Sun - The Ball of Fire
Mysterious Sun:
Electromagnetic winds emmited from Sun are solar winds. Solar winds consists of protons and electrons, when these protons and electrons interact with Earth's magnetic field sky get lit up by different colors. The solar winds are emmited by solar holes in sun, as these solar holes are less dense than other parts of Sun, they provide path to allow the wind outwards to surface of Sun. These winds are thrown out by such a huge force that they can travel very long distances, even reaching to Earth. These winds can have speed up to 1000 Km/sec.

Even though we know Sun from centuries,
there are many mysteries of Sun remained unsolved. Most popular mystery is
regarding Corona of Sun. Corona is outer layer of Sun's atmosphere. Corona is
hotter than the inner layer Chromosphere. Sun's visible surface
Photosphere has temperature 5800°C. Outer layer of Photosphere is
Chromosphere. Temperature of Chromosphere is estimated to be 4000°C. But
astonishing fact is that Corona (outermost
layer of Sun) is 3 Million ℃. This is not possible if Heat Transfer laws are to be considered.
To study about Sun in detail NASA sent a probe in 2018, ISRO will send
Aaditya L1 probe to Langlargian L1 point from where Aaditya L1 will study the
properties of Sun.
