From space, the Moon's shadow during the solar eclipse of March 9, 2016 appears as a dark spot moving across Earth. During a central eclipse, the Moon's umbra (or antumbra, in the case of an annular eclipse) moves rapidly from west to east across Earth.
The term eclipse is most often used to describe either a solar eclipse, when the Moon's shadow crosses the Earth's surface, or a lunar eclipse, when the Moon moves into the Earth's shadow. However, it can also refer to such events beyond the Earth–Moon system: for example, a planet moving into the shadow cast by one of its moons, a moon ...
The dark area above the center of the solar disk is a sunspot. The antumbra (from the Latin ante "before" and umbra "shadow") is the region from which the occluding body appears entirely within the disc of the light source. An observer in this region experiences an annular eclipse, in which a bright ring is visible around the eclipsing body. If ...
A hybrid solar eclipse occurs because the earth’s surface is curved, sometimes an eclipse can shift between annular and total eclipse as the moon’s shadow moves across the globe.
The total solar eclipse phenomenon known as shadow bands—wiggly, rapidly moving bands of light and dark that can appear on flat, white surfaces about 30 seconds before and after totality—is ...
NOAA's GOES-East weather satellite captured the annular "ring of fire" solar eclipse from space, as the moon cast a large shadow over Earth's surface.
Shadow bands are thin, wavy lines of alternating light and dark that can be seen moving and undulating in parallel on plain-coloured surfaces immediately before and after a total solar eclipse. [1] They are caused by the refraction by Earth's atmospheric turbulence [2] of the solar crescent as it thins to a narrow slit, which increasingly ...
What happens during a solar eclipse? During these cosmic events, the moon passes between the earth and sun, casting a shadow on Earth that blocks the sun's light. There are different types of ...
