Mysterious dark spot found on Uranus

A mysterious dark spot has appeared in the clouds of Uranus –
something that has never before been seen clearly on the icy
planet. Scientist do not know what makes it dark and why it is
appearing now.

Its more distant neighbor, Neptune, has displayed prominent
dark spots from time to time. They also display a puzzling
range of behaviors, sometimes moving back and forth in latitude,
and sometimes changing shape with time.
