Solar eclipse of August 21, 2017. A total solar eclipse will take place on Monday, August 21, 2017. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth.
Jan 8 2017. If there's anything astronomers love more than space itself, it's predicting future events down to the tiniest calculation. The next solar eclipse isn't set to take place until August, but that hasn't stopped NASA from releasing a more accurate map of the solar eclipse earlier this week. Thanks to new data about the Moon's surface and Earth's own topography, the map gives us a better idea about the exact path the moon's shadow will take as it crosses the face of the planet.
