[1] Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2019 January 20 A Total Lunar Eclipse Video Video Credit & Copyright: Jun Ho Oh (KAIST [2] , HuboLab [3] ), Kwon O Chul (TWAN [4] ), Jeong ByoungJun [5] (RainbowAstro) Explanation: Tonight a bright full Moon will fade to red. Tonight's moon [6] will be particularly bright because it is reaching its fully lit phase when it is relatively close to the Earth in its elliptical orbit [7] . In fact, by some measures of size and brightness, tonight's full Moon is designated a supermoon [8] , although perhaps the "super" is overstated [9] because it will be only a few percent larger and brighter than the average full Moon. However, our Moon will fade to a dim red [10] because it will also undergo a total lunar eclipse [11] -- an episode when the Moon becomes completely engulfed in Earth's shadow. The faint red [12] color results from blue sunlight being more strongly scattered away by the Earth's atmosphere. A January full moon, like the one visible tonight, is referred to as a Wolf Moon [13] in some cultures. Tonight's supermoon total eclipse [14] will last over an hour and be best visible [15] from North [16] and South America [17] after sunset. The featured time-lapse video [18] shows the last total lunar eclipse [19] -- which occurred in 2018 July. The next total lunar eclipse [20] will occur only in 2021 May.
