In a groundbreaking study that delves into one of the enduring mysteries of space, scientists have utilized data from NASA’s retired Kepler Space Telescope to uncover evidence explaining why certain exoplanets are shrinking in size. Led by Caltech/IPAC scientist Jessie Christiansen, the research suggests a fascinating link between the cores of specific sub-Neptune planets and the reduction of their atmospheres. Exoplanets, planetary bodies discovered beyond our solar system, number over 5000 so far. However, astronomers have long observed a peculiar “size gap” between rocky super-Earths and gaseous sub-Neptunes, with a scarcity of planets having diameters between 1.5 and 2 times that of Earth. Published in The Astronomical Journal, the study proposes that atmospheric loss in less massive sub-Neptunes could be the key factor behind this size gap. Jessie Christiansen explains, “Our findings indicate there’s a significant factor preventing these planets from maintaining or achieving this size.” The research introduces two primary mechanisms driving atmospheric loss: core-powered mass loss and photoevaporation. The evidence strongly supports core-powered mass loss, where radiation from a planet’s hot core gradually forces the atmosphere outwards. Photoevaporation, akin to a hairdryer melting an ice cube, occurs when a star’s intense radiation strips away a planet’s atmosphere. While this process is believed to transpire within the first 100 million years of a planet’s existence, core-powered mass loss likely occurs around the 1 billion-year mark. To substantiate their theories, the research team scrutinized data from the K2 mission, concentrating on the young star clusters Praesepe and Hyades. The findings revealed that nearly all stars in these clusters still harbor sub-Neptune planets, indicating that their atmospheres have not been eroded by photoevaporation. This observation strongly supports core-powered mass loss as the more plausible explanation for the observed size gap. The implications of this study extend beyond solving a cosmic puzzle; they provide insights into the evolution of exoplanet atmospheres, offering potential clues about the habitability of distant worlds. As Christiansen notes, ongoing research and future studies will continue to test and refine these theories, unlocking further mysteries of the universe.

India Requests Evidence from Canada on Nijjar Killing Allegation: Investigation Not Ruled Out11/16/2023 In a recent development, India has formally requested Canada to provide evidence substantiating allegations of Indian agents’ involvement in the killing of terrorist Hardeep Singh Nijjar on June 18 in British Columbia. External Affairs Minister S Jaishankar has stated that India remains open to an investigation into the matter, highlighting the need for responsible sharing of information. During a conversation with a journalist, External Affairs Minister S Jaishankar emphasized that the request for evidence is grounded in the context of concerns regarding the accommodation of individuals espousing violent and extreme political opinions in Canadian politics. These opinions often advocate separatism from India through violent means. Jaishankar shed light on the challenging diplomatic circumstances, citing instances where Indian diplomats, including the High Commissioner, faced attacks and intimidation in Canada. He underscored the importance of freedom of speech and expression, emphasizing that these freedoms come with a responsibility that should not be misused for political purposes. Addressing the lack of evidence shared by Canada to support its allegations, Jaishankar stated, “If you have a reason to make such an allegation, please share the evidence with us. We are not ruling out an investigation and are willing to consider any information they may have, but they haven’t done so.” The strained relations between India and Canada arose after Canadian Prime Minister Justin Trudeau made allegations in September about the potential involvement of Indian agents in Nijjar’s killing. India had designated Nijjar as a terrorist in 2020. The Indian government dismissed Trudeau’s claims as “absurd” and “motivated,” leading to the temporary suspension of visa issuance to Canadian citizens and a request for Ottawa to downsize its diplomatic presence. As the dialogue between the two nations continues, India’s stance reflects a commitment to a thorough and objective examination of the situation, with the expectation that any serious allegations should be supported by credible evidence. In a recent development, the Indian Space Research Organisation (Isro) has reported the successful completion of an uncontrolled re-entry into Earth’s atmosphere for the cryogenic upper stage of the LVM3 M4 launch vehicle. This component played a vital role in propelling the Chandrayaan-3 spacecraft into its designated orbit on July 14, 2023. The unplanned descent occurred at approximately 14:42 IST on Wednesday, marking a noteworthy event within 124 days post-launch. The rocket body, an integral part of Isro’s lunar exploration initiative, adhered to the “25-year rule” established by the Inter-Agency Space Debris Coordination Committee (IADC). This rule ensures the responsible disposal of space debris by requiring defunct satellite components to re-enter Earth’s atmosphere within 25 years. Leading up to the re-entry, the upper stage underwent a meticulous process known as “passivation.” This method involves the elimination of residual propellants and potential energy sources, significantly reducing the risk of accidental explosions during the re-entry phase. Isro’s commitment to these measures aligns with the stringent space debris mitigation guidelines outlined by both the United Nations and IADC. Isro’s successful execution of the passivation process and subsequent controlled disposal of the rocket body not only underscores its technical proficiency but also emphasizes its dedication to maintaining the long-term sustainability of outer space activities. By adhering to internationally recognized standards, Isro reinforces its role as a responsible participant in the global space community. The Chandrayaan-3 mission, featuring a lander and rover configuration, stands as a testament to India’s advancements in safe lunar landing and exploration. The mission’s triumph, coupled with the conscientious disposal of the launch vehicle’s upper stage, represents a dual achievement for Isro. It not only showcases India’s growing expertise in space exploration but also underscores its commitment to environmental stewardship in the realm of space exploration. Virat Kohli Surpasses Sachin Tendulkar’s 25-Year Century Record in World Cup 2023 Semi-Final11/15/2023 In a historic turn of events on Wednesday, November 15, Virat Kohli emerged as the new leading century-maker in ODIs, toppling Sachin Tendulkar’s 25-year reign. The 35-year-old cricket maestro achieved this milestone by notching up his 50th ODI hundred during the 2023 World Cup semi-final clash against New Zealand at Mumbai’s iconic Wankhede Stadium. This significant shift in cricket history harks back to September 26, 1998, when Tendulkar, often hailed as the Master Blaster, secured his 18th ODI century against Zimbabwe at Queens Sports Club in Bulawayo. His unbeaten 127 off 130 balls led India to a resounding victory by eight wickets, chasing down a target of 214 in 42.2 overs. With that century, Tendulkar overtook West Indies legend Desmond Haynes, who previously held the record with 17 ODI centuries. Tendulkar’s record-setting innings kept him at the helm for an impressive 9181 days before Kohli stepped into the limelight on Wednesday. Kohli had previously equaled Tendulkar’s century tally during the India vs. South Africa clash at Eden Gardens in Kolkata. Facing New Zealand in the semi-final showdown, Kohli showcased his prowess by scoring 117 runs off 113 balls, adorned with nine fours and two sixes. His century propelled India to a formidable total of 397 for four, ultimately securing a 70-run victory and sealing their spot in the World Cup final scheduled to take place in Ahmedabad on Sunday. In response to Kohli’s monumental achievement, Tendulkar took to Instagram to express his admiration. Reflecting on their first meeting in the Indian dressing room 15 years ago, Tendulkar shared a light-hearted memory of Kohli being pranked into touching his feet by teammates. He praised Kohli’s growth as a player and expressed joy that an Indian cricketer had broken his record. “The first time I met you in the Indian dressing room, you were pranked by other teammates into touching my feet. I couldn’t stop laughing that day. But soon, you touched my heart with your passion and skill. I am so happy that that young boy has grown into a ‘Virat’ player,” Tendulkar wrote on Instagram. “I couldn’t be happier that an Indian broke my record. And to do it on the biggest stage — in the World Cup Semi-Final — and at my home ground is the icing on the cake,” he added Seven engineering students from PSG College of Technology on Avinashi Road in Coimbatore, Tamil Nadu, have been arrested by the police for their alleged involvement in a ragging incident against a junior student. The distressing episode, which took place on Monday, November 6, resulted in the victim, Rubak Varma, a first-year engineering student from Tiruppur, being disrobed and having his head tonsured inside the college hostel. The accused individuals, namely Dharanitharan, Venkatesh, Madhavan, Mani, Ayyappan, Santhosh, and Yalish, were taken into custody. Among them, Dharanitharan and Venkatesh are second-year students, while Madhavan and Mani are in their third year. The rest of the accused are in their final year of engineering studies. According to reports, on Monday evening, the accused students demanded money from Rubak Varma for purchasing liquor. Upon his refusal, they reportedly assaulted him, took him to their room, and allegedly confined him until Tuesday morning. During this time, he was subjected to further physical abuse, including being stripped naked and having his head tonsured with a trimmer. The perpetrators purportedly recorded the entire act on their phones. Following his release, Rubak Varma informed his parents about the harrowing incident, prompting them to rush to Coimbatore and file a complaint with the college administration. Simultaneously, a formal complaint was lodged against the seven accused students at the E2 Peelamedu police station. The police acted swiftly, and on the night of Tuesday, November 7, the accused were arrested based on the filed complaint. The accused students face charges under various sections of the Indian Penal Code, including voluntarily causing hurt, voluntarily causing hurt with a dangerous weapon, wrongful confinement, unlawful assembly, assaults or uses of criminal force, and criminal intimidation. Additionally, they have been booked under Section 4 of the Tamilnadu Ragging Prohibition Act 1997, which stipulates penalties of up to two years of imprisonment and a fine of up to Rs 10,000. This incident highlights the urgent need to address ragging and ensure the safety of students within educational institutions. Hey there, readers!

Total toll crosses 3,000; IDF launches deadly strikes on Gaza, Hamas’ rockets hit Ashkelon Israeli Prime Minister Benjamin Netanyahu on Tuesday dialled Prime Minister Narendra Modi to apprise him of the ground situation in Israel following the brutal attack by Hamas. Modi expressed his deep condolences and sympathy for those killed and wounded in the terrorist attacks and assured Netanyahu of India’s unwavering support to Israel in these difficult times. “I thank Prime Minister @netanyahu for his phone call and providing an update on the ongoing situation,” Modi posted on X, while asserting that India unequivocally condemns terrorism in all forms and manifestations.
According to Israel Defense Forces (IDF), the toll from the terror attack on Israel crossed 1,000 as of Tuesday. Plus, around 1,500 bodies of Hamas fighters were retrieved from Israel around the Gaza Strip, officials said. The toll in Gaza due to Israel’s retaliatory airstrikes is put at 830, taking the total war death count to over 3,000. “We are going to go on the offensive and attack the Hamas terrorist group and any other group that is in Gaza,” said Brig Gen Dan Goldfus while briefing reporters in Jerusalem on Tuesday. The fighting intensified on the fourth day with both Israel and Hamas stepping up their attacks. While Israel continued to bomb select targets in Gaza, the militant outfit fired rockets on the Israeli city of Ashkelon. Notably, Hamas issued prior warning to residents of the city to leave. Israel’s high-intensity air strikes in the densely populated enclave flattened buildings and caused thousands of residents to flee. According to reports, hospitals are overwhelmed as waves of injured Palestinians are brought in for treatment. The IDF said it has killed two top leaders of Hamas — Jawad Abu Shammala and Zakaria Abu Maamar — in an air strike in southern Gaza Strip. However, Hamas is yet to confirm this claim. Meanwhile, in a blow to hopes of an early release of hostages, Hamas said it won’t negotiate until the “end of the battle”. According to initial estimates, the invading militants had taken around 150 people from Israel hostage. Two Palestinian photographers, Nidal Al-Wahidi from the Al-Najah channel and Haitham Abdelwahid from the Ain Media agency, have also been reported missing since Saturday. An Israeli airstrike in Gaza City killed two Palestinian journalists early Tuesday, according to Palestinian news agency Wafa.
Wafa identified the journalists as editor Saeed Al-Taweel and photographer Mohammed Sobih. The airstrike occurred close to an area housing several media offices. Meanwhile, three Palestinian journalists were reportedly shot and killed while reporting in Gaza on Saturday. Committee to Protect Journalists, citing Palestinian press freedom groups, identified two of them as photographer Ibrahim Mohammad Lafi and reporter Mohammad Jarghoun. CPJ also said that reports confirmed that freelance reporter Mohammad El-Salhi was shot dead in the central Gaza Strip. Lafi worked for Ain Media, and Jarghoun reported for Smart Media, CPJ said. In addition, Ibrahim Qanan, a correspondent for Al-Ghad channel, sustained injuries due to shrapnel in the city of Khan Yunis in the southern Gaza Strip, CPJ said, quoting Palestinian press freedom groups. Two Palestinian photographers, Nidal Al-Wahidi from the Al-Najah channel and Haitham Abdelwahid from the Ain Media agency have also been reported missing since Saturday. Israeli Prime Minister Netanyahu on Monday declared that Israel's fierce offensive against Hamas in the Gaza Strip has “only started.” Israel formally declared war on Sunday. The hostilities so far have killed around 900 people in Israel and more than 680 people in Gaza, according to authorities on each side. Israel and Hamas have had repeated conflicts in past years, often sparked by tensions around Al-Aqsa Mosque, a holy site in Jerusalem. This time, the context has become potentially more explosive. |
