Scientists could have discovered a galaxy 15,000 more dense than the Milky Way

By Kieron Allen

Scientists using the Hubble Space Telescope believe they may have identified the densest galaxy ever to be discovered in our corner of the Universe.

M60-UCD1 has been described as an ultra-compact dwarf galaxy, weighing 200 million times more than our Sun with a density of stars 15,000 times greater and 25 times closer together than in the Milky Way, making it the most luminous and most compact galaxy of its type.

"Traveling from one star to another would be a lot easier in M60-UCD1 than it is in our galaxy," said Jay Strader of Michigan State University, US. "But it would still take hundreds of years using present technology."

By combining data from NASA’s Chandra X-ray Observatory and some of the world’s most advanced ground-based telescope, the original Hubble image has been transformed into an intricate composite showing the bright galactic centre and surrounding neighborhood.
