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.

IndiGo, India’s largest airline, is battling one of its worst operational disruptions in recent years, with hundreds of delays and cancellations throwing domestic travel into chaos.

Government data on Tuesday showed its on-time performance plunging to 35%, an unusual dip for a carrier long associated with punctuality.

By Wednesday afternoon, airports in Delhi, Mumbai, Bengaluru and Hyderabad had collectively reported close to 200 cancellations, stranding travellers across the country.

Crew Shortage After New Duty Norms

A major trigger behind the meltdown is a severe crew shortage, especially among pilots, following the rollout of revised Flight Duty Time Limitation (FDTL) norms last month.

The rules mandate longer rest hours and more humane rosters — a shift IndiGo has struggled to incorporate across its vast network.

Sources said several flights were grounded due to lack of cabin crew, while some delays stretched upwards of eight hours.

With IndiGo controlling over 60% of India’s domestic aviation market, the ripple effect has impacted airports nationwide.

IndiGo Issues Apology, Lists “Compounding Factors”

In a statement, IndiGo acknowledged the large-scale disruption:

“We sincerely apologise to customers. A series of unforeseen operational challenges — technology glitches, winter schedule changes, adverse weather, system congestion and updated FDTL norms — created a compounding impact that could not have been anticipated.”

To stabilise operations, the airline has begun calibrated schedule adjustments for the next 48 hours, aiming to restore punctuality. Affected passengers are being offered refunds or alternate travel arrangements, IndiGo said.

What the FDTL Rules Require

The FDTL norms, designed to reduce pilot fatigue, cap duty and flying hours as follows:
•    Maximum 8 hours of flying per day
•    35 hours per week
•    125 hours per month
•    1,000 hours per year

Crew must also receive rest equalling twice the flight duration, with a minimum 10-hour rest period in any 24-hour window.

The DGCA introduced these limits to enhance flight safety.

Hyderabad: 33 Flights Cancelled, Long Queues Reported

Hyderabad’s Rajiv Gandhi International Airport saw heavy early-morning crowds as 33 IndiGo flights (arrivals and departures) were cancelled.

The airport clarified on X that operations were normal, advising passengers to contact IndiGo directly for latest flight status.

Cancellations included flights to and from Visakhapatnam, Goa, Ahmedabad, Delhi, Bengaluru, Chennai, Madurai, Hubli, Bhopal and Bhubaneswar.

Bengaluru: 42 Flights Disrupted

Bengaluru’s Kempegowda International Airport recorded 42 cancellations — 22 arrivals and 20 departures — affecting routes to Delhi, Mumbai, Chennai, Hyderabad, Goa, Kolkata and Lucknow.

Passengers Vent on Social Media

Irate travellers took to X to share their experiences. One passenger stranded in Hyderabad wrote: “I have been here since 3 a.m. and missed an important meeting.”

Another said: “My flight was pushed from 1:55 PM to 2:55 PM and now 4:35 PM. I was informed only three minutes before entering the airport.”

Delhi Airport Hit by Tech Glitch

At Delhi Airport, the disruption deepened due to a slowdown in the Amadeus system — used for reservations, check-ins and departure control.

The technical issue led to longer queues and sluggish processing, adding to delays already worsened by staff shortages.

Historical Background

It’s on November 26, 1949, the Constituent Assembly of India formally adopted the Constitution.This date is commemorated to acknowledge the completion of nearly three years of drafting, debate, and refinement.

On January 26, 1950, the Constitution came into force, marking India’s transition from a dominion to a sovereign republic.

The date 26 January was chosen to honor the “Purna Swaraj” declaration made in 1930 that marked the relentless efforts & sacrifices of the many. 

Why Constitution Day is Celebrated

* To honor & remember the framers of the Constitution, especially Dr. B. R. Ambedkar, the Chairman of the Drafting Committee, & many others. 

* To remind the citizens of the values, responsibilities, and rights enshrined in the Constitution.

* To promote constitutional values & literacy among students, institutions, and the general public.

* To reaffirm the nation’s commitment to justice, equality, liberty, fraternity and secular values. 

Vision and Significance of the Constitution

It establishes the fundamental political and legal framework for the nation.

Defines the structure, powers and functions of:

    •    The Legislature
    •    The Judiciary
    •    Guarantees a comprehensive set of Fundamental Rights, including:

-Equality before law
-Freedom of speech & expression
-Protection of life and personal liberty
-Freedom of religion
-Embeds Directive Principles of State Policy, guiding governance toward social justice and welfare.
-Introduces Fundamental Duties to ensure civic responsibility among citizens.

Key Features Celebrated on Constitution Day

-The Indian constitution is considered one of the longest written constitutions of the world. It’s systematically drafted considering almost all aspects that properly fits to the country. 

-Blend of multiple global constitutional principles while staying rooted in Indian values and realities.

-Framework that balances Federalism, Secularism, Democracy and Rule of Law. This makes everyone-from President to common man-below the law & are equal in the sight of law. 

-Another feature is that it’s based on built-in mechanisms for amendments, ensuring the Constitution grows with changing needs.

Message of the Day

The core ethos of this  Constitution Day is not merely about looking back at history-it’s a reminder of the continuous duty to protect democratic values, respect diversity and uphold the principles that define India as a sovereign, socialist, secular and democratic republic.

Happy Constitution Day to all my compatriots

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.
