The first and only total solar eclipse of 2026 is set to take place today (Wednesday). It presents skywatchers across parts of the Northern Hemisphere with an opportunity to witness the Moon completely cover the Sun. NASA says the path of totality will cross Greenland, Iceland, northern Russia, Spain and a small part of Portugal, while a partial eclipse will also be visible over a larger region. Even with the totality lasting for less than two minutes for most, observers will have a small window of opportunity to witness a rare sky phenomenon.
