Delhi sky-gazers recall thrill to have witnessed 2013 lunar eclipse

NEW DELHI: Avid sky gazers, who had waited with a baited breath, for the first total lunar eclipse of the year enjoyed the spectacle as Moon's white bright glow turned into luminescent orange.

The spectacle of the moon being eclipsed and then turning a moderate to dark red colour was a celestial treat, visible all over the country, including the national capital.

A lunar eclipse occurs when the Moon passes directly behind the Earth into its umbra (shadow). This can occur only when the Sun, Earth, and Moon are aligned exactly, or very closely so, with Earth in the middle. Hence, a lunar eclipse can only occur the night of a full moon. The type and length of an eclipse depend upon the Moon's location relative to its orbital nodes.

The shadow of the Earth can be divided into two distinctive parts - umbra and penumbra. Within the umbra, there is no direct solar radiation. However, as a result of the Sun's large angular size, solar illumination is only partially blocked in the outer portion of Earth's shadow, which is given the name penumbra.

Across the world, the eclipse was visible in the region covering most part of Asia, North America, South America, Australia, Antarctica, the Indian Ocean and the Pacific Ocean.

As the earth came in between the sun and the moon, its shadow first began to sweep across the moon blocking out much of its bright light. The moon's face turned crimson brick red as the shadow descended gently. Many astro-enthusiasts gathered at the Nehru Planetarium to watch the cosmic event.

"I was just mesmerised by the way the lunar surface was completely covered by the earth's shadow," Nisha Gupta, who along with her two children came, said. People had also gathered at the India Gate to watch the eclipse.
