A new image from the Hubble Space Telescope shows a small dwarf galaxy called IC 3430 that’s located 45 million light-years away. This galaxy is classified as both a dwarf galaxy, because of its small ...

The least massive galaxy in the known universe has been measured by UC Irvine scientists, clocking in at just 1,000 or so stars with a bit of dark matter holding them together. The findings, made with ...

Galaxies come in many different shapes and sizes, including those considerably smaller than our Milky Way. These smaller galaxies, called dwarf galaxies, can have as few as 1,000 stars, compared to ...
