What is the science behind the vigorous glow of stars ? Since 2 days I was observing one of the stars in blue and red colour I just want to know what is the speciality of that star?
- Stars do have different colors depending of their temperature,
- different intensities depending of their size, temperature and distance,
- twinkle is due to turbulence in the atmosphere (you don't have it in space).
- the glow you might see is a effect in your telescope, camera or eye. It has several components due to the opening size, imperfect lense, and captors.
