Facts about Lunar Eclipse for Kids

A lunar eclipse occurs when the Moon passes directly behind the Earth into its umbra (shadow).This can occur only when the sun, Earth and moon are aligned (in “syzygy”) exactly, or very closely so, with the Earth in the middle. A total lunar eclipse has the direct sunlight completely blocked by the earth’s shadow. Unlike a solar eclipse, which can be viewed only from a certain […]

Facts about The Little Dipper (Ursa Minor) for Kids

Ursa Minor, also known as the Little Bear, is a constellation in the northern sky. Like the Great Bear, the tail of the Little Bear may also be seen as the handle of a ladle, hence the name Little Dipper. Ursa Minor is notable as the location of the north celestial pole, although this will […]

Facts about Black Holes for Kids

John Archibald Wheeler coined the term to describe a collapsed star whose gravitational field is so intense that not even light can escape. The theory of general relativity predicts that a sufficiently compact mass will deform spacetime to form a black hole. This temperature is inversely proportional to the mass of the black hole, making it difficult to observe […]

Facts about The Full Moon For Kids

A full moon is the lunar phase that occurs when the Moon is completely illuminated as seen from the Earth. This occurs when the moon is in opposition to the Sun. Lunar eclipses can occur only at full moon, where the Moon’s orbit allows it to pass through the Earth’s shadow. Lunar eclipses do not occur every month because the Moon usually passes […]

Facts about Stars for Kids

Stars form when cool, relatively dense clouds (molecular clouds) of interstellar gas and dust shrink upon themselves as a result of gravitational collapse. In a spiral galaxy, such as the Milky Way, star formation is usually triggered when gas clouds are compressed by shock waves from nearby supernovae. The Birthplace of Stars Stars are born […]
