- He spearheaded an Indian tribal mass movement that arose in the Bihar and Jharkhand belts in the early 19th century under British colonisation.
- Munda rallied the tribals to fight against the forceful land grabbing carried out by the British government, which would turn the tribals into bonded labourers and force them to abject poverty.
- He influenced his people to realise the importance of owning their land and asserting their rights over it.
- As a reaction to the introduction of the Zamindari system, or Permanent settlement in tribal areas, Birsa Munda in 1894 declared “Ulgulan”, or revolt, against the British and the Dikus – the outsiders.
- He created a faith called ‘Birsait’.
- Known as 'Dharti Abba' or the Earth Father, Birsa Munda stressed the need for the tribals to study their own religion and not forget their cultural roots.

Aurora
Subject: International Relations
Why in News?
Recently, NASA recently shared an incredible picture of an aurora captured from the International Space Station.
Background:-
- The National Aeronautics and Space Administration (NASA) on Tuesday shared a remarkably beautiful image of an aurora taken from the International Space Station as it flew above the American state of Utah.
About Aurora:-
- Auroras are a space weather phenomenon that occurs when electrically charged electrons and protons collide with neutral atoms in the upper atmosphere.
- An Aurora is a display of light in the sky predominantly seen in the high-latitude regions (Arctic and Antarctic).
- It is also known as a Polar light.
- In the Northern Hemisphere, the phenomenon is called the northern lights (aurora borealis), while in the Southern Hemisphere; it’s called the southern lights (aurora australis).
- Auroras result from emissions of photons in the Earth’s upper atmosphere (above 80 km), from ionized nitrogen atoms regaining an electron, and from electrons from oxygen and nitrogen atoms returning from an excited state to the ground state.
- The solar wind coming from the sun is the origin of the charged protons and electrons that excite oxygen and nitrogen and cause auroras.
- The aurora’s colour depends on the type of atom that is excited and how its electrons return from those excited states to the ground state.
- High-energy electrons cause oxygen to emit green light (the most familiar colour of the aurora), while low-energy electrons cause red light.
- Nitrogen generally gives off a blue light.
- The blending of these colours can also lead to purples, pinks, and whites.
- The oxygen and nitrogen also emit ultraviolet light, which can be detected by special cameras on satellites.
- Auroras are not just something that happens on Earth.
- If a planet has an atmosphere and magnetic field, they probably have auroras.
- Discrete Auroras on Mars: Unlike auroras on Earth, which are seen only near the north and south poles, Discrete Auroras (DA) on Mars are seen all around the planet at night time.
- Auroras have been observed on Saturn and Jupiter.

Question for UPSC Daily Current Affairs- 14th November 2023
Try yourself:
What is the main cause of auroras?Explanation
- Auroras are caused by the solar wind, which consists of charged protons and electrons.
- When the solar wind reaches the Earth's upper atmosphere, it interacts with oxygen and nitrogen atoms.
- The charged protons and electrons from the solar wind excite these atoms, causing them to emit light.
- The color of the aurora depends on the type of atom that is excited and how its electrons return to the ground state.
- Therefore, the main cause of auroras is the solar wind originating from the sun.

Euclid Space Telescope unveils mysteries of Dark Universe
Subject: Science and Technology
Why in News?
European astronomers have unveiled the first images captured by the newly launched Euclid space telescope.
- These groundbreaking images offer a glimpse into Euclid’s extraordinary capabilities, demonstrating its capacity to observe billions of galaxies situated up to 10 billion light years away.
What is Euclid Mission?
- Euclid’s mission, led by the European Space Agency (ESA) in partnership with NASA, aims to unravel the enigmatic forces of dark matter and dark energy, which together constitute 95% of the universe.
- The Euclid Space Telescope is equipped with a 1.2-meter primary mirror, allowing it to capture detailed observations of galaxies.
- It carries two main scientific instruments: the visible-wavelength camera (VIS) and the near-infrared camera and spectrometer (NISP).
- By mapping the distribution and evolution of galaxies, Euclid aims to shed light on the fundamental forces shaping the cosmos.
(1) Mission Scope and Duration
- Euclid is a space-based mission, equipped with a sophisticated telescope and state-of-the-art scientific instruments.
- The mission is expected to have a nominal operational lifetime of 6 years, during which it will conduct an extensive survey of the sky.
(2) Launch and Spacecraft
- Euclid was launched on July 1, 2023, from Cape Canaveral in Florida using a SpaceX Falcon 9 rocket.
- The spacecraft carries the Euclid Space Telescope, which is designed to observe galaxies across a wide range of wavelengths.
(3) Investigating Dark Energy and Dark Matter
- Dark energy, discovered in 1998, explains the unexpected acceleration of the universe’s expansion.
- Euclid’s mission aims to provide a more precise measurement of this acceleration, potentially uncovering variations throughout cosmic history.
- Dark matter, inferred through the gravitational effects it exerts on galaxies and clusters, plays a vital role in preserving their integrity.
Unraveling the Dark Universe
- 5% Visible, 95% Dark: The mission emphasizes that our understanding of the universe is limited to merely 5%—the matter we can see. The rest of the universe remains “dark” because it does not emit electromagnetic radiation, but its effects on visible matter are evident.
- Dark Matter’s Role: Dark matter is suspected to influence galaxies’ rotation, galaxy clusters’ cohesion, and the formation of cosmic structures, further validating its existence.
- Dark Energy’s Mystery: Dark energy, an even more enigmatic force, was proposed in the 1990s when the universe’s accelerated expansion was discovered. This mysterious energy was awarded a Nobel Prize in 2011.
Mission Ahead
- Creating a 3D Map: Following its initial commissioning and overcoming technical challenges, Euclid will construct a 3D map covering approximately one-third of the sky. This map will reveal subtle variations attributable to the dark universe.
- Cosmic Web Exploration: By gaining insights into dark energy and dark matter, scientists aim to understand the formation and distribution of galaxies within the cosmic web, a network of cosmic structures that make up the universe.

Inflation
Subject: Economy
Why in News?
The Retail inflation eased to 4.87% in October 2023 compared to 5.02 % in September 2023.
Background:-
- Retail inflation, based on the Consumer Price Index (CPI), eased to 4.87 per cent in October compared to 5.02 per cent in September this year.
About Inflation:-
- Inflation refers to a sustained increase in the general price level of goods and services in an economy over a period of time.
- It is the rise in the prices of most goods and services of daily or common use, such as food, clothing, housing, recreation, transport, consumer staples, etc.
- Inflation measures the average price change in a basket of commodities and services over time.
- The opposite and rare fall in the price index of this basket of items is called ‘deflation’.
- Inflation is indicative of the decrease in the purchasing power of a unit of a country’s currency.
- This is measured in percentage.
Measures of Inflation in India:-
- In India, the Ministry of Statistics and Programme Implementation measures inflation.
- There are two main sets of inflation indices for measuring price level changes in India
- the Wholesale Price Index (WPI) and the Consumer Price Index (CPI).
- GDP deflator is also used to measure inflation.
Impacts of inflation:-
- Reduces people’s purchasing power
- Reduces overall demand
- Harms savers and helps borrowers
- Helps the government meet debt obligations: In the short term, the government, which is the single largest borrower in the economy, benefits from high inflation.
- In the short term, corporates, especially the large and dominant ones, could enjoy higher profitability because they might be in a position to pass on the prices to consumers.
- Worsens the exchange rate.
