The instrument used to measure very high temperatures is an optical pyrometer.
It measures temperature based on the thermal radiation (color or brightness) emitted by a hot object, making it suitable for extremely high temperatures where contact sensors cannot be used.

It captures monochromatic images of the Sun — meaning images in one specific color/wavelength, revealing fine details.
Used to study solar phenomena like:

Sunspots
Solar flares
Chromosphere structures
Prominences

It is also called 'Desert Cooler'.
The mechanism of this coolant differs from that of commonly used air conditioning equipment, which is based on the use of vapor-compression and adsorption refrigeration cycles.
Air washers and wet- cooling towers are also based on this principle.

This thermometer is based on Stephen's law.
According to this, the amount of radiation emitted by an object at a high temperature is directly proportional to the fourth power of its absolute temperature.
With its help, the temperature of distant objects (such as the Sun) is measured.

Conduction — Heat transfer through the actual vibration and collision of molecules in a solid or stationary medium. The molecules themselves don’t move far but pass energy to neighboring molecules.
Example: Heat passing through a metal rod.

Convection — Heat transfer by the bulk movement of fluid (liquid or gas) molecules carrying energy from one place to another.
Example: Warm air rising above a heater.

Radiation — Heat transfer through electromagnetic waves without involving molecules or any medium. It can occur even in a vacuum.
Example: Heat from the Sun reaching Earth.
