To mitigate contamination, astronomers employ various strategies:
Instrument Design: Designing instruments with better shielding against noise and implementing advanced optics to minimize distortions. Observational Techniques: Using techniques like adaptive optics to correct for atmospheric effects and choosing observation sites with minimal light pollution. Data Processing: Implementing sophisticated algorithms to identify and remove contaminants from the data. Multifrequency Observations: Observing the same region in different wavelengths to separate the target signal from contaminants.
