Where are stars mostly found?
galaxies
Stars are born within the clouds of dust and scattered throughout most galaxies. A familiar example of such as a dust cloud is the Orion Nebula. Turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction.
Where do the oldest stars in our galaxy live?
They’re found in the halo, a roughly spherical component of the galaxy that formed first, in which old stars move in orbits that are highly elongated and tilted. Younger stars in the Milky Way rotate together along the galaxy’s disc in roughly circular orbits, much like horses on a merry-go-round.
Where is the best place to find many stars forming?
The most well-studied molecular cloud is Orion, where star formation is currently taking place. Molecular clouds typically contain regions of higher density called clumps, which in turn contain several even-denser cores of gas and dust, each of which may become a star.
Where are population 2 stars found?
halos
RR Lyrae variable stars and other Population II stars are found in the halos of spiral galaxies and in the globular clusters of the Milky Way system. Large numbers of these objects also occur in elliptical galaxies.
Where are older stars found in spiral galaxies?
bulge
Most spiral galaxies contain a central bulge surrounded by a flat, rotating disk of stars. The bulge in the center is made up of older, dimmer stars, and is thought to contain a supermassive black hole. Approximately two-thirds of spiral galaxies also contain a bar structure through their center, as does the Milky Way.
Where are population 1 and 2 stars found?
Populations I and II Stars They are particularly found in the spiral arms. With the model of heavy element formation in supernovae, this suggests that the gas from which they formed had been seeded with the heavy elements formed from previous giant stars. About 2% of the total belong to Population I.
Where are population 2 stars located in the Milky Way?
RR Lyrae variable stars and other Population II stars are found in the halos of spiral galaxies and in the globular clusters of the Milky Way system.
Which planet is the oldest?
The planet is one of the oldest known extrasolar planets, believed to be about 12.7 billion years old….PSR B1620−26 b.

Where are old stars found in a spiral galaxy?
Where’s the center of the Milky Way?
Sagittarius
The center of our Milky Way galaxy is located some 26,000 light years away, in the constellation of Sagittarius! That is very far, even on a galactic scale. Our galaxy is shaped like a large distorted pinwheel, with upwards of 200 billion stars!
How old are the oldest stars in the Milky Way?
Astronomers Find Fossils of Early Universe Stuffed in Milky Way’s Bulge. New research shows that star cluster HP1 (seen here through Chile’s Gemini South telescope) may contain some of the oldest stars in the Milky Way, dating to roughly 12.8 billion years old.
Where are population II stars found?
Population II stars tend to be found in globular clusters and the nucleus of a galaxy.
How old are the Stars in our Solar System?
The work marks the first time astronomers have pinned precise ages onto these ancient stars, which are a whopping 10 to 13 billion years old.
Where are the young stars in the Milky Way hanging out?
HONOLULU – A cluster of young stars in the Milky Way is hanging out where it seemingly shouldn’t exist. Our galaxy is enveloped in an extensive halo of old stars and hot gas — gas which can’t cool down enough to clump together and form new stars.
