A Star Is a Big Ball of Gas. It is a brownish cloud of glowing gas in a star-filled area of space. Stars are born in a nebula. A nebula is a cloud of gas and dust in outer space, visible in the night sky either as an indistinct bright patch or as a dark silhouette against other luminous matter. Remember: Twinkle, twinkle, little star. How I wonder what you are. (Side note) There is no mystery around who wrote the English words to Twinkle, Twinkle. It was a 23-year-old from Suffolk, England called Jane Taylor. In 1806, she wrote a poem called The Star which was published in a book called Rhymes for the Nursery.Nov 14, 2011 Twinkle twinkle little rip-off: the dark secrets of the world’s most … www.telegraph.co.uk/…/Twinkle–twinkle–little-rip-off-the-dark-secr…
What is a star?
A star is a big ball of gas. It is not star-shaped. Stars give off heat and light.
How is a star made?
Stars are born in nebulas. Nebulas are clouds found in space. They are made of gases and dust.
A star’s color tells us how hot or cold it is. The bluish stars are the hottest ones. The reddish stars are the coolest. But they are still very hot!

Our sun is a yellow star. That makes it one of the cooler stars.
The sun looks very big to us. But it is just a medium-sized star. The sun looks so big because it is close to the Earth.
