Otherworldly space images from a major photography competition
![Meet in a second? Zhang Yanguang This image captures the International Space Station (ISS) passing the solar disk. The solar bottom was captured separately with double stack[an optical filter that isolates specific wavelengths, used to observe solar details]And reveals high -contrast chromospheric details. The imaging sequences were strategically combined during post-processing to preserve both the crisp silhouette of the spaceship and the complex surface characteristics of the sun.

The International Space Station (ISS) scrolls through the sun, a relative close -up of a comet and a tree from another world framed by rotary stars are all pre -selected for the competition of ZWO astronomy photographers of the year of ZWO of this year.
On the photo above is Zhang Yanguang Meeting in a second: A superimposed series of photos of the Iss Silhouetted while it passes directly between the earth and the sun. The large solar panels of the space station, which harvest the energy of this same star, are clearly visible. The photographer used two optical filters to isolate specific wavelengths and highlight the net details of the sun’s wire surface.

In the photo above, a close image of the comet c / 2023 A3 (Tsuchinshan-Atlas) by Gerald Rhemann and Michael Jäger, taken from Namibia. The comets have two tails – one in dust and one of gas – and here they seem to have almost rides due to high solar winds.
The final image, illustrated below, is Dragon trails By Benjamin Barakat, taken to a firmhin forest on the Yemese island of Socotra. A tree of dragon blood (Dracaena Cinnabari) occupies the front of the stage, perfectly framed by the starscape created by merging 300 individual exhibitions.
