Skywatchers around much of the world are looking forward to a complete lunar eclipse that will be the longest this century.
The "totality" period, when light from the Moon is totally obscured, will last for one hour, 43 minutes.
Scientists across the country will be studying the eclipse as well, as it will provide insights into the condition of the atmosphere above Spain.
The celestial event, where the moon will line up with the Earth and the sun, will be seen across the United Kingdom and other parts of the Eastern hemisphere.
Priyanka Gupta, facilitator from Delhi's Manav Rachna School, showed various lunar eclipse slides and answered the children's queries.
On Tuesday, July 31, Mars will make its closest approach to Earth in 15 years, according to NASA.
The moon travels to a similar position every month, but the tilt of its orbit means it normally passes above or below the Earth's shadow - so most months we have a full moon without an eclipse.
As the space agency further explained, the red planet will be at its brightest from July 27 to July 30, meaning you can likely simply go outside, look up, and get a great view of our neighboring planet with the naked eye.
Dr Brown said: "As the entire eclipse will occur when the moon is fairly close to the horizon, the main thing to ensure is that you have a clear sightline to the south east".
Some of the light from the sun still reaches the moon after it is bent by the earth's atmosphere, he added.
"Totality will last for 103 minutes, making it the longest eclipse of the 21st century!" the Royal Astronomical Society said.
Total lunar eclipses are a rare occurrence.
The long duration of this eclipse was partly because the moon made a near-central passage through Earth´s umbra - the darkest, most central part of the shadow.
On Primrose Hill, north London, would-be-moon admirers broke into a rendition of "Total eclipse of the heart" to lift the soggy mood. But they must clock 72 years to observe the eclipse.
