How can absorption and emission spectra be used by the Hubble space telescope to study the structured of stars or other objects found in deep space?
The light generated by stars is mostly generated by hydrogen fusion. The light emitted from hydrogen has a distinctive emission spectrum. The emission spectrum undergoes shifting when the source and the receiver (Hubble) are moving in relation to each other. The spectrum will shift to the higher frequencies and shorter wavelengths ("blue shift") when the source and receiver are moving towards each other. Due to the "fact" that the universe is expanding, the source and receiver are moving away from each other. This causes the emission spectrum to shift to lower frequencies and longer wavelengths ("red shift"). The amount of red shift is an indication of the rate at which the cource and the receiver are moving away from each other. The expanding of the universe implies that the farther a source is from the receiver, the farther away the source and receiver are from each other. The red shifts of current objects have estimated that the farthest objects that we see are ~10-15 (not sure of exact number) billion light years distant from earth.
As for absorption, the light emitted from a star that passes through gases of interspace and of planets will be absorbed at different wavelengths depending on the elements contained within the gas. This allows the determination of planetary atmospheres and intergalactic clouds.

What is a device that is used to observe distant objects?
A telescope.
Is the hubble telescope invasion of privacy?
No invasion of privacy. The telescope aims at the stars in space and not at objects on Earth.
Tool used to make distant objects appear closer and clearer?
A telescope is used to make distant objects appear closer and clearer by gathering and focusing light from faraway objects, allowing for magnified images to be viewed through the eyepiece.
Which instrument is used to see far off objects in space?
telescope
An optical instrument that forms enlarged images of distant objects is called a?
telescope. It uses lenses or mirrors to collect and focus light from distant objects, allowing them to be seen in greater detail and clarity.
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.
What is the definition of a telescope?
The word telescope is from the Greek words meaning "distant" and "viewing" (looking). The telescope is : 1.) An arrangement of lenses or mirrors or both that focuses visible light, permitting better observation of distant objects. 2.) Any of various devices, such as a radio telescope, similarly used to detect and observe distant objects by their emission, transmission, reflection, or other interaction with invisible radiation.
What kind of heat transfer can happen between objects where there are no molecules?
Radiative heat transfer can occur between objects where there are no molecules. This type of heat transfer does not rely on the presence of a medium for energy transfer, as it involves the emission and absorption of electromagnetic radiation between objects at different temperatures.
An instrument that makes small distant objects visible?
telescope or maybe binoculars
What is a telescope that gathers x-rays from distant objects in order to produce the images of those objects?
X-ray telescope
What tool do scientist use to observe distant objects in the sky?
Terrestrial telescope
What do you use to study objects in the sky?
ITS A TELESCOPE.
How do you see objects in space?
Use a telescope.
A telescope that uses a set of lenses to gather and focus light from distant objects?
Refracting Telescope.
What characteristic of light to see objects?
absorption
Why do telescope in space get a more complete picture of space objects?
Because they are closer to the objects.
What are the specific uses of a telescope?
Studying of astronomic objects.
