A Lunar Eclipse (Chandra Grahan) is when one can't see the moon at night because its position is relative to the sun and earth ensures that light doesn't fall on the part of it we can see.

The moon gives off no light and is only visible because it reflects the light of the sun. We only see the part where light falls and thus as the earth and moon move through their orbits and different amounts of light falls on the moon, we see different phases of the moon.

When a lunar eclipse (Chandra Grahan) occurs, the Earth comes between the sun and moon, preventing light from falling on the moon.
When this happens, the moon appears to glow red and is thus called the blood moon.

The red colour is because of the way light travels through the Earth's atmosphere. Sunlight is made of several colours and they all have different wavelengths. Depending on the way they travel through our atmosphere, we see different colours. That's why the sun and sky have different colours during sunrise and sunset. Blues and purples have shorter wavelengths and scatter in our atmosphere, giving the sky its inky colour, but reds and oranges have the highest wavelengths and pass through our atmosphere before it is bent or refracted around Earth, hitting the surface of the Moon and making it red.

The upcoming lunar eclipse (Chandra Grahan) on 27-28 July 2018 will be the longest eclipse of the 21st century. This is because the moon is at the furthest point in its orbit and will take 3:55 hours crossing the Earth's dark umbral shadow.
This year's eclipse is when the Earth will be close to Mars. Mars should be quite visible throughout July and August and visible in all its crimson glory close to the blood moon. This celestial sight should be a treat to see.
It’s safe to observe a lunar eclipse (Chandra Grahan) with the naked eye. Lunar eclipses are rare, an area will get 3 in a year at the most and with such a spectacular celestial line up this time, one should definitely find time to observe it.
