Constellations
Constellations have fascinated astronomers for centuries. They are arbitrary formations of stars perceived as a figure or design, especially one of 88 recognized groups named after characters from classical mythology and various common animals and objects. Questions about the various constellations of stars are what this category is all about.

What is the right ascension and declination of the Cancer constellation?
The Right ascension is 07h 55m 19.7973s-09h 22m 35.0364s and the Declination is 33.1415138°-6.4700689°.
Why steam is sometimes visible as in winter?
Its not, steam and water vapor, both gaseous forms of water, are invisible. Water on earth's surface, below it's surface, or in its atmosphere is only visible in the form of liquid or ice. Its possible that under pressure conditions elsewhere in the universe that gaseous water could be visible.
How do you find the constellation Aquarius the Water Carrier?
Aquarius, the Water Bearer, is best viewed late in the Autumn months (Northern Hemisphere). It is the constellation to the "left" of Capricornus, the Sea Goat, which is easy to spot since Jupiter is currently 'wandering' through it (as of 9/2/09).
If you live in an area with a very dark sky (away from the glare of city lights), you can make out a few dozen stars that seem to resemble cascading water... just before you move into Pisces, the Fishes.
What is the temperature of the little dipper?
It doesn't have a temperature. It's a group of individual stars.
How do you see different constellations in the sky at different times of the year?
The relative position (direction, actually) of a constellation and the Sun changes, due to Earth's orbit around the Sun. Thus, at one moment the Sun might be in a certain constellation; half a year later, the Sun will be in a constellation opposite in the sky.
How many stars are in the constellation Polaris?
Polaris is not a constellation but it is the brightest star in the constellation Ursa Minor, the Little Bear. Polaris is not a single star just like half of all known stars are not single stars like our sun but are normally in a system of two or more stars. Polaris is part of a system that is four stars. It's closest companion known as Polaris Ab is easy to see in a small telescope.

What is a pink star in the sky there is one in front of my house?
If you are in the Northern Hemisphere, and the front of your house faces south, it is probably Antares, the brightest star in the constellation Scorpio.
What is a smaller group of stars within a constellation.?
It can be called a star cluster, an open cluster or an asterism.
What constellations are circumpolar (visible all year, at any time of the night) depends on your latitude. If you are (for example) at a latitude of 50° north, then any start that is 50° or less from the sky's north pole will never go below the horizon. For a more detailed explanation, read the Wikipedia article on "Circumpolar star".
Are constellations hard to find?
No, you look up at night and there they are.
If you're asking if they're hard to recognize.... some of them are more widely known than others. Most people in the northern hemisphere have little trouble recognising Ursa Minor or Orion, but not too many can identify Cancer (which is, visually, mainly a rather dark patch between the more recognizable Leo and Gemini) or Ophiuchus (to which the normal persons's response is "There's a constellation called Ophiuchus?")
What are the names of the stars in the Centaurus constellation?
The two main stars are Alpha Cen (Rigel Kent) and Beta Cen (Hadar or Agena)

Can the big dipper be seen from Trinidad and Tobago?
Yes, but it is very low on the horizon, and is only visible during certain seasons.
What Constellations are visible all year?
The constellations near the plane of the ecliptic (the zodiacal constellations) are only visible at certain times of the year.
The constellations towards the poles (N and S) are visible at all times of the year from their respective hemispheres. In the South, the Southern Cross would be one example and in the North the Great Bear (or plough) would be another.
How long the sun remains at one constellation?
It depends on the constellation, as they are different widths. The widest is Virgo, at 42º. Because the year is 365 days and a circle is 360º, each degree approximates one day that the Sun rises in that constellation, so the Sun rises in Virgo for just over 42 days.
The narrowest constellation is Scorpio. At only 5º of the zodiac, the Sun rises in Scorpio a bit over 5 days, statistically.
That's the name of a constellation. Also called Ursa Minor.
