News this week is reverberating around the internet, while orbiting Mercury the Messenger space probe has captured images of something highly unusual, what appears to be a pitch black void, a doorway to the underworld of Mercury.
Eagle eyed NASA enthusiast Scott C Warring (of UFO Sightings Daily) discovered the anomaly within the publicly available data; this particular image is part of the MDIS global mosaic basemap data. The doorway is located adjacent to the Victoria Rupes Cliffs and includes un-naturally straight edges and near perfect corners. Using the adjacent craters for scale the doorway is 5.6km / 3.4 mile wide, if this is the garage door how big is the car?
Taking a closer look at the Mercury void image there appears to be an unusual distortion around the edges, there is no shadow to suggest shape or dimension. Closer inspection shows the completely black shape is a lack of anything more than it is an object.
