Spying a Rare 'Ring of Fire' Around Venus at Inferior Conjunction
Amazing things happen in the day-to-day sky, often unseen and unwitnessed in our normal routine. Just such a 'non-event' happened this week, when Venus reached inferior conjunction between the Earth and the Sun on its race from the dusk to the dawn sky. And what's more amazing, is the fact that some skilled observers followed this passage and caught sight of Venus as a tiny blazing 'ring of fire' silhouetted against the sky.
