What do measurements of light coming from deep space indicate about the stars>?
where in the reading? I dont have time to read this all:/
Why you don't have time for reading?
because I have volleyball practice soon
@thomaster
I really don't have any idea about this question :U_U But this question has made me curious! So I'll read it! :P But you need to read about it too!
Alright thank you I read the first two paragraphs...I hate bio and physics and chem
I love learning new things! So I'm reading about this!
You love Maths then? :P
Not really..I dont like school at all lol maybe if I had better teachers because Im stuck with the ones I dont like
Haha! Same here! But I love studying! And you should love it too xD
Lol I gues.... I wanna be rich and famous and not work my whole life
guess*
Did you find anything?

How can light teach us information about the stars? Electromagnetic radiation, or light, is a form of energy. Visible light is a narrow range of wavelengths of the electromagnetic spectrum. By measuring the wavelength or frequency of light coming from objects in the universe, we can learn something about their nature. Since we are not able to travel to a star or take samples from a galaxy, we must depend on electromagnetic radiation to carry information to us from distant objects in space. The human eye is sensitive to a very small range of wavelengths called visible light. However, most objects in the universe radiate at wavelengths that our eyes cannot see. Astronomers use telescopes with detection devices that are sensitive to wavelengths other than visible light; this allows astronomers to study objects that emit this radiation, otherwise invisible to us. Computer techniques then code the light into arbitrary colors that we CAN see. The Hubble Space Telescope is able to measure wavelengths from about 0.1150 to 2 micrometers, a range that covers more than just visible light. These measurements of electromagnetic radiation enable astronomers to determine certain physical characteristics of objects, such as their temperature, composition, and velocity.
Thank you!
You're welcomeeeeeeeeee!
