This week marks the onset of the eclipse season, with an eclipse of the Full Moon on Monday that's not visible in the USA, followed two weeks later by the Solar Eclipse that will be visible either totally or partially throughout the entire US. Hence, a lunar eclipse can occur only the night of a full moon.
There are three types of lunar eclipse: total, partial and penumbral.
A lunar eclipse is either preceded by or followed by solar eclipse, which occurs two weeks on either side.
Solar Eclipses occur when the moon lies directly between the Earth and sun, while lunar eclipses occur when Earth lies directly between the sun and moon.
To say people are excited about this month's total solar eclipse would be an understatement.
Hiroshima Marks 72nd Anniversary of World War II Atomic Bombings
Sunday marks a somber anniversary - the day the USA dropped the atomic bomb on Hiroshima , Japan on August 6, 1945, 72 years ago . At the outbreak of the four-hour uranium bomb thrown by the US B-29 bomber, between 70 and 100,000 people died instantly.
"We're going to be looking at this event with unprecedented eyes", said Alex Young, a solar physicist who is coordinating NASA's education and public outreach.
The moon casts a long shadow over the face of the earth, making daylight turn to twilight within the "path of totality" - or the path along which the sun is completely obscured. If part of the sun still sticks out, it's a partial eclipse. "This will be the first properly visible lunar eclipse this year", said Debiprosad Duari, Director Research and Academic, M P Birla Planetarium.
"They actually happen a couple of times a year".

All that is needed to see the spectacle in the sky is an unclouded view and a pair of eyes. And even if you aren't in position to see it yourself, you can watch the spectacle via a livestream. "That is the light passing through the earth's atmosphere on its way to the moon and is known as the penumbral phase of the eclipse". It requires the moon to fall between the sun and the Earth, so that it seems from our perspective to cover the sun - and that's only possible during a new moon. Due to the early time of the eclipse, it will be harder to see as the sun will only just be setting.
