This is because the stars are so far away, that it takes the light from them thousands of years to get to Earth.
Constellations like Leo, which represents a lion, do not have a lifespan as they are simply groupings of stars in the sky. These stars have varying lifespans ranging from millions to billions of years. The pattern they form in the sky can be seen for thousands of years as long as the stars themselves are visible.
Constellations do not have an age in the traditional sense as they are patterns of stars seen from Earth. Orion has been observed for thousands of years and its association with mythology dates back to ancient civilizations like the Greeks and Egyptians.
Stars range in many different shapes and sizes some have super energy and others have less energy. Usually the more mass the star has the more light it will seem to emit more light, the distance can matter, one thing to remember when looking at the stars is that it can and does take thousands of years for the light from a star to reach the Earth. Some stars are brighter than others because they have more energy than others.
Pyxis, a constellation in the southern sky, is located thousands of light-years away from the Sun. It is not a physical object in space like a planet or star, but a group of stars as observed from Earth.
Oh, there's a wonderful little secret behind those twinkling stars in the night sky! You see, some of the light we see from the stars is actually thousands or even millions of years old, traveling through the vast reaches of space just to say hello to us at this very moment. It's like the stars are artists, creating masterpieces that span both space and time, just for our viewing pleasure. Simply magical.
some of the stars we see in the universe took millions of years to get here - we are seeing what it looked like a million years ago.
Somebody looked at the "clouds of stars" and thought it looked like milk spilt out in the sky.
Star gazing can be compared to time travel because when we look at stars in the night sky, we are looking back in time due to the vast distances light has to travel to reach us. The light we see from stars can be thousands or millions of years old, so in a sense, we are seeing how those stars looked in the past. It's a way to connect with the history of the universe and experience a sense of time beyond our own.
it looked like FOOD

he looked like a cheetah and his spots represented the stars
100 years ago, the many species of cacti looked just as they look today. The process of evolutionary change takes much longer than one or two centuries, but several (or many) thousands of years.
The galaxy was named after milk because when early astronomers looked at the sky they noticed a band of stars that somewhat looked like milk!
In ancient times it was thought that the constellation looked like an archer on horseback. Its also made out of stars, and stars are related to astrology.
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.
no more like thousands of years ago
Because we are observing the stars as they *where* not as they are now.If we look in the night sky, we see stars, some are close, some are further away.If we view, say Betelgeuse, we are seeing it as it was 640 years ago, because that is how far away from us it is in light years. For all we know it may have exploded as a supernova 639 years ago, but we won't know for another year.So the stars you are viewing in the night sky, is what a star looked like, depending on the distance from us.
