Astronomers have recently observed a previously unknown type of supernova, in which a massive star exploded under the gravitational influence of a black hole companion.
About the recent phenomenon
A binary star system, about 700 million light-years away, initially composed of two massive stars, was observed.
One of the stars reached the end of its life, going supernova and collapsing into a black hole.
The surviving companion star, at least 10 times as massive as the Sun, gradually spiraled closer to the black hole.
The black hole distorted the star and pulled away its material. Eventually, the star exploded in a supernova-like event.
India achieved 20% ethanol blending in petrol (E20) in 2025, five years earlier than the 2030 target set under the National Policy on Biofuels (2018).
Way Forward
Diversify Feedstock: Shift away from sugarcane to alternative sources such as maize, bamboo, and agricultural residues to reduce environmental impact.
Consumer Protection: Implement tax incentives or compensation as recommended by NITI Aayog to address concerns over fuel efficiency drop.
Balanced Energy Strategy: Use ethanol as a transitional or bridge fuel while aggressively scaling up EV adoption backed by renewable energy-supported charging infrastructure.
Recently, the Prime Minister of India has unveiled a new vision for India’s Goods and Services Tax (GST) regime aimed at simplifying tax structures benefiting the poor, middle class, entrepreneurs, traders, and business owners.
Suggestions for Future Improvements
Settle classification disputes to reduce litigation;
Correct inverted duty structures, especially in textiles and MSMEs;
Establish GST Appellate Tribunals for faster resolution of disputes;
Enhance digital infrastructure for smoother filing and reconciliation;
On India’s 79th Independence Day, Prime Minister Narendra Modi announced a high-powered demography mission to protect the country from the dangers posed by illegal immigrants.
Illegal immigration in India
It is a multifaceted issue involving unauthorized entry, overstaying of visas, and undocumented migration across porous borders.
India faces challenges from cross-border migration, especially in northeastern states like Assam and West Bengal, leading to concerns over jobs, social stability, and culture.
In India, caste remains a deeply rooted social structure, and ‘honour’ killings are emerging as a violent yet socially legitimised tool to preserve caste hierarchies, especially against inter-caste unions.
About Honour Killings
Definition: Honour killings refer to the murder of individuals (mostly young couples) by family or community members for allegedly bringing “dishonour” through relationships that defy caste, community, or gender norms.
Geographical Pattern: States like Tamil Nadu, Telangana, Maharashtra, and Kerala, where Dalit empowerment through education and jobs is higher, record both higher rates of inter-caste marriages and higher cases of honour killings.
Paradox: Violence is most visible where caste hierarchies are being challenged, not where they remain unchallenged.
According to NCRB (National Crime Records Bureau) data, India recorded 25 cases of honor killings in both 2019 and 2020, with a rise to 33 cases in 2021.
