You may be all hyped up for an epic day of Sunday football; however, there is an epic celestial event occurring as well. Be sure to unglue yourself from the television and get a glimpse of Sunday’s Super Blood Moon! This is the only total lunar eclipse of 2019, so put down your chicken wing and get outside for this celestial phenomenon.
Unlike a solar eclipse, when the moon gets between Earth and the sun, a total lunar eclipse occurs when Earth aligns to block the sun’s light from the moon. That can only happen when the moon is on the opposite side of Earth from the sun. About once a month, a full moon is visible when it nears that far point and shines brightly as Earth covers up most of the sun. But approximately once a year, as the moon travels along its tilted axis, it ends up directly behind Earth and is thrust into near darkness.
At 9:30 p.m. ET on Sunday, the moon will start to creep into the part of Earth’s shadow known as the penumbra. Not much darkening will be visible yet, according to NASA.
By 10:33 p.m. ET, you should see Earth’s shadow start to move across the surface of the moon, growing larger and larger and larger until it completely covers it up.
11:41 p.m. ET will mark the totality of the eclipse, as the moon is fully shaded by Earth. That’s where the “blood” comes in. There’s no violence involved, instead, the term comes froma reddening of moon , as light leaks around the edge of Earth.
