A rare total solar eclipse is set to occur on Wednesday, visible in parts of Europe. This phenomenon happens when the moon blocks the sun's light from reaching certain areas of the Earth. The path of totality will include locations in Iceland, northern Spain, and northeastern Portugal, where observers will experience a brief period of darkness.

For viewers in other areas, including the northern US, a partial eclipse will be visible, with only some of the sun's light blocked from view. Further details about this event are available from the source, including information on viewing locations and the timing of the eclipse.
