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?

  • $\begingroup$ This question is not about earth sciences - it is about actual intrinsic star colors (your title says 'twinkling' but your text does not), and belongs on Astronomy. There are already some questions over there about star color but yours seems not to have been asked yet. $\endgroup$ – Jan Doggen Mar 22 '16 at 9:18

  • 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.
