The second blood moon of the year is approaching. Early tomorrow morning, October 8, 2014 – a little after 5 am ET — the Earth will move between the sun and the moon and create a full lunar eclipse. The moon will turn a red/orange hue — it will be visible to the naked eye in North America. People on the West Coast of the continent will get the best view.
It’s called the blood moon because of the color it turns when the lunar eclipse happens. When the moon enters the Earth’s shadow it starts getting darker and darker. As KPCC science reporter Sanden Totten describes it: “Then, all of a sudden, it’s fully immersed, and it actually turns red.” The last total lunar eclipse occurred on April 15, 2014. NASA reports that the next will be on April 4, 2015.
