This was an unusual type of solar eclipse. It is the Earth's Moon that eclipses the Sun. Venus took a turn in 2012 The phase of Venus became thinner as it became better aligned with the Sun. The phase of Venus dropped to zero as the alignment became perfect. Our parent star was crossed by the dark spot of Venus. The situation could be labeled a Venusian eclipse with a large ring of fire. The Sun was imaged in three colors of ultraviolet light by the Earth-orbiting Solar Dynamics Observatory, with the dark region to the right corresponding to a hole. As Venus continued in its path, a crescent phase appeared again. The next Venusian transit will take place in 2117

Explanation: Yes, but can you see the lion? A deep exposure shows the famous dark indentation that looks like a horse's head, visible just left and below center, and known unsurprisingly as the Horsehead Nebula. The Horsehead Nebula (Barnard 33) is part of a vast complex of dark absorbing dust and bright glowing gas. To bring out details of the Horsehead's pasture, an astrophotographer artistically combined light accumulated for over 20 hours in hydrogen (orange), oxygen (blue), and sulfur (green). The resulting spectacular picture captured from Raachine, Lebanon, details an intricate tapestry of gaseous wisps and dust-laden filaments that were created and sculpted over eons by stellar winds and ancient supernovas. The featured composition brings up another pareidolic animal icon -- that of a lion's head -- in the expansive orange colored gas above the horse's head. The Flame Nebula is visible just to the left of the Horsehead. The Horsehead Nebula lies 1,500 light years distant towards the constellation of Orion.
