For decades astronomers have used computer models to predict how these dwarf galaxies should orbit large galaxies.

It had been a mystery how some dwarf galaxies can be so devoid of stars, while remaining full of dark matter.

As Wetzel explained: «By improving how we modeled the physics of stars, this new simulation offered a clear theoretical demonstration that we can, indeed, understand the dwarf galaxies we've observed around the Milky Way.

«This mass range gets interesting, because these «ultra-faint» dwarf galaxies are so faint that we do not yet have a complete observational census of how many exist around the Milky Way.

Stuart Clark describes how a superfluid Bose - Einstein state of dark matter particles might explain the streams of dwarf satellite galaxies in polar orbit around the Milky Way and Andromeda galaxies (2 April, p 30).

That may mean that there's another way to create this kind of isolated dwarf galaxy — and it could offer clues to how galaxies in the universe form.

The dwarf galaxy also is of interest because it provides clues to how the early simple universe became re-ionized by early star formation, moving it from the so - called cosmic Dark Ages of neutral gases to the development of the complexly structured universe now in existence, where the gas between galaxies is ionized.

This rare opportunity to observe a dwarf galaxy as its gas is removed by the effects of a nearby giant galaxy will allow scientists to learn more about how this process happens.

Their merger into large galaxies, therefore, could explain how fresh material is available for the formation of G - dwarf stars.

But contained within these dead stars, called white dwarfs, is the early history of our galaxy, providing clues on how it came to be.

If we could find other systems that look like the LMC — SMC — Milky - Way system, we might be able to learn more about pairs of dwarf galaxies and how they interact near the halos of large galaxies like the Milky Way.

By comparing Hubble's observations with those from the Spitzer Space Telescope the CLASH team was able to rule out red stars, brown dwarfs, and red galaxies as alternative explanations and concluded that the three images were a match for how the object would appear through the gravitational lens.
