A collection of tiny galaxies located roughly 3 million light-years away have been discovered.

Small dwarf galaxies should have been destroyed in the hotter and denser conditions of the early universe.

Yet somehow, this tiny galaxy survived without being fried.

Andromeda XXXV is about 20,000 solar masses and yet it was forming just fine for a few billion years .

The team's research was published on Tuesday ( March 11 ) in The Astrophysical Journal Letters .

Arias: "There are so many things that we still need to learn — even about what's near to us — in terms of galaxy formation, evolution, and structure".
