Rigel and Betelgeuse are counted in the brighteststars of the galaxy.
They form a pair in the Orionconstellation.
The Rigel star is situated near the Equator. This star is invisible in the region around and above of latitude 82°N and can be seen from any part of the world. It is a blue white giant star. This makes Rigel helpful in navigation.
Betelgeuse is a red giant star which is visible from naked eye. It has the same diameter as that of Jupiter.
More than half of Earth's rain forests have already been lost due to the human demand for wood and arable land. Rain forests that once grew over 14 percent of the land on Earth now cover only about 6 percent.
They have to wait for the right weather to dig a grave. If it looks asthough it is about to rain then they will know that all of the soil will fall inside the grave.
