Solar System is the family of planets on which we exist. Our wonderful blue planet is the third in line from the Sun. We look on Sun every day.
Astrophysics is the branch of astronomy that employs the principles of physics and chemistry to ascertain the nature of astronomical objects.
The science goals of the James Webb Space Telescope are to look for stars and galaxies that formed just after the Big Bang took place.
The Big Bang Theory is a cosmological model of the observable universe from the earliest known periods through its subsequent large-scale evolution.
Spectroscopic parallax is an astronomical method for measuring the distances to stars. It can be applied to any main sequence stars for which a spectrum can be recorded.
Radio astronomy is the sub-field of astronomy that studies celestial objects at radio frequencies. It was first used in 1932.
Visible light astronomy encompasses a wide variety of observations via telescopes that are sensitive to the range of visible light.
Historically, two basic scenarios of the origin of the Solar System have been discussed. In one, the Solar System formed as a byproduct of the Sun’s formation.
Length contraction and time dilation are some of the relativistic effects. They do not fit in with the traditional Newtonian Mechanics.
When a main-sequence star has consumed the hydrogen the loss of energy generation causes gravitational collapse and star evolves off the main sequence.
