How are absorption and emission lines produced in a stellar spectrum What information might absorption lines in the spectrum of a star reveal about a cloud of cool gas lying between us and the star?
Absorption lines are produced when elements in the outer layers of a star absorb specific wavelengths of light, leading to dark lines in the spectrum. These lines indicate the presence of certain chemical elements in the star's atmosphere. Absorption lines from a cool gas cloud between a star and Earth can reveal the composition, density, and temperature of the cloud, providing valuable information about the interstellar medium.
The light from stars are used to determine what?
The light from stars can tell us what type of star it is (our Sun is a G type), the stars spectrum can tell us what elements are in the star, and its intristic brightness can help us determine how far away it is. Also, if there is a wobble in the star, or a change it the stars brightness can tell us if it has a planet.
How an absorption spectrum can identify a star's composition?
By looking at the lines in a star's spectrum of light, astronomers can tell what kinds of elements the star is made of. This happens because when a beam of light hits an atom or molecule, that atom absorbs a characteristic wavelength (color) of visible light. Scientists have made a huge list of different elements and the different patterns of lines observed in theirj corresponding "spectra" (fancy word for light spectrums), and by using such lists can deduce precisely what each star is made of.
How stars are there on the US flag?
There are 50 stars on the US flag, each representing one of the 50 states in the United States.
What information do space probes gather?
They basically study everything in space that a man can't reach. For instance, they tell us about weather patterns such as hurricanes and drought conditions on earth. They tell us things about the other planets in our solar system such as their weather, temperature, atmospheric composition, etc. They study the stars to see how stars and planets and galaxies are formed. They study deep space to show us how we might have come to be.
How do emission and absorption spectrums tell us about the composition of objects in our universe?
Each chemical element has a specific emission or absorption spectrum.

Can you tell us what is the name of those lines which are drawn in some part of earth?

What does the absorption spectrum show us or tell us?
The absorption spectrum shows the specific wavelengths of light that are absorbed by a material, indicating the energy levels of electrons in the substance. By analyzing the absorption spectrum, scientists can identify the chemical composition of the material and understand its electronic structure.
When the absorption lines of a galaxy shifts toward the blue end of the spectrum it means that that the galaxy?
It means the heading towards us, red means it is moving away from us.
What do lines of longitude tell us?
Lines of longitude tells us the degrees of the world. They are split up into the eastern and western hemispheres by the prime meridian.
What can a star's spectrum tell us?
scientists can tell the stars composition and temperature from its spectrum. Hope tht helps :]
Why might scientists mainly astronomers study the color of metals in a flame?
The colours with which an element (metal or other) burns in a flame are the same colours which are absorbed by that element in the sun's spectrum. The colours are very specific to each element and show up as distinct black lines in the solar spectrum. By studying the spectrum it is possible to tell what elements are in the sun [or star] and also their relative abundance.If a star is moving away from us absorption lines are red-shifted [move towards the red end of the spectrum]. The faster the star is moving away, the greater the red-shift. Also, as Hubble discovered, the greater the red-shift, the further away the star is. So the red shift in the absorption spectrum is a measure of not only how fast the star is receding from us but also how far it is. This allows us to tell whether two stars which are apparently in the same direction are actually close together or simply a coincidental alignment of their lines of sight.
How can humans tell if the earth is rotating?
Apart from believing what scientists tell us, watching the stars is positive proof. This is especially apparent when viewing a time delayed sequence of pictures taken with the Pole Star in the centre (in the northern hemisphere). Though there is slight movement of the Pole Star, all other stars move round the Pole Star and show as curved lines of light.
What are the lyrics to Stars by The Crookes?
These cheap clothes suit us darling. We're poor but happy darling. These cheap clothes suit us darling. We're in the gutter. Who cares? We're happy sweetheart. Here in the gutter. Tennessee's uptight. Baby said, 'I need you and you only, together we'll be lonely.' Tell me how the stars still smile on us and make the world disappear. Tell me in the darkness stars still smile on us. Tell me that you're dancing 'just because' and whisper softly in my ear. Tell me in the darkness stars still smile on us... These cheap clothes suit us darling. We're in the gutter. Who cares? We're happy sweetheart. Here in the gutter. Cassady's gone wild. What a gas! Pay fame on the never never, you always were so clever. Tell me how the stars still smile on us and make the world disappear. Tell me in the darkness stars still smile on us. Tell me that you're dancing 'just because' and whisper softly in my ear. Tell me in the darkness stars still smile on us... Oh if you dig I'll take you back to those lights. Lonely nights. Pay fame on the never never, you always were so clever. Tennessee was right when she said "I need you and you only, together let's be lonely."
How does the US flag look like?
The American flag has red horizontal lines and in one box there is full of stars in the blue background
