Night Sky Reflections from the Worlds Largest Mirror
21.10.2019

What's being reflected in the world's largest mirror? Stars, galaxies, and a planet.

Inside the arch is another galaxy -- the neighboring Large Magellanic Cloud (LMC).

Near perigee, the closest point in its almost moonthly orbit, a Full Moon rose as the Sun set on August 1. Its brighter than average lunar disk was captured in this dramatic moonrise sequence over dense cloud banks along the eastern horizon from Ragusa, Sicily.

Planetary Nebula Abell 7
22.01.2026

Very faint planetary nebula Abell 7 is about 1,800 light-years distant. It lies just south of Orion in planet Earth's skies toward the constellation Lepus, The Hare. Posing with scattered Milky Way stars, its generally simple spherical shape about 8 light-years in diameter is revealed in this deep telescopic image.
