Prelims level: Saturn’s Rings
Why in the News?
A new study has challenged previous assumptions, suggesting that Saturn’s rings could be as old as the Solar System (~4.5 billion years old).
About Saturn and Its Rings
- Saturn, the sixth planet from the Sun, is famous for its iconic ring system, made up of billions of ice and rock particles ranging in size from tiny grains to massive chunks.
- It is primarily composed of water ice (95%), with some dust and rocky debris.
- The rings are divided into seven main sections (A to G), with gaps like the Cassini Division.
- Scientists have debated whether the rings formed with Saturn (~4.5 billion years ago) or if they are only 100-400 million years old.
- Over time, tiny space rocks should darken the rings, yet they remain surprisingly bright.
Key Findings of the Study:
- Earlier estimates, based on Cassini data, suggested the rings were 100-400 million years old because they looked clean and bright.
- The new study suggests that micrometeoroid collisions remove dust efficiently, preventing the rings from darkening over time.
- High-speed micrometeoroid impacts (~108,000 km/h) cause dust to vaporize, rather than accumulate.
- The vaporized dust either escapes Saturn’s gravity, falls into the planet’s atmosphere, or gets ejected into space, keeping the rings pristine.
- 100 million years ago, the Solar System was stable, making ring formation unlikely.
- 4 billion years ago, the Solar System was chaotic, increasing the chances of violent planetary collisions that could have formed Saturn’s rings.
Various Missions to Saturn
Saturn has been explored by multiple spacecraft, each providing valuable insights into its rings, atmosphere, and moons.
1. Pioneer 11 (1979)
- First spacecraft to fly past Saturn, capturing basic images.
2. Voyager 1 & Voyager 2 (1980-1981)
- Discovered new moons and ring structures.
- Provided detailed images of Saturn’s rings.
3. Cassini-Huygens (1997-2017)
- A NASA-ESA-ASI mission that orbited Saturn for 13 years.
- Key discoveries:
-
- Confirmed liquid oceans on Enceladus.
- Found methane lakes on Titan.
- Observed Saturn’s rings losing material into the planet’s atmosphere.

Prelims level: Iron Age; Important Sites
Why in the News?
Tamil Nadu CM recently proclaimed that the Iron Age began on Tamil soil over 5,300 years ago (4th millennium BCE), based on findings from Mayiladumparai, Sivagalai, Adichanallur, and Kilnamandi.
Iron Age in India
- The Iron Age in India was initially thought to have begun around 700-600 BCE.
- Radiocarbon dating pushed the timeline back to 1800 BCE, with evidence of iron smelting found in Central Ganga Plain and Eastern Vindhyas.
- Recent discoveries in Tamil Nadu suggest that iron metallurgy was established in South India as early as 3300 BCE.
Notable Iron Age Sites in India:
- Central and Northern India
- Raja Nala-ka-tila (UP): Iron tools and slag found in pre-NBP (Northern Black Polished) deposits (1400–800 BCE).
- Malhar (Chandauli, UP): Furnaces and iron slag indicate a major iron metallurgy center (1200 BCE).
- Dadupur (UP): Large-scale iron smelting evidence dating back to 1000 BCE.
- Hastinapur (UP): Iron tools associated with the Painted Grey Ware (PGW) culture (1000 BCE).
- Takshashila (Punjab, Pakistan): Iron tools found in Gandhara settlements (800 BCE).
- Western and Central India
- Ahar (Rajasthan): Chalcolithic culture (2500–1700 BCE) showed early evidence of iron artifacts.
- Naikund (Vidarbha, Maharashtra): Discovery of an iron smelting furnace (1000 BCE).
- Mahurjhari (Nagpur, Maharashtra): Horse ornaments made of copper with iron knobs (800 BCE).
- South India
- Paiyampalli (Tamil Nadu): Large-scale iron smelting and slag deposits (1200 BCE).
- Adichanallur (Tamil Nadu): Iron tools and burial urns linked to Megalithic culture (1000 BCE).
- Mayiladumparai (Tamil Nadu): Recent findings date iron usage to 3300 BCE, making it one of the oldest sites of iron metallurgy in India.
- Sivagalai (Tamil Nadu): Iron artifacts and slag deposits, indicating early smelting practices (1100 BCE).
Iron Age in Tamil Nadu: New Discoveries
- Earlier studies in Mayiladumparai Excavation (2022) suggested that the Iron Age began 4,200 years ago (3rd millennium BCE).
- This timeline coincides with the Copper/Bronze Age in North India, indicating a technological divergence between the regions.
- The latest State Archaeology Department’s report, “Antiquity of Iron: Recent Radiometric Dates from Tamil Nadu”, confirms that Iron smelting began as early as 3,345 BCE – 2,953 BCE.
- Limited availability of copper ores in South India might have led to the early adoption of iron technology.
- Excavations in Sivagalai, Adichanallur, Kilnamandi, and Mayiladumparai indicate that the Iron Age in Tamil Nadu predates much of North India.

From UPSC perspective, the following things are important :
Prelims level: Polarized Moonlight
Why in the News?
Scientists at Macquarie University, Sydney, have discovered that two species of nocturnal bull ants (Myrmecia pyriformis and Myrmecia midas) rely on polarised moonlight for navigation.
What is Polarised Moonlight?
- Polarised moonlight refers to moonlight that has undergone scattering in Earth’s atmosphere, causing its waves to oscillate in a specific direction.
- Unlike direct moonlight, which is unpolarised, the light that scatters in the sky becomes linearly polarised, meaning its electric field aligns in a fixed plane.
- The moon emits unpolarised light, but when it interacts with air molecules and dust particles in the atmosphere, it scatters and becomes polarised.
- The intensity of polarised moonlight is much lower than polarised sunlight, making it harder for most animals to detect.
- The pattern of polarisation in moonlight remains stable, allowing nocturnal animals to use it as a reliable navigation tool.
- Why is it Important for Navigation?
- Many nocturnal animals, including bull ants (Myrmecia pyriformis and Myrmecia midas), rely on celestial cues to orient themselves.
- Unlike the moon’s direct position, which changes with phases and cloud cover, the polarisation pattern remains detectable throughout the night.
- This enables ants to navigate effectively even under crescent or waning moons, where light intensity is significantly lower.
E-Vector Pattern and Ant Navigation
- Polarised moonlight forms a distinct pattern in the sky, known as the E-vector pattern.
- This pattern shifts based on the moon’s position, but its orientation remains stable, allowing insects like ants to use it as a natural compass.
- The E-vector pattern aligns at 90° to the moon’s direct light, creating a predictable navigation reference.
- How do Bull Ants use it?
- Ants detect the E-vector pattern in the night sky using their specialised compound eyes, which are sensitive to polarised light.
- Even in dim conditions, they adjust their movements according to the orientation of polarised moonlight.
- Researchers found that when the E-vector was artificially rotated, the ants changed their paths accordingly, confirming that they rely on this pattern.
- When the moonlight disappeared (during a new moon phase), the ants struggled to navigate, further proving their dependence on polarised lunar light.

Prelims level: Delhi Earthquake and its causes
Why in the News?
A magnitude 4 earthquake struck New Delhi with epicentre near Dhaula Kuan. The quake was shallow (5 km depth), highlighting Delhi’s seismic vulnerability due to its location in Zone IV of India’s earthquake hazard map.
Possible Causes of the Earthquake
- Tectonic Activity along the Delhi-Hardwar Ridge:
- Delhi sits on the Delhi-Hardwar Ridge, an active seismic fault.
- Continuous collision of the Indian and Eurasian plates builds tectonic stress, leading to earthquakes when stress is released.
- Groundwater Extraction as a Seismic Trigger: Excessive exploitation alters rock pressure, potentially inducing fault movements.
- Anthropogenic (Human-Induced) Activity:
- Urbanization, metro construction, and large-scale infrastructure projects alter subsurface stress.
- Vibrations from construction activities can contribute to localized seismic instability.
About the Aravalli-Delhi Fold Belt
- The Aravalli-Delhi Fold Belt is a major geological formation that extends from southern Rajasthan to Haryana and Delhi.
- It consists of ancient folded rock formations that have undergone millions of years of geological transformation.
- This region has several pre-existing faults, meaning seismic activity can occur without direct tectonic subduction.
- Although historically more active, tectonic movements in the belt have slowed over time.
- These earthquakes occur due to fault reactivation and local stress accumulation rather than large-scale tectonic shifts.
- Himalayan earthquakes are caused by subduction, where the Indian plate moves under the Eurasian plate.
PYQ:
[2021] Discuss about the vulnerability of India to earthquake related hazards. Give examples including the salient features of major disasters caused by earthquakes in different parts of India during the last three decades.

Why in the News?
The Haryana government has proposed an ambitious 3,858-hectare Aravalli Safari Park spread across Gurugram and Nuh, which aims to be the world’s largest safari park.
About the Aravalli Range
- The Aravalli Range is one of the oldest fold mountain ranges in the world, dating back to the Proterozoic era.
- It stretches 692 km from Gujarat to Delhi, passing through Rajasthan and Haryana.
- The range acts as a natural green barrier, preventing the expansion of the Thar Desert into eastern Rajasthan and the Gangetic plains.
- Highest Peak: Guru Shikhar (1,722 meters) in Mount Abu, Rajasthan.
- Rivers originating from the Aravalli Range:
- Banas and Sahibi Rivers (tributaries of the Yamuna).
- Luni River, which flows into the Rann of Kutch.
- Rich in mineral resources, including copper, zinc, lead, and marble.
- The Aravalli hills play a critical role in groundwater recharge, acting as natural aquifers.
- 80% of the range is in Rajasthan, while the rest is in Haryana, Delhi, and Gujarat.
|
What is the Aravalli Safari Park Project?
- The Haryana government has proposed a 3,858-hectare Aravalli Safari Park, intended to be the world’s largest.
- The project covers 2,574 hectares in Gurugram and 1,284 hectares in Nuh.
- It will include animal enclosures, botanical gardens, aquariums, cable cars, hotels, and an animal hospital.

From UPSC perspective, the following things are important :
Prelims level: mRNA (Messenger RNA)
Why in the News?
In December 2024, Russia announced the development of a new mRNA-based personalized cancer vaccine, with plans to make it available for free to patients by early 2025.
What is mRNA (Messenger RNA)?
- mRNA is a type of RNA that transports genetic information from DNA to ribosomes, guiding the production of proteins.
- It tells the cell which proteins to make by providing the exact sequence of amino acids.
- Unlike DNA, mRNA does not stay in the cell permanently; it gets degraded after protein synthesis.
- mRNA-based vaccines (like COVID-19 vaccines) teach cells to produce harmless viral proteins, triggering an immune response.
|
What is an mRNA Cancer Vaccine?
- Unlike traditional vaccines, mRNA vaccines provide genetic instructions to train the immune system to detect and attack cancer cells.
- This technology gained prominence with the COVID-19 vaccines (Pfizer-BioNTech, Moderna) and is now being adapted for cancer treatment.
- These vaccines are therapeutic, designed for patients who already have cancer, not for prevention.
How do mRNA Cancer Vaccines Work?
- Cancer cells evade the immune system by suppressing immune responses.
- Immunotherapy works by enhancing the body’s natural ability to detect and destroy these cancerous cells.
- Unlike chemotherapy, which kills both healthy and cancerous cells, immunotherapy selectively targets only cancer cells, reducing harmful side effects.
- mRNA cancer vaccines are customized for each patient, targeting specific tumor antigens, making them highly personalized and potentially more effective.
- While traditional infectious disease vaccines prevent illness, mRNA cancer vaccines are therapeutic, meaning they are administered to patients who already have cancer to help their immune system fight the disease.
PYQ:
[2019] RNA interference (RNAi)’ technology has gained popularity in the last few years. Why?
- It is used in developing gene silencing therapies.
- It can be used in developing therapies for the treatment of cancer.
