Astronomers from the Netherlands, the United Kingdom and the United States have found no trace of dark matter in AGC 114905, a gas-rich ultra-diffuse galaxy approximately 248 million light-years from Earth.
AGC 114905 is located about 76 megaparsecs (248 million light-years) away in the constellation of Pisces.
It is classified as an ultra-diffuse dwarf galaxy, with the name ‘dwarf galaxy’ referring to its luminosity and not to its size.
AGC 114905 is about the size of our own Milky Way Galaxy but contains a thousand times fewer stars.
