Current Affairs Quiz - May 2025

Notes:
Amazon has launched the first 27 satellites under its Project Kuiper to build an internet-from-space network. Project Kuiper is Amazon’s satellite broadband initiative using Low Earth Orbit (LEO), which is up to 2,000 kilometers above Earth. It includes around 3,232 satellites, ground stations, and customer terminals to provide the service. The goal is to deliver high-speed, low-latency, and affordable internet to remote and underserved regions globally. The project is named after the Kuiper Belt, a distant region of the solar system beyond the eight planets. It is Amazon’s answer to SpaceX’s Starlink satellite internet system.

Notes:
Researchers at the Institute of Nano Science and Technology (INST), Mohali, have found a new way to improve green hydrogen production. They created a special heterostructure using Copper Tungsten Oxide and Copper Oxide. This structure uses the Built-In Electric Field (BIEF) effect to boost the Hydrogen Evolution Reaction (HER). The Copper Tungsten Oxide nanoparticles are grown over a Cu(OH)₂ base, forming a p-n heterojunction with an uneven electronic setup. This BIEF helps in better proton adsorption and desorption. Green hydrogen, made from water using clean energy, is a pollution-free fuel of the future.

Notes:
The National AYUSH Mission (NAM) Conference 2025 takes place on May 1-2 at Kaivalyadhama in Lonavala, Maharashtra. The event is organized by the Ministry of Ayush to strengthen the integration of traditional Indian medicine systems into mainstream healthcare. The conclave aims to foster a collaborative ecosystem, discuss latest developments, research innovations, and sectoral collaborations across various AYUSH systems.

Notes:
The government has revamped the National Security Advisory Board (NSAB) after the Pahalgam terror attack, appointing former intelligence chief Alok Joshi as chairman. National Security Advisory Board (NSAB) is an advisory body under the National Security Council (NSC) structure. It is chaired by the Prime Minister, supported by the National Security Advisor (NSA) and the National Security Council Secretariat (NSCS). Established in 1998 after the Pokhran-II nuclear tests, it institutionalized India’s national security framework. The NSAB provides non-partisan strategic inputs on national security issues but is not a decision-making body. It reports to the NSCS and includes experts from various sectors.

Notes:
The European Red Admiral butterfly, scientifically called Vanessa atalanta, has been recorded for the first time in India near Dharamshala, Himachal Pradesh. This rare sighting was confirmed during a butterfly survey at Thatharna Hill in the Dhauladhar mountain range, at an altitude of 2,500 metres. The observation was verified by Himalayan butterfly expert Lovish Garlani from the Himachal Pradesh Forest Department. This raises the total number of butterfly species in Himachal Pradesh to 440, highlighting the region’s rich biodiversity. The species is known for long migrations across Europe and North America and was last seen in South Asia in 2022 in Pakistan after a 93-year gap. It has no confirmed records from China, Mongolia, or Afghanistan, making its presence in India a significant eastward range expansion.

Notes:
Operation Kagar has successfully encircled the last remaining Naxal strongholds in the Chhattisgarh-Telangana border regions. Operation Kagar was launched by the Ministry of Home Affairs to eliminate Maoist insurgents and dismantle the political ideology of Maoism. The operation combines military action, surveillance technology, and development outreach to combat Left-Wing Extremism (LWE). The campaign has reduced Naxal-affected districts from 106 in 2015 to just 6 in 2025. In 2024, 287 Naxals were neutralized, with over 150 already in 2025.

Notes:
Reliance NU Suntech recently signed a 25-year Power Purchase Agreement with the Solar Energy Corporation of India Limited (SECI) to build Asia’s largest single-location integrated solar and Battery Energy Storage System (BESS) project. SECI is a Central Public Sector Undertaking (CPSU) under the Ministry of New and Renewable Energy (MNRE), dedicated to expanding Renewable Energy (RE) in India. SECI was formed in 2011 as a not-for-profit company and later became a commercial entity in 2015. It was established to support the National Solar Mission and has Miniratna Category-I status. SECI acts as the main agency for implementing solar, wind, and hybrid energy projects across India. It also helps fulfill India’s Nationally Determined Contributions (NDCs) by inviting developers through tenders for RE projects.

Notes:
Recently, scientists observed repeated unrest at Campi Flegrei between 1982–1984 and 2011–2024, involving land uplift, earthquakes, and underground rumbling due to rising fluid pressure. Campi Flegrei, also called the Phlegraean Fields, is an active volcanic system located near Naples, Italy. Unlike single-cone volcanoes like Mount Vesuvius, Campi Flegrei is a large caldera, which is a sunken volcanic area formed after a huge eruption. The caldera spans about 12 to 15 kilometers and was formed by a massive eruption nearly 39,000 years ago. That eruption may have triggered climate changes that contributed to the decline of Neanderthals.

Notes:
Scientists are closely watching the Axial Seamount as it is expected to erupt for the first time in ten years. Axial Seamount is an underwater shield volcano located about 300 miles off the coast of Oregon, United States, in the Pacific Ocean. It has a large caldera at its summit and rises to a depth of 1,400 meters below sea level. The volcano was formed by a hot spot, where molten material from Earth’s mantle rises into the crust. It lies on the Juan de Fuca Ridge, the tectonic boundary between the Pacific and Juan de Fuca plates. It features hydrothermal vents, which are underwater hot springs that release mineral-rich plumes heated by magma.

Notes:
Scientists from the University of Oxford have suggested a new way to monitor volcanic eruptions using a method called shear-wave splitting. Shear-wave splitting happens when seismic waves travel at different speeds depending on their direction, especially through rocks with tiny cracks. This technique was studied at Mount Ontake in Japan, which is an active stratovolcano located on Honshū Island, near Tokyo. Mount Ontake is Japan’s second-highest volcano and lies in the Pacific Ring of Fire.
