An eclipse occurs when one heavenly body such as a moon or planet moves into the shadow of another heavenly body. Let’s learn about the two types of eclipses on Earth. What Is a Lunar Eclipse? The Moon moves in an orbit around Earth. At the same time, Earth orbits the Sun. Sometimes Earth moves between the Sun and the Moon. When this happens, Earth blocks the sunlight that normally is reflected by the Moon. (This sunlight is what causes the Moon to shine.) Instead of light hitting the Moon's surface, Earth's shadow falls on the Moon. This is an eclipse of the Moon, or a lunar eclipse. A lunar eclipse can occur only when the Moon is full. A lunar eclipse can be seen from Earth at night. There are two types of lunar eclipses: 1.Total lunar eclipse. 2.Partial lunar eclipse. A total lunar eclipse occurs when the Moon and the Sun are on exact opposite sides of Earth. Although the Moon is in Earth's shadow, some sunlight reaches the Moon. The sunlight passes through Earth...

His proposition that all species of life have descended from a common ancestor is now generally accepted and considered a fundamental concept in science.[ This brilliant 19th-century naturalist’s intense curiosity about the diversity of species led him to a new understanding of the world around us—and our place in it. Evidence collected during the five-year voyage of the HMS Beagle led to Darwin’s revolutionary theory that species adapt to different environments and change over time: all life, including humans, has evolved from a common ancestor through the process of natural selection. The new tools of genetics and molecular biology continue to build on Darwin’s radical ideas and refine our understanding of the mechanisms of evolution, which is essential to the study of life sciences. Happiest at home with his notebooks and his microscope, he shunned the public eye. Controversy made him ill. This brilliant observer of nature kept his most original and revolutionary idea under wraps...
