Summary: There are some fun astronomical events ahead of us on the calendar, and with a little preparation you can catch them all from home. On Friday, July 27, there is going to be a blood moon, or a lunar eclipse, though not all eclipses make the moon appear red. According to Forbes, the special effect is caused by the indirect light from the sun bouncing through the Earth’s atmosphere and scattering the longer blue and violet wavelengths. All that’s left is that ominous red and orange color.
