De mora luminis: Roemer's discovery 350 years later
Fabio Falchi, Riccardo Furgoni, Paolo Gattillo +1
350 years from the 1676 announcement of the Roemer's discovery that light propagates with finite speed, we present our observations using eyes with telescopes having similar resolu…
Artificial light at night: a global disruptor of the night-time environment
Salvador Bará, Fabio Falchi
Light pollution is the alteration of the natural levels of darkness by an increased concentration of light particles in the nighttime environment, resulting from human activity. Li…
On the Posch ratio for irradiance in coastal waters and the high seas
Xabier Pérez-Couto, Fabio Falchi, Salvador Bará
The horizontal irradiance at the sea surface is an informative light pollution indicator to study Artificial Light at Night (ALAN) effects on marine biodiversity (e.g.: zooplankton…
A call for scientists to halt the spoiling of the night sky with artificial light and satellites
Fabio Falchi, Salvador Bará, Pierantonio Cinzano +2
Unfettered access to dark night skies is rapidly diminishing, due to light pollution and satellite mega-constellations tracks. Scientists should wake up and do more to stand up to…
Light pollution is skyrocketing
Fabio Falchi, Salvador Bará
Artificial light at night is a pollutant that is rising fast, as demonstrated by Kyba et al. (1) work by analyzing ten of thousands observations by citizen scientists in the last 1…
Light pollution and the concentration of anthropogenic photons in the terrestrial atmosphere
Salvador Bará, Carmen Bao-Varela, Fabio Falchi
Light pollution can be rigorously described in terms of the volume concentration of anthropogenic photons (light quanta) in the terrestrial atmosphere. This formulation, consistent…
