Imagine a journey that takes you a billion kilometres away from earth, to the edge of the solar system, from where you can look back over your shoulder and see our sun as just another star in the sky. We are not talking about a science fiction movie but the Voyager space mission. On August 20, 1977, the Voyager 2 spacecraft was launched. Close on its heels, the Voyager 1 was launched on September 5, 1977....

Once the tongue makes contact with a prey, the prey gets attached to the sticky tongue like glue....
Everything that is born must die. Not only living beings, but inanimate objects like stars too. The birth of a star The universe has massive clouds of hydrogen floating around. Sometimes, these clouds come together and form very dense and huge balls of hydrogen gas. As the clouds come close, their temperature increases. This is called a proto-star (original star). The increase in temperature triggers off nuclear reactions at the core of the star. Nuclear reactions inside the star occur when the nucleus of two hydrogen atoms fuse to produce a helium atom....
I am sure like my two kids, all of seven and three years, you too may find the cold in Delhi a bit too extreme. It is cold and clammy and some days it is foggy making it dangerous to drive. Some days I would like them to be adequately muffled up in warm winter clothing, while they feel quite comfortable running around in a sweater and shorts! But most days it was grumble, grumble, grumble!...
Jazz originated from the American South in the 18th century as a form of music sung by African slaves employed in the many plantations. Jazz music was influenced by different cultures from a combination of African folk music and rhythms to Caribbean and black American music. Various styles of playing evolved in the 19th and 20th centuries as musicians started to improvise. This was because early musicians did not have formal training in Western classical music and those that did began to introduce European harmonies and forms into Jazz and made the pattern of music uneven....
How many times have all of us heard that the former captain of the Indian cricket team, Kapil Dev, was one of the greatest out-swing bowlers of all times. Indeed!

The term ‘swing’ refers to the movement of the cricket ball in the air after it leaves the bowler’s hand, which takes the ball away from or towards the batsman....
Have you ever climbed a tree and peeked into the nest of a crow or a sparrow? Or looked into that flowerpot where the noisy pigeon decided to lay its eggs? The sight of a mother hen sitting on a bunch of fresh white eggs is great, though most of us see them only when they land on the breakfast table every now and then. Eggs come in different colours. They may be blue, blue-green, yellow, spotted, blotched or white....
Why is it so tough to get ketchup out of the bottle? Why’s it hard for Ketchup to flow? [Illustration by Shinod AP] When you overturn a sauce bottle that has been left untouched for some time, chances are, either the sauce will not come out at all or a gigantic blob will plop down on your plate. Getting ketchup to ‘flow’ out of the bottle can be quite an ordeal....
Among the many architectural marvels of the world, like the leaning tower of Pisa, the whispering gallery at St Paul’s Cathedral at London or the musical pillars of South India, are the astonishing and historical shaking minarets of Ahmedabad, in Gujarat state, India. The minarets are so unique that if one minaret in shaken, the other sympathetically shakes too! Barely a kilometre away from the Ahmedabad city railway station is the Sidi Bashir mosque (Muslim equivalent of a temple) famed for its jhulta minars or shaking minarets (tall tower-like structures, either at the entrance gate or on the four corners)....
Did you know that in India, mango orchards cover roughly 33 percent (1.08 million hectares) of the total area under fruit cultivation? In a hectare of land you can grow thousands of trees. And each tree bears, thousands of fruit! I will leave it to you to calculate how many mangoes the country produces!
