. States with high pilgrim numbers include Kerala, Maharashtra and Gujarat.

Dates of Haj 2026

The pilgrimage is scheduled to take place from 24 May to 29 May, 2026 (tentative).
Haj is one of the five pillars of Islam and is mandatory for Muslims who meet the required conditions.

New Delhi, Dec 5: IndiGo CEO Pieter Elbers issued a public apology this evening after more than a thousand flights were cancelled today, making it the "most severely impacted day" in terms of cancellations. The biggest airline of the country cancelled "more than half" of its daily number of flights on Friday, said Elbers. He also said that even though the crisis will persist on Saturday, the airline anticipates fewer than 1,000 flight cancellations.

"Full normalisation is expected between December 10 and 15, though IndiGo cautions that recovery will take time due to the scale of operations," the IndiGo CEO said. 

IndiGo operates around 2,300 domestic and international flights daily.

Pieter Elbers, while apologising for the major inconvenience due to delays and cancellations, said the situation is a result of various causes.

The crisis at IndiGo stems from new regulations that boost pilots' weekly rest requirements by 12 hours to 48 and allow only two night-time landings per week, down from six. IndiGo has attributed the mass cancellations to "misjudgment and planning gaps".

Elbers also listed three lines of action that the airline will adopt to address the issue.

"Firstly, customer communication and addressing your needs, for this, messages have been sent on social media. And just now, a more detailed communication with information, refunds, cancellations and other customer support measures was sent," he said.

The airline has also stepped up its call centre capacity.

"Secondly, due to yesterday's situation, we had customers stranded mostly at the nation's largest airports. Our focus was for all of them to be able to travel today itself, which will be achieved. For this, we also ask customers whose flights are cancelled not to come to the airports as notifications are sent," the CEO said.

"Thirdly, cancellations were made for today to align our crew and planes to be where they need to start tomorrow morning afresh. Earlier measures of the last few days, regrettable, have proven not to be enough, but we have decided today to reboot all our systems and schedules, resulting in the highest numbers of cancellations so far, but imperative for progressive improvements starting from tomorrow," he added.

As airports witnessed chaotic scenes, the Directorate General of Civil Aviation (DGCA) stepped in to grant IndiGo a temporary exemption from stricter night duty rules for pilots. It also allowed substitution of leaves with a weekly rest period. 

Civil Aviation Minister Ram Mohan Naidu has said a high-level inquiry will be ordered and accountability will be fixed.
