What causes the constellation to disappear from the winter sky?

Answer 1

No, or at least not in most cases. At the poles you see the same constellations in winter or summer, and except for very close to the equator you can see some of the same constellations (the ones near the celestial poles) in both summer and winter.

Answer 2

It's a bit difficult to describe with only words and no sketches, but we'll try:

Picture this: The sun is over there, and you're over here, on the backside of the earth,

looking away from the sun at some stars, and you take a picture of those stars.

Six months later, you find the picture somewhere in a drawer, and you decide to go out

and look at the same stars again. So you go outside and look around the sky to find them.

But now, it's six months later, and the earth has traveled half-way around the sun. Where

do you have to look now in order to see those same stars ? Right through the sun!

Six months ago, they were straight ahead at midnight. Today, they're straight ahead at noon!

Answer 3

They don't disappear. The earth turns you around, so that you're looking the other way,
and the constellation you want to see is blocked by the earth being between you and it.

You can prove this easily. Find a constellation in the sky. Watch it move across the sky, and some time after
it drops below the western horizon and you can no longer see it, phone up a friend someplace in the
world that's West of you and where it's still night. Tell him to get out of bed, go outside, and look to find
your constellation. After you call him again and convince him that you mean business, he'll confirm that although
you can't see the constellation at the present moment, he indeed can.

Answer 4

No. Because of Earth's movement around the Sun, the relative direction of the Sun and stars changes. Therefore, the stars arise 4 minutes earlier every day. For example, if today a certain star rises at 6:00 p.m., 3 months later at the same time it will already be at the meridian (at its highest position in the sky).

Answer 5

The constellations don't disappear in winter. Not being able to see a particular one, is due to the earths position at a given time of year. Not seeing them at all could be due to atmospheric pollution, or more likely cloud cover.

Answer 6

Stand in the middle of a room and hold a ball in your hand, extended out in front of you. Turn around. The side of the ball facing away from you is like the night side of Earth. As you turn, different walls will be "visible" from the "night side" of the ball at different times. The side of the ball facing you is like the day side of the Earth. Constellations are not visible from the day side because the sun lights up the atmosphere, drowning all other stars out. So in winter, constellations don't disappear, they just move to the day side, where we can't see them.

Answer 7

No, you do not (in most places on Earth).

As the Earth orbits the Sun, it is "in" different constellations during the course of a year.

That affects the constellations that you can see at night.

However, depending on your latitude, some constellations can be seen all year.

That's because they are away from the path of the Sun in the sky and remain

above the horizon all the time.

Answer 8

-- The earth travels in a nearly-circular path around the sun. One full trip in one year.

-- The earth also spins. One full spin in one day. The sun shines on you during about 1/2 of

each spin, and doesn't shine on you during the other 1/2.

-- You look at the constellations when the sun isn'tshining on you. That happens

when the earth has you facing away from the sun.

-- In six months from now, we'll be around on the other side of our path around the sun.

The direction away from the sun today will be the direction toward the sun in six months.

-- In six months from now, when you look at the stars at night, you'll be looking in the

opposite direction from the stars you look at tonight. Naturally, you'll see different stars.

Answer 9

You can only see constellations at night. However, not all are visible at one time or one location. During the year the viewable constellations change as the earth orbits the sun. Also, there are ones that can only be viewed in the northern or Southern Hemisphere not both.

Answer 10

Clarity of the night sky is imperative! The higher the altitude, the less "light clutter" to prevent the lights of distance stars from arrival to your eye. A most unusual illusion is to be at sea when viewing the heavens. It becomes difficult to differentiate between the sea and the sky.
