Here's what to expect during each stage of the Aug. 27-28 partial lunar eclipse, as our planet's colossal shadow swallows 96% of the moon's surface for billions on the night side of Earth.
August's lunar eclipse is the closing act of a dramatic two-part show, the opening act of which began on Aug. 12 as the moon covered the face of the sun to trigger a spectacular total solar eclipse over parts of Greenland, Iceland and Spain.
Eclipses always come in pairs, but the stages to be expected during a lunar eclipse are staggeringly different from its solar equivalent. One major bonus of a lunar eclipse is that each stage unfolds simultaneously for everyone on the night side of Earth, where the lunar disk is above the horizon. However, the local time for each stage will differ based on your location.
Lunar eclipses are also completely safe to view with the naked eye, or even through a pair of binoculars of a telescope, which will offer a magnified view of the moon as Earth's shadow sweeps across its cratered landscape.
Earth's shadow is divided into two concentric cones that are only visible during the brief window of a lunar eclipse. The outer penumbral cone casts a soft, wide shadow, while the inner umbra reveals the distinct curve of Earth's silhouette.
The eclipse officially begins at 9:23 p.m. EDT on Aug. 27 (0123GMT on Aug. 28), as Earth's outer penumbral shadow begins to cover the moon's surface, according to TimeandDate.com.
Darkening of the lunar disk during this stage is incredibly subtle, becoming most apparent in the moments before Earth's inner shadow appears to transform August's "Sturgeon Moon", which is named for the time of year when the large fish were easily caught in North America.
Earth's inner umbral shadow will take its first "bite" out of the moon at 10:33 EDT on Aug. 27 (0233 GMT on Aug. 28), announcing the start of the partial phase of today's deep lunar eclipse.
