Reflector Telescope

When Galileo turned his newly invented telescope to the sky, a whole new vision swam into view. He could see ten times as many stars as any man had ever before seen. The Milky Way now appeared, not as a nebulous mass, but as a kaleidoscope of countless stars, great and small. The moon’s surface was transformed before his eyes from lustrous porcelain into a mosaic of mountains, craters, and waterless seas. A few months later, he spotted four of the moons of Jupiter. Then he saw the beautiful rings of Saturn.

Now, after nearly four hundred years of intensive scrutiny, our knowledge of the universe has increased dramatically. Different types of stars, such as red giants, white dwarfs, and pulsars, have been identified. Recently, quasars—enigmatic objects that emit prodigious amounts of energy—have been detected in the outer reaches of space. And mysterious black holes—like unimaginably powerful cosmic whirlpools—are now believed to lurk unseen in many galaxies. Powerful optical telescopes enable astronomers to peer far into space and thereby in effect journey billions of years back in time, to the very edge of the visible universe. Vast array of stars and galaxies have been discovered, some so distant that their light is calculated to have taken more than 15 billion years to reach the human earth.

Though it is impossible to correct all known aberrations in man-made lenses, they can be effectively masked by the combination of several precision lenses. These may be cemented together with Canada balsam, a resin from the North American balsam fir tree. Some lenses are coated to prevent “ghosting” or reflections from forming. Complex systems are also employed in telescopes, binoculars and microscopes. These apply the principle of a convex objective lens for casting an image in the microscope or telescope tube, which is not shown on any screen but is made to fall within the focal length of an eyepiece. The image formed there is then viewed through the eyepiece, giving a magnified view of the object.

The inverted narrate of the image does not really matter in the microscope. (The slide being viewed can be turned upside down first.) But no ship’s captain would be happy with his binoculars or telescope if his next port of call appeared inverted. For this reason a correcting set of lenses or prisms is introduced between the objective lens and the eyepiece to rectify that problem. Lens making by intelligent men involves a thorough knowledge of optics, refraction-of-light mathematical formulas and then patient skill, learned and accumulated over many years of training by another skilled in these arts.

Observatory telescopes today are virtual behemoths compared to Galileo’s 1 3/4-inch-diameter (4.4 cm) models. His primitive devices were refracting telescopes. A large convex lens on one end formed the image and a small concave lens at the other end, later modified to be also convex, magnified the image. Remarkably, his instrument could magnify objects up to 33 times, allowing him to view such distant wonders as Jupiter’s four moons and Venus’ moon-shaped phases.
Today’s reflecting telescopes use immense, bowl-shaped mirrors (up to 236 inches [600 cm] across!) to collect light from faraway heavenly bodies. They are thus able to detect objects ten million times fainter than those that can be seen with the naked eye. Why, it is claimed that one telescope in Australia could detect a candle flame a thousand miles (1,600 km) away! Interestingly, though, astronomers today still run into the same problem Galileo faced. He noticed that when magnified the stars increased in number but not in size. Galileo reckoned that the stars must be incredibly distant to remain mere points of light under magnification.

The Role of Telescopes

In 1931 the electron microscope was invented. By aiming a stream of electrons at an object, a visual image can be produced in which objects are magnified about a million times. There is one serious drawback: It cannot be used to study living specimens. A new device, however, which combines the optical microscope with television cameras and computer memory, now makes it possible for scientists actually to observe the biological activity of living cells! Telescopes and microscopes are thus potent tools. They have given man a startling insight into the world—and universe—in which he lives.

Yes, telescopes are making great impact in the process of humans’ gaining knowledge.
