Scientists have discovered something unexpected about the Triangulum galaxy: In this satellite galaxy, a close companion of the much larger Andromeda galaxy, old and new stars occur in separate parts of the its structure, something not seen in galaxies like our own and so far not reporter for other satellite galaxies.

Astrophysicists Hunt for Second-Closest Supermassive Black Hole
As massive as the black hole at the center of the Milky Way, the behemoth is hosted by a dwarf galaxy less than 1 million light-years away. Invisible so far — maybe not for long.
No Trace of Dark Matter Halos
Dwarf galaxies are small, faint galaxies that can usually be found in galaxy clusters or near larger galaxies.
36 Dwarf Galaxies Had Simultaneous “Baby Boom” of New Stars
Three dozen dwarf galaxies far from each other had a simultaneous “baby boom” of new stars, an unexpected discovery that challenges current theories on how galaxies grow and may enhance our understanding of the universe. Galaxies more than 1 million light-years apart should have completely independent lives in terms of when they give birth to new stars. But galaxies separated by up to 13 million light-years slowed down and then simultaneously accelerated their birth rate of stars, according to a Rutgers-led study published in the Astrophysical Journal.
