According to the astronomers first everything was an incredibly solid, heavy ball of a matter. This heavy ball exploded billion of years ago and as a result the Universe was formed. The moment of the explosion of this ball is known as “Big-Bang”. After this explosion the early universe was very small and too hot but later it got cooled and it exploded and spread out into the small pieces. Small pieces formed the …
A binary star is a stellar system consisting of two stars orbiting around their center of mass. For each star, the other is its companion star. Recent research suggests that a large percentage of stars are part of systems with at least two stars. Binary star systems are very important in astrophysics, because observing their mutual orbits allows their mass to be determined. The masses of many single stars can then be determined …
What is a Neutron Star.
A neutron star is a stellar remnant–a super-compressed object left over when stars with a mass between 1.4 and about 3 times the mass of our Sun exhaust their nuclear fuel and collapse inwards. The result is a condensed sphere of matter about 20 km across, with a gravitational field approximately 2 x 10^11 times stronger than that of Earth’s.
How Neutron Stars formed.
Neutron stars are formed when large stars …
Formation of Earth.
Earth is the third planet from the Sun and the fifth largest. The Planet Earth was formed 4.6 billion years ago from the same nebula cloud of gas and dust that the Sun and the eight other planets were formed.
Definition of Earth
Earth is the only planet whose English name does not derive from Greek/Roman mythology. The name derives from Old English and Germanic. There are, of course, hundreds of other names …
A Star can be defined as a massive and luminous ball made of Plasma. Basically, a star is formed out of cloud of cool, dense molecular gas. To become a potential star, the clouds need to collapse and increase in density.
Formation of stars can be of two ways: it can either collide with another dense molecular cloud or it can be near enough to encounter the pressure caused by a giant supernova. Several stars can be born at once …
