What is this star in the sky that twinkles several colors?

Ok well ive been seeing this star in the sky everynight and I still do not know what it is.





It is the same size as the other average stars in the sky, except this one has a little red twinkle, little blue twinkle, and a little white twinkle mixed in. And this one REALLY twinkles more than the others. I heard that it may be a pulsar star but am not sure.





I used stellarium and located the star but it does not say anything special about it.





Help?|||A Stars colour (actual colour) does not change in the small time spans you are refering to. Its apparent colour changes due to scintellation in the atmosphere between you and the star. Its a refraction type effect (ie like a rotating prism).|||From your description, I'd say that you are looking at the star Sirius. It is the brightest star, bright enough to stimulate the colour receptors in our eyes, so that we see it twinkle in colours. It is just an ordinary star, not a pulsar, which is bright mainly because it's relatively close to the Sun, 8 light years away. The scintillation you're observing is strictly an effect in the Earth's atmosphere, nothing to do with the star itself.|||Well that is very vague, all of the stars twinkle especially on hot nights. The only reason it twinkles is because there is a lot of temperature differences in the air. So if you want to know what it is you need to give position in the sky and your location at what time you are looking at it.|||I've seen the same thing. Let me guess - the star is quite low in the sky, right? Near the horizon?


It's not limited to just one star. This kind of chromatic abberation in twinkling stars is common when viewing them through more atmosphere - especially turbulent atmosphere. It's just more noticeable with brighter stars.


I can't think of any pulsars visible with the naked eye.|||It isn't a pulsar. It is a star whose light gets distorted as it comes through the earth's atmosphere (an effect known as scintillation).
