This is not a black hole — it’s a shadow.  It’s Earth’s shadow.  Since at least the time of Aristotle, people have noted that Earth's dark shadow on the Moon during a partial lunar eclipse is circular -- although never a whole circle.  Using modern digital technology, though, the images of multiple lunar eclipses can be combined to show Earth's complete shadow.  The featured image compilation by a perseistent astrophotographer is constructed from 22 years of lunar eclipses.  The Moon is not eclipsed every month (moon-th) because the Moon's orbit is slightly tilted relative to Earth's orbit.  Close inspection of some lunar eclipse images shows a faint blue band where  Earth’s atmosphere filters out more red sunlight than blue.  Later this week, a new lunar eclipse will occur and will be best visible in parts of North and South America, Europe, and Africa.
