Einstein Ring Discovered by ESA’s Euclid Telescope
- 15 Feb 2025
In News:
- The European Space Agency’s (ESA) Euclid space telescope has recently discovered a rare Einstein ring around the galaxy NGC 6505, located nearly 590 million light-years from Earth.
- This ring was formed by the light of a distant unnamed galaxy situated 4.42 billion light-years away, distorted and amplified due to gravitational lensing by NGC 6505.
What is an Einstein Ring?
- It is a circular ring of light that appears around a massive celestial object such as a galaxy, dark matter concentration, or cluster of galaxies.
- Caused due to strong gravitational lensing, it occurs when a massive foreground object (gravitational lens) bends and amplifies the light from a background object, resulting in a circular or arc-like appearance.
- The phenomenon only results in a full ring when the observer, lensing object, and background galaxy are almost perfectly aligned.
Theoretical Basis
- Named after Albert Einstein, who in his General Theory of Relativity predicted that massive objects warp space-time, thereby bending the path of light.
- The phenomenon of gravitational lensing, and by extension Einstein rings, was first theoretically anticipated by Einstein and empirically confirmed much later.
Scientific Importance
- Extremely rare phenomena: Occur in less than 1% of galaxies.
- Serve as natural cosmic magnifying lenses that allow scientists to study:
- Dark Matter: Helps trace the invisible distribution of dark matter through gravitational effects.
- Dark Energy: Supports understanding of dark energy’s role in accelerating the universe’s expansion.
- Distant Galaxies: Reveals otherwise invisible galaxies by amplifying their light.
- Universe Expansion: Provides data on how space between galaxies stretches over cosmic time.
Gravitational Lensing: Explained
- Gravitational lensing occurs when a massive body (galaxy, cluster, black hole) creates a gravitational field that bends and magnifies light from objects behind it.
- This leads to multiple outcomes — arcs, double images, or full rings (Einstein rings).
- The lensing object in the recent case is NGC 6505, a galaxy first observed in the 19th century.
Observation and Imaging
- Einstein rings are not visible to the naked eye and require powerful space telescopes like Euclid for detection.
- Euclid captured images showing a bright central galaxy (NGC 6505) with a distinctive, cloudy ring formed by the bent light from the background galaxy.
About the Euclid Space Telescope
- Launched in 2023 by ESA using a SpaceX Falcon 9 rocket from Cape Canaveral, Florida.
- Operates from Lagrangian Point 2 (L2), located 1.5 million km from Earth.
- Designed for a six-year mission to study the dark universe.
- Key Objectives:
- Create the largest 3D map of the cosmos.
- Observe billions of galaxies across 10 billion light-years.
- Understand the distribution of dark matter and the influence of dark energy in the early universe.
- Study light emitted from galaxies up to 10 billion years ago to trace cosmic evolution.

- Part C: Gender-neutral budgets that may require gender-sensitive planning (e.g., Har GharNal project, which reduces women’s time spent fetching water).
- Policy Vision and Challenges:
- The Union Budget for 2025-26 is part of the government’s vision for a "Viksit Bharat" with zero poverty, universal education, 100% skilled labor, and 70% female participation in the workforce by 2047.
- While the Budget lays a strong foundation, addressing persistent challenges like gender pay gaps, occupational segregation, and cultural barriers will require sustained policy interventions, gender-sensitive workplace reforms, and effective implementation of gender-disaggregated data for monitoring outcomes.
Corruption Perceptions Index (CPI) 2024

- 15 Feb 2025
In News:
India ranked 96th out of 180 countries in the Corruption Perceptions Index (CPI) for 2024, with a score of 38, a decline from 39 in 2023 and 40 in 2022. This indicates a worsening perception of corruption within India’s public sector.
Global Context:
- The CPI, compiled annually by Transparency International, is a widely recognized global ranking system that evaluates the perceived levels of corruption in public sectors.
- It uses a scale of 0 to 100, where 0 indicates highly corrupt and 100 signifies very clean.
- The CPI is based on expert assessments and surveys, drawing from at least three data sources out of 13 recognized corruption assessments from organizations like the World Bank and the World Economic Forum.
- Top Ranking Countries: Denmark topped the 2024 CPI, followed by Finland and Singapore, indicating strong governance systems with minimal corruption. These countries are recognized for their effective public sector governance, transparency, and low corruption levels.
- Regional Comparison: Among India’s neighbors, Pakistan ranked 135th, Sri Lanka at 121st, Bangladesh at 149th, and China ranked 76th, performing relatively better than India. The Asia-Pacific region, in general, saw a decline in its average CPI score, dropping by one point to 44.
- Global Trends: The CPI 2024 reveals troubling global trends, with corruption being a persistent issue worldwide. While 32 countries have significantly improved their corruption scores since 2012, 148 countries have either stagnated or worsened in the same period.
- The global average score remains at 43, with more than two-thirds of countries scoring below 50, signaling a widespread corruption problem.
- Corruption’s Impact on Climate Action: One of the significant findings in 2024 is the link between corruption and climate action. Corruption undermines efforts to combat climate change by misappropriating funds meant for emission reduction and climate adaptation projects.
- The report warns that such corruption obstructs effective policies and hinders climate change mitigation, leading to environmental degradation. Furthermore, it highlights that corruption in high-CPI countries often serves the interests of fossil fuel companies, complicating global climate efforts.
- Corruption and Human Rights: The report underscores that corruption not only impedes economic development but also contributes to the erosion of democracy, human rights violations, and instability. Corruption, particularly in the form of misallocation of resources, exacerbates the vulnerability of populations already affected by climate change, poverty, and human rights abuses.
- Financial Hubs and Illicit Funds: Many countries with high CPI scores, despite their lower domestic corruption levels, serve as financial hubs that attract illicit funds stemming from corruption and environmental damage. This "dirty money" exacerbates corruption on a global scale and has far-reaching consequences that extend beyond national borders.
- The Call for Action: Transparency International’s report stresses the need for global cooperation in tackling corruption. It warns that corruption is a major contributor to the rise of authoritarianism and calls for urgent, concrete action to address global corruption. The report emphasizes that combating corruption is crucial for achieving a peaceful, sustainable, and democratic world.
