It's not only our own light pollution that restricts our view. Light pollution is an atmospheric condition, or at least contributes to it - it is such conditions that affect the clarity of an image produced by a telescope, considering the light from stars must make its way through the entire atmosphere to reach our mirrors on the surface, and it's ...

Although the Hubble is a fantastic instrument, it's most certainly not the only source of high-quality deep-sky imagery or data. Every night, there are dozens of active telescopes around the world doing good science and generating beautiful imagery. Adaptive optics has revolutionized terrestrial observing and, as you noted in your question, both aperture and ...

This question really boils down to a more general one: What degree of photometric precision can be achieved by a smartphone camera? To put this question in context, let me give a brief explanation of what is fundamentally different about a scientific image sensor versus a consumer grade sensor. As you would expect, a scientific CCD will usually have much ...

From a physicist point of view it does not help! Pollution is the reflection of light in the atmosphere rather then lights around you. When you step underneath your chimney, you will still see all the reflection of the light in the atmosphere right above you. BUT: You will of course have a better view of the stars, as your eyes don't have to adjust to the ...

Light pollution (as Chris White said in the comments) is less about glare from lights directly beaming into your eyes and more about the atmosphere itself being lit up and essentially drowning out the stars. The contrast between a light polluted sky and stars is too low for our eyes to make the stars out. One way to get around this is to use a filter. If ...
