Question
Astronomers want to make maps of the sky showing sources of X-rays or gamma rays. Explain why those X-rays and gamma rays must be observed from above Earth’s atmosphere
Solution
-
Earth's Atmosphere Absorption: The Earth's atmosphere is very effective at absorbing high-energy electromagnetic radiation such as X-rays and gamma rays. This is beneficial for life on Earth as these rays can be harmful. However, it poses a challenge for astronomers who wish to observe these rays from sources in the universe.
-
Satellite Observatories: To overcome this challenge, astronomers use satellite observatories that are launched into space to observe X-rays and gamma rays. These observatories are positioned above the Earth's atmosphere, allowing them to detect and observe these high-energy rays without any interference.
-
Clearer Observations: Observing X-rays and gamma rays from above the Earth's atmosphere also provides clearer and more accurate observations. The lack of atmospheric interference allows for more precise measurements and detection of these rays.
-
Broad Range of Detection: Finally, observing from above the Earth's atmosphere allows astronomers to detect X-rays and gamma rays from all directions in space. This is crucial for creating comprehensive maps of the sky showing sources of these rays.
In conclusion, to make maps of the sky showing sources of X-rays or gamma rays, these rays must be observed from above Earth’s atmosphere to avoid absorption, achieve clearer observations, and ensure a broad range of detection.
