Shown above is a panorama of the rising shadow of the Earth as observed just after sunset, on May 28, 2017, over an agricultural field in late autumn near Sampacho, Argentina. The curved bluish shadow is hugging the eastern horizon but will climb higher in the east as the Sun dips further below the western horizon. The shadow's pink-colored fringe, known as the Belt of Venus, results from reddened sunlight reflecting off the top portion of the shadow. Even though the Sun has set, the top of the rising shadow is momentarily high enough to be illuminated by sunlight. Look for the Earth's shadow and Belt of Venus wherever there's a clear view of the horizon at sunset (eastern horizon) or sunrise (western horizon).
