The Sky watchers may feast to observe celestial highlights with 5 eclipses this year 2018, 3 solar eclipses and 2 total lunar eclipses event after the first Supermoon 2018 kicked off on January 1st, new year’s day.
On January 31, 2018 a total phase of this lunar eclipse, also known as a Blood Moon, will be visible in large parts of US, northeastern Europe, Russia, Asia, the Indian Ocean, the Pacific, and Australia.
Solar and lunar eclipses are the most spectacular events in the sky. The next lunar eclipse one will be on July 27, 2018: Total eclipse. Visible from South America, Europe, Africa, Asia, Australia.
A total solar eclipse occurs only once every 300 years or so. Because the shadow cast by the Earth is quite a bit larger than the Moon, lunar eclipses are more common than solar eclipses. During a solar eclipse the shadow of the Moon on Earth’s surface is always less than 270 km wide.
What are lunar and solar eclipses?
An eclipse is an event in which a body goes through the shadow of another body. The term eclipse is most often used to describe either a solar eclipse, when the Moon’s shadow crosses the Earth’s surface, or a lunar eclipse, when the Moon moves into the Earth’s shadow. However, it can also refer to such events beyond the Earth–Moon system.
A solar eclipse occurs when the Moon passes in front of the Sun. The type of solar eclipse event depends on the distance of the Moon from the Earth during the event. A total solar eclipse occurs when the Earth intersects the umbra portion of the Moon’s shadow.
A total lunar eclipse has the direct sunlight completely blocked by the earth’s shadow. The only light seen is refracted through the earth’s shadow. The Sun’s distance from Earth is about 400 times the Moon’s distance, and the Sun’s diameter is about 400 times the Moon’s diameter. Because these ratios are approximately the same, the Sun and the Moon as seen from Earth appear to be approximately the same size: about 0.5 degree of arc in angular measure. Image: EarthSky.org
