According to NASA and the Holcomb Observatory in Indiana, USA, the partial lunar eclipse that will take place on November 19 will be the longest partial lunar eclipse of the century with a duration of about 3 hours 28 minutes 23 seconds much longer than with the longest total lunar eclipse of the century in 2018 with a duration of 1 hour 43 minutes. This is also the longest partial lunar eclipse in 580 years.
The Earth’s shadow will cover 97% of the full moon when the eclipse is at its maximum.
Astronomy lovers in many parts of the Americas, Australia, Europe and Asia can observe this eclipse on November 18 and November 19, the specific time depends on each region.
In Vietnam, the partial lunar eclipse begins at 2:19 p.m., peaks at around 4 p.m. and ends at 5:47 p.m. on November 19 (Hanoi time).
A lunar eclipse is an interesting astronomical phenomenon that occurs when the Earth moves between the Moon and the Sun. At that time, the Moon will be completely obscured by the Earth (total lunar eclipse) or partially (partial lunar eclipse).
During a lunar eclipse, light from the Sun still bends around the blue planet and travels through the atmosphere to reach the Moon. At that time, the Earth’s atmosphere filters out wavelengths shorter than blue and allows only red and orange wavelengths to pass through. When these wavelengths reach the moon, it can cause the planet to appear red.
