Astronomers are able to identify chemicals in distant space with the use of spectral analysis. This breaks the light apart into a spectrum and find either emission lines or absorption lines and identifies which elements are present.

How can you tell type of silver in a spoon?
You look at the tiny markers stamped into each silver object. These have codes indicating purity and often also indicating where and when the object was made and sometimes, by which silversmith. If you don't find any markers, the object is not made of silver.
How can you tell if something is made out of copper?
Assay it
How do you tell if necklace is crystal?
I can't tell if you mean "crystal" as in "made of a crystalline material" or "crystal" as in "made of lead crystal, which is not technically a crystal at all". Take it to a jeweler. There's not any simple foolproof way a layman could tell.
What chemical is made when hydrogen burns?
i dont know? why do you tell me :)
How can you tell if something is made of gold?
First you must determine the volume of the gold object. This can be done by using a container with water that is on a scale. The weight of the container and water has to to be recorded or the scaled "zeroed out" with the water and container on it. Next you suspend the gold object with a fine thread in the water. For simplicity it is better to use grams for weight and cubic centimeters (1 cc= milliliter) for volume. The difference of weight caused by the suspended gold is equal to the weight of water with the same volume as the gold object. Since one cubic centimeter of water weighs one gram this ralationship allows for conversion from weight directly to volume. Now that you know the volume of the object you need to multiply it by the density of gold, 19.3 grams per cc. Now put the gold object on the scale and see how much it weighs. The calculated answer and the scale reading should be the same if it is made of gold.
Can astronomers tell what a distant object is made of?
spectrocity...absorption of select frequency of light ie spectrocity
How can astronomers tell what a distant object's temperature is?
blah blah black sheep
How can astronomers tell what a distant object's velocity?
By using the habo space telescle to detect the object's velocity
What can a stars spectrum tell astronomers about a star?
What elements the star is made of.
What does a red shift tell astronomers about the movement of an object?
"Redshift", which means that the frequency of the light as seen by us is LESS than the frequency at which it was emitted, tells us that an object is moving away from us.
How do you know what comets are made of?
Astronomers analyze the light reflected from comets with a machine, and can easily tell what major elements it is composed of.
What is it important for astronomers to study the sun?
SSo the astronomers can tell us what is happening to the sun. that good enough? :)
What can a stars spectrum can tell astronomers?
What makes up the star or element.
How do you tell if lover wants it over?
They get distant, but you have to see it.
How can astronomers tell how much objects in space weigh?
Weight is due to gravitational forces between two objects. A single object inspace without another one reasonably nearby, or even in gravitational free-falltoward another object, is weightless. So you can not weigh an object in space.Determining the mass of objects in space is another matter.
What is a use of examining light spectra?
One use of light spectra has an application in astronomy. When looking at distant objects like galaxies, you can tell if they are moving away from you or closer to you. If the spectral light appears blue (blue-shift) it means that the object is moving toward you, if the spectral light is red (red-shift) it means that the object is moving away from you. Another astronomy application is to look at the light from a star through a spectrum and by doing so you can figure out the chemical composition of the star just by the color of its spectrum.
Who can tell you about meteors?
The people you should ask are called astronomers who study astronomy.
