Watching the summer night sky is a great fun. There is hardly any one who hasn't taken a look in wonder gazing the starts. Kids across the ages have gazed at the moon and stars with a timeless sense of awe and wonder. No wonder, for quite a few, stargazing is a passion. And even those who don't think it to be fascinating enough, a laid back evening under the starry canopy, with the soothing summer breeze stoking all over, would not be a bad. open session of under the clear
It's amazing to see a star studded night sky. Specially in summer, when you can indulge in this without being frozen or catching an awful cold. Those countless bluish-white twinklers are, as if, sprayed across the black canopy up above. The longer you keep gazing at them, the more of them just bloom out of the black background.
True, the night sky does not show the Sun. But it offers a far greater view. The view of the Universe. The universe that comprises billions and billions of such suns and their families. Our solar system, to which the Earth belongs, is also a tiny member of this universe. And like those twinklers it is tucked away, up there against the vast blackness.
At the outset, all of them appear more or less the same, though they are not.
A little keener gaze, and you can make the difference. Some are twinkling with a glow, some are fader, yet, stay steady. Some are off white, while some sport a milky white shade. Still, many of them blink with a bluish tinge.
Some are closer, while some are way far. Some of them are stars, some planets, and, moons or satellites. The shooting ones are mostly meteors, while those with a trailing light are mostly comets. Scientists or astronomers have made us familiar with quite a few of them. Yet, there are countless of them still strangers.
In fact, the star studded night skies are a window to the limitless world of the unknowns.
However, what we see there with naked eyes reveals only a tip of the boundless universe. And there are just too many of those stars and comets and planets and moons and meteors that we can imagine.
Isn't it a wonder that all those countless heavenly bodies, seemingly stuck out against the vast blackness, are very mobile. Moving away or towards us over a span of long time. Each one is following a certain direction and speed throughout their motion. And while in motion they change their sizes and shapes and follow a life cycle. Just like ours. They are born, grow up and mature. And finally die and go into oblivion. Only the cycle is spread over a huge of span of time and space. And as we see them they are caught in some phase of their life cycle. Unfortunately, we are born, grow, mature, and die out.
There are so many of them that it will not be wise to try to pick them up one by one. Instead, it is easier to identify them as a group or, collection. The collection of stars is called a constellation. What are they and how do they look like?
