Astronomy) Cygnus Loop Velocity. If the Cygnus Loop is 25 pc in diameter and is 10,000 years old, with what average velocity has it been expanding in units of km/s? (Note that 1 pc equals 3.1×1013 km and 1 year equals 3.2×107 seconds, to two significant figures.) Please round your answer to two significant digits.
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 do not exist forever they have a certain lifetime. The life span of the sun is about 10 billion years. The star undergoes various changes during its lifetime, this process is called stellar evolution. The structure of the sun-like star is shown below.
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 (red) side.
