<u>Answer:</u>
Same age stars is a mark of a galaxy formed by collapse.
<u>Explanation:
</u>
- Before a galaxy is formed, the building material of the galaxy in a protogalactic cloud that is rotating at a great speed rapidly accumulates and collapses in itself owing to its own gravitational pull.
- With this collapse, globular clusters are formed away from the nucleus of the galaxy.
- These clusters give birth to halo stars more or less at the same time. Thus, the stars that are formed of the same age.
- Sometimes, the reference of the age of the stars is taken to determine the age of the entire galaxy.
