Which types of galaxies contain the oldest stars?
Which type of galaxy contains the oldest stars?
elliptical galaxies Because elliptical galaxies contain older stars and less gas than spiral galaxies, it seems that the galaxy types represent part of a natural evolution: As spiral galaxies age, interact, and merge, they lose their familiar shapes and become elliptical galaxies.
What type of galaxy is the oldest galaxy?
GN-z11 The oldest known galaxy in existence remains GN-z11, which formed around 400 million years after the Big Bang, as previously reported by Live Science's sister site Space.com. Researchers discovered the ancient galaxy after finding a photo of it in the ALMA archive.
Which galaxies have the youngest stars?
Spiral galaxies are twisted collections of stars and gas that often have beautiful shapes and are made up of hot young stars.
Where are the oldest stars in our galaxy quizlet?
The halo of the Milky Way contains the oldest-known objects in the galaxy:globular clusters. Stars in the globular clusters have very small amounts of elements that are heavier than hydrogen and helium. Most young stars are located in the spirals of the disks, where interstellar gas and dust is.
What are the three oldest galaxies?

Do dwarf galaxies contain old stars?
Ultra-faint dwarf galaxies (UFDs) are a class of galaxies that contain from a few hundred to one hundred thousand stars, making them the faintest galaxies in the Universe.
Do dwarf galaxies have old stars?
If they happen to find many other instances of very old stars orbiting near the edges of dwarf galaxies, it will indicate that Dark Matter played a particularly important role in the merger of ancient galaxies and their subsequent evolution.
Where are the oldest stars in our galaxy located?
The Milky Way's bulge — a bulbous, 10,000 light-year-wide region of stars and dust popping out of the galaxy's spiral disc — is thought to contain some of the oldest stars in the galaxy.
