NEW DELHI: As the James Webb Space Telescope (JWST) begins science operations, Indian astronomers are ready to peer into the edge of the universe with the observatory. Astronomers from the Indian Institute of Astrophysics (IIA) in Bengaluru have developed a new model to trace exo-moons that have remained elusive to ground- and space-based telescopes.Exo-moons are natural satellites that revolve around exoplanets, which are orbiting stars, just as planets in our own Solar System revolve around the Sun. Astronomers will look for habitable exo-moons as they try to understand new worlds beyond our solar system.
A large number of exo-moons are expected to be present in the universe, and they may play a crucial role in the habitability of rocky exoplanets in the habitable zone of their host stars. While most exoplanets are detected through the photometric transit method, signals from exo-moons are too weak to detect, mainly because of their extremely small size.

Professor Sujan Sengupta of the IIA, along with his graduate student Suman Saha, has developed an analytical model that uses the radius and orbital properties of the host planet and its moon. The model uses their parameters and incorporates various possible orientations of the moon-planet-star system to model the photometric transit light curve of moon-hosting exoplanets.
They will use co-alignment and non-coalignment of the orbits of the planet and the moon as parameters to model all the possible orbital alignments for a star-planet-moon system. “Using these generic models and the analysis of photometric transit light curves of exoplanets that are being obtained by JWST, a large number of exomoons can be detected in near future,” the Department of Science and Technology said in a statement.
Astronomers across the world are looking for habitable planets that fall in the Goldilocks zone, which marks the distance between a star and a planet where temperatures are just optimum for water and life to flourish. According to the researchers, an exo-moon around a gas giant planet like Jupiter in the habitable zone of the host star where the temperature is appropriate for water to exist in a liquid state may harbour life.
“Under favourable alignment of moon-planet-star, such an exo-moon may also be detected by JWST,” they said in a statement.
So far, there have been 500 exoplanets that have been discovered outside our solar system, which have varied ranges when it comes to their composition and characteristics. These include small, rocky worlds like Earth, gas giants many times larger than Jupiter, and hot-Jupiters in scorchingly close orbits around their stars.These planets have been discovered using several ground-based and space telescopes, such as Kepler, CoRoT, Spitzer, and Hubble space telescopes. However, the natural satellites or exomoons around any of these planets still remain untraced, unlike our Solar System which is flooded with moons around its host planets. OVER

Govt. assures UN of readiness to introduce ‘vetting process’ for troops on overseas missions
Defence Secretary (retd.) Air Marshal Sampath Thuyakontha has discussed with UN officials in New York the deployment of Sri Lankan troops in Haiti, under a new UN authorised force, tasked with tackling heavily armed gangs operating in the violence ravaged country.
The UN is in the process of building up a force comprising approximately 5,500 officers and men for deployment in Haiti.
The Sri Lankan delegation included Sri Lanka’s Permanent Representative to the UN, former Chief Justice Jayantha Jayasuriya. The UN has tagged the deployment Gang Suppression Force (GSF).
According to the Defence Ministry, Sri Lanka negotiated a Memorandum of Understanding (MoU) regarding the GSF. Although Sri Lanka has contributed to UN-led missions, the proposed deployment differed due to the nature of the operation, sources told The Island.
The delegation has assured that all personnel, assigned for UN missions, including the proposed GSF deployment in Haiti, would be subjected to a comprehensive screening process, in line with UN standards. War-winning Sri Lanka has declared, in New York, that the country was in the process of developing, what the Defence Ministry here called, National Human Rights Vetting Mechanism in consultation with the UN Resident Coordinator in Colombo.
The US has backed the deployment of Sri Lankan troops under UN command. Various interested parties, over the years, protested against the deployment of Sri Lankan troops on the basis of unsubstantiated war crimes allegations.
Thuyakontha has assured that troops would maintain highest standards of discipline during overseas missions. Sri Lanka brought the war here to a successful conclusion in May 2009 against predictions of contrary outcome by so-called experts.
The US and Panama proposed the GSF to replace a Kenya-led multinational force undermined by a lack of funding. Its strength hovered around 1,000, rather than the desired 2,500. The U.N. Security Council authorised the 5,500 strong force on September 30, 2025, with the new power to arrest gang members.

Lawyers cannot be denied right to represent a suspect – Udaya
Sallay’s case:
Attorney-at-law Udaya Gammanpila yesterday (27) said a lawyer could not be deprived of his or her right to represent a client.
The former Minister and leader of Pivuthuru Hela Urumaya (PHU) Gammanpila said so addressing the media at the party headoffice at Pita Kotte. Gammanpila was responding to recent media reports that he had been prohibited from representing retired State Intelligence Service (SIS) Chief Maj. Gen. Suresh Sallay. Therefore, there was absolutely no basis for claims that he had been barred from meeting the retired officer, now named the third suspect in the Easter Sunday case, the ex-parliamentarian said.
Gammanpila emphasised that in terms of the Constitution a suspect’s right to be represented by a lawyer was recognised as a fundamental right. The Criminal procedure Code, too, guaranteed the suspect’s right to consult a lawyer, the ex-lawmaker said, pointing out that the Judicial Organisation Act underscored the same.
Declaring that the retired officer’s wife had named him as Sallay’s lawyer in a letter addressed to Director, CID, Gammanpila said that the courts, police and the Attorney General’s Department couldn’t under any circumstances interfere with his right to represent Sallay.
The CID arrested Sallay on 25 February and detained him under Prevention of Terrorism Act (PTA) for a period of 90 days. Sallay has filed a writ petition before the Court of Appeal through his lawyers, challenging his arrest and detention by the CID under the PTA.
Former Minister Gammanpila said that even if a Magistrate had the power to prohibit a lawyer from representing a particular suspect, such a course of action couldn’t be resorted to without giving the lawyer concern an opportunity to explain his/her actions.
Declaring that in case of misconduct on the part of a lawyer only the Supreme Court could take disciplinary action, the PHU leader said, adding that he sought a certified copy of the proceedings of the day when a section of the media reported the Magistrate’s declaration of the purported ban. Gammapila said that he was really keen to know what happened during the proceedings on that day.
Sallay served as Director, Directorate of Military Intelligence (DMI) from 2012 to 2016 and received the appointment as head of SIS following the 2019 presidential election. Sallay held that appointment till early October, 2024.
Gammanpila said that he couldn’t be barred for speaking to the media after meeting Sallay, currently held under PTA, or for authoring a book on the 2019 Easter Sunday carnage. According to Gammanpila as long as the suspect had no objections to his lawyer sharing some information with the media it shouldn’t be an issue for Additional Solicitor General Dileepa Peiris.

Police seek Interpol help to probe monks nabbed with narcotics at BIA
Police investigating the thwarted a bid made by 22 Buddhist monks to smuggle in narcotics, with a street value of Rs 660 mn via BIA, from Thailand, over the weekend, believe the monks who organised the clandestine operation had sent groups of monks to Thailand before.
Sources said that they had brought in narcotics on earlier occasions.
Police have seized the mobile phones used by the suspects and sought INTERPOL assistance.
Earlier, the Negombo Magistrate’s Court remanded those 22 monks, arrested in connection with the largest drug bust in the airport’s history.
The monks were produced before the Negombo Magistrate’s Court and ordered to be held in custody until 02 May, as investigations continue into the alleged smuggling operation and any wider networks involved.
However, other sources said that more than 110 kilogrammes of suspected Kush and Hashish, with an estimated street value exceeding Rs 1.1 billion, had been found, concealed in false-bottoms of their suitcases. The bags reportedly packed with school supplies and sweets are said to have contained over five kilogrammes of narcotics per individual.
The arrests followed a raid by the Police Narcotics Bureau on Saturday night. Investigators have also recovered mobile phone evidence indicating that the group had travelled to Bangkok on 22 April using airline tickets allegedly given by a sponsor. Authorities allege that the suspects were photographed in civilian clothing, while overseas, engaging in activities deemed suspicious.
Police say this marks the first reported instance of a large-scale narcotics operation via the airport involving Buddhist monks. The suspects are young monks from different parts of the country.
