Why astronomers hate sunset with brightly glowing clouds,bright moonlit lghts,clear sky with twinkling stars?

It sounds like you're asking ';Why do astronomers hate sunsets with brighly glowing clouds, bright moonlit nights, and clear skies with twinkling stars';?


If that's what you meant to ask (your grammar is a little off), then the answer to the first 2 parts is:


brightly lit skies such as anytime the sun is in the sky or anytime a full or partially full moon is in the sky means that a lot of light pollution (unwanted light) enters their telescopes and makes viewing and studying faint stars and galaxies more difficult.


Just like you would find it hard to see a candle a mile away in the middle of the day.


The third part of your question ';clear sky with twinkling stars'; seems to imply that while there may be no sun, moon, or clouds in the sky the air itself may be turbulent and this can cause the images of faint objects to dance or twinkle, making their study more difficult (its hard to read a book if someone is jiggling it while you're trying).Why astronomers hate sunset with brightly glowing clouds,bright moonlit lghts,clear sky with twinkling stars?
The Full Moon is so bright that its glare interferes with many observations, of meteors, of faint stars and of faint galaxies. Clouds, of course, can wipe out everything. Twinkling is a result of a form of pollution, so astronomers don't enjoy it either. Very dark skies with little wind and no temperature fronts or gradients is the ideal.Why astronomers hate sunset with brightly glowing clouds,bright moonlit lghts,clear sky with twinkling stars?
Don't ask me about the sunsets, but moonlight will outshine the darker objects in the sky and twinkling stars means the atmosphere is not calm to whatevery they are looking at will shimmer like the air above a bbq.
