Sky-watchers see 'blood moon' in total lunar eclipse
Parts of the world, including Argentina, saw a rare celestial event in the first hours of the morning, when the Earth's shadow fell across the moon, turning it orange.
The lunar eclipse unfolded over three hours beginning at about 2 a.m. EDT, when the moon began moving into Earth's shadow. A little more than an hour later, the moon could be seen eclipsed and bathed in an orange, red or brown glow.
The eclipse also was visible from Australia, New Zealand and all of the Americas.
Precise coloring depends primarily on the amount of volcanic ash and other aerosols floating in the atmosphere, SpaceWeather.com reports.
The celestial show was over by over by 5:30 a.m. EDT, NASA said on Twitter.
Eclipses occur two or three times per year when the sun, Earth and the full moon line up so that the moon passes through Earth's shadow.
