It was a nice CLEO Europe
#cleoeurope
Thanks @jiaqijqli.bsky.social and Andrei Ermolaev for the pictures

It was a real delight to work with @optica-opn.org on a photo essay describing our university's historical optics instruments collection. The article (for Optica members) is here www.optica-opn.org/home/article... but the photos are public on Flickr here: www.flickr.com/photos/13104...
Preserving Optics Heritage at the University of Franche-Comté
<p>An effort to safeguard the legacy of optics includes a museum of historical instruments, some dating to 1845.</p>

Preparing my 2025 Day of Light outreach lectures, I bought a glass sphere and made a rainbow. But I saw some odd things, and so here’s a thread with some photos and raytracing pictures. There may well be mistakes so tell me and I'll fix them. First the basic setup showing the primary bow.

Arp 321.
a compact group of five galaxies located in the constellation Hydra. It's a fascinating object for astronomers because these galaxies are in close proximity and interacting with each other.

This Hubble image captures Arp 321, a compact group of interacting galaxies. The galaxies display distorted structures and bright star formation regions, evidence of their gravitational dance. The dominant galaxies show prominent spiral arms and bright cores.

2025 vient d'être déclarée année de la quantique par l'ONU ! L’occasion rêvée de découvrir les ressources gratuites qu'on a conçues. Si vous aimez, partagez largement. Après tout, ce n'est pas tous les jours qu'on inaugure une année quantique ! vulgarisation.fr/projet/annee...

C'est beau une comète, et cette photo prise en 2001 particulièrement !

Do yourself a favour and open up this photo.

Indulge in the absurd beauty of comets.

This is Comet C/2021 A1 Leonard, photographed by Michael Jäger in 2021. The tail, millions of km long, shows a region of greater density from when part of the comet nucleus disintegrated about 10 days before.

If you put apertures of different shapes in the path of a plane wave, you get different diffraction patterns. And with a bit of experience you can say a lot about the aperture shape just by looking at the diffraction pattern.

Le télescope spatial Hubble vient de finir une carte hallucinante de la galaxie d'Andromède: 2,5 milliards de pixels, on y voit 200 millions d'étoiles, la galaxie en compte des centaines de milliards!

Vous pouvez vous y balader ici: www.esa.int/Science_Expl...

Bon voyage!

Delighted to announce that Andrei Ermolaev's PhD work was selected for Optics in 2024 by @opnmagazine.bsky.social The idea is to algorithmically analyse the term by term contributions that make a PDE sum to zero so as to determine the dominant physics. Simple! www.optica-opn.org/home/article... 🧪💡

Des chercheurs de Google ont utilisé des données provenant de 40 millions de téléphones portables pour cartographier en temps réel les conditions qui règnent dans l’ionosphère.

Objectif: améliorer la navigation par satellite et aider l'étude de l’ionosphère.🧪

Source www.nature.com/articles/d41...
Schéma expliquant la méthode pour étudier l'ionosphère en temps réel avec des téléphones portables. Les signaux satellites peuvent être utilisés pour cartographier le contenu en électrons de l’ionosphère. C'est possible parce que les ondes radio sont ralenties par ces électrons, et la durée du retard est directement proportionnelle au nombre total d’électrons entre le récepteur et le satellite. En transmettant des signaux à deux fréquences ou plus, le nombre total d’électrons ionosphériques le long du trajet d’un signal peut être calculé.

Infrared image of Jupiter by JWST.
🔭 🧪
This image was created from a composite of several images from Webb. Visible auroras extend to high altitudes above both the northern and southern poles of Jupiter. The auroras shine in a filter that is mapped to redder colors, which also highlights light reflected from lower clouds and upper hazes. A different filter, mapped to yellows and greens, shows hazes swirling around the northern and southern poles. A third filter, mapped to blues, showcases light that is reflected from a deeper main cloud. The Great Red Spot, a famous storm so big it could swallow Earth, appears white in these views, as do other clouds, because they are reflecting a lot of sunlight.
