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?

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.se]. There are already some questions over there about star color but yours seems not to have been asked yet. – Jan Doggen Mar 22 '16 at 09:18

4I'm voting to close this question as off-topic because it is not about earth or other planets. It belongs on Astronomy.SE – Jan Doggen Mar 22 '16 at 09:19

- 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.
