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.

Donald Trump has linked his repeated threats to seize Greenland to his failure to win the Nobel Peace Prize, in a letter to Norwegian Prime Minister Jonas Gahr Støre.

The authenticity of the letter, in which Trump says he no longer feels obligated to “think purely of peace,” was confirmed by Støre to the Norwegian newspaper VG.

“Considering your country decided not to give me the Nobel Peace Prize for having stopped eight wars plus, I no longer feel an obligation to think purely of peace,” Trump wrote, adding he can now “think about what is good and proper for the United States.”

Støre said Trump’s letter was in response to a short message he had sent earlier, on behalf of himself and Finland’s President Alexander Stubb.

Trump has escalated rhetoric toward Greenland, a self-governing Danish territory, insisting the US will take control “one way or the other.” Over the weekend, he tweeted: “Now it is time, and it will be done!!!”

On Saturday, Trump threatened a 10% tariff on imports from Denmark, Norway, Sweden, France, Germany, the UK, the Netherlands, and Finland from 1 February until the US is allowed to purchase the island. EU diplomats met for emergency talks on possible retaliatory tariffs and sanctions.

In his letter, Trump argued Denmark “cannot protect” Greenland from Russia or China, questioning Danish ownership: “There are no written documents; it’s only that a boat landed there hundreds of years ago.” He added that NATO should support the US, claiming the world is “not secure unless we have complete and total control of Greenland.”

Trump’s stance has unsettled the EU and NATO, as he refused to rule out military action to take control of the mineral-rich island.

The Nobel Peace Prize is awarded by the independent Norwegian Nobel Committee, not the government. Trump had campaigned for last year’s prize, which went to Venezuelan opposition leader María Corina Machado, who dedicated her award to him.

Støre reiterated that the Nobel Prize decision rests solely with the committee.

Following a record-breaking response to experimental joyrides during the Karavali Utsava, the Dakshina Kannada district administration has signaled a major shift toward high-end travel. Officials are now laying the groundwork to transform Mangaluru into a permanent heli-tourism hub, connecting the state’s most sacred pilgrim centers and untouched coastal gems via the skies.

The move comes as the Karnataka government readies a specialized tourism policy for the coast, aimed at drawing global investors. With Mangaluru already serving as a critical nexus for education, healthcare, and maritime trade, the introduction of a scheduled helicopter service is seen as the "missing link" in the region’s economic evolution.

By the Numbers: A Flying Success

The data from the recent 10-day trial (beginning December 26) paints a clear picture of high demand:

•    Total Passengers: 1,032
•    Ride Duration: 7 minutes
•    Ticket Price: ₹3,500 per person
•    Origin of Tourists: Significant turnout from Kerala, Udupi, and Karwar.

Bridging the Gap for Global Travelers

Deputy Commissioner Darshan HV emphasized that the vision extends far beyond festival joyrides. Currently, international tourists arriving via luxury cruises at the New Mangalore Port (peak season December–April) often find themselves "landlocked" by time.

"Foreign visitors staying for just 24 to 48 hours currently struggle to visit inland attractions like Chikkamagaluru or Kodagu due to road travel times," a senior official noted. "A permanent heli-link would make these Western Ghats destinations accessible in under 30 minutes."

Beyond Tourism: Medical and Logistics

The administration is also looking at the humanitarian and logistical benefits. As a medical powerhouse, Mangaluru’s private hospitals could utilize the proposed permanent helipads for:

1.    Cardiac Emergencies: Rapid transfer of critical patients.
2.    Organ Transplants: Vital "green corridors" through the air to save lives.
3.    Regional Connectivity: Linking remote areas like Puttur, Sullia, and Beltangady to the main city.

While the Karavali Utsava has traditionally focused on beach-side festivities, the DC confirmed that the district is now evaluating formal proposals from private operators. The goal is to establish a network of permanent helipads that will eventually offer regular sorties to Kudremukh National Park and the scenic heights of the Western Ghats.

Bengaluru: As the dust settles on the recent legislative session, the corridors of Vidhana Soudha are buzzing with more than just policy talk. A high-stakes game of political musical chairs has begun, exposing a deepening rift within the Congress party’s Muslim leadership as a major Cabinet reshuffle looms.

With the party hierarchy signaling a "50% refresh" to gear up for the 2028 Assembly elections, the race to fill three projected Muslim ministerial berths has transformed from a strategic discussion into an all-out turf war.

The "Star Son" Spark

The internal friction turned public this week following provocative remarks by Zaid Khan, actor and son of Wakf Minister Zameer Ahmed Khan. Zaid’s claim—that his father "helped" secure a ticket for Shivajinagar MLA Rizwan Arshad in 2023—has acted as a lightning rod for resentment.

Rizwan’s camp was quick to fire back, dismissing the comment as a desperate attempt by Zameer to manufacture seniority. "Rizwan’s political pedigree was forged in the NSUI and Youth Congress long before Zameer even stepped into the party," a supporter noted, highlighting Rizwan’s tenure as an AICC secretary and his two-term presidency of the State Youth Congress.

A Tale of Two Loyalists

While both Zameer Ahmed Khan and Rizwan Arshad are staunch allies of Chief Minister Siddaramaiah and represent Bengaluru strongholds, their political DNA could not be more different:

•    Zameer Ahmed Khan: A four-time MLA who crossed over from JD(S) in 2018. Known for his "overzealous" and often polarizing outreach during communal flashpoints—from the DJ Halli riots to the recent Wakf land notice controversy—his style has frequently left the Congress high command in a state of "discomfort."

•    Rizwan Arshad: A homegrown organizational man. Seen as a "quiet performer," Arshad represents the sophisticated, moderate face of the party, preferred by those who find Zameer’s brand of politics too volatile.

The Outsiders Looking In

The bickering isn't limited to a duo. The "Beary" community, represented by leaders like N A Haris and Saleem Ahmed, is demanding its pound of flesh. Saleem Ahmed, the Chief Whip in the Legislative Council, has dropped the veil of diplomacy, openly declaring his ministerial aspirations.

"I was the only working president not included in the Cabinet last time," Saleem noted pointedly, signaling that the "loyalty quota" is no longer enough to keep the peace.

As Chief Minister Siddaramaiah prepares to finalize the list, he faces a delicate balancing act: rewarding the aggressive grassroots mobilization of Zameer’s camp without alienating the organizational stalwarts and minority sub-sects who feel increasingly sidelined by the "Chamarajpet-Shivajinagar" binary.
