Couleurs ou N&B ? Ça dépend tellement du modèle et du contexte qu'il n'y a pas de règle, à mon avis. Dans le cas présent, je préfère la version couleur ! 😊

Un député absent ne peut pas représenter ses électeurs. Je plaide donc pour que la présence aux votes devienne strictement obligatoire. Pour garantir le respect de cette règle, toute absence devrait être sanctionnée par une baisse proportionnelle de leurs émoluments.

There's beauty in imperfection! This new #HubbleFriday view shows the skewed galaxy Arp 184, which belongs to the Atlas of Peculiar Galaxies. Arp 184 earned its spot due to its broad, asymmetrical, star-speckled spiral arm: go.nasa.gov/4jZDB2j #Hubble #Astronomy

An amazing new image from the JWST. We see not one galaxy, but two! In the center, a galaxy in the foreground, whose mass deflects the rays of light from the one behind, forming an Einstein ring, predicted by the theory of General Relativity in 1915. Masses deflect light! #Astronomy

The distance calculated from Cepheids has been cross-correlated with a type Ia supernova in the galaxy. Type Ia supernovae are so bright they are used to measure cosmic distances far beyond the range of the Cepheids, extending measurements of the universe's expansion rate deeper into space.
