How do scientists determine the chemical makeup of the stars?
Different chemicals emit and absorb light at various wavelengths. Astronomers can look at the wavelength of light coming from stars and determine which chemicals must be present.
Which stars are brightest at ultraviolet wavelengths?
OB
What were scientists called in Jesus's time?
There were no "scientists". The closest would be the magi who studied the stars and other phenomena. Scribes were learned men, but they were interested in writings, rather than what we now know as the sciences.
Are stars really yellow?
No, they can be different colours, depending on the kinds of stars they are.
What are the evidences for Helium and Hydrogen in sun?
Scientists can determine the contents of stars using spectrometer (spectrograph or spectroscope.) Basically different compounds give off different wavelengths of of light. By measuring the light you can identify the compound.
Can stars have different colors?
Stars do have different colours. If you look carefully, you will see that there are differences between the colours of stars. Some are very different in colour to others, but you will only notice if you look at them carefully.
Why are stars different coulors?
Different sized stars burn at different temperatures. Different temperatures produce different colours. Stars that are moving away from us will shift their colours towards the red. This is called "Red shift".
Who looks at the stars?
Astrologers and Scientists (especially studying physics) look at the stars
What are the main colours of stars?
the main colors of stars (from hottest to cooler) are blue, white, yellow, orange, red.
How star colors are made?
Stars derive their colours from the elements present.
What gives stars their colours?
Their temperature. Red is the coolest and blue is the hottest.
What characteristics do scientists measure to determine the temperature and composition of stars?
the light radiated from the stars
