What else can I help you with?
How far would you have to move before the constellations would appear to change shape?
The constellations would not appear to change shape as you move because they are so far away that the relative positions of the stars remain constant from our viewpoint on Earth. This is why we can use constellations for navigation and timekeeping.
What does it mean Draco which is a constellation in the far northern sky?
Draco is a constellation in the far northern sky. Its name is Latin for dragon. Draco is circumpolar (that is, never setting) for many observers in the northern hemisphere. It was one of the 48 constellations listed by the 2nd century astronomer Ptolemy, and remains one of the 88 modern constellations today.Source: Wikipedia.
What do constellations appear to do?
Constellations appear to form images in the night sky, but each of the stars are extremely far away fron each other. They just line up from our own viewing points.
What is the two constellation?
There are far more than two constellations.The IAU (international Astronomical Union) recognises 88
How is a parallax helpful to astronomers?
Parallax is the apparent change in postion of an object when looked at from two different places. Astronomers use parallax to find how far away nearby stars are.
Can same star constellations be seen from Europe and Australia?
Some of them, yes. Constellations along the Zodiac can be seen from either hemisphere, but constellations well away from the celesial equator cannot be seen very far in the other hemisphere. For example, Ursa Major is not visible in Australia, and the Southern Cross is not visible in Europe or North America. Most of the "official" constellations were named by northern hemisphere astronomers, or European navigators sailing in southern waters. Look at how many southern hemisphere constellations have a nautical theme; the Telescope, the Octant, the Quadrant. Even Cetus, the Whale, was named by sailors, not people who LIVED there.
Do all constellations have nicknames?
No. There are some that don't exist as far as we know!

What are facts about constellation?
1. Every visible star in the sky is part of a constellation. 2. A pattern in the sky that is widely recognized but not an official constellation is called an asterism. Ex. The Big Dipper or the Plough. 3. Many of the stars that make up constellations are extremely far apart but only appear to be close together.There are 88 named constellations.The Plough is part of the Ursa Major.The Constellation Sexans the Sextant is a Modern Creation.There are twelve constellations in the Zodiac.The Pole Star is in Ursa Minor.

Why do some constellations apper only during certain seasons?

What did Edwin Hubble do to get recognized in his field?
Hubble was a legend among astronomers, for many reason, but his most noteworthy achievement was probably the discovery and subsequent proof that what were called at that time "nebulae", were actually separate galaxies like our own, and hence very far away from us. That one discovery kind of took astronomy from "high school" to "college"

Why do astronomers say that looking at constellations is looking into the past?
Because of the speed of light. A light year is a term of measurement of distance, not time - i.e. the distance that light can travel in one year. Light travels at 299,792,458 metres per second - almost 3 million kilometres a second - therefore in one year it would travel a collosal distance - near 94 million million kilometres. When astronomers say a planet is 400,000 light years away, what we see of this planet happened 400,000 years ago since the light is only reaching us now. It would be another 400,000 years before we see that planet as it is today.
Why does the number of circumpolar constellations depend on latitude?
Circumpolar Constellations are those that appear to circle the North Star, Polaris. Polaris' place in the sky changes based on the viewers latitude. The closer you get to the North Pole, the higher in the sky Polaris appears, and therefore the more constellations appear to spin around Polaris.
