What type of galaxies are typically home to older stars?

Elliptical galaxies contain mostly older stars. That means they often aren’t as bright as spiral galaxies. They also have very little dust and gas. Elliptical galaxies are the largest and most common galaxies observed.

Where do the oldest stars in our galaxy live?

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.

What type of galaxy contains old stars only?

elliptical galaxies
History and formation. Because elliptical galaxies contain older stars and less gas, scientists think that they are nearing the end of the evolutionary line for galaxies.

Where are the older stars located in a spiral galaxy?

central 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.

What are the 3 galaxies?

Astronomers classify galaxies into three major categories: elliptical, spiral and irregular. These galaxies span a wide range of sizes, from dwarf galaxies containing as few as 100 million stars to giant galaxies with more than a trillion stars.

Is Milky Way oldest galaxy?

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.

What is the oldest galaxy ever found?

How old are the oldest stars in the Milky Way?

HE 1523-0901 is the oldest known star in our galaxy, the Milky Way. The star’s estimated age is about 13.2 billion years.

What galaxy is earth on?

the Milky Way
Earth is in the second largest galaxy of the Local Group – a galaxy called the Milky Way. The Milky Way is a large spiral galaxy. Earth is located in one of the spiral arms of the Milky Way (called the Orion Arm) which lies about two-thirds of the way out from the center of the Galaxy.

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.

What celebrities live in a $60 million house?

How old is the oldest known galaxy?

In recent years, astronomers have discovered some of the oldest known galaxies, which formed not too long after the Big Bang, which took place about 13.8 billion years ago. As technology has improved, scientists have been able to detect galaxies that stretch further back to the early formation of the universe.

How old are the Stars in the universe?

The team calculated that the stars likely date to the first billion years of the universe’s life — making them roughly 12.8 billion years old.
