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.

Can NZ see the Little Dipper?

No, the Little Dipper is not visible from New Zealand because it is circumpolar and only visible in the northern hemisphere. However, New Zealand does have its own distinctive star patterns visible in the night sky, such as the Southern Cross.

WHY DOES the big dippers location change?

The Big Dipper's location changes in the night sky because of the Earth's rotation. As the Earth spins on its axis, different constellations appear to rise and set, creating the appearance of movement in the sky. This phenomenon is known as diurnal motion.

Circumpolar constellations appear to rotate around?

The North Star, or Polaris. This star remains nearly stationary in the sky while all other stars seem to rotate around it due to the Earth's rotation on its axis.

Are there circumpolar constellations on the equator?

No, circumpolar constellations are those that never set below the horizon as viewed from a certain latitude. On the equator, all constellations are visible at some point during the year but none are permanently circumpolar.

Who named the scorpius and when?

The constellation of Scorpius the scorpion is very ancient and seen as a scorpion by many cultures around the world. The Greeks, Sumerians, Mayans, American Indians and various other ancient cultures identified the pattern of stars we know as Scorpius as a scorpion. The actual name Scorpius is the Greek name we now use. This name has been with us for at least 2300 years.

How come star constellations stay the same if stars die?

They are like any of the other stars, and they will run out of fuel eventually. Many of them may have already burned out, but light evidence of the events has not yet reached us.

___________________________

They all will, eventually. But the lifespans of stars are generally longer than the lifespans of entire species. The only major "constellation star" that might possibly "burn out" in our lifetimes is the red giant star Betelgeuse, at the shoulder of Orion. Betelgeuse is a relatively old star; about 10 million years old, which is very short for a star, but the bigger the star, the faster it burns out. Astronomers expect Betelgeuse to explode in a titanic supernova explosion "real soon now" on an astronomical time frame - which means any time between "now!" and about 100,000 years from now.

Fortunately, Betelgeuse is about 800 light-years away, so when explodes the Earth will be in no danger. But it ought to be a spectacular sight, shining as brightly as the full moon does!

How do astronomers label some stars within constellations?

Astronomers label stars within constellations using Greek letters, such as Alpha, Beta, Gamma, etc., in order of their brightness within the constellation. For example, the brightest star in Orion is labeled Alpha Orionis, or Betelgeuse.

What is the positions of the Big Dipper during the four seasons?

The Big Dipper is visible year-round in the Northern Hemisphere. During the spring, it is high in the sky in the evening. In the summer, it is low in the north around midnight. In the fall, it is visible in the early evening to the northwest. In the winter, it can be seen low in the north in the early evening.

How often does the Ursa major revolve pole star?

Find Ursa Major, the "big dipper". Follow the lines of the two "bowl" stars Merak and Dubhe out from the lip of the bowl. Go seven times the distance between the stars, and you will see one star which is not particularly bright, but is brighter than the other stars around it. This is Polaris, the "North Pole" star.

To check your work, follow the line from the dipper to Polaris an equal distance across the sky. You should be in the middle of a giant crooked "W" of stars; this is the "Chair of Cassiopeia".

What constellations are visible year round?

you can use google earth's google sky feature. Use google earth software to go to your current location. Next switch to google sky mode and you will see the night sky. the only downside is it doesn't compensate for time of year.

Why is the Big Dipper shaped like a bowl with a crooked handle or a big spoon?

The Big Dipper does not exist in the sky. What we see in the sky are simply assorted points of light, some brighter than others.

We human beings, however, can't stop trying to fit everything that we see into patterns. And so we see assorted dots of light, and our minds imagine patterns - and after one person has said "I see THIS shape in the patterns", many other people are persuaded to notice the same shapes. The Big Dipper exists only in our minds and our imaginations. In England, the same constellation is called "Charles' Wain" because someone thought it looked like a wagon.

The Big Dipper is what it is; it's lights in the sky. From other solar systems, it wouldn't look the same; the shapes would be different, and we would see other patterns.

Explain how stars can form a constellation when seen from earth but can still be very far from each other?

It depends on what you mean by "constellation." Most people think of the word constellation as meaning the patterns made by stars in the sky (the technical term is asterism). It is possible for a star to be part of two (or more!) asterisms, and different cultures have seen different patterns. Probably the most well-known example is the Big Dipper (or Plough, or Sickle). The stars that make up the Big Dipper are a subset of the stars making up Ursa Major (the Great Bear). Another example is Andromeda and Pegasus, which at one time were considered to "share" the star Alpha Andromedae/Delta Pegasi. Officially, however, the IAU defines constellations as specific regions of the sky, sort of like how nations or states are specific regions of the Earth. It's not possible for a star to lie in two such regions at once; all the stars in the Big Dipper are in Ursa Major, and Alpha Andromedae is now considered to lie in Andromeda only.

What happens if you get stuck in the middle of a worm hole?

If you were to get stuck inside a wormhole, it is uncertain what would happen as our current understanding of wormholes is largely theoretical. Some theories suggest you may be trapped in a spatial distortion, while others propose you could be stretched infinitely. Regardless, it is crucial to remember that wormholes are purely hypothetical constructs at this point and have not been observed in reality.

Which is the brightest star alkaid or mizar?

Alkaid is the brightest star in the constellation Ursa Major, while Mizar is a fainter star in the same constellation. Alkaid is a hot, blue star that is much more luminous than Mizar, which is actually a double star system.

What is the closest constellation to the Dorado constellation?

I don't know which is actually "closest", but all of these constellations border Dorado:

Caelum

Horologium

Reticulum

Hydrus

Mensa

Volans

Pictor

Do constellations change depending on the country you are viewing them from?

Yes, the constellations visible in the night sky can change depending on your location on Earth. This is because the Earth's rotation causes the stars to appear to move across the sky, making different constellations visible at different times and in different locations. The constellations that are visible also change depending on the time of year due to the Earth's orbit around the Sun.

What are the names of the nine stars in the constellation columba?

"The" nine stars is wrong.

Columba - or any constellation for that matter - contains billions upon billions of stars. That includes galaxies outside the Milky Way Galaxy. A constellation is really just an area of the sky.

There are of course a few bright stars which we can easily see.

I've put in a link which should answer the question, but it only names seven

stars.

heading "constellations". Finally click on "Columba".

Which constellation has the fewest stars?

The constellation of Crux, also known as the Southern Cross, is thought to have the fewest stars of all the modern constellations, with just five main stars.

What constellations are next to Taurus?

The constellations next to Taurus are Auriga, Gemini, Orion, Eridanus, and Cetus. These constellations are located around Taurus in the night sky.

What did Brahe discover near the Cassiopeia constellation?

Tycho Brahe discovered a bright new star, known as a supernova, near the Cassiopeia constellation in 1572. He observed that this star appeared suddenly and eventually faded away, which challenged the belief at the time that stars were fixed and unchanging.

In which constellation does Mars appear in the sky?

A star will appear in any of the 88 constellations.

A star will appear in any of the 88 constellations.

A star will appear in any of the 88 constellations.

A star will appear in any of the 88 constellations.

The big dipper appears at 9pm on which day of the month?

Here's a rough table:

October 1: . . 12:00 Noon
November 1: 10:00 AM
December 1: . 8:00 AM

January 1: . 6:00 AM
February 1:. 4:00 AM
March 1: . . . 2:00 AM

April 1: . . 12:00 Midnight
May 1: . . 10:00 PM
June 1:. . . 8:00 PM

July 1: . . . . . . 6:00 PM
August 1: . . . 4:00 PM
September 1: 2:00 PM

General approximate rule for stars:
Wherever you see a star at some time tonight, as the dates pass, it will be in the same place about 4 minutes earlier each night, 1 hour earlier after 2 weeks, 2 hours earlier after a month.

How did Orion get in the sky?

The stars have always been there in the sky. But in ancient times before artificial lights, the night skies were DARK, and there wasn't much to do except make up stories about the shapes that the primitive hunters and shepherds say in the sky. The story of the great hunter Orion was made up about a pattern of stars that people saw that suggested certain shapes, like a club raised high, a shield, Orion's belt and dagger, and a dog (Canis Major) at Orion's heels.
