What did the name 'shooting star' come from?
Whoever looked into the sky first. "Shooting Stars" are just pieces of rock that enter our atmosphere and burn up producing light and this has been happening for millions, if not billion/s of years.
What type of star burns the longest?
The least massive stars, i.e., the red dwarves. More massive stars get more pressure and temperature, and therefore burn their fuel up faster. For comparison, while a red dwarf might shine for trillions of years, the most massive stars run out of fuel after just a few millions of years.
What was different about planets and stars in ancient times?
Almost nothing was different, except our understanding of things. The stars have been shining for millions or billions of years; all the planets have been pretty much just where they are for about 4 billion years or more. "Ancient" times in our human history is anything more than 2000 years ago.
How do star trails form?
Stars usually don't have "trails". If you see a "shooting star", that is not really a star, but a piece of dust that happens to fall into the atmosphere. It is also possible that you confuse this with pictures you saw of comets.
How did iguazu falls form?
Volcanic activity millions of years ago
What is the lifespan of most stars?
Millions Of Years
Do stars with less mass live millions of years?
No. Low mass stars live hundreds of billions to trillions of years. The highest mass stars may live only a few million years.
Does it sometimes take millions of years for starlight to reach earth?
Not for the stars you can see without a telescope. All of the stars you see at night are within a few hundred light years of Earth, so it does not take the light more than a few hundred years to reach us. There are stars in other galaxies that are millions or even billions of light years away. That light does take millions to billions of years to reach us, though the stars are too far away for us to thee them individually.
Are the stars that you see at night really present when you see them?
Yes. There is a common myth that the stars you see at night have burnt out in the millions of years it takes for their light to reach us.This is not true for two reasons.The stars you see at night are in usually no more than a few hundred light years away, so you see them as they were, at most, a few hundred years ago.Most stars last for billions of years, so a period of a few million years, let alone a few hundred, is not significant.
WHEN HAVE astronauts to exploreD a star?
its impossible to explore stars they're millions of miles away years in fact
Do changes in stars take place over billions of year?
Yes, Millions/Billion(S) of years.
How long will wolf rayet stars burn?
Wolf-Rayet stars are massive stars that are very hot.Because of this they will be VERY short lived and will only have a life time of millions of years as apposed to "normal" stars like our own Sun which will survive for billions of years.
How can you see stars if they are millions of light years away?
Because 1) they are very bright, most of them are bigger than our sun 2) light travels very quicky when you look at them, you are looking at the star about hundreds of millions of years ago, as that is how long it takes for the light to get to here.
What does it mean when people look up at the stars and say seeing them how they were millions of years ago?
Generally speaking, this is a gross exaggeration. You see the stars as they were, at most, a few centuries ago. The reason is the light travels at a limited speed. In other words, it takes time to reach you. Distance between stars is measure in light years, which is the distance that light travels in a year. For example, if you look at a star that is 100 light years away, the light you see now left it 100 years ago. The stars you see at night are within the small part of our galaxy that is closest to us. Those stars are at most a few hundred light years away. A handful are less than 10 light years away. The only thing you can with the naked eye see as it was millions of years ago is the Andromeda galaxy, a massive collection of stars 2.5 million light years away. With a telescope you can see farther galaxies.

Did dinosaurs really exsit?
Yes, Dinosaurs did exsit millions of years ago.
Do stars go through a long life cycle?
Low mass stars can last for hundreds of billions of years. Medium mass stars, like our sun will remain on the main sequence for roughly ten billion years. High mass stars, will last for millions of years. By any human measure, a million years is a long time.
