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.

New Delhi: Setting speculation to the rest, the CPI(M) has made it clear that it is open to have an electoral understanding with the Congress “to defeat” the Trinamool Congress and the BJP in West Bengal Assembly election even as it is all set to take on the grand old party in Kerala accusing it of “found wanting” in fighting the Hindutva forces.

The CPI(M) also said that it will contest the Tamil Nadu election “with DMK and its allies to defeat the BJP and its allies”, amid a section in the Congress triggering confusion about its participation in the M K Stalin-led coalition over demand over power-sharing and more seats. It is also willing to join hands with Congress and others in Assam and Puducherry to defeat the BJP.

The decisions came at a three-day meeting of the CPI(M) Central Committee in Thiruvananthapuram, which ended on Sunday after reviewing the poll preparations in the poll-bound states.

The CPI(M)'s decision came even as a section led by West Bengal Congress president Subhankar Sarkar is averse to tying up with the Left Front, claiming that their party is not benefitted by the electoral understanding. Both Congress and CPI(M)-led Left Front had electoral understanding in 2016 and 2021 Assembly elections and 2024 Lok Sabha polls.

Congress and the Left Front fought together for the first time in 2016 when Congress won 44 seats and the CPI(M) got 26. In 2021, the Left Front and the Congress drew a blank. In the 2024 Lok Sabha polls, Congress managed to win one seat while the Left did not win any. In the 2019 Lok Sabha polls, both fought against each other with Congress winning two and the Left none.

“In Bengal, the party will work for the defeat of both the TMC and the BJP, which are trying to polarise the society. We will try to rally all the forces that are ready to work against them,” the CPI(M) said in a statement without naming Congress by name. Senior leaders said there is no change in its strategy of pooling all non-BJP, non-TMC votes.

However, the party was critical of the Congress in Kerala where both will fight against each other.

The CPI(M) said it would "expose the BJP-led Union government’s denial of rightful dues to Kerala, the fiscal constraints imposed and the overall attack on federalism" as also "expose the failure of the Congress to effectively counter this attack on federalism, as the largest opposition party in the Parliament".

"The Congress, especially in Kerala, was found wanting in the fight against communal RSS-BJP, ideologically and this will also be exposed before the people," it added.

In Assam, it said, the CPI(M) will work for the mobilisation of all the anti-BJP parties and forces and defeat the rabidly communal and divisive BJP government. The Left parties are cooperating with Congress in the north-eastern state. In Puducherry, it said it will work for the defeat of the BJP alliance government.

Karnataka Governor Thaawarchand Gehlot read only three lines from the 122-paragraph address prepared by the Congress-led state government while addressing the joint session of the Legislature on Thursday, effectively bypassing large sections critical of the BJP-led Union government.

The omitted portions of the customary Governor’s address outlined what the state government described as a “suppressive situation in economic and policy matters” under India’s federal framework. The speech also sharply criticised the Centre’s move to replace the Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA) with the Viksit Bharat–Guarantee for Rozgar and Ajeevika Mission (Gramin) Act, commonly referred to as the VB-GRAM (G) Act.

Governor Gehlot had earlier conveyed his objection to several paragraphs that were explicitly critical of the Union government. On Thursday, he confined himself to the opening lines — “I extend a warm welcome to all of you to the joint session of the State legislature. I am extremely pleased to address this august House” — before jumping directly to the concluding sentence of the final paragraph.

He ended the address by reading the last line of paragraph 122: “Overall, my government is firmly committed to doubling the pace of the State’s economic, social and physical development. Jai Hind — Jai Karnataka.”

According to the prepared speech, the Karnataka government demanded the scrapping of the VB-GRAM (G) Act, describing it as “contractor-centric” and detrimental to rural livelihoods, and called for the full restoration of MGNREGA. The state government argued that the new law undermines decentralisation, weakens labour protections, and centralises decision-making in violation of constitutional norms.

Key points from the unread sections of the speech:

•    Karnataka facing a “suppressive” economic and policy environment within the federal system

•    Repeal of MGNREGA described as a blow to rural livelihoods

•    VB-GRAM (G) Act accused of protecting corporate and contractor interests

•    New law alleged to weaken decentralised governance

•    Decision-making said to be imposed by the Centre without consulting states

•    Rights of Adivasis, women, backward classes and agrarian communities curtailed

•    Labourers allegedly placed under contractor control

•    States facing mounting fiscal stress due to central policies

•    VB-GRAM (G) Act accused of enabling large-scale corruption

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.
