On July 8th early morning risers saw Mercury near an old Moon low on the eastern horizon. On that date bright planet, faint glow of lunar night side, and sunlit crescent were captured in this predawn skyscape from Tenerifes Teide National Park in the Canary Islands. Never far from the Sun in planet Earths sky, the fleeting inner planet shines near its brightest in the morning twilight scene. Mercury lies just below the zeta star of the constellation Taurus, Zeta Tauri, near the tip of the celestial bulls horn. Of course the Moons ashen glow is earthshine, earthlight reflected from the Moons night side. A description of earthshine, in terms of sunlight reflected by Earths oceans illuminating the Moons dark surface, was written over 500 years ago by Leonardo da Vinci. Waiting for the coming dawn in the foreground are the Teide Observatorys sentinels of the Sun, also known as (large domes left to right) the THEMIS, VTT, and GREGOR solar telescopes.
