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.
What else can I help you with?
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 old is the light emitted from stars?
Oh, isn't that just a fascinating question? You see, when we look up at the stars in the night sky, we're actually seeing light that has traveled for years and even millions of years. So, the age of the light from each star depends on how far away it is from us - it's like having a little piece of the universe's beautiful history shining down on us every night. Just imagine all the stories that light could tell, all those moments painted with colors only the stars know how to mix. It truly is a mesmerizing thought.
Some stars don't exist but you can still see them at night. How?
because light travels at a finite speed of 186,000 miles per second, it can take light a long time to reach earth from such vast distances away (say, 12 million light years away). here on earth such effects are not noticeable due to the fact that everything is so relatively close together, light appears to travel instantaneously but in reality it doesn't. coming from stars so far away, it can take a while to get here. the light from the collapse of distant stars has not yet reached us, so we are seeing a "delayed" image, old light if you want to look at it that way. That said, it is reasonable to assume that all the stars you can see at night are still there. Most of the stars visible to the unaided eye are within a few hundred light years of Earth, so we see them as they were no more than a few hundred years ago, a fairly inconsequential period of time for a star.
How old is the light that we see from stars?
Well, isn't that just a fascinating question, friend? When we gaze up at the night sky and see those twinkling stars, we're actually seeing light that could be from millions or even billions of years ago. It's like looking back in time and witnessing the secrets of the universe unfolding right in front of us.
Do New stars form from the material of old stars.?
From the material of old stars.

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
Is it ok that my 13 year old sleeps with a night light?
There is nothing wrong with a 13 year old that still wants a night light at night. This is a personal preference and she should not be ridiculed or punished for wanting the night light.

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.
Why is light you see from stars several years old?
it takes light long to travel so you see it late
Why is the Irish flag not meant to fly after dark?
American National Flags are taken down at night as a sign of respect. There is an old saying in the military that "Stars and Stripes lead the way" however, just like soldiers, they need light to do so. That is why if a flag is left up at night that it is custom to light it with a spot light. It all goes back to the line in our national anthem about our flag.
If you are 11 years old now how old will you be when light that is leaving today reaches earth?
One light-year is about 9 trillion kilometers.Arcturus is a star that is 37 light-years from Earth.
How is star gazing like time travel?
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.

When you look at the night sky are you seeing the universe exactly as it is?
No, as it was. Light takes time to travel...hence, we have lght years, or the distance light travels over a year. It is assumed that the universe is 14 billion years old. When you look up at night you see star light that may be moments old and some thousands of years old, others millions of years old. Your seeing the fourth dimension, time... spread out, over time, all at one time.
