Chandrayaan 2: Vikram Lander lost contact with ISRO, data analysis continues

Chandrayaan 2: Vikram Lander lost contact with ISRO, data analysis continues

Contact with India's moon lander Vikram was lost when it was moving towards the lunar surface in the early hours of Saturday. ISRO Chairman K.K. Sivan said the contact was broken when Vikram was 2.1 kilometers away from the moon's landing at the south pole. ISRO Chief K Sivan said that data is still awaited. While this news showed disappointment among ISRO scientists, Prime Minister Narendra Modi encouraged the ISRO scientists and said that you have done a very good job.

He said that there will be ups and downs in life and this journey will continue. Prime Minister Narendra Modi said, "When the mission is big, one should dare to overcome despair. I congratulate you all very much. You have done great service to the human race of the country."
ISRO Chairman K.K. Sivan said the contact was broken when Vikram was 2.1 kilometers away from the moon's landing at the south pole. Vikram lost contact just before landing on the moon.
ISRO is waiting for data. There is disappointment among scientists due to the loss of contact with Chandrayaan just before the moon. The night before, Chandrayaan-2 was to land on the lunar surface at one o'clock at 52 minutes 54 seconds. Prime Minister Narendra Modi also reached the ISRO Center to witness this historic moment.

The process of bringing the lander to the moon's surface at around one o'clock in the night was started, but while coming down on the moon, it lost contact with the ground station at an altitude of 2.1 km. 'Vikram' successfully completed the 'Rough Breaking' and 'Fine Breaking' stages, but before the 'soft landing' it lost contact with the station on earth. Along with this, the lines of despair on the faces of scientists and people of the country were covered.

Amidst the nationwide wait for Vikram Lander's soft 'landing at the south pole of the lunar surface, ISRO said on Friday that things were proceeding as planned for the much-awaited landing. Before landing on the south pole of the moon of Vikram Lander under Chandrayaan-2 mission, Prime Minister Narendra Modi said that this campaign reflects the spirit of superior Indian talent and austerity.

Prime Minister Modi tweeted that crores of Indians will benefit from its success. Indian Space Research Organization (ISRO) president K Sivan said, "We are eagerly waiting for this (landing)." Everything is happening according to plan. The lander 'Vikram' will make a 'soft landing' on the lunar surface between one and a half hours today.


According to ISRO, the lander is equipped with three scientific instruments that will carry out scientific experiments on the lunar surface and subsurface, while there are two scientific instruments with the rover that will enhance understanding related to the lunar surface. With successful 'soft landing', India will become the fourth country in the world after Russia, America and China to achieve this feat.

With this, India will become the first country in the world to reach the moon's South Pole region while writing a new chapter in space history. Sivan recently said that the proposed 'soft landing' would be a heart-stopping situation as ISRO has never done this before.

What is blackhole || structure || observability

What is Blackhole Structure, Observability

Everyone wants to know about black hole that how it looks. Many space agency are trying to find the picture of real blackhole structure. They want to know about the structure and observability. They are tried many research to find the black hole structure.

So in this post I want to tell about what is black hole and it's structure and observability.

What is blackhole || structure || observability


Introduction of Blackhole

A blackhole is an area of spacetime, which shows such strong gravitational effects that nothing can escape from it - such as light particles and electromagnetic radiation.

The theory of general relativity predicts that a sufficiently compact mass may distort space time to create a blackhole. The extent of the area from which no escape is possible, the event is called horizon.

Although the event horizon has a lot of impact on the fate and circumstances of any object, yet no locally-identifiable features are seen. In many ways, a blackhole works like a perfect black body, because it does not reflect light.

Apart from this, quantum field theory predates the winding spacetime, that event horizons emit Hawking radiation, as opposed to its mass in the form of dark body temperature of the same spectrum.
This temperature is on the order of billions of kelvin for the blackhole of stellar mass, which is essentially impossible to observe it.

When the stars fall at the end of their life cycle, the stellar mass is expected to become blackholes. After the formation of a blackhole, it can continue to develop by absorbing the surrounding mass.

By absorbing other stars and merging with other blackholes, millions of solar masses (M form) can become supermassive blackholes. The consensus is that there are supermassive blackholes in the centers of most galaxies.

Read: NASA pulled out India's anti-satellite test-Mission Gaganyan


The idea of an object in space is so large and intensive that light could not survive for centuries. The most famous, blackhole prediction was made by Einstein's theory of general relativity, which showed that when a massive star dies, it leaves behind a small, dense residue core.

If the mass of the core is more than three times the mass of the Sun, then the equations showed, the gravitational force overwhelms all other forces and produces a blackhole.

Scientists can not inspect the blackhole directly with the telescope, which detect X-ray, light or other forms of electromagnetic radiation. However, we can detect the presence of blackholes and find out their effect on other nearby issues and study them.

If a blackhole interstellar passes through a cloud of matter, for example, it will attract incoming in a process known as accretion. A similar process can be passed on near a normal star blackhole. In this case, the blackhole can separate the star because it pulls it toward it.

 As the attracting material is sharp and warm, it emits X-ray reaching space. Recent discoveries provide some technical evidence that Blackholes has a dramatic effect on the surrounding areas - powerful gamma rays burst, destroy nearby stars, and develop new stars in some areas Preventing it while stopping it in others.


What is Blackhole Structure


The description of the structure of the blackhole is calculated by the general principle of Albert Einstein's relativity. Singularity forms the center of the black hole and it is hidden from the "surface" of the object, event horizon.

Escape velocity inside the event horizon (i.e. the necessary velocity for the substance to avoid the gravitational field of a cosmic object) crosses the speed of light, so that the rays of light can not go into space.

The radius of the event horizon is called Schwarzshild radius after German astronomer Carl Schwarzchild, who predicted the existence of collapsed stellar bodies that emitted no radiation in 1916.

The size of the Schwarzschild radius is in proportion to the mass of the star that collapses. For the blackhole 10 times larger than the Sun, the radius will be 30 km (18.6 miles).

Only the largest stars - having more than three solar masses - become blackholes at the end of their lives. Stars with fewer masses of masses develop in less compressed bodies, either white dwarfs or neutron stars.

What is Blackhole Observability


Blackholes can not be seen directly due to their small size and the fact that they do not emit light. However, they can be "observed" with the effect of their vast gravitational fields on the nearby case.

For example,

if the blackhole is a member of a binary star system, then the material flowing through it with its companion becomes intensely hot and then before entering the event horizon of the blackhole and before disappearing forever, the X Rapidly irradiates RA The binary X-ray system is a blackhole in the component wires of Cygnus X-1. In 1971, the constellation was discovered in cygnus, with a blue supergiant and an invisible partner in this binary, the Sun's mass is 8.7 times which revolves around each other over a period of 5.6 days.

Some blackholes clearly have nonsteller origins. Different astronomers have speculated that large amounts of interstellar gas are collected in the supermassive blackholes at the centers of Kaiser and Galaxies.

The mass of rapidly falling gas in the blackhole is estimated that through nuclear fusion the energy equal to the mass of the mass gets 100 times more energy.

Accordingly, under a gravitational force in a large blackhole, millions or billions of interstellar gas will be responsible for the production of solar mines and huge galactic systems.


Conclusion 



After reading this post, I think you got some idea about blackhole structure and observability. You if really got some knowledge about blackhole please comment below and tell me what you got after reading this post.
Also share this your friends on social media, if you want.

People also ask like these questions:


1. Is a blackhole a hole or a sphere ?


A blackhole is a sphere because everything that goes within its Schwarzschild radius (this is the distance from the center of the black hole to the event horizon) cannot escape its gravity. So  a dark sphere around the infinitely dense center, or singularity, from which nothing can escape.

2. What did Einstein say about black holes?


Answer of this question will  got when you read this post well.

3.What are black holes and how are they created?


For this answer you read this post's introduction heading
