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, Nov 24: The original departure time of 11.10 pm was a distant memory for scores of Dammam-bound passengers at Mangaluru International Airport last Friday night, as their Air India Express flight was abruptly cancelled at the eleventh hour, sparking hours of frustration and chaos.

The flight, IX 885, initially scheduled to depart at 11.10 pm on November 22, was subject to two back-to-back reschedules—first pushed to 11.45 pm and then significantly postponed to 1.40 am—before the final, crushing announcement of cancellation was made. For the travellers, many of whom are likely expatriate workers with tight schedules, the last-minute change marked the beginning of a distressing ordeal.

"There was no drinking water, no food, and absolutely no proper guidance. We were left stranded like refugees," complained a stranded passenger.

According to multiple passenger accounts, the airline's ground staff failed to provide adequate support or essential amenities following the cancellation. Complaints poured in about the total absence of drinking water, food provisions, and any reliable guidance from the carrier's representatives. Travellers alleged they were left stranded for a considerable period, with no immediate arrangements or clear communication offered regarding accommodation or alternative travel to send them back home.

The incident has highlighted serious concerns over the carrier's contingency planning and customer service protocols during flight disruptions at one of India's key international gateways. The airline is yet to issue a comprehensive statement addressing the alleged lapse in passenger care.

Bengaluru, Nov 21: The Karnataka government is facing pressure to overhaul its employment system after a high-level Cabinet sub-committee recommended the complete phase-out of job outsourcing in government offices, boards, and corporations by March 2028. The move is aimed at tackling a systemic issue that has led to the potential violation of constitutional reservation policies and the exploitation of workers.

The Call for Systemic Change

With over three lakh vacant posts currently being filled through private agencies on an outsource, insource, or daily wage basis, the sub-committee highlighted a significant lapse. "As a result, reservations are not being followed as per the Constitution and state laws. It’s an urgent need to take serious steps to change the system. It has been recommended to completely stop the system of outsourcing by March 2028," the panel stated in a document.

The practice of outsourcing involves private companies hiring workers to perform duties for a government agency. Critics argue this model results in lesser salaries, a lack of social security benefits (otherwise available to permanent government employees), and a failure to adhere to the provisions of Articles 14 and 15 of the Constitution, which guarantee equality before the law and prohibit discrimination.

The 'Bidar Model' as a Stop-Gap Solution

To regulate the current mode of employment and reduce worker exploitation until the 2028 deadline, the government plans to establish workers’ services multi-purpose cooperative societies across all districts, following the successful "Bidar Model."

The Bidar District Services of Labour Multi-purpose Cooperative Society Ltd., which operates under the District Commissioner, is cited as a successful example of providing a measure of social security to outsourced staff. Labour Department officials argue this society ensures workers receive their due wages and statutory facilities like ESI (Employees' State Insurance) and PF (Provident Fund), in exchange for a 1% service fee collected from the employees.

legislative push and Priority Insourcing

The recommendations, led by the sub-committee headed by Law and Parliamentary Affairs Minister H K Patil, are set to be discussed at the next Cabinet meeting. The committee has proposed the introduction of the Karnataka Outsourced Employees (Regulation, Placement and Welfare) Bill 2025.

In a move addressing immediate concerns, Labour Minister Santosh Lad, a member of the sub-committee, has reportedly assured that steps will be taken over the next 2-3 years to insource workers in "life-threatening services" on a priority basis. This includes essential personnel like pourakarmikas (sanitation workers), drivers, electrical staff in the Energy Department, and Health Department staff handling contagious diseases. The transition aims to grant these workers the long-term security and benefits they currently lack under the outsourcing system.

New Delhi: Karnataka chief minister Siddaramaiah and deputy CM DK Shivakumar on Saturday put up a dramatic display of unity at a closely watched joint press briefing, firmly dismissing weeks of speculation about a power-sharing tussle within the Congress. With the high command nudging both leaders to sit together and settle the dust, the meeting became a political spectacle, ending with the duo declaring that there was “no confusion, no differences.”

Calling the reports of a rift “manufactured confusion,” Siddaramaiah said the talks had gone smoothly, even joking about their breakfast. “Breakfast was very good. All three of us enjoyed it,” he said. “We want to end this confusion once and for all. For local elections and for 2028, our mission is clear — Congress must return to power. There is no difference between me and DKS, not now, not before.”

He blamed the media for fuelling rumours and reiterated absolute adherence to the party leadership. “From tomorrow, let there be no confusion. What the high command says, we will follow.”

Siddaramaiah also assured that the Assembly session starting December 8 would run smoothly and vowed that Congress would take on the BJP and JD(S) “together.”

Shivakumar echoed the chief minister word for word, stressing loyalty and discipline. “People have given us a massive mandate. It is our duty to deliver,” he said. “This government was formed under Siddaramaiah’s leadership. We both have complete trust in the high command. If they tell me to wait, I will wait.”

He added that the two leaders had discussed strategy for the 2028 Assembly elections. “Whatever the CM says, I agree. We are loyal soldiers of the party. The party may be facing challenges nationally, but we will keep it strong in Karnataka.”

Shivakumar also said Siddaramaiah would soon visit his home for lunch or dinner — another symbolic gesture meant to underline their unity.

Both leaders later posted on social media describing the breakfast meeting as “productive” and focused on “Karnataka’s priorities.”

The BJP, however, rejected the show of camaraderie as “pure bunkum,” accusing Congress of trying to paper over an internal power struggle. But Siddaramaiah and Shivakumar insisted their united front would continue — and that there was “no confusion” within the state leadership.
