Saw my first fully circular 22° halo this morning. (Halos are caused by scattering from ice crystals in form of hexagonal plates.) #AtmosphericOptics #Halo

Some of the most intense and vivid light pillars I've seen on the south side of Fairbanks tonight! I took a few more photos: https://photos.lwpetersen.com/Recent-Photos

Just eight days ago, I gave a popular science talk at @mpi_grav about colorful phenomena in the sky, and now – boom!

Just minutes ago, there were beautiful iridescent clouds (https://en.wikipedia.org/wiki/Cloud_iridescence) here, north of Hanover, Germany.

Here, light is diffracted by tiny droplets in the clouds, creating these typical mother-of-pearl colors.

Yesterday morning felt like one of those quiet bets you make with nature. The night had frozen everything solid, so I suspected there might be low-hanging fog waiting somewhere between the fields and the treelines. As I walked in, part of me was afraid I had already “mist” it — but as the sun crept closer to the horizon, the air began to thicken, soft and silver, like the world taking a slow breath.

Just before sunrise, something unexpected happened. High above the forming fog, an ice cloud lit up in iridescent colours — mostly red, orange, and yellow, with subtle hints of green and blue. Ice crystals at high altitude can refract sunlight much like tiny prisms, creating these fleeting rainbow glows known as irisation. It felt like a quiet scientific miracle happening in real time.

That’s when I saw the leafless tree. Stark, skeletal, patient. And suddenly the composition clicked: a tree seemingly losing its last colours into the sky, like a gentle puff of smoke drifting upward. It’s not my most dramatic image, but there was something special in its simplicity — a moment where winter, light, physics, and imagination lined up just long enough to press the shutter.

Photography, after all, is just another way of studying light and life.

There is currently a halo (22° halo, https://en.wikipedia.org/wiki/22%C2%B0_halo) around the moon.

The ring is created by moonlight refracted by hexagonal, non-oriented ice crystals. These ice prisms are found in high-altitude clouds (cirrus clouds). This type of halo is quite common. Its radius is 22°, which is about 44 full moon diameters.

Regenbogenfragment bei tiefem Sonnenstand heute früh 10 min nach Sonnenaufgang. Der Regen zog in der Entfernung schnell durch, das Regenbogenstück war nur wenige Minuten lang zu sehen

That was a really bright rainbow just before sunset when a heavy shower passed over Wedemark.

La Lune ne change pas, c’est l’air qui joue des tours à sa lumière. Horizon bas, poussières : bonjour reflets rouges.

Pourquoi la lumière de la Lune change-t-elle de couleur ?

En réalité, c'est à cause de nous.

A stunning display of noctilucent clouds over Vallentuna Lake, Sweden, captured on July 10. These night-shining clouds form 80 km above Earth and glow in twilight by reflecting sunlight from beyond the horizon.
