When astronomers study distant galaxies they notice changes to the waves they observe describe the change to the waves they observe?
Because the universe as a whole is expanding, distant galaxies are moving away from us. As a result, electromagnetic waves emitted by those galaxies experience what is known as a red shift. Their wavelengths get longer.
How does the appearances of a constellation seem to change at night?
The biggest notable change is that they appear to move across the sky. This is of course due to Earth's rotation, and not the constellation moving. Standing looking at a constellation, you will not notice it move. You would need something to relate it to, like something on the horizon. If you look very carefully, you will see movement. Over the course of a night, it will appear to move in an arc shape, rising and then setting. If you regularly viewed a constellation across a few days or weeks, you would also notice that the time they rise is different and the time they are visible at a certain point in the sky is different. You will not notice any change in the stars in relation to each other within a constellation. Even during a lifetime, never mind one night, a particular constellation will look the same to you, as the changes would be so slight. If the moon is visible near a constellation, you would notice some movement over the course of a night in relation to stars in the constellation, and certainly over the course of a few nights. If there is a planet near them, you will notice some movement, but not near as much as the moon. The nearer planets, like Venus and Mars are more noticeable in their changes compared to other planets.
How do you notice a fake diamond?
Notice is a confusing word to use in this context -- perhaps you mean identify.A gemologist can help you determine whether your diamond is lab-created or a natural gem.
Who is the astronomer that notice a strange pattern in the orbit of Uranus?
Neptune
Why dont stars move?
They do. Everything moves, all the time. Every star has its own "proper motion", and the galaxy as a whole spins once every 220 million years. We don't SEE the stars move, because they are so incredibly far away, and we don't live long enough to notice. But there are a few stars that would actually appear to move slightly during a human lifetime; Barnard's Star is perhaps the best example.
Who was the first explorer to notice different types of galaxies?
explorer? you probably mean astronomer.
How do you notice movement around?
by your ear
What you get when stars are moving away?
When stars or galaxies are moving away from the observer, you will notice a redder shift in the color of the body.
Do one direction notice their Arab fan?
yea after
When you moved the slides in different directions what change in the image of the specimen under focus did you notice?
You should notice that the image in the microscope moves in the opposite direction to the movement of the slide. For example, if the specimen slide is moved top to bottom, the image seen moves from bottom to top. This can be very confusing.
