supernova
what are the causes of
A supernova happens where there is a change in the core, or center, of a star. A change can occur in two
different ways, with both resulting in a supernova. The first type of supernova happens in binary star
systems. Binary stars are two stars that orbit the same point. One of the stars, a carbon-oxygen white
dwarf, steals matter from its companion star. Eventually, the white dwarf accumulates too much matter.
Having too much matter causes the star to explode, resulting in a supernova. The second type of
supernova occurs at the end of a single star’s lifetime. As the star runs out of nuclear fuel, some of its
mass flows into its core. Eventually, the core is so heavy that it cannot withstand its own gravitational
force. The core collapses, which results in the giant explosion of a supernova. The sun is a single star, but
it does not have enough mass to become a supernova.

meteors, meteorodes, metiorits
meteors
a small body of matter from outer space that enters the earth's atmosphere, becoming incandescent as a result of
friction and appearing as a streak of light.
meteoroids
a small body moving in the solar system that would become a meteor if it entered the earth's
atmosphere.
metiorites
a meteor that survives its passage through the earth's atmosphere such that part of it strikes the ground. More
than 90 percent of meteorites are of rock, while the remainder consist wholly or partly of iron and nickel.
galacies
types of
There are three main types of galaxies: Elliptical, Spiral, and Irregular.
