Question

multiple choice question
astronomers at nasa use telescopes that are sensitive to all different types of electromagnetic radiation. sometimes the telescopes have to be placed in space rather than on earth for them to work properly. what type of telescope would need to be placed in space so it doesnt measure heat in surrounding objects on earth?
infrared
x - ray
gamma ray
ultraviolet

Explanation:

Infrared telescopes detect infrared radiation which is related to heat. Objects on Earth emit infrared (heat). Placing an infrared telescope in space gets it away from Earth - based heat sources (like the atmosphere and ground objects emitting infrared) so it can accurately measure the infrared from celestial objects. X - ray, gamma - ray, and ultraviolet telescopes are more about detecting high - energy or specific non - heat related electromagnetic radiations. X - rays and gamma - rays are high - energy photons, and ultraviolet is a shorter - wavelength (higher - energy than visible light but not heat - related in the context of Earth's heat interference here) part of the electromagnetic spectrum.

Answer:

infrared
