What are those stars in the night sky that blink different colors?

Question

It is not an airplane!!!!!! It is not low in the sky. It is high in the sky and blinking different colors. It moves with the stars. Is it a pulsar or something?

Answer 1

I read the posts and everyone has most of the reasons why they blink in different colors, but the blinking itself is from distance. The distance the light has to travel to reach here is so far that the waves are actually stretched out. This is the blinking we see. As for different colors I think everyone else allready nailed that one blue stars blue dwarfs, red giants yellow stars etc. But also remember the red shift that stars undergo if they are moving away from us at high speeds. (I read that is how they came up with the age of the universe)

Answer 2

that is not a satellite tv for pc. that's the two Sirius in Canis important or Rigel in Orion. differences in temperatures of distinctive air layers and winds are why stars twinkle. the two stars are white and superb, so the diffraction outcomes are seen too human eyes. you are able to not have in all probability seen this each and every night for 2 or 3 years, because of the fact the celebrities seems to go simply by Earth's rotation around the sunlight. you are able to not see Sirius or Rigel while the sunlight is up. What you in all probability meant replaced into which you had seen this famous guy or woman at approximately an identical time on an identical time of 300 and sixty 5 days for 2 or 3 years. Stars upward push 4 minutes in the previous than the day in the previous every day and constellations upward push later because of the fact the 300 and sixty 5 days progresses. As reported above, Fomalhaut does this too, and it is in a factor of the sky the place there particularly few superb stars. it is up suitable now.

Answer 3

There are two reasons for stars doing that. First of all, when stars are closer to the horizon they will look redder. But their light will also be subjected to more refractive irregularities in the atmosphere...like heat waves. This often has a prism-like effect on the light, causing it to look like it is changing colors.

The other reason is because stars are different colors. Not everybody can see this readily, but some stars are very much toward the red end of the spectrum and some are more blue. This is because of their temperatures.

And a question of my own. If every question about the natural world can be answered, "God stuff," then why bother learning anything? Why bother going to a forum that exchanges scientific information? Why bother saying that to someone who is looking for a real answer?

Answer 4

All bright stars twinkle in different colors. The light from the stars is made up of all the colors in the rainbow, that is why it is white. When a star is low over the horizon, it has to travell through more air to get to your eye so in the way the atmosphere acts like a prism decomposing it into all the wavelegths. Also, it is subject to more air currents because of the gradual cooling of the earth in nighttime.

Answer 5

I was just looking for something similar- specifically, what star is currently in the western sky at 1:30 am CST that blinks red?

Answer 6

Those are regular stars. The colors are caused by refraction through moving air. There is more warm moving air closer to the horizon so these stars appear to twinkle more than stars higher over head.

Answer 7

Some stars are "red giants", such as Betelgeuse in Orion (no one will show up if you say it 3 times). Others are blue-hot stars such as Sirius, and have a white-blue color. Mars appears as a red "star".

Answer 8

they sometimes might look like they are blinking because of the atmospheric gases are passing them and so create a blinking effect of different colours

Answer 9

Well, if they appear to be moving, they're airplanes.

Answer 10

They're called "airplanes."
