Open star clusters contain a group of luminaries that are usually about the same age. However, observations show that NGC 1805 includes stars of two generations, separated by millions of years.

The captured luminaries are located very close to each other. They can be compared to bees swarming around the hive.

In the above image, the cluster NGC 1805 appears as a group of bright points of several colors – blue, white, and orange-red. Many of these stars are relatively recently formed.
