Answer:
<em>Infrared telescope and camera</em>
<em></em>
Explanation:
An infrared telescope uses infrared light to detect celestial bodies. The infrared radiation is one of the known forms of electromagnetic radiation. Infrared radiation is given off by a body possessing some form of heat. All bodies above the absolute zero temperature in the universe radiates some form of heat, which can then be detected by an infrared telescope, and infrared radiation can be used to study or look into a system that is void of detectable visible light.
Stars are celestial bodies that are constantly radiating heat. In order to see a clearer picture of the these bodies, <em>Infrared images is better used, since they are able to penetrate the surrounding clouds of dust,</em> and have located many more stellar components than any other types of telescope, especially in dusty regions of star clusters like the Trapezium cluster.
Answer:
The light radiated from the Sun's surface reaches Earth in about 8 minutes. However, the energy of this light was released by fusion in the Sun's core about several hundred thousand years ago.
Explanation:
Nucleosynthesis is the fusion of lighter elements into heavier elements. For the Sun the main mechanism of fusion is the proton - proton chain, in which two hydrogen atoms fuse into helium, in the course of the fusion photons are created.
When those photons start their travel from the core to the surface of the star, they will interact with different atoms in the whole way (the main free path).
More precisely, when a photon¹ is absorbed by an electron in an atom of a particular element, the electron will get to a higher state. When it comes back to the ground state, a photon will be emitted again.
The process described above is repeating multiple times for every photon until they reach the Sun surface.
The whole process can take about several hundred thousand of years.

¹Photon: Particle that constitutes light.
Explanation:
The pascal (symbol: Pa) is the SI derived unit of pressure used to quantify internal pressure, stress, Young's modulus and ultimate tensile strength. It is defined as one newton per square metre. It is named after the French polymath Blaise Pascal
