The total lunar eclipse has started! The eclipse's peak, when the moon will enter the Earth's full shadow or umbra, will occur at 3:45 a.m. EDT. The United States is in a prime orbital position and time of day to view the eclipse. Depending on local weather conditions, you will get a spectacular view looking into the sky as the moon's appearance will change from bright orange to blood red to dark brown and perhaps gray. The eclipse is a phenomenon that occurs when the Earth, moon and sun are in perfect alignment, blanketing the moon in the Earth's shadow. The United States will not be able to witness a full lunar eclipse in its entirety again until 2019. Image Credit: NASA #lunareclipse #eclipse #bloodmooneclipse #moon #science #space #nasa #moon
