do stars glow in red colour?

Question

i am living in the south western part of india.for the past 2 days i saw a star like thing which glows in red colour.probably it was in the south east direction .it didnt move but it got dissapeard at the midnight.can any (good)space researcher can give me the answer for my question

i live in the southwestern part of india.i saw a star like thing blinking with blue and red colours.eventhough it was seen in the night it dissapeared in the mid night.if there are any(good)astonamaur can you tell me the reason

Answer 1

Nope! it may be a aircraft which was at a very far distance. But the way, there are some stars which may also appear red to our eyes due to certain factors. But my answer was no because such red appearing stars can only be seen through North and South Poles !

Answer 2

yes, there are probably more red stars than any other color...called red dwarf stars.

Since it stood out from the other stars in the sky, I would guess that it was unusually bright...and given the time of year, it is probably Betelguese in Orion or Aldeberan in Taurus. Could you describe the pattern of the other stars in the vicinity of your star?


Uhm, no, it could not be Vega...first of all, it sets very early this time of year. Secondly, Vega is blue or blue/white...definitely not red.

Sorry, Mars doesn't rise till just about sunrise right now, so that's out. Andromeda never looks red...gray if anything...and never starlike.

Viewing from the poles does not effect the color a star appears. And if you saw if for longer than a few minutes, then it was not an aircraft.

Answer 3

Well..dear fede...I am not a good space researcher though, but , as far as my knowledge holds good red star's such appearance might be because of refraction and scattering through the different layers of atmosphere. Also a star can be a red giant but I don't know whether we are able to see red giants. As you said it didnot move and disappeared at the midnight so may be it was not actually a red one. It might also be a planet like mars !!..

Answer 4

There are several stars which fit your description; to identify it we need to know the time and direction of your observation, and your location on Earth. If you are in the northern hemisphere and the star is low in the south in the evening, it is probably Antares. If it is early morning, just before dawn, and the star is low in the east, it could be Aldebaran or Betelgeuse. All three of these stars are bright red giant stars. There's also Arcturus, in the west just after sunset, which is brighter than the first three, but more orange than red.

Answer 5

There are red stars. Betelgeuse in Orion is one and it probably sets around midnight for southern India.. You can see a map of your sky by going to http://skychart.skytonight.com/observing/skychart/skychartobloc.asp and filling in your location and time.

The color of what you see in the sky can also be affected by atmospheric conditions. Objects very low in the sky often appear reddish because the atmosphere scatters blue light. Dust or smoke in the air can also add a reddish tint. "Twinkling" can make a star look as though it's flashing in different colors. This is due to turbulence in the air and like the red color is stronger for stars low in the sky.

Answer 6

You may have been looking at Mars or like someone mentioned previously, a distant aircraft. It may have been something much larger, like Andromeda:

Messier 31 is the famous Andromeda galaxy, our nearest large neighbor galaxy, forming the Local Group of galaxies together with its companions (including M32 and M110, two bright dwarf elliptical galaxies), our Milky Way and its companions, M33, and others.

Visible to the naked eye even under moderate conditions, this object was known as the "little cloud" to the Persian astronomer Abd-al-Rahman Al-Sufi, who described and depicted it in 964 AD in his Book of Fixed Stars: It must have been observed by and commonly known to Persian astronomers at Isfahan as early as 905 AD, or earlier. R.H. Allen (1899/1963) reports that it was also appeared on a Dutch starmap of 1500.

As for star colors, they stem from conditions surrounding a star at its birth. Stars are born with varying amounts of mass. Maybe you’ve heard that our sun is a medium-sized star—many stars are less massive than our sun, and some stars are much more massive. The most massive stars have the most powerful self-gravity. Their own gravity squeezes these stars inward—heating them up inside to extremely high temperatures.

How hot a star gets determines its rate of thermonuclear fusion—that’s the process by which stars shine. The most massive stars have the fastest rate of fusion, and these stars shine most brightly. Meanwhile, the least massive stars have relatively weak gravity. They’re cooler, so they shine more dimly. Star colors are related to star masses and star temperatures. Just as something white hot on Earth is hotter than something red hot, so white stars are hotter than red stars. And blue stars are the hottest of all.

Answer 7

There are red dwarf stars, but their reddish color spectrum is filtered out by our atmosphere and so they appear as indistinguishable from other stars.

The body that you saw was most likely the planet mars. With a good telescope, you can just make out the white smears on the poles of the planet that are its ice caps.

Answer 8

The answer is yes. Turning into a red giant star is part of the lifecycle of a star. ALL stars turn red at their late period in life. The sequence is Protostar, Main Sequence, Red Giant, White Dwarf/Neutron Star, Black Hole. A white dwarf doesn't change into a black hole. Only neutron stars with large amounts of mass change into black holes.

Answer 9

not all the stars glow in red colour
a star has life cycle as the humans too have
yes some stars may glow red in colour
that stars might be in the red giant phase
a phase in which a star becomes red in colur

Answer 10

It was most likely a plane or some other terrestrial object. But there are certain stars that can glow red and blue.
