Text A. WHAT IS A STAR?

A star is a body of luminous gas, like the sun. But as stars are much farther away from the earth than the sun, they appear to be only small points of twinkling light. With the naked eye it is possible to see about 2,000 stars at any one time or place but with the most powerful telescope over 1,000 million stars are visible. Although light travels at 186,000 miles a second, the light from the stars takes many years to reach the earth.

Stars are not fixed in space, but are traveling in different directions at different speeds. Seen from the earth, these movements appear to be so small that groups of stars, or constellations, seem to have a permanent relationship. The star patterns we see in the sky are almost the same as those seen by our ancestors hundreds, or even thousands of years ago.

The sizes of stars vary tremendously, from less than the diameter of the sun to thousands of times its size. Most stars appear white when looked at with the naked eye, but some are bluish-white, yellow, orange and red. The varied colours are due to differences in surface temperature. The brilliant, white stars are hottest with surface temperatures of several hundred thousand degrees. The less brilliant, orange and red stars have surface temperatures of about 2, 000 degrees.

There are exceptions, however. The red giant, Betelgeux, in the constellation (or group) of Orion, appears to be brilliant because of its size. Its diameter is 250 million miles, which is greater than the diameter of the earth's orbit round the sun.

Shooting stars which are sometimes seen moving across the night sky for a few seconds are really meteors. These small particles flare up as they strike the earth's atmosphere and usually burn out.

Text B. SPACE EXPLORATION

 

Exploration of outer space in the 20th century has produced discoveries and inventions that will forever change the way people live, learn and interact.

The dream of space travel is as old as history but it was in the 20th century when the dream became reality. The first aeroplane (airplane) flight occurred in 1903 and in 1926 the first liquid-fuelled rocket was launched that traveled 200 feet.

After World War II, the superpower opposition between the USA and the Soviet Union stimulated rocket research and development. Both nations realized that large rockets can be used to attack an enemy from thousands of miles away and that satellites put into orbit around the Earth by rockets could transmit messages.

The Soviet launch of sputnik, the first man-made object to overcome gravity, began the space age. The Soviet Union soon achieved many other firsts. In 1961, the Soviet Union put the first man, Yuri Gagarin, into space. The first long space flights, a woman in space and space walk were all Soviet achievements. The Soviet Union made great progress in the peaceful application of space exploration. In its Salyut 6, it investigated such vital matters as the causes of cancer, since cells are studied in gravity-free space. The construction of metals that can resist gravity has resulted in tools of incredible hardness; improved seeds have been developed in Salyut.

In the early 1960s the United States organized the Apollo space program. This research program concentrated on landing a man on the moon. Two Americans, Neil Armstrong and Edwin Aldrin, walked on the lunar surface in July 1969.

Since the first moon landing many nations have developed programs of space exploration. A network communication satellites made world-wide television and telephone service possible. Space shuttles allowed regular trips between the Earth and space. Scientific satellites were put in the Earth's orbit. Voyages to Venus were made by the Soviet spaceships, voyages to Mars, Jupiter and Saturn - by the American spaceships.

This scientific progress has since resulted in hundreds of benefits for mankind, from the weather satellites whose information we see in our daily newspapers and on TV, to determining from outer space where fish is, where natural resources are hidden in the earth and in discovering areas which are becoming deserts.

 

========================= VOCABULARY ===================

 

exploration, n
outer space
occur, v
to launch a rocket
superpower opposition
satellite, n
man-made object
overcome, v
investigate, v
to resist gravity
