On earth, during a cloudless night, while sunlight does not outshine the stars, 2,000 to 3,000 stars can be seen by the naked eye. They crowd the night sky and it is impossible to count them without using any tool. The number of stars that people see every night change as the Earth revolves around [...]
Stars, the bright, twinkling tiny spots of light that can be seen in the sky during the night, in fact have sizes that a human brain would not be able to exactly picture. These balls of light are so far from the earth that their distance is also unbelievable.
The nearest star from the earth [...]
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 [...]
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 [...]
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 [...]
What is a Shooting Star.
A shooting star is another name for a meteoroid that burns up as it passes through the Earth’s atmosphere. In other way we can say that a shooting star is the common name for the visible path of a meteoroid as it enters the atmosphere. A shooting star is also broken [...]
The sun is a typical star which is about 150 million km away from the Earth. Solar ennergy provides virtually all the heat & light which are received by our planets & it therefore sustains every living entity. The character of our own environment is strongly influenced by solar radiation which has been a major [...]
