The longest total lunar eclipse of the 21st century toke place, on Friday, July 27th , 2018. The Earth witnessed 3 different phenomenal cases on this night: Bloody moon, lunar eclipse and Mars opposition closer to the earth.
This "Bloody Moon" or lunar eclipse began to appear on July 27th at 8:30 pm and ended at 10:13 pm GMT and the peak of the eclipse was at 9:22 pm GMT. The moon turned deep red or reddish brown during eclipses, instead of going completely dark. That's because some of the sunlight going through Earth's atmosphere was bent around the edge of our planet and had fallen onto the moon's surface. Earth's air also scattered more shorter-wavelength light (in colors such as green or blue); what's left is the longer-wavelength, redder end of the spectrum.
This century's total lunar eclipse occurred on the same day the planet Mars had reached its opposition, when it shined at its best in the night sky. This month, Mars was at its closest to Earth since 2003.
The "bloody moon" continued to emerge completely for one hour and 43 minutes, while partial eclipse was visible to the eye for nearly 4 hours. The longest eclipse in the 20th century had occurred on July 16, 2000, and lasted an hour and 46.4 minutes.
