What types of stars do elliptical galaxies usually have?
Yes. However, the current rate of star creation is less than when the galaxies were younger.Yes. However, the current rate of star creation is less than when the galaxies were younger.Yes.

Why some elliptical galaxies are lens shaped where as others are quite spherical?
Very lens-shaped elliptical galaxies have a high amount of reddish stars. Hence both their shape (the "spiral arms" have pulled inward over time) and the color of the stars implies they are very old galaxies. Spherical galaxies - I'm not up enough on that topic, so I will leave that part of the answer to another.
What is an orphan star?
Not all stars belong to galaxies. Galaxies collide, and this process strips stars from their parent galaxy and hurls them into intergalactic space. The Hubble Space Telescope has detected a few hundred very bright, orphan, stars between the galaxies in the Virgo Cluster. Although stars most certainly form inside some collection of matter such as a galaxy, their history after formation can include being ejected from a galaxy and becoming an orphan star.
Which galaxy are the planets on?
Planets orbit stars, stars orbit a galaxy. Planets are not "on" anything. A lot of stars out there have planets - we are just finding out how many now that we have better techniques to find them. So probably all galaxies have at least some stars with planets.
How much space does stars and planets take up in the universe?
Our Milky Way is about 100,000 light years across. Some galaxies are larger than that, some are smaller.
Which stars are actually a galaxy?
No stars are actually a galaxy. All stars are stars and all galaxies are galaxies. Stars are found in galaxies. Some galaxies look like tiny dots in our night sky, so might look like a star, but they are not stars; they are galaxies.
Do some spiral galaxies contain 1 trillion stars?
Yes. Some spiral galaxies do contain at least 1 trillion stars.
Do some dwarf galaxies contain 1 billion stars?
Yes. Some dwarf galaxies contain at least 1 billion stars.
What are all the galaxies?
The collection of all visible or detectable galaxies is known as the universe. Each galaxy is a vast collection of stars--billions of them. Some galaxies have trillions of stars.
Are spiral galaxies stars small?
some are big.
Are there bigger galaxies than the Andromeda?
Yes. Some giant elliptical galaxies contain tens of trillions of stars.
What are some galaxy facts?
most ellipical galaxies have old stars
Where are galaxies?
Galaxies were made by God from the beginning of time.Answer:The scientific opinion is that galaxies result from the gravitational attraction of matter into stars and the interactions of the stars to form clusters of swirling stars.. The matter originated in the "Big Bang" that was the beginning of the Universe some 15 billion years ago.
Explain how all galaxies are similar?
All galaxies are massive clusters of stars scattered across the universe. Many galaxies take the same form, for instance, spiral and elliptical galaxies. Some galaxies also have a black hole in their center.

Is every star a different galaxy?
No. Individual stars make up galaxies, sometimes in huge numbers. Some galaxies can appear, in telescopes, as single stars but this is due to their great distance
Is a planet a cluster of galaxies?
No, a galaxy is a cluster of stars, some of which might have planets.
