In the nothern hemisphere, the north star (and circumpolar stars) are visible any night of the year. The reason the southern constellations vary with the seasons is due to earth's orbit of the sun. In winter the earth is on the opposite side of the sun as it is in the summer, thus the winter night sky is very different from the summer night sky. The winter day sky resembles more closely the summer night sky, if the sun weren't there to block instreaming starlight.
Because the Earth is orbiting the sun. As we do so, we see different things in the sky. It is like if you put a lamp in the middle of a room and then walked around it, while also rotating. Depending where you are in the room, when you have your back directly facing the lamp, you will see different things. If it is a very bright lamp, when you look at it, it is hard to see what is behind it. But if you go half way around from that point, the things you could not see before are clearly visible.
Because the Earth is spinning in a different direction at that time of year.Sort of.
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!
the earth orbits around the sun, in winter, the earth on one side of the sun, while in summer, the earth is on the other side. therefore, the night sky faces a different direction in winter than summer, which is why the constellations are different
The star patterns change by season due to the Earth's tilt on its axis. As the Earth rotates about its axis, the portion leaning towards the sun changes. This brings different portions of the night sky into view at a particular location throughout the year.
because The Milky Way revolves to a different position with each season.
The night sky faces in opposite directions in sumer and winter
Now, (beginning of November), the same constellations are rising 8 hours earlier than they did on July 1.
Because they are
because the earth orbits the sun so we see different stars in the summer and the winter
In the northern hemisphere the constellations on the meridian on June 21 have a right ascension of 18 hours, and constellations from 15 to 18 hours can be seen in summer evenings. They are not as bright as the winter constellations. The main ones are Boötes (main star Arcturus), Corona Borealis, Serpens Caput, Libra, Hercules and Ophiuchus. In the southern sky, Scorpio (main star Antares). In the summer the circumpolar constellations like Cassiopeia, Ursa Major, Perseus and Draco can be seen although not in their usual winter positions.
It is summer, marking the start of summer for some people and the middle of summer for others, as there are different perspectives on it.
Depends where you live.
More wax is added in the summer to make it take longer to melt.
yes,there are two different types of smog i.e summer smog and winter smog
The winter night sky is the opposite direction from the summer night sky. The constellations you see in winter are on the other side of the sun in summer, so you would only see them in summer during a total solar eclipse.
As the earth orbits the sun over the course of a full year, the side of earth in darkness (night) will face out toward a different direction. The winter constellations are those that are in line extending from the sun through earth out into the galaxy during winter, and the summer constellations are those on the opposite side of the sun. Therefore, during different seasons you are actually seeing different parts of the universe due to earth orbiting the sun.
The Earth is tilted. As it goes around the sun we see different areas of the sky during the year.
As Earth orbits the sun - it takes one year to get around it - we see different parts of space and different patterns of stars, as Earth turns away from the sun every night. The constellations we see on a night in summer, are behind the Sun during the winter.
Because in the summer the constellation would be in the daytime sky.
Actual constellations such as Leo and asterisms such as the Big Dipper and Summer Triangle.
It is both, as Cassiopeia is one of the constellations that can be seen all year round.
Constellations are different in winter because the earth spins around, so we see different stars every season.
First of all - constellations are simply patterns of stars. As Earth travels around the sun once every year (it's orbit), we see all the different stars, in all the different directions in space, as we turn away from the sun every night. So - the constellations we see at NIGHT in the SUMMER are the same ones that are in the DAYTIME sky during the WINTER - we just can't see them because our atmosphere scatters the sun's light during the day.
This is caused by the earth's rotation around the sun. There are five constellations in the sky all year around, but the earth's rotational path will only allow us to observe the ones that are closest during that season's orbit.
No - as Earth rotates the stars and constellations seem to move. Also, as Earth orbits the sun over the course of a year, the stars we see at night in the winter are different than the stars we see at night in the summer. Same with Spring and Fall.
Earth rotates on its axis.
