Multitudes of concentric circular lines swirl across the night sky centered in a silhouetted leafless tree, with faint twilight glow near the horizon.

5hr 50min #circumpolar + 1 hr #CelestialEquator #StarTrails from #Oxfordshire, UK 12/13 Aug '25. It's been a while since I did this particular kind of creative edit. 2,117 images from 2 Canon 1100D cameras were used to make the video. Music by Dave Simpson #StarStaX

Circumpolar, a falta de Perseids.

Fotografía en blanco y negro donde se ve una circumpolar (movimiento de estrellas alrededor de la estrella polar) y en la parte inferior las siluetas de algunas columnas de una construcción abandonada.

A long exposure photo showing star trails circling around Polaris above a forest. The trails form curved lines of varying colors—red, blue, and white—caused by Earth's rotation and each star’s spectral signature. Bare tree branches silhouette the foreground.

Star #Lines
This photo is a stack of hundreds of shots over 2 hours, revealing Earth's rotation.
Each star shows its spectral color, forming a palette dancing around Polaris, the near-static star near the celestial pole.

Ce cliché a été réalisé au pied du dolmen situé dans la forêt de #Ternant en #Côte-d’Or. Photographier une rotation d'étoiles n'y est possible qu'en hiver, quand les arbres sont nus. #nikon #astronomy #astrophotography #landscape #circumpolar #nightsky

Moins 28 degrés Celsius ce matin !

🇨🇦🌡️🥶 Effet vortex ce matin, Moins 28 degrés au thermomètre : j’ai eu du mal à sortir pour aller aux poules parce que la poignée ne tournait plus, et ensuite j’ai eu du mal à rentrer parce que la porte avait collé avec la buée qui a glacé 😂

Fotografía #circumpolar captada por Juan Carlos desde el #CastillodeClavijo en #LaRioja. Este tipo de fotografías muestran la rotación de nuestro planeta alrededor de su eje reflejando el movimiento aparente de las estrellas en el cielo nocturno, mediante la técnica fotográfica de larga exposición.

Map of the arctic polar region titled "With wildfires & warming, tundra now a carbon source". From NOAA 2024 Arctic Report Card. Arctic tundra becoming source of carbon dioxide emissions. Note: When including the impact of increased wildfire activity, the Arctic tundra region has shifted from storing carbon in the soil to becoming a carbon dioxide source. Circumpolar wildfire emissions have averaged 207 million tons of carbon per year since 2003. The Arctic remains a consistent methane source as well. (Image credit: NOAA)
