The second and final lunar eclipse of the year will occur on the evening of September 7, showcasing a striking red “blood moon” across much of the world. If you were lucky enough to catch a glimpse of March's total lunar eclipse, hold on to that feeling, because September's will not be visible from the Americas.  The totality phase of this eclipse, when the moon is within Earth's shadow and will glow a deep red, will be visible from Asia, central and eastern Africa, and Australia.  Western Europe will catch a glimpse of the event at moonrise; however, it will mostly miss out on the event.  A lunar eclipse occurs when Earth is positioned between the full moon and the sun, causing Earth's shadow to fall on the moon's surface, turning it a rusty red hue.  According to NASA, the totality phase of this year's lunar eclipse is expected to last around one hour and 22 minutes, with the entire eclipse unfolding over roughly three hours and 29 minutes.  The stages of the eclipse will include penumbral, the fainter outer shadow cast by the moon, and umbral, the darker inner shadow, phases.  For US skywatchers, the wait won't be too long, as the next total lunar eclipse visible from America will occur on March 3, 2026.
