According to the Science News, Nigeria will experience total lunar eclipse, which would be fully visible in Lagos. Also, timeanddate.com reported on all eclipses worldwide from 1900 to 2100. It noted that there would be total lunar eclipse on July 27, 2018 and January 21, 2019; partial lunar eclipse on July 16/17, 2019; transit mercury eclipse on November 21, 2019; and penumbral lunar eclipse January 10, 2020.
According to Fundamental Astronomy, a lunar eclipse occurs when the Moon passes directly behind Earth and into its shadow. This can occur only when the Sun, Earth, and the Moon are aligned (in syzygy) exactly or very closely, with the planet in between. Hence, a lunar eclipse can occur only on the night of a full moon. The type and length of an eclipse depend on the Moon’s proximity to either node of its orbit.
During a total lunar eclipse, Earth completely blocks direct sunlight from reaching the Moon. The only light reflected from the lunar surface has been refracted by Earth’s atmosphere. This light appears reddish for the same reason that a sunset or sunrise does: the Rayleigh scattering of bluer light. Due to this reddish colour, a totally eclipsed Moon is sometimes called a blood moon.
According to a report by DailyMailUK Online, the lunar event, which takes place on July 27, will be visible to most people living in the Eastern hemisphere and will last for 103 minutes — four minutes short of the longest possible duration an eclipse could last.
The total eclipse is set to last for one hour 43 minutes, but a partial eclipse will be visible for almost four hours.
