SCIENCE AND TECHNOLOGY

On September 2 Indian Space Research organization launched Aditya 11 satellite which is its first mission to explore the sun.
The prescript will be boosted towards langrange point L1, a strategic location in space which is about 1.5 million km from the Earth.
The spacecraft will continuously observe and monitor the sun and the changing environment which affect the atmosphere of the universe and earth.
Energy generated by nuclear fusion at the sun’s core temperature is around 15 million degrees celsius.
Temperature falls from the center to the outwards.
In the cold the temperature is so high that atoms are broken up into negatively charged electrons and positive recharge ions. This particular state is known as plasma.
Below the sun surface there lies a convection zone where the plasma rises and radiates energy as sunlight reaches the surface.
Right that derives from the Sun is the source of life and living of the entire solar system earth and its atmosphere.
The electric current is created due to the motion of plasma within the sun which creates a magnetic field.
The outermost layer of the sun is known as the corona.
Sun's surface of the photosphere is only about 6000 degrees Celsius hot but the temperature in the sun’s core is a million degrees.
The hot magnetic core of the sun is responsible for the supersonic out flow of plasma that goes to all planets in the solar system and forms background space weather.

Severe space weather can give rise to Geometric storms and create Aurora.
On the other hand it may cause Power grid failures in high altitude regions desert communication GPS navigation and network affect Air traffic and jam radar signals.
They can harm sensitive electronics of satellites and sometimes participate in catastrophic orbital tick hits in the loss of starlink satellites in 2022.
Issues Aditya album mission will explore how magnetic fields results and variation in the sun's ultraviolet radiation which play a crucial role in governing the arts atmosphere and climate change.
It will also observe the flow of energy from the sun's atmosphere to outer space.
By analyzing the X-ray radiation it will seek to understand how violent solar storms are born.

Ian Wilmut, is known as the Pioneer for cloning.
He set off a global discussion about the ethics of cloning when he announced that his team at the University'sRoslin institute for animal biosciences head cloned alarm using A nucleus of a cell from an adult.
Initially this land was referred to as 6LL3.
In the academic paper describing the work the lamp was named dolly after singer Dolly Parto.
