You are an astronomer who wants to study a faint star in the process of being born, which gives off most of its faint radiation in the infra-red. Which of the following would NOT be a step you would want to take? a. heat your telescope, so its delicate optics are not cold b. try to have your telescope as high above the layers of water vapor in the Earth's atmosphere as possible c. shield your telescope from the radiation given off by your graduate students d. isolate your telescope in very cold surroundings e. make sure your telescope optics are kept as free of dust as possible

Answer:

a. heat your telescope, so its delicate optics are not cold

Explanation:

If star is just born and giving off  faint radiation in infrared. These radiation would be long range infra red radiation as the star is just born having less surface temperature.

In order to locate the star through telescope, it must be positioned at higher altitudes so that water vapor is minimum. The radiation from other heating objects might alter the light coming through the cosmos. Therefore, it is mandatory to shield the telescope from foreign radiations.

For the same reason mentioned above the telescope must have cold surroundings. Moreover, optics of the telescope must also be kept free from dust and dirt for clear vision.

However, Heating of telescope in order to safe optics from cold must not be done. This would change the wavelength of long range infra red radiations from star and hence, its location.
