Have YOU thought about astronomy today?

The point of this account is to try to think about astronomy on a daily basis, because life gets in the way of astronomy as a hobby 😔. On this account I only follow accounts related to it, so at least when I log in here I will see news, knowledge, pictures related to it ❣️🔭🌌.

A 16h sur @franceculture.fr Sciences Chrono parle de l'histoire des images astronomiques. Comment l'astronomie s'est-elle construite autour d'un imaginaire visuel qui n'a cessé de marquer les mentalités au point de devenir l'une des sciences les plus populaires ?

Astronomie : la preuve en images
De la première image d’un trou noir aux dessins de la Lune par Galilée, l’histoire des représentations astronomiques est un perpétuel aller-retour entre innovations technologiques et vues d’artistes. ...

Yes, I thought about astronomy. Actually, I just wanted to say that I live in a big city (near Paris 🙄) so light pollution is strong there and we can spot only a few stars (sometimes planet) each night.
