Η δική μου προσπάθεια καταγραφής της μερικής έκλειψης του Ήλιου σήμερα απο την πόλη της Κηφισιάς.

Planet Parade in June 2022 Simultaneous images were combined to construct this atmospheric predawn skyscape. The cooperative astro-panorama captures the 5 planets of the Solar System, just before sunrise on June 25. That clear morning found innermost planet Mercury close to the horizon but just visible against the twilight, below and left of brilliant Venus. Along with the waning crescent Moon, the other bright naked-eye planets, Mars, Jupiter, and Saturn lie near the ecliptic, arcing up and to the right across the wide field of view. These five planets aligned was back in 2004 and it won't happen again until 2040.

Almost every object in the above photograph is a galaxy. The Coma Cluster of Galaxies pictured here is one of the densest clusters known - it contains thousands of galaxies. Each of these galaxies houses billions of stars - just as our own Milky Way Galaxy does. Although nearby when compared to most other clusters, light from the Coma Cluster still takes hundreds of millions of years to reach us. In fact, the Coma Cluster is so big it takes light millions of years just to go from one side to the other. Most galaxies in Coma and other clusters are ellipticals, while most galaxies outside of clusters are spirals.
