This looks like your brain on drugs, but it’s actually a rare solar eclipse from last June in which Venus moved between the Sun and the Earth the way the Moon usually does.
Venus looked like a thinner and thinner crescent until it was perfectly aligned with the Sun, creating a Venusian annular eclipse with a ring of fire.
The Solar Dynamics Observatory imaged the Sun in three colours of UV light, producing data for this image. The next Venusian solar eclipse will occur in 2117, so you’ll have time to enjoy this photo for a while before it’s challenged by something even crazier. [APOD]
