Globe at Night is an international scientific research program that crowdsources measurements of light pollution in the night sky. At set time periods within each year, the project asks people to count the number of stars that they can see from their location and report it to the project's website.
the zodiacal light is still visible, but does not extend halfway to the zenith at dusk or dawn; light pollution domes visible in several directions; clouds are illuminated in the directions of the light sources, dark overhead; surroundings are clearly visible, even at a distance; the Milky Way well above the horizon is still impressive, but ...
Satellite flare, also known as satellite glint, is a satellite pass visible to the naked eye as a brief, bright "flare".It is caused by the reflection toward the Earth below of sunlight incident on satellite surfaces such as solar panels and antennas (e.g., synthetic aperture radar).
Parts of Idaho, South Dakota, Minnesota and Wisconsin may be able to see the lights Friday night. On the East Coast, the aurora might be visible in northern New York and parts of Vermont and New ...
Light pollution is the presence of any unwanted, inappropriate, or excessive artificial lighting. [1] [2] In a descriptive sense, the term light pollution refers to the effects of any poorly implemented lighting sources, during the day or night. Light pollution can be understood not only as a phenomenon resulting from a specific source or kind ...
Some of Drew Carhart’s earliest memories remind him of his love of nature. Not just trees, flowers or birds — but the stars, planets and galaxies visible in the night sky. Fifty years ago ...
The current versions has only one band of observation, that can produce misinterpretations if the light pollution changes from sodium-vapor lamp to LED. [ 8 ] The SQM-L, or "Sky Quality Meter - L," is a model with an additional integrated lens, offering a narrower measurement range of 20° compared to the 84° range of the standard SQM model.
The dark-sky movement is a campaign to reduce light pollution.The advantages of reducing light pollution include an increased number of stars visible at night, reducing the effects of electric lighting on the environment, improving the well-being, [1] health [2] and safety [3] of people and wildlife, [4] and cutting down on energy usage.
