Measuring the brightness of the night sky has become an increasingly important topic in
recent years, as artificial lights and their scattering by the Earth's atmosphere continue …

Artificial lights raise night sky luminance, creating the most visible effect of light pollution—
artificial skyglow. Despite the increasing interest among scientists in fields such as ecology …

Ground-based optical astronomy necessarily involves sensing the light of astronomical
objects along with the contributions of many natural sources ranging from the Earth's …

We present the first World Atlas of the zenith artificial night sky brightness at sea level. Based
on radiance-calibrated high-resolution DMSP satellite data and on accurate modelling of …

Despite constituting a widespread and significant environmental change, understanding of
artificial nighttime skyglow is extremely limited. Until now, published monitoring studies have …

Nightsat is a concept for a satellite system capable of global observation of the location,
extent and brightness of night‐time lights at a spatial resolution suitable for the delineation of …

Proxima b is a terrestrial-mass planet in the habitable zone of Proxima Centauri. Proxima
Centauri's high stellar activity, however, casts doubt on the habitability of Proxima b …

Satellite imagery of night-time lights provided by the US Air Force Defense Meteorological
Satellite Program (DMSP), using the Operational Linescan System (OLS), has been used to …

Globally significant numbers of marine turtles nest on Australian beaches; however, the
human population of Australia is also heavily concentrated around coastal areas. Coastal …

Light pollution at astronomical observatories is one of the main factors to be taken into
account to preserve their scientific productivity and their useful lifetime. Using the Garstang …
