When astronomers using NASA’s Hubble Space Telescope
uncovered an oddball galaxy that looks like it doesn’t have
much dark matter, some thought the finding was hard to
believe and looked for a simpler explanation.
Dark matter, after all, is the invisible glue that makes up
the bulk of the universe’s contents. All galaxies are
dominated by it; in fact, galaxies are thought to form
inside immense halos of dark matter.
So, finding a galaxy lacking the invisible stuff is an
extraordinary claim that challenges conventional wisdom. It
would have the potential to upset theories of galaxy
formation and evolution.
