The mission carried a number of scientific instruments that studied the Moon’s surface, composition, and environment. With these instruments, a number of groundbreaking discoveries were made by Chandrayaan 3 for the first time in history. 

The Chandrayaan 3 spacecraft discovered many elements on the moon, as well as massive temperature variations, a thin plasma environment, and mysterious sound activity. Moon’s south pole can be better understood with these discoveries. 

The focus of this article will be on Chandrayaan 3 discoveries. We have explained important 4 discoveries in detail in this article. It also provides some context for each discovery, explaining why it is important and what it could mean for our understanding of the Moon. This article is a good resource for anyone who wants to learn more about the Chandrayaan 3 mission and its discoveries.

Let’s examine the recent discoveries made by Chadrayaan 3 on the moon in more detail –

1. Massive Temperature Variations on the Lunar Surface

An interesting discovery was made by Chandrayaan 3’s Pragyan rover when it measured the soil temperature of the moon. A massive temperature variation has been observed on the surface of the moon. The temperature ranges from minus 10 degrees Celsius to around 70 degrees Celsius. 

In its observations of lunar topsoil, it was found that the surface temperature of the Moon is around 50 degrees Celsius. It was almost 70 degrees Celsius at 20 mm height above the ground. Temperatures dropped to minus 10 degrees Celsius at minus 80mm depth, which is below ground level.

To understand the moon’s thermal behavior, ChaSTE (Chandra’s Surface Thermophysical Experiment) measures the temperature profile of its topsoil around its poles. This instrument has a temperature probe with a controlled penetration mechanism capable of reaching a depth of 10 cm (1 cm = 10 mm). Ten temperature sensors are mounted on the probe.

Following is a graph showing the temperature variations at various depths on the lunar surface, as recorded by the probe – 

“This is the first such profile for the lunar south pole. Detailed observations are underway.”

ISRO said

Why is the Measurement of Massive Temperature Variation on the Lunar Surface Important?

There are several reasons why measuring massive temperature variations on the lunar surface is important:

• Using it, we can gain a deeper understanding of the Moon’s environment. Due to its thin atmosphere, the Moon cannot regulate its temperature as well as Earth’s. As a result, the Moon’s surface and inhabitants may experience extreme temperature variations.
• Our understanding of the Moon’s history can be enhanced by measuring its massive temperature variations. Moon’s surface is constantly changing, and temperature variations can play an important role. A better understanding of the Moon’s evolution can be gained by studying temperature variations.

• It can also help us understand other planetary bodies. Extreme temperature variations are not limited to the Moon. These variations are also experienced by other bodies, such as Mercury and Mars. It is possible to learn more about how these variations affect other planetary bodies by studying the Moon.

• Measuring massive temperature variations on the moon can help us develop future lunar exploration strategies. Astronauts who wish to explore the Moon need to be aware of the extreme temperature fluctuations and protect themselves accordingly. Taking measures to avoid cold exposure could include wearing special suits that protect them from the cold or planning their activities carefully.

In order to explore the moon in the future, the measurement of the massive temperature variation of the lunar surface is a valuable resource for scientists and engineers. The data will help them to develop safer and more efficient ways to explore the Moon.

2. Discovеry of Sulphur on the Moon – One of The Most Important Chandrayaan 3 Discoveries

Several elements have been detected by the Pragyan rover near the lunar south pole. Sulphur has been found near the south pole of the moon. It has also detected the presence of Aluminum, Calcium, Chromium, Iron, Titanium, Manganese, Silicon, and Oxygen (Al, Ca, Cr, Fe, Ti, Mg, Si & O).

LIBS, the Laser-Induced Breakdown Spectrometer on the rover, made these discoveries. Using a powerful laser, this tool helps scientists understand what the Moon is made of. Using intense laser pulses, LIBS analyzes the composition of materials.

Why the discovery of sulphur is important?

The discovery of Sulphur (S) on the south pole of the Moon is very important because of –

• Since other tools that orbit the Moon couldn’t detect sulfur, the discovery of sulphur is very important.

• It is the first time that sulphur has been found on the Moon in such abundance, and the discovery could shed light on how the moon formed and evolved. 

• Sulphur is more common in other parts of the solar system, including Jupiter’s moon Io but it is relatively rare on Earth.

• As a result of sulphur being discovered on the Moon, the Moon may have been more volcanically active in the past than previously thought. 

• There is also a possibility that the sulphur on the moon is a sign of water ice. It is common in other parts of the solar system to find sulphur and water ice together. 

• If water ice is found on the Moon, it could be used as a fuel and water source for future lunar exploration.

Sulphur being discovered on the Moon is a major discovery that brings us closer to understanding the Moon and its potential for further exploration. This is why Sulphur is one of the most important Chandrayaan 3 discoveries. ISRO scientists will continue to study the Moon in order to uncover even more secrets of the Moon.

3. Plasma Measurement on the Moon For The First Time

Chandrayaan 3 has measured the plasma environment above the Moon’s South Pole for the first time. This experiment measured electron density near the moon’s surface. The measurements are made by the RAMBHA-LP payload aboard the Vikram lander. According to this experiment, the number density ranges from approximately 5 million to 30 million electrons per cubic meter. This indicates that the plasma is relatively thin. 

The plasma is thought to be created by the interaction of the solar wind with the Moon’s atmosphere. These electrons are liberated from the powerful rays from the sun hitting the lunar surface. The density of this electron increases during the day, while at night it is almost zero.

Why the Measurement of Plasma is Important?

Plasma measurements on the Moon can help us understand a number of things, like:

• Now, scientists will gain a greater understanding of the Moon’s atmosphere and its interaction with the solar wind, thanks to Chandrayaan 3 discoveries & measurements.

• Radio communication between the Moon and Earth could be interfered with by the plasma, so it is important to understand its properties in order to mitigate its effects.

• An overview of the origins and evolution of the atmosphere of the Moon can be obtained.

• Measuring the plasma on the Moon is also crucial to understanding the plasma environment around other solar system bodies, like Mars and Mercury. Observing the Moon’s plasma environment will give us a better understanding of how plasma behaves in different environments and how it affects these bodies.

• Using plasma to shield astronauts from radiation can help protect them from space harmful radiation.

• Moreover, the measurements may be useful for future lunar explorations. 

So, taking measurements of plasma on the Moon is a challenging, but essential & part of research. Plasma measurements on the Moon can help us understand the Moon, the solar system, and the universe.

4. A Mysterious Natural Event Detected

A mysterious natural event has been recorded on the south pole of the moon by the Vikram lander. However, the detection of its source is yet to be identified.

An instrument on the Vikram lander, called ILSA (The Instrument for Lunar Seismic Activity), detected this event. The ILSA instrument detects vibrations on the lunar surface using a seismometer.

There was no damage to the Vikram lander during the brief event, which lasted only a few seconds. However, the event is still significant because a seismic event has never been recorded in this area of the Moon before.

There appears to have been a seismic event, although its exact nature is still unknown.

Several things could cause it, including a meteorite impact, a lunar quake, or another collapse.

According to ISRO Scientists

During the coming days and weeks, they plan to investigate this event further and we will learn more about its nature. 

It is still unclear how, or what, the event originated. Scientists are still trying to find the answers to questions like What was its exact nature, and source?

By answering these questions, scientists will be able to gain a better understanding of the Moon and its environment. We have made significant progress in our understanding of the Moon with the discovery of this mysterious natural event. It is a reminder that many mysteries still exist in our solar system.

Conclusion

As of now, Chandrayaan 3 has made several important discoveries about the Moon so far. Because Chandrayaan 3 is still ongoing, these discoveries are just a few of the many. The Moon is full of secrets, and scientists are eager to discover them.

The Chandrayaan 3 mission is a major milestone in India’s space program, and it could revolutionize how we understand the Moon. Discoveries by Chandrayaan 3 demonstrate the power of science to uncover new information and explore the universe.

A bright future lies ahead for lunar exploration, and the Chandrayaan 3 mission is paving the way.

FAQ’s

The post 4 Best Chandrayaan 3 Discoveries About the Moon So Far appeared first on Go Physics.

The team of researchers at the International School of Advanced Studies (SISSA) figured out the number of stellar black holes. They tracked down the evolution of stars in the universe. They calculated the frequency at which the binary star systems transform into black holes. The rate of formation of stars that could eventually transform into black holes was calculated.

Watch this video for the complete visual explanation of this discovery of black holes –

What is a black hole?

A black hole is an area of space where the gravitational field is so powerful that even light cannot escape. Because stuff has been crammed into such a small space, where the gravity is extremely powerful. Because no light can exit a black hole, no one can see it. That’s why black holes are undetectable. Space telescopes that are equipped with specialized pieces of equipment can help to detect black holes.

How big are these black holes?

Black holes can be large or small in size. Scientists believe that the tiniest black holes are as small as an atom. “Stellar” black holes are another kind of black hole. It has a mass up to 20 times that of the sun. “Supermassive” black holes are the largest. The aggregate mass of these black holes is more than a million suns.

Now, the next question arises- What Causes the Formation of Black Holes?

When the core of a massive star collapses in on itself, it creates a stellar black hole.

The scientists explored the demographics of stellar-mass black holes. They discovered that stellar-mass black holes hold about 1% of the Universe’s total ordinary (baryonic) stuff. Surprisingly, they discovered that the Universe contains approximately 40 trillion- 40 billion (i.e., about 40 x 1018, i.e., 4 followed by 19 zeros!) Of Black Holes.

As a result, there are a lot of black holes in the cosmos. And, come to think of it, this is only the first of what will likely be a series of papers. If this is where they’re starting, we’re looking forward to seeing what the SISSA team comes up with next.

In astronomy what we know before the discovery of the Hubble Telescope and what we know after the Hubble Telescope is contrasting. But that is going to be changed very soon. Because James Webb Space Telescope (JWST) is not only bigger than the Hubble but also about 100 times more powerful. We, humans, are incapable to create a machine that can take us to our past and future but we have definitely created a machine that certainly can help us to look back in time. NASA created the James Webb Space Telescope (JWST) in collaboration with the European Space Agency (ESA) and the Canadian Space Agency (CSA). The Hubble Space Telescope will be replaced by it. NASA Administrator James E. Webb, who served from 1961 to 1968 is honored with the telescope’s name. On December 25, 2021, JWST was launched aboard Ariane flight VA256.

Watch this video for the complete visual explanation of the James Webb Space Telescope –

Or continue reading…

It takes 10,000 years for light from an object 10,000 light-years away to reach Earth. So, the further out in space you look, the further back in time you are looking. We can look back in time by detecting infrared light. Because infrared light has been traveling across space for as long as 13.5 billion years. Engineers optimized James Webb for specifically detecting the faint infrared light. The James Webb Space Telescope will cover the wavelengths between 0.6 micrometers to 28 micrometers covering most of the infrared region. Thereby it will provide images of the first galaxies formed and will observe unexplored planets around distant stars.

Webb’s mirrors are coated with a golf ball’s worth of pure gold, allowing them to reflect infrared light more effectively. The typical thickness of the gold is 1000 Angstroms. This means the coating is so thin that human hair is 1,000 times thicker! A thin layer of amorphous (non-crystalline) sio2 or glass, is deposited on top of the gold to protect it from scratches. In comparison to the Hubble Space Telescope, James Webb’s camera has a 15-fold broader field of vision. It captures 6.25 times more light and the sensors are highly sensitive to infrared light.

Then there arises the problem of a cosmic element called Dust. It absorbs visible light and works like a barrier between our telescope and the stars or galaxies we are trying to observe. But Webb’s primary infrared watching capabilities will penetrate through the problem. Thus, opening a newer more detailed view of the cosmos that we have never seen before. Webb’s heat-sensitive eyesight is shielded by a tennis-court-sized kite-shaped-sun shield. It provides the telescope with the equivalent of 1 million SPF protection.

The plan of the James Webb Space Telescope (JWST) will be to stare deeply at one patch of sky over an extended period. It will gather as much light and information as possible from the most distant and oldest galaxies. It may be feasible to determine when and how the Dark Ages ended using this information, but there are still many other crucial discoveries to be uncovered. Unraveling this scenario, for example, could aid in explaining the nature of dark matter, a mysterious kind of matter that accounts for nearly 80% of the universe’s mass. Webb will not only watch the far side of the universe but also watch inside our solar system. Webb will unravel many things about our solar system that we have never known. It will also give us amazing pictures of planets and may help us to find planet 9. Well if it exists.

Or continue reading…

Exoplanets are the ones that orbit a star other than our Sun. The Hubble telescope measured its spectrum. It is located in the constellation called Antila. You can spot it in the southern celestial hemisphere. It is about 150 light-years away from the Earth. The mass of this exoplanet is 23 times the mass of Earth. It is close to its host star zipping around a red dwarf about every two days. The host star is cooler and less than half the size of our Sun. NASA says this planet will further be analyzed by the James Webb Space Telescope.

The amount of water can tell us that it was formed inside or outside the water ice line. But right now, scientists are unable to calculate the amount of water. Thought the atmosphere of TOI-674B is much easier to study than the other exoplanets. The discovery of planets in size-class between Neptune and Jupiter is extremely rare. So, this exoplanet is very important to us. Many questions remain to answer, like how much water vapor its atmosphere hold. Does this indicate the presence of life? The Webb promises a golden age study of exoplanet’s atmosphere to answer all such questions. We’ll bring to you the details of the James Webb Telescope in our future articles.

Watch this video for the complete visual explanation of this giant red star explode into a supernova –

Or continue reading…

When a star reaches its end then, it explodes releasing energy and chemicals into the universe; this dramatic yet spectacular explosion is known as Supernova. This journey of a star up to this supernova starts from its birth. The recipe for the formation of a star is very easy and it needs only a few ingredients like dust and gas. These ingredients are available in the universe is an abundant scale. Gravity is a chef here who combines these ingredients which leads to the formation of a hotter and denser core. Further, the hydrogen gas converts into helium due to an amazing process known as Nuclear Fusion. If a star is a vehicle, the core of helium acts as an Engine and helium as a fuel which keeps the star running that is ‘Alive’.

The core pushes the star outward and Gravity keeps pushing the star inwards. This fight between the equal forces keeps the star stable. But, this dramatic conflict comes to an end when the core of the star runs out of fuel (Helium) and Gravity wins. Then star starts to crunch inwards and suddenly explodes into a supernova. Before explosion it again inflates like a balloon into a Red Giant, Red color is due to the low temperature of the outer layer. Stars come in a range of colors: blue, white, green, yellow, orange, and Red. The red one is the lowest in temperature and the blue one is the higher in temperature; strange, isn’t it? The star becomes more luminous in the last stage and when it explodes then it can outshine the entire galaxy for a few days or even for months.

Stars are rich in gases, minerals, and metals like iron, calcium, phosphorus, magnesium, etc. Hence, when these supernovas take place all the material is thrown into the universe. These events provide all the ingredients required for water and life. These events inspired Carl Sagan to say his iconic line, ‘We all are made up of star stuff.’

Scientists of Berkeley had been watching this star since January 2020 and after 9 months the first-ever observation of a supernova of a red giant is noted. This will really help to explore the stellar behavior and further research. The scientists are already on the quest of observing the next supernova after this SN2020tlf. There are many red giants in our night sky, Betelgeuse from the Orion constellation is also one of them. This first-time observation of such a violent event already opened a thousand doors to the answers to the stellar mysteries.

March End -Trio of Planets Bunched Together

During the end of March, Mars, Saturn, and Venus will appear extremely close to each other. Those who wake up early will be able to witness the trio. The three planets will be gathered in the early morning sky. This will happen during the last two weeks of March.

April 30 – Partial Solar Eclipse

When the Moon covers only a part of the Sun’s disk in the sky, a partial solar eclipse occurs. The partial solar eclipse will appear on 30 April. It will be visible in parts of Antarctica and throughout southern South America. Use solar filters to look at the Sun and try to imitate the crescent moon.

May 1 – Venus And Jupiter Conjunction

Jupiter will appear to be next to Venus planet. It will appear just before sunrise. There is a vast distance between Venus and Jupiter. But sometimes, our field of view can do wonders. The celestial illusion will create sight in which both the planets will appear to be right next to each other. On 1st May, the two planets will be just 14 arcminutes apart.

May 15 to May 16 – ‘Blood Flower Moon’ Eclipse

A total lunar eclipse occurs when the Earth is perfectly aligned between the Moon and the Sun. The shadow of Earth blocks all the reflected light reaching from the Moon. It will be a major astronomical event of 2022 as the moon will turn into copper-red color. It will be visible from Canada, South America, and the US. The eclipse will last for 84 minutes.

June 14 – Biggest Full Moon

A supermoon occurs when there is a Full Moon, that is closest to the Earth. It results in a full moon that is slightly brighter and bigger than others. The first supermoon of 2022 will occur on June 14.

August 13 – Perseids Meteor Shower

Perseids are the most popular meteor shower in the Northern Hemisphere. It is associated with the comet Swift-Tuttle. It is capable of producing up to 100 meteors per hour. This year, the full moon will block up the visibility of the fireballs. The bright ones would still be visible regardless of the moonlit sky.

Here are our favorite 7 moments worth sharing with you all –

1. Helicopter in Another Planet

NASA’s highly advanced perseverance rover landed on Mars in February. It resulted in the first-ever aircraft to make a controlled flight on another planet. It was NASA’s solar-powered Ingenuity Mars Helicopter that made headlines in April 2021. The spacecraft will spend the next two years on the red planet.

2. The 5ᵗʰ Fundamental Force

The rate at which the orientation of muons’ magnetic poles lurched was different from theoretical predictions. This is following the research with the experiment with Muon g-2 at Fermilab in Batavia. This odd behavior suggests that some hidden particles are influencing the magnetic properties of muons. It also gives a hint towards the fifth fundamental force.

3. The Detailed View of a Sunspot Ever

A team of scientists from Hawaii captured the most detailed image of a sunspot at the world’s largest solar observatory. The technique of adaptive optics they used, corrects the light distortions created by molecules of our atmosphere. The darkest part of the image reflects the coldest region. For the Sun, the coldest part means 200 times hotter than the room temperature. 

4. Cosmic Hum Detected By Voyager 1

NASA’s Voyager 1 detected a mysterious humming sound in interstellar space, 14 billion miles from earth. This discovery confirmed that interstellar space is not completely vacuum. The persistent “hum” represented the background noise present in the immense regions between the star medium. 

5. The Map of The Dark Matter

A group of 400 scientists obtained the largest ever map of dark matter. The amount of dark matter can be calculated by observing the light that reaches us. Distorted light points towards a huge amount of matter that is bending the light. This is called gravitational lensing. The dark matter magnifies the light from distant galaxies behind it. The map covers the southern hemisphere sky.

6. James Webb Space Telescope Launched

After 30 years of planning and development, we launched the greatest telescope in the history of astronomy. It is headed to a location known as the Second Lagrange point. It took over 27 days to trek the 15,00,000 km distance from earth. It promises to provide a glimpse of the universe as it existed when the earliest galaxies formed. 

Watch – Nasa’s James Webb Space Telescope has reached its final destination 😍

7. Megastructure Of Galaxies Identified

The galaxy size smudge on the night sky was believed to be the remnant of a long-ago supernova. But a recent study of X-ray data revealed a matching smudge on the other side of the Milky Way. It depicts that there is a pair of galaxy size bubbles 45,000 light-years across. Astronomers believe that it might be the evidence of an eruption million years ago.

These are the most exciting scientific discoveries of 2021. Let’s move forward with the hope that 2022 will be as awesome as 2021.

He also increased the understanding of the atomic processes responsible for the properties of matter and of the forces governing the structures of atomic nuclei. He studies nuclear reactions and reaction cross-sections. In 1943, he was asked to be the head of the Theoretical Division at Los Alamos on the Manhattan Project. He also received the Noble prize for physics (1967) for his work on the production of energy in stars.

He was a German-British physicist who worked on lowering temperatures below the point previously done by the Joule-Thomson effect. His work reached a low of 20 millionths of a degree above absolute zero. He used paramagnetic molecules at low temperatures and allowed their orientation to randomize. It abstracted the further heat and lowered the temperature still further.

He was a British scientist in solid-state physics who was a joint winner of the Noble Prize for physics for research on the determination of crystal structures in 1915. During WW I, he was appointed as an incharge of research on the detection and measurement of underwater sounds in connection with the location of submarines. He also constructed the wavelengths of X-rays. He was knighted in 1920.

She was a Canadian nuclear physicist who contributed a lot to the new science of radioactivity. She was probably the first to observe the recoil of the atomic nucleus during the emission of the nuclear particles at radioactive decay. Along with Rutherford, she demonstrated that the diffusion of the emanations of radium behaved like gas as well as had a high molecular weight. She died due to leukemia.

He was an American astronomer who is known for discovering the 4 satellites of Jupiter. While photographing the 8th moon of Jupiter with the 36-inch Crossley reflector in 1914, he discovered the 9th satellite. He discovered two more satellites while working at Mt. Wilson Observatory. He also computed the orbits of several comets. His work was to observe the sun with the 150-foot solar tower telescope and to produce annual reports on sunspot activity. He measured the temperature of the moon, sunspots, and stars with Edison Pettit.
