Both - all galaxies contain young and old stars.
All galaxies
True
The center of the elliptical galaxy is very dense with many stars, and density decreases farther out.
Messier 32 is a dwarf elliptical galaxy about 2.65 million light years away in the constellation AndromedaMaffei 1 is a giant elliptical galaxy in the constellation about 10 billion light years away in the constellation Cassiopeia. It is the closest giant elliptical galaxy to the Milky Way
No. If a galaxy were not to rotate, it would soon collapse upon itself, due to its own gravitation.
No. The universe contains billions of galaxies including our own, and each galaxy contains billions of stars.
Generally stars will stay within a galaxy for their whole existence. However, stars toward the edge may succumb to gravitational attraction from other objects outside of the galaxy. Also, galaxies do "merge" with each other and during that process stars may well be "shot" off out of the galaxy. These processes are rare (in our lifetime), so you could say that the question is true.
Probably. The number of stars in the Andromeda galaxy is estimated to be around 1 trillion.
Yes it would. Our galaxy is a spiral and fairly flat. When we look around our own galaxy, some parts of the sky are only thinly populated with stars but there is a line of dense stars called the milky way which is looking through the flat disk of our galaxy. An eliptical galaxy is different. It is not a flat disk but more like a ball or an egg. If we lived near the centre, no matter which way we looked, the number of stars would be about the same. If we lived on the edge of the galaxy, one side of the night sky would be filled with stars and the other side would have very few to almost none.
True or False? Rewrite the statement The Sun is the largest star.
You can have dwarf elliptical galaxies.
Yes it is. All the stars that we can see are in the Milky Way galaxy. Stars in other galaxies are too far away from us to be able to see them properly. That is even true of many stars in the Milky Way Galaxy.
ore than a million. A galaxy with tens of millions of starts would be considered small. Out own galaxy has 200 billion to 400 billion stars. Some galaxies may contain more than 100 trillion stars.
If this was a true/false question, the answer is "False". The Milky Way alone contains over 200 billion stars and the Andromeda Galaxy has up to 1 trillion.
