If there is no medium in space for sound to propagate then how NASA captures sounds of planets?

Question

Answer

yeah space do not have any sound as it not have any medium to propagate but planets have their own atmosphere means medium for propagation.so we can hear sound of planets but not of space if still have doubt then ask plz

Answer

I had asked same question to my sir , he had not answered me clearly . I have to use Google . see on Google , perhaps there is answer.

Answer

Introduction:
In space, sound cannot propagate as there is no medium for it to travel through. However, NASA is able to capture and study the sounds of planets using various techniques that do not rely on the traditional propagation of sound waves.

Electromagnetic Waves:
- NASA primarily uses electromagnetic waves to capture and study the sounds of planets. Electromagnetic waves, such as radio waves, can travel through the vacuum of space without the need for a medium.
- Planets emit various electromagnetic signals, including radio waves, which can be detected and converted into audible sounds for scientific analysis.

Radio Waves Detection:
- NASA's Deep Space Network (DSN) consists of a network of large radio antennas located around the world. These antennas receive and transmit radio signals to communicate with spacecraft and capture data from distant planets.
- The antennas in the DSN can detect and receive weak radio signals emitted by planets.
- These signals are then amplified and processed to convert them into audible sounds that can be listened to and studied by scientists.

Conversion to Audible Sounds:
- Once the radio signals are received and amplified, they are converted into audible sounds using various techniques.
- The signals are typically converted into audio frequencies that fall within the range of human hearing.
- Scientists can then listen to these sounds and analyze the patterns, frequencies, and other characteristics to gain insights into the planetary environment and processes.

Visualization:
- In addition to converting the signals into audible sounds, NASA often visualizes the captured data in the form of spectrograms or other graphical representations.
- Spectrograms display the frequency (y-axis) and time (x-axis) of the captured signals, allowing scientists to study the patterns and changes over time.

Conclusion:
While sound cannot propagate in the vacuum of space, NASA utilizes electromagnetic waves to capture and study the sounds of planets. Through the detection of radio signals emitted by planets and their conversion into audible sounds, scientists can gain valuable insights into the planetary environments and processes. Additionally, visualizations such as spectrograms provide further analysis and understanding of the captured data.
