Sun may look calm and beautiful from our earth but it is one of the most ferocious body in our solar system, a body whose mass continuously rises, having millions of nuclear reactions going every second , tingling magnetic lines sun also have strong and constant winds flowing with speed of million miles per hour.
Since it is the only star in our reach to study but it is still very difficult to study its behaviour
So how?
Parker Solar Probe
The answer is Parker solar probe made by NASA which will blast off this year to a long journey of around 4 million miles(6.4 million km) from the earth to the sun.
The temperature of sun which can rise up to 1 million degree Fahrenheit is strong enough to melt anything approaching it. So how will our small probe will withstand this harsh surrounding?
But still the temperature of the solar panels and elements still can go to about 2498 degree Fahrenheit (1370 degree Celsius) so there is necessity to cool down the temperature to safe limits this will done by the advanced thermal regulation system which carry 1 gallon of water as coolant to cool the crucial elements of probe.
Those who do not know about corona, corona is a super hot region of gas and plasma.The solar winds carrying these particles which travel with incredible speeds which are way beyond the orbit of Pluto.
But we will get to know all the answer when our probe will fly through it.The answer is that our little Parker have a advanced carbon-carbon composite heat shield which will help the probe to safeguard its crucial elements behind the shield.It is just like a car radiator.
After reaching into the orbit of sun the probe will go very near to Corona.The high energy particles fly outwards of the star through these region and it is interesting to know that corona is hotter than surface of the star itself .
Nobody knows what causes the winds to accelerate so fast and how they can go so far?
