How many light years away is Sirius the stars?
Sirius, the brightest star in the night sky, is located about 8.6 light years away from Earth.
What is the blue area behind the stars called?
At dusk the sky looks blue behind the stars. In fact the sky is within 100 km while the stars are light-years away.
Why are the stars that you see in the sky now how they looked like thousands of years ago?
The light from stars takes a long time to reach us due to their immense distance from Earth. When we observe a star in the sky now, we are seeing the light that was emitted by that star thousands of years ago. This is because the speed of light is finite and the universe is vast.
How far is canopus from earth in light years?
Canopus, one of the brightest stars in the night sky, is approximately 310 light-years away from Earth.
Why do stars that don't exist still stay in the sky?
Stars that don't exist still stay in the sky because the light that we're seeing in the sky is about 10 years old because it takes so long for the light to get here due to the stars being billions of miles away
How many light years between Alkaid and Merak stars of the big dipper?

Why do people say looking at stars is like looking in the past?
Because the speed of light is finite (around 186,000 miles per second) and the stars are so distant, it takes a long time for the light to reach the telescope from the stars - at least 4.2 years. Many objects are millions of light years distant, meaning that what we see in the sky is from the distant past.
Where are the stars you see at night located?
Relative to you, in the sky. In actuality, they are in space, light years away.
How do stars form constallations in the sky?
The constellations are imaginary patterns that one can see in the stars at night. In reality the different stars a light-years away.
Which is further the stars or the sky?

How much light do you actually see looking at a star in the night sky?
As many as the stars.
Is it possible that the starlight you see in the night sky is from a star that no longer exists?
It is possible but highly unlikely. The stars you see in the sky are light years from Earth, meaning the light takes years to reach us and so we see the stars as they were years ago. For example, if a star is 50 light years away we see it as it was 50 years ago. The nearest star in the nigh sky is just over 4 light years away and most of the ones we see are within a few hundred light years. A few hundred years is insignificant in the life cycle of a star. Even the shortest-lived stars last for millions of years and most last for billions.
