What contains trillions of stars?
the night sky and/or large galaxies (elliptical or spiral)
What are facts about spiral galaxies?
milky way is a spiral galaxy spiral galaxies have younger stars in the arm and older stars in the middle
Do some spiral galaxies contain 1 trillion stars?
Yes. Some spiral galaxies do contain at least 1 trillion stars.
How old are the stars in spiral galaxies?
A spiral galaxy is just a type of galaxy but I can tell you that the stars in the middle are the oldest and the ones on the outside are the youngest.
Are spiral galaxies stars small?
some are big.
What are similarities between elliptical and spiral galaxies?
While spiral galaxies are bright, elliptical galaxies are dim. Spiral galaxies are hotbeds of star formation, but elliptical galaxies aren't nearly as prolific because they contain less gas and dust, which means fewer new (and brighter) stars are born
In which type of galaxy would you be most likely to observe a massive star supernovae in a giant elliptical galaxy or in a large spiral galaxy?
Large Spiral Galaxy. This is because they contain more of the OB stars that are required for a supernova event. Elliptical galaxies tend to be older and have more low mass stars and are not as common as spiral galaxies. See Link for more information
How are the spiral and elliptical galaxies the same?
Both contain large numbers of stars, plus dust, gas, and magnetic fields.
Can galaxies be formed by groups of stars?
Galaxies ARE groups of stars. Lots of stars though. Not just like 2 or 3...
How are galaxies and constellations similar?
They are both spiral galaxies. However, The Milky Way is a barred spiral galaxy (SBbc), whereas the Whirlpool Galaxy is a spiral galaxy without the bar (SAbc). See related links for a pictorial representation of the two types.
What do the arms of spiral galaxies contain?
(Atoms) Stars, Dust.
What are the waves that are produced by stars and galaxies?
Density waves (they cause the spiral arms in disc galaxies).
