Which of the star clusters are youngest?

Which of the star clusters are youngest?

Answer and Explanation: A star cluster whose brightest main sequence stars are white is the youngest. The color of the star shows its age.

Which cluster is the youngest and which is the oldest?

Getting ages for many star clusters has led to some interesting results.

• There are star cluster ranging in age from 0 to 13 billion years.
• The Young clusters are in the disk of the Galaxy and the youngest are associated with gas and dust clouds.
• The Oldest clusters are in the Galactic Halo and Bulge.

Which cluster has the oldest stars?

Globular clusters contain several thousand to one million stars in spherical, gravitationally-bound system. Located mostly in the halo surrounding the galactic plane they comprise the oldest stars in the galaxy.

How can you tell which star cluster is older?

By placing the stars in a globular cluster on a Hertzprung-Russell diagram, astronomers can determine the cluster’s age by looking at the main sequence turnoff point and comparing it with models of stellar evolution.

What are the 7 stages of a star in order?

Seven Main Stages of a Star

• Giant Gas Cloud. A star originates from a large cloud of gas. …
• Protostar. When the gas particles in the molecular cloud run into each other, heat energy is produced. …
• T-Tauri Phase. …
• Main Sequence. …
• Red Giant. …
• The Fusion of Heavier Elements. …
• Supernovae and Planetary Nebulae.

What are the 12 stages of a star?

The formation and life cycle of stars

• A nebula. A star forms from massive clouds of dust and gas in space, also known as a nebula. …
• Protostar. As the mass falls together it gets hot. …
• Main sequence star. …
• Red giant star. …
• White dwarf. …
• Supernova. …
• Neutron star or black hole.

What is the youngest star system?

The young M-type star, AU Microscopium (AU Mic), is about half the mass of the sun but only about 12 million years old, compared to the 4.6 billion year age of the sun.

What is the first cluster?

The first commercial clustering product was ARCnet, developed by Datapoint in 1977. ARCnet was not a commercial success and clustering per se did not really take off until Digital Equipment Corporation released their VAXcluster product in 1984 for the VAX/VMS operating system.

What is the oldest galactic cluster?

the protocluster. A 13-billion-year-old intense galaxy-forming region has been spotted, giving researchers clues as to how huge networks of galaxies develop. In the present universe, fully formed galaxy clusters contain thousands of member galaxies including tens of massive galaxies.

What is the oldest star called?

Methuselah: The oldest star in the universe | Space.

What is the oldest star age?

List of oldest stars

Name	Age (billions of years)	Distance

2MASS J18082002-5104378	13.53	1 950 ly
BD+17°3248	13.8 ± 4	968 ly
HE 1219-0312	13.6	32 000 ly

What are the oldest types of stars?

About 200 million years after the Big Bang, the very first stars (called Population III stars) began to form. While Population III stars have yet to be detected by scientists, the oldest known stars that have been observed were born after the first stars went supernova.

How do you tell if a star is younger or older?

“It is impossible to determine the age of a single star all by itself. The only real means we have to determine stellar ages is through the study of star clusters.

How old are the stars?

They conclude that some began their lives as part of the Gaia-Enceladus-Sausage galaxy. The Milky Way is 13.5 billion years old and is thought to have merged with the Gaia-Enceladus-Sausage galaxy about nine billion years ago—it’s biggest collision event.

When did the first star cluster form?

Most are estimated to be at least 10 billion years old, and contain some of the oldest stars in the galaxy. The clusters likely formed very early, before the galaxy flattened into a spiral disc.

What is the correct sequence of a star?

Most stars lie on a line known as the “main sequence,” which runs from the top left (where hot stars are brighter) to the bottom right (where cool stars tend to be dimmer).

What are the 7 main types of stars?

The 7 Main Spectral Types of Stars:

• O (Blue) (10 Lacerta)
• B (Blue) (Rigel)
• A (Blue) (Sirius)
• F (Blue/White) (Procyon)
• G (White/Yellow) (Sun)
• K (Orange/Red) (Arcturus)
• M (Red) (Betelgeuse)

What is the order of the stars life?

All stars will expand, cool and change colour to become a red giant. What happens next depends on how massive the star is. A smaller star, like the Sun, will gradually cool down and stop glowing. During these changes it will go through the planetary nebula phase, and white dwarf phase.

What is the youngest star system?

The young M-type star, AU Microscopium (AU Mic), is about half the mass of the sun but only about 12 million years old, compared to the 4.6 billion year age of the sun.

What is the youngest stage of a star?

A protostar is a very young star that is still in the process of gathering mass from its parent molecular cloud. The protostar phase is the earliest one in the process of stellar evolution.

What is the youngest star ever?

Stars are being formed constantly in the universe so it is impossible to tell which star is the youngest….Age and distance.

Title	Nearest sun-like star
Object	Alpha Centauri A & B
Date	1839
Data	1.34 parsecs (4.4 ly)

What type of galaxy has 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.
