Only two or three of the nebulæ can be seen without a telescope. The brightest of them all is a faint patch in the star-group Andromeda; and the next brightest is “The Great Nebulæ” in the constellation Orion. Photographs are now taken of the nebula, and we thus see more of their true shapes than could ever be found out by simply gazing at them with our own eyes, which so soon get tired. It used once to be thought that a Nebula was only a very, very far off star-cluster--too far for the largest telescope ever to make us able to see the little separate star-points. But it has now been found that many of the nebulæ are not clusters of stars at all; they are made of shining gases. Gases out there in the distant sky, it is supposed, do not burn away, like gas here on the Earth, because in the sky, far off, there is no air, and nothing can _burn away_ without air. Only when the great masses of gas are very hot they shine with their own heat; and instead of burning away they go on shining, year after year. That is how we see them. Some nebulæ are made partly of gases and partly of stars. And some star-clusters have a good deal of shining gas round about the stars. For a long while nobody knew that there was any bright gas round the stars of the Pleiades cluster. But lately, in some photographs taken of the Pleiades, a curious soft haze has come out round several of the stars, as you may see for yourself in a photograph which tells a truer tale than our eyes can tell. Do you remember hearing that a star is, most likely, a young world not yet cooled? Well, it _may_ be that a nebula is a young sun, or cluster of suns, not yet shaped. These things we cannot know with certainty. We can only say what is believed to be most likely the right explanation. [Illustration: _The Great Nebula in Orion._] Perhaps you have sometimes noticed across the sky at night a band of pale light, wider here, narrower there. In a clear evening, after dark, it may always be seen, and it is called THE MILKY WAY. Stars lie scattered over and around the Milky Way. But beyond and behind all the brighter stars is spread that soft pale band, which in itself is made up of stars--multitudes upon multitudes of distant suns. They are either so very distant or so very small, or perhaps both together, that we cannot see them as separate stars. We only see the general shining of them all. Through a telescope great numbers of stars can be seen in the Milky Way, yet still the band of hazy light always lies beyond. The Milky Way belongs to the same vast Universe of Stars to which our Sun belongs. Indeed, our Sun, with all his planets, is actually _in_ the Milky Way. When you are looking up into the sky, trying to learn about the countless suns of the great Universe, never forget one thing--that “our Father in Heaven” has made them all, and is KING over them all.
