What else can I help you with?
What galaxies do you have to see with a telescope?
ALL of them, except the Milky Way and the Andromeda galaxies.
The spectral lines from distant galaxies do not match spectral lines on Earth due to?
The spectral lines from distant galaxies do not match those on Earth because of the Doppler effect, cosmic expansion, and differences in elements present in the galaxies. These factors cause the observed spectral lines to be shifted or altered compared to what we see on Earth.
What are galaxies and stars?
See related questions.
What can the Hubble telescope see?
You can see Earth, Mars, the Moon and galaxies!
How would the spectra from galaxies appear?
They have broad emission lines of highly ionized elements.
Are hydrogen atoms properties different in different galaxies?
No, Elements are the same everywhere in the Universe.
When scientists look at very distant galaxies through powerful telescopes they see the galaxies as they were millions or billions of year ago. Why is this?
The vast distances involved means that the light we see left those galaxies a long time ago.

What galaxies can you see?
The closest ones near our galaxy.
Do galaxies have names?
Yes. See related question.
What are spiral and elliptical galaxies?
See related questions.
What number of galaxies are in hubble field?
They are literally "uncountable"; every time we improve the telescope, we see more and more galaxies.
