Prelims level: Bio-ethanol
Mains level: Ethanol blended petrol programme
The government has set targets of 10 per cent bioethanol blending of petrol by 2022 and to raise it to 20 per cent by 2030 to curb carbon emissions and reduce India’s dependence on imported crude oil.

Q.Given below are the names of four energy crops. Which one of them can be cultivated for ethanol?(CSP 2010)
(a) Jatropha
(b) Maize
(c) Pongamia
(d) Sunflower
What is Ethanol Blended Petrol (EBP) Program?
- Ethanol Blended Petrol (EBP) programme was launched in January 2003 for the supply of 5% ethanol blended petrol.
- The programme sought to promote the use of alternative and environment-friendly fuels and to reduce import dependency for energy requirements.
- OMCs are advised to continue according to the priority of ethanol from 1) sugarcane juice/sugar/sugar syrup, 2) B-heavy molasses 3) C-heavy molasses and 4) damaged food grains/other sources.
Bio-ethanol blend in India
- 1G and 2G bioethanol plants are set to play a key role in making bio-ethanol available for blending but face challenges in attracting investments from the private sector.
- 1G bioethanol plants utilise sugarcane juice and molasses, byproducts in the production of sugar, as raw material, while 2G plants utilise surplus biomass and agricultural waste to produce bioethanol.
- Currently, domestic production of bioethanol is not sufficient to meet the demand for bio-ethanol for blending with petrol at Indian Oil Marketing Companies (OMCs).
- Sugar mills, which are the key domestic suppliers of bio-ethanol to OMCs, were only able to supply 1.9 billion litres of bio-ethanol to OMCs equating to 57.6 per cent of the total demand of 3.3 billion litres.
Hurdles in meeting the demand
- Lack of infrastructure: Many sugar mills are best placed to produce bioethanol do not have the financial stability to invest in biofuel plants. There are also concerns among investors on the uncertainty over the price of bio-ethanol in the future.
- Lack of raw materials: Presently there is no mechanism for depots where farmers could drop their agricultural waste. The central government should fix a price for agricultural waste to make investments in 2G bioethanol production an attractive proposition.
- Rigid pricing mechanism: Sugars mills have to pay high prices for sugarcane set by the government even when there have been supplying gluts. The prices of both sugarcane and bio-ethanol are set by the central government.
Way ahead
- The government should provide greater visibility on the price of bioethanol that sugar mills can expect by announcing a mechanism by which the price of bio-ethanol would be decided.
- 2G bioethanol not only provided a clean source of energy but also help provide greater income to farmers and prevent them from having to burn agricultural waste which can be a major source of air pollution.

Babu ChunderSikur Chatterjee’s paper was the earliest record of a tornado’s dynamics in the history of meteorology, according to a study.
Try this PYQ:
Q. In the South Atlantic and South-Eastern Pacific regions in tropical latitudes, cyclone does not originate. What is the reason? (CSP 2015)
(a) Sea surface temperatures are low
(b) Inter-Tropical Convergence Zone seldom occurs
(c) Coriolis force is too weak
(d) Absence of land in those regions
What is a Tornado?
- A tornado is a rapidly rotating column of air that is in contact with both the surface of the Earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud.
- The windstorm is often referred to as a twister, whirlwind or cyclone winds blow counterclockwise in the Northern Hemisphere and clockwise in the Southern.
- Tornadoes come in many shapes and sizes, and they are often visible in the form of a condensation funnel originating from the base of a cumulonimbus cloud, with a cloud of rotating debris and dust beneath it.
- It is generally accompanied by extreme weather such as heavy downpours, hail storms, and lightning.
Who was Babu ChunderSikur Chatterjee?
- Chatterjee was an Indian scientist employed with the Surveyor General of India during the British colonial era.
- He was likely the first person to scientifically document a tornado’s path in 1865, a study from the Indian Institute of Tropical Meteorology (IITM), Pune, has claimed.
- Chatterjee had published his findings in a journal named Proceedings of the Asiatic Society of Bengal, in a paper titled ‘Note on a whirlwind at Pundooah’, near Hooghly.
- The paper described a tornado’s dynamics in meticulous detail and was accompanied by a sketch that mathematically depicted its scale, track and rotation.
His work
- Chatterjee quantitatively mapped the entire trail of á tornado’s destruction.
- He benefited from the rare opportunity to observe a tornado passing through a railway track where there were conveniently placed markers at predefined locations.
- This enabled him to observe and make clear measurements of the tornado’s direction, dynamics and path.

About Lingaraj Temple
- Lingaraja Temple is a temple dedicated to Shiva and is one of the oldest temples in Bhubaneswar, Odisha.
- It represents the quintessence of the Kalinga Architecture and culminating the medieval stages of the architectural tradition at Bhubaneswar.
- The temple is believed to be built by the kings from the Somavamsi dynasty, with later additions from the Ganga rulers.
- It is built in the Deula style that has four components namely, vimana (structure containing the sanctum), jagamohana (assembly hall), natamandira (festival hall) and bhoga-mandapa (hall of offerings), each increasing in the height to its predecessor.
- Bhubaneswar is called the Ekamra Kshetra as the deity of Lingaraja was originally under a mango tree (Ekamra) as noted in Ekamra Purana, a 13th-century Sanskrit treatise.
- The temple has images of Vishnu, possibly because of the rising prominence of Jagannath sect emanating from the Ganga rulers who built the Jagannath Temple in Puri in the 12th century.

Prelims level: Ceres and other dwarf planets
Mains level: Not Much
The dwarf planet Ceres, which lies in the asteroid belt between Mars and Jupiter now, has the status of an “ocean world”.
Note various dwarf planets and the criteria making a planet dwarf, as mentioned in the B2b section.
Ceres exploration
- The dwarf planet was first spotted by Giuseppe Piazzi in 1801, who assumed that Ceres was the missing planet between Mars and Jupiter.
- It was classified as a dwarf planet in 2006 and is the first dwarf planet to be orbited by a spacecraft.
- In 2015, NASA’s Dawn reached it to study its surface, composition and history.
What does it mean to be an “ocean world”?
- With a crust that mixes ice, salts, rock-forming minerals and other materials, Ceres looks to be a remnant “ocean world,” wearing the chemistry of its Old Ocean and records of the interaction on its surface.
- The observations from Dawn suggest the presence of briny liquid (saltwater) water under Ceres’s surface.
- Scientists have determined that Ceres has a brine reservoir located about 40 km deep and which is hundreds of miles wide, making the dwarf planet, “water-rich”.
Why do researchers study Ceres?
- Scientists are interested in this dwarf planet because it hosts the possibility of having water, something that many other planets do not have.
- Therefore, scientists look for signs of life on Ceres, a possibility that has also maintained scientists’ interest in the planet Mars, whose atmosphere was once warm enough to allow water to flow through it.
- Another reason why scientists are interested in that studying it can give insights about the formation of the Solar System since it is considered to be a fossil from that time.
Back2Basics: Dwarf Planets
- As of today, there are officially five dwarf planets in our Solar System.
- The most famous is Pluto, downgraded from the status of a planet in 2006.
- The other four, in order of size, are Eris, Makemake, Haumea and Ceres. The sixth claimant for a dwarf planet is Hygiea, which so far has been taken to be an asteroid.
- These four criteria are – that the body orbits around the Sun, it is not a moon, has not cleared the neighbourhood around its orbit and has enough mass for its gravity to pull it into a roughly spherical shape.

Prelims level: Bhadbhut Project, Hilsa Fish
Mains level: Not Much
The Gujarat government recently awarded the contract for a the Bhadbhut project in Bharuch, Gujarat. It has faced protests from local fishermen for its likely impact on fishing patterns, notably those of hilsa.
Make a note of major dams in India along with the rivers, terrain, major wildlife sanctuaries and national parks incident to these rivers.
What is the Bhadbhut Project?
- It is planned to be a 1.7-km causeway-cum-weir barrage with 90 gates, across the river Narmada, 5 km from Bhadbhut village, and 25 km from the mouth of the river, where it flows into the Gulf of Khambhat.
- The barrage will stop most of the excess water flowing out of the Sardar Sarovar Dam from reaching the sea and thus create a “sweet water lake” of 600 mcm (million cubic metres) on the river.
- The barrage will also have a six-lane road that will connect the left and right banks of the river and provide shorten the land distance between two large industrial estates in Surat and Bharuch.
- The project also aims to prevent flooding in years when rainfall is higher than normal.
- Embankments 22 km long will be made and will extend upstream towards Bharuch, from either side of the river.
- The project is part of the larger Kalpasar Project, which entails the construction of a 30-km dam across the Gulf of Khambhat between Bharuch and Bhavnagar districts.
- The reservoir is meant to tap the waters of the Narmada, Mahisagar and Sabarmati.
Why are fishermen upset?
- The barrage is expected to interfere with the migration and breeding cycle of hilsa.
- A marine fish, hilsa migrate upstream and arrives in the brackish water of the Narmada estuary near Bharuch for spawning usually during the monsoon months of July and August, and continue doing so till November.
- Once the barrage is built, it is expected to block its natural entry.
About Hilsa Fish
IUCN status: Least Concerned
- The Hilsa is a species of fish related to the herring, in the family Clupeidae.
- It is a very popular and sought-after food fish in the Indian Subcontinent.
- Though it’s a saltwater fish, it migrates to sweet waters.
- It is the national fish of Bangladesh and state symbol in the Indian states of West Bengal and Tripura.
- The fish contributes about 12% of the total fish production and about 1.15% of GDP in Bangladesh.

Prelims level: Death Valley, Mojave Desert
Mains level: Not Much
California’s Death Valley registered a temperature of 54.4 degrees Celsius or 129.9 degrees Fahrenheit on August 16, 2020, which, once verified, could be the hottest temperature ever recorded on Earth.
Some years back, there was a question in the mains:
Major hot deserts in the northern hemisphere are located between 20-30 degree north and on the western side of the continents. Why?
Death Valley and its location
- Death Valley is a desert valley in Eastern California, in the northern Mojave Desert, bordering the Great Basin Desert.
- It is one of the hottest places on Earth, along with deserts in the Middle East and the Sahara.
- The valley is extremely dry because it lies in the rain shadow of four major mountain ranges (including the Sierra Nevada and the Panamint Range).
- Moisture moving inland from the Pacific Ocean must pass eastward over the mountains to reach Death Valley; as air masses are forced upward by each range, they cool and moisture condenses, to fall as rain or snow on the western slopes.
- When the air masses reach Death Valley, most of the moisture has already been lost and there is little left to fall as precipitation.
Key factors leading to its high temperature
- Solar heating: The valley’s surface (consisting of soil, rocks, sand, etc.) undergoes intense solar heating because the air is clear and dry, and the land is dark and sparsely vegetated. This is especially noticeable in summer when the sun is nearly directly overhead.
- Trapping of warm air: Warm air naturally rises and cools; in Death Valley, this air is subject to continual reheating as it is trapped by high, steep valley walls and recycled back to the valley floor.
- Migration of warm air from other areas (advection): Warm desert regions adjacent to Death Valley, especially to the south and east, often heat air before it arrives in Death Valley.
- Warm mountain winds: As winds are forced up and over mountains (e.g., the numerous ranges west of Death Valley), the winds can be warmed in several ways. The resulting dry, warm winds are known as foehn winds.

Which of the statements given above is/are correct? (CSP 2018)
a) 1 only
b) 2 only
c) Both 1 and 2
d) Neither 1 nor 2
What is the move?
- Issuers will be able to send all details to their bank, thereby ensuring faster clearance of cheques above Rs 50,000.
- All cheques will be processed as per the information sent by the account holder at the time of issuance of cheques.
- This will cover approximately 20 per cent of transactions by volume and 80 per cent by value.
- It will make cheque payments safer and reduces instances of frauds.
What is Positive Pay Mechanism?
- Positive Pay is a fraud detection tool adopted by banks to protect customers against forged, altered or counterfeit cheques.
- It crosses verifies all details of the cheque issued before funds are encashed by the beneficiary.
- In case of a mismatch, the cheque is sent back to the issuer for examination.
- By following such a system, a bank knows of a cheque being drawn by the customer even before it is deposited by the beneficiary into his/her account.
How does the mechanism work?
- Under Positive Pay feature, the issuer will first share the details of the issued cheque like cheque number, date, name of the payee, account number, amount and the likes through his/her net banking account.
- Along with this, an image of the front and reverse side of the cheque is also required to be shared, before handing it over to the beneficiary.
- When the beneficiary submits the cheque for encashment, the details are compared with those provided to the bank through Positive Pay.
- If the details match, the cheque is honoured. However, in the case of mismatch, the cheque is referred to the issuer.
- In this way, any cheque where any sort of fraud has happened cannot be cleared at all and hence, a depositor’s money can be protected.

A Japanese ship recently struck a coral reef resulting in an oil spill of over 1,000 tonnes into the Indian Ocean near Mauritius.
Try this PYQ:
Q.Recently, “oil zapper’’ was in the news. What is it? (CSP 2011)
(a) It is an eco-friendly technology for the remediation of oily sludge and oil spills.
(b) It is the latest technology developed for undersea oil exploration.
(c) It is a genetically engineered high biofuel-yielding maize variety.
(d) It is the latest technology to control the accidentally caused flames from oil wells.
What caused the Mauritius oil spill?
- A Japanese vessel struck a coral reef resulting in an oil spill of over 1,000 tonnes into the Indian Ocean.
- The ship was carrying an estimated 4,000 tonnes of oil.
- The accident had taken place near two environmentally protected marine ecosystems and the Blue Bay Marine Park Reserve, which is a wetland of international importance.
How dangerous are oil spills?
- Oil spills affect marine life by exposing them to harsh elements and destroying their sources of food and habitat.
- Further, both birds and mammals can die from hypothermia as a result of oil spills.
- For instance, oil destroys the insulating ability of fur-bearing mammals, such as sea otters.
- It also decreases the water repellency of birds’ feathers, without which they lose their ability to repel cold water.
Some major incidents
- Some of the world’s largest oil spills include the Persian Gulf War oil spill of 1991 when more than 380 million gallons of oil was poured into the northern Persian Gulf by Iraq’s forces.
- The 2010 Deepwater Horizon oil spill in the Gulf of Mexico is also considered to be among the largest known accidental oil spills in history.
- Starting April 20, 2010, over 4 million barrels of oil flowed over a period of 87 days into the Gulf of Mexico.
How is the oil spill cleaned?
- There are a few ways to clean up oil spills including skimming, in situ burning and by releasing chemical dispersants.
- Skimming involves removing oil from the sea surface before it is able to reach the sensitive areas along the coastline.
- In situ burning means burning a particular patch of oil after it has concentrated in one area.
- Releasing chemical dispersants helps break down oil into smaller droplets, making it easier for microbes to consume, and further break it down into less harmful compounds.
- Natural actions in aquatic environments such as weathering, evaporation, emulsification, biodegradation and oxidation can also accelerate the recovery of an affected area. But these occur differently in freshwater and marine environments.

Prelims level: National flag
Mains level: NA
The final design of the Indian National Flag, hoisted by PM Nehru on August 16, 1947, at Red Fort, had a history of several decades preceding independence.
Note various personalities involved in the development of our National flag. It may be no wonder to accept a personality-based question on such topics.
Story of our National Flag: A timeline
(1) Public display for first time
- Arguably the first national flag of India is said to have been hoisted on August 7, 1906, in Kolkata at the Parsee Bagan Square (Green Park).
- It comprised three horizontal stripes of red, yellow and green, with Vande Mataram written in the middle.
- Believed to have been designed by freedom activists Sachindra Prasad Bose and Hemchandra Kanungo, the red stripe on the flag had symbols of the sun and a crescent moon, and the green strip had eight half-open lotuses.
(2) In Germany
- In 1907, Madame Cama and her group of exiled revolutionaries hoisted an Indian flag in Germany in 1907 — this was the first Indian flag to be hoisted in a foreign land.
(3) During the Home Rule Movement
- In 1917, Dr Annie Besant and Lokmanya Tilak adopted a new flag as part of the Home Rule Movement.
- It had five alternate red and four green horizontal stripes, and seven stars in the saptarishi configuration.
- A white crescent and star occupied one top corner, and the other had Union Jack.
(4) Final version by Pingali Venkayya
- The design of the present-day Indian tricolour is largely attributed to Pingali Venkayya, an Indian freedom fighter.
- He reportedly first met Mahatma Gandhi in South Africa during the second Anglo-Boer War (1899-1902), when he was posted there as part of the British Indian Army.
- Years of research went into designing the national flag. In 1916, he even published a book with possible designs of Indian flags.
- At the All India Congress Committee in Bezwada in 1921, Venkayya again met Gandhi and proposed a basic design of the flag, consisting of two red and green bands to symbolise the two major communities, Hindus and Muslims.
(5) During Constituent Assembly
- On July 22, 1947, when members of the Constituent Assembly of India, the first item on the agenda was reportedly a motion by Pandit Nehru, about adopting a national flag for free India.
- It was proposed that “the National Flag of India shall be horizontal tricolour of deep saffron (Kesari), white and dark green in equal proportion.”
- The white band was to have a wheel in navy blue (the charkha being replaced by the chakra), which appears on the abacus of the Sarnath Lion Capital of Ashoka.

A team of researchers at the Indian Institute of Science Education and Research (IISER), Bhopal, has conducted a study on seed germination that could have a major impact on agriculture.
What is the study about?
- The study aims to determine the optimum timing of seed germination and thus ensure high plant yields.
- It focused on the interplay between plant hormones like abscisic acid (ABA) which inhibit the sprouting of the seed and environmental cues like light (which promotes the sprouting process) and darkness.
Note the following plant hormones and their functions:
|
Hormone
|
Function
|
| Ethylene |
Fruit ripening and abscission |
| Gibberellins |
Break the dormancy of seeds and buds; promote growth |
| Cytokinins |
Promote cell division; prevent senescence |
| Abscisic Acid |
Close the stomata; maintain dormancy |
| Auxins |
Involved in tropisms and apical dominance |
What is Abscisic Acid?
- Humans have glands that secrete hormones at different times to stimulate body processes such as growth, development, and the breaking down of sugars.
- Plants also have hormones that stimulate processes that are necessary for them to live.
- Abscisic acid is a plant hormone involved in many developmental plant processes, such as dormancy and environmental stress response.
- Abscisic acid is produced in the roots of the plant as well as the terminal buds at the top of the plant.
Function of Abscisic Acid
Abscisic acid is involved in several plant functions.
- Plants have openings on the bottom side of their leaves, known as stomata. Stomata take in carbon dioxide and regulate water content. Abscisic acid has been found to function in the closing of these stomata during times when the plant does not require as much carbon dioxide or during times of drought when the plant cannot afford to lose much water through transpiration.
- One of the crucial functions of abscisic acid is to inhibit seed germination. Abscisic acid has been found to stop a seed from immediately germinating once it has been placed in the soil. It actually causes the seed to enter a period of dormancy.
- This is of great benefit to the plants because most seeds are formed at the end of the growing season, when conditions would not be favorable for a new plant to sprout. The abscisic acid causes the seed to wait until the time when conditions are more favorable to grow. This ensures greater success in the plant’s ability to grow and reproduce successfully.
- ABA functions in many plant developmental processes, including seed and bud dormancy, the control of organ size and stomatal closure. It is especially important for plants in the response to environmental stresses, including drought, soil salinity, cold tolerance, freezing tolerance, heat stress and heavy metal ion tolerance.

SPT0418-47, a golden halo glinting 12 billion light-years away is the farthest galaxy resembling our Milky Way was recently spotted by astronomers.
Try this PYQ:
Which of the statements about black holes in space is/are correct? (CSP 2016)
- It is a region in space where the pulling force of gravity is so strong that light is not able to escape.
- It can result from the dying stars.
Select the correct answer using the code given below:
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2
SPT0418-47
- The galaxy, called SPT0418-47, is so far away that it took billions of years for its light to reach Earth and so our image of it is from deep in the past.
- It was picked up by the powerful Alma radio telescope in Chile using a technique called gravitational lensing, where a nearby galaxy acts as a powerful magnifying glass.
- This was when the Universe was 1.4 billion years old — just 10% of its current age — and galaxies were still forming.
- It has features similar to our Milky Way — a rotating disc and a bulge, which is the high density of stars packed tightly around the galactic centre.
What makes it special?
- This is the first time a bulge has been seen this early in the history of the Universe, making SPT0418-47 the most distant Milky Way look-alike.
- Thus the infant star system challenges our understanding of the early years of the Universe.
- Researchers expect these young star systems to be chaotic and without the distinct structures typical of mature galaxies like our Galaxy.
- This unexpected discovery suggests the early Universe may not be as chaotic as once believed and raises many questions on how a well-ordered galaxy could have formed so soon after the Big Bang.
Back2Basics: Milky Way
- The Milky Way is the galaxy that contains our Solar System, with the name describing the galaxy’s appearance from Earth.
- It appears like a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye.
- From Earth, the Milky Way appears as a band because its disk-shaped structure is viewed from within.
- Galileo Galilei first resolved the band of light into individual stars with his telescope in 1610.
- Until the early 1920s, most astronomers thought that the Milky Way contained all the stars in the Universe.
- Following the 1920 Great Debate between the astronomers Harlow Shapley and Heber Curtis, observations by Edwin Hubble showed that the Milky Way is just one of many galaxies.

Prelims level: Hornbill
Mains level: NA
A study based on satellite data has flagged a high rate of deforestation in a major hornbill habitat in Arunachal Pradesh.

Q. In which of the following regions of India are you most likely to come across the ‘Great Indian Hornbill’ in its natural habitat? (CSP 2016)
(a) Sand deserts of northwest India
(b) Higher Himalayas of Jammu and Kashmir
(c) Salt marshes of western Gujarat
(d) Western Ghats
About Great Indian Hornbill
IUCN status: Vulnerable (uplisted from Near Threatened in 2018), CITES: Appendix I
- The great hornbill (Buceros bicornis) also known as the great Indian hornbill or great pied hornbill, is one of the larger members of the hornbill family.
- The great hornbill is long-lived, living for nearly 50 years in captivity.
- It is predominantly fruit-eating, but is an opportunist and preys on small mammals, reptiles and birds.
- Its impressive size and colour have made it important in many tribal cultures and rituals.
- A large majority of their population is found in India with a significant proportion in the Western Ghats and the Nilgiris.
- The nesting grounds of the birds in the Nilgiris North Eastern Range are also believed to support some of their highest densities.
Their ecological significance
- Referred to as ‘forest engineers’ or ‘farmers of the forest’ for playing a key role in dispersing seeds of tropical trees, hornbills indicate the prosperity and balance of the forest they build nests in.
Threats
- Hornbills used to be hunted for their casques — upper beak — and feathers for adorning headgear despite being cultural symbols of some ethnic communities in the northeast, specifically the Nyishi of Arunachal Pradesh.
- Illegal logging has led to fewer tall trees where the bird’s nest.
Back2Basics: Hornbill Festival
- The Hornbill Festival is a celebration held every year from 1 – 10 December, in Kohima, Nagaland.
- The festival was first held in the year 2000.
- It is named after the Indian hornbill, the large and colourful forest bird which is displayed in the folklore of most of the state’s tribes.
- Festival highlights include the traditional Naga Morungs exhibition and the sale of arts and crafts, food stalls, herbal medicine stalls, flower shows and sales, cultural medley – songs and dances, fashion shows etc.

From UPSC perspective, the following things are important :
Prelims level: Meteor terminology
Mains level: Not Much
The Perseids meteor shower is going to be active from August 17-26.
Try this question from CSP 2014:
Q.What is a coma, in the content of astronomy?
(a) Bright half of material on the comet
(b) Long tail of dust
(c) Two asteroids orbiting each other
(d) Two planets orbiting each other
What is the Perseids meteor shower?
- The Perseids meteor shower peaks every year in mid-August. It was first observed over 2,000 years ago.
- The Perseids occur as the Earth runs into pieces of cosmic debris left behind by the comet Swift-Tuttle.
- The cloud of debris is about 27 km wide, and at the peak of the display, between 160 and 200 meteors streak through the Earth’s atmosphere every hour as the pieces of debris.
- They travel at the speed of some 2.14 lakh km per hour; burn up a little less than 100 km above the Earth’s surface.
What are Meteor Showers?
- Meteors are bits of rock and ice that are ejected from comets as they manoeuvre around their orbits around the sun.
- As meteors fall towards the Earth, the resistance makes the space rocks extremely hot and, as meteorites pass through the atmosphere, they leave behind streaks of glowing gas that are visible to the observers and not the rock itself.
- Meteor showers, on the other hand, are witnessed when Earth passes through the trail of debris left behind by a comet or an asteroid.
- When a meteor reaches the Earth, it is called a meteorite and a series of meteorites, when encountered at once, is termed as a meteor shower.
- According to NASA, over 30 meteor showers occur annually and are observable from the Earth.
Where do the Perseids come from?
- The comet Swift-Tuttle, which was discovered in 1862 by Lewis Swift and Horace Tuttle, takes 133 years to complete one rotation around the sun.
- The last time it reached its closest approach to the sun was in 1992 and will do so again in 2125.
- Every time comets come close to the sun, they leave behind dust that is essentially the debris trail, which the Earth passes through every year as it orbits around the Sun.
