Question:- Like everything in Minecraft game, an Astronomer started thinking what will happen if our Sun would have been a square of similar luminosity.

a. If the Sun was a cube, what would be its surface temperature?

b. In what interval, does its magnitude lie as seen from the Earth?

Hint: The volume for Cube Sun remains the same as usual.

neutron stars are some of the densest objects in universe. The form during supernova explosions and very small compared to other astronomical objects you can assume 5*10¹⁷kg/m³ as the average density of a neutron star The earth has a total mass of about 5.97*10²⁴kg what would be the diameter of the earth if it had the density of a neutron star

Why is the orbit of the telescope stable nonetheless? What otherforces need to be considered?

Why is it important to position the JWST behind the Earth?

The electromagnetic spectrum contains various types of radiation with different properties. The James Webb Space Telescope is not like an optical telescope at home and does not capture visible light; instead, it observes the sky in the infrared spectrum.

Explain what infrared radiation is and answer the following questions: How is infrared radiation different from visible light? Why does the JWST observe infrared light, and what are the scientific advantages for astronomers?
