1. T. Scientists say it could take at least 1,500 years before humans make contact with species of aliens, or for them to communicate with or find us.
2. F. Astronomers from Cornell University in the USA combined two existing theories about the possibility of life existing on other planets to form a new equation.
3. F
4. T. The other is the principle, which suggests that because there is life on Earth, it will typically exist on Earth-like planets throughout the universe.
5. F. According to Solomonides, extraterrestrials could have received signals from Earth.
6. T . He said they would need to decode the light waves into sounds and analyze 3,000 human languages to understand any messages.
7. T. He said that signals from Earth have only reached about 8,500 stars
8. F. If we stop listening or looking, we may miss the signals, so we should keep looking.
Our sun is actually an orange, dwarf star. Although it is not nearly the ....hottest ....(hot) star known, its surface temperature is about 10,000'F and that of its interior is thought to be in the range of 20,000,000'F. We ......commonly ..... (common) think of the sun as burning, yet it's too hot to burn and is composed of elemental gases.
The sun is 865,000 miles in diameter and has a mass one-third of a million times ......greater ....(great) than the Earth's. Scientists believe that it's two billion years old and, instead of cooling, is still getting hotter. Perhaps, within the next two billion years, it will reach a temperature of sufficient intensity to destroy the Earth.
The sun's corona is almost as hot as interior. Solar prominences-tongues of hot gas-leap outward a half million miles from the sun's surface at speeds reaching 250,000 miles an hour. ........Fortunately... (fortune) , these prominences do not travel the full ninety three million miles to earth, nor are their terrific temperatures transmitted through space. Some of the energy from these ..disturbances ....... (urban) does not reach our atmosphere, however, and is believed to cause changes in weather.Our sun is actually an orange, dwarf star.
