Ghost galaxy discovered 300 million light years away

While most galaxies blaze with billions of stars, a rare few are so faint they are barely detectable.

These low-surface-brightness galaxies are largely made up of dark matter, making them extremely difficult to spot.

One of the most unusual examples, CDG-2, located 300 million light-years from Earth, could be among the most dark matter dominated galaxies ever identified.

Because these galaxies emit so little light, they are challenging to detect directly.

The research team used sophisticated statistical methods to search for patterns instead of brightness.

They looked for tight groupings of globular clusters, which are dense, spherical collections of stars that usually orbit larger galaxies.
