To take for granted that the predatory exploitation of Space is inevitable and essentially good for humankind is a curious axiom.
To deduce from this that astronomers should concede defeat and bow to the new overlords is a remarkable non sequitur.
¡Magnífica noticia para quienes defendemos el medio nocturno de la #contaminaciónlumínica! La asociación @IDADarkSky concede su premio más importante al ingeniero Javier Díaz, más de 30 años liderando la protección del cielo desde el @IAC_Astrofisica.

The lights have turned on at "Alligator Alcatraz", and boy howdy, they're bright! The first image is the 3rd July VIIRS-DNB image of the site; second is an aerial photo made earlier today by pilot and photographer Ralph Arwood.
A 🧵on what's happening here & why it's important:
Find here our new article with insights in how light is propagating in water and the effects of illumination on aquatic ecosystems. I am very proud to be part of the authors team!

It's paper day! Spoiler: artificial light at night is a standard pollutant, and (nearly) all emitted light is polluting or wasted.

Salviamo il cielo e l'ambiente notturno dell'ultima isola di buio della penisola italiana!
Save the night of the last small dark sky zone in the whole Italian peninsula!

This red line might as well be from another planet. We are living the last days of Earth and human civilisation as we had come to know them. A tiny bit of ice left in the Arctic is currently keeping temps from rocketing. Once it goes, things will be simply surreal #ClimateCrisis
Ha ragione @raulclima su https://t.co/hWW4zKhzuQ: 'Occorre re-imparare a vivere con meno luce, anche col buio'. La luce non può essere più simbolo di progresso. Ce lo chiede un pianeta al collasso ambientale. La luce artificiale di notte è un inquinante e come tale va trattato.
#RaulCLima "Re-learning to live with less light, or even with dark, is a principle we should all return to. It is a sign of progress, of awareness, of keeping up with scientific knowledge, of being able to correct environmental errors and long outdated ideas" h/t @elp_stars4all
