Explanation The luminosity is defined as the rate of the energy emitted by the surface of the star. The brightness of a star is due to the luminosity of the star. The higher luminosity accounts for the more brightness of the star. The luminosity of a star depends on the temperature of the star and the surface area of the star from which the energy is emitted out. The higher the temperature and the surface area more will be the luminosity of the star...

Stellar evolution

We may see thousands of stars in the dark sky. Our universe consists of billions of stars. Stars may appear tiny to us but they are huge balls of gasses. Sun is a star of average size. Some stars are even a thousand times larger than the sun. The stars d…

Red Shift

It is an astronomical phenomenon. In this phenomenon, increase in wavelength with corresponding decrease in photon energy and frequency of radiation of light. It is the displacement of spectrum of any kind of astronomical object to the longer wavelengths…
