Mysterious Invisible Galaxy May Be Composed of Dark Matter
from the Christian Science Monitor
Astronomers have discovered a small galaxy that is invisible to telescopes and may be
completely composed of dark matter, which reflects no light.
The newfound galaxy is incredibly distant and extremely small. It orbits as a satellite of a
larger galaxy. Though telescopes can't spot the dwarf galaxy, scientists detected its presence
through the tiny distortions its gravity causes to light that passes it by.
Scientists think dark matter, which may be made of some exotic particle that doesn't reflect
light, makes up about 98 percent of all matter in the universe. Yet it has never been detected
directly. Discovering dark objects like this tiny, distant galaxy could help researchers
understand better what dark matter is and how it affects regular matter around it.
