The nearby dwarf galaxy NGC 1569 is a focus of vigorous stellar birth activity; the huge bubbles it exhales screen the main body of the galaxy, also producing bright blue star clusters. This galaxy suffered a sudden access of stellar birth 25 million years ago, which subsided when the first human ancestors populated the Earth. NGC 1569 is an irregular dwarf galaxy located 7 million light years towards the constellation Camelopardalis.
One of the mysteries of Astronomy still unresolved is how and when the formation of the galaxies took place and their subsequent evolution. Most of the galaxies we observe today seem to have already completed their formation at very early stages in the history of the Universe. Its development involves one or more galactic collisions and / or strongly enhanced stellar birth events, called "starbursts."
Any galaxy in formation is too far away for even Hubble to be able to study its star populations in detail. However, their local counterparts, starbursts and collision galaxies, offer particularly easy targets. NGC 1569 is especially suitable, as it is one of the closest starbursts galaxies. It houses two prominent recent massive clusters that could compete with the globular clusters of our galaxy, plus a large number of small star clusters comparable to the lax open clusters of our environment.
