Can you see galaxies through a telescope?
Galaxies are some of the most distant objects we can observe. While most planets, stars, and nebulae are usually pretty nearby to us, we can observe galaxies that are millions of light-years away. Even if a galaxy is bright, the most you might typically see is its core with a 4-inch telescope.
What is the difference between the light I See and stars?
The light you see is the light that has arrived at the earth, at your telescope, and at your eye. But the light you are seeing left some time ago. Normally this wouldn’t make much difference. Light is very fast. But stars are very far apart, so that light took years to get here. You are not seeing light before it left.
What does a star look like through a telescope?
What the star looks like through a telescope would depend on the type of telescope you are using. If you are using the most basic telescope for stargazing, the star will look just like a typical star. It will be a small dot, but it is bigger than when you are using your naked eye to look at it.
Is it possible to observe the planets with a home telescope?
It is definitely possible to observe the planets with your home telescope. Depending on which celestial body you chose to look at, even the more modest equipment can offer good viewing.
Can aliens see Dinosaurs through a powerful telescope?
Scientists claim that if an alien 65 million light years away sees earth through a powerful telescope, they can see “dinosaurs”. How can that be possible? This question raises the fascinating issue of look-back times.
