That's probably because the picture is looking directly at light sources, which are MUCH brighter than the scattered light in the air. The small amount of scattered light simply won't show up on that picture, even though these 'light domes' can be very large.anorlunda said:
I don't think so.anorlunda said:
I would probably blame the map projection. Polar areas get srteched, so it looks like a huge population centre.anorlunda said:
Kinda. How bright the sky is will depend on how much light is produced and how transparent the sky is. There's weather forecasts for that:anorlunda said:

Light pollution refers to the excessive or inappropriate use of artificial light, which results in the brightening of the night sky and the obstruction of natural starlight. It is caused by the overuse and misdirection of outdoor lighting, such as street lights, building lights, and advertising signs.
Yes, we can see light pollution from space. The excessive and scattered artificial light creates a glow in the atmosphere that is visible from space. This can be seen in satellite images of Earth at night, where urban areas and regions with high levels of light pollution appear much brighter than surrounding areas.
Light pollution has a negative impact on the environment in various ways. It disrupts the natural cycles of plants and animals, affects their behavior and mating patterns, and can even lead to species extinction. It also wastes energy and contributes to the emission of greenhouse gases, which contribute to climate change.
Light pollution can have adverse effects on human health as well. Exposure to excessive artificial light at night can disrupt our circadian rhythm, leading to sleep disorders and other health problems. It can also cause glare and reduce visibility, increasing the risk of accidents and injuries.
There are several ways to reduce light pollution, such as using energy-efficient and properly directed lighting, implementing dark sky-friendly lighting policies, and raising awareness about the issue. Individuals can also make a difference by turning off unnecessary lights and using light-blocking curtains or shades at night.
