Final answer:
To correct the simmering of the atmosphere, also known as bad seeing, astronomers use adaptive optics and carefully select observatory sites. Adaptive optics compensate for atmospheric turbulence in real-time, while optimal site selection includes high altitude and dry conditions away from urban light pollution.
Step-by-step explanation:
When discussing what can be used to correct the simmering of the atmosphere (often referred to as 'bad seeing' by astronomers), we are addressing the issue of atmospheric turbulence distorting the light from celestial objects. One sophisticated method to combat this is adaptive optics, which can correct for the turbulence in real-time, leading to much clearer images. Additionally, astronomers can minimize the effects of the atmosphere by choosing observatory sites with very specific characteristics such as dry conditions, high altitudes, and locations far from city lights to reduce light pollution. Additionally, space-based observations bypass atmospheric issues entirely, but they come with their own set of challenges and expenses.
For example, when employing adaptive optics, adjustable mirrors counteract the atmospheric disturbance by changing shape to compensate for the bending of light caused by the turbulent air. This process significantly enhances the resolution of visible-light or infrared telescopes. Also, situating telescopes in areas with optimal conditions for excellent atmospheric seeing is vital for reducing the negative impact of turbulence on astronomical observations.
