Here are some galaxies that are almost entirely dark matter: 

• FAST J0139+4328: This galaxy emits very little light and has only a few stars. 
• Sagittarius: This dwarf galaxy is loaded with dark matter. 

Dark matter is a hypothetical form of matter that doesn’t interact with light or the electromagnetic field. It’s implied by gravitational effects that can’t be explained by general relativity. 

Here are some other facts about dark matter: 

• In the standard Lambda-CDM model of cosmology, dark matter makes up 85% of the total mass of the universe. 
• In “normal” cases, only 2% of the mass of a dwarf galaxy is made up of non-dark matter. 
• Dark matter is difficult to detect in a laboratory.

Astronomers have found a galaxy that’s almost entirely dark matter. It’s called Dragonfly 44.  This galaxy is as big as the Milky Way and has less than 1% of the stars of the Milky Way. Only 0.01% of the galaxy is ordinary matter like stars and planets. 

Astronomers have also found a galaxy called FAST J0139+4328 that’s almost entirely dark matter. This galaxy emits very little light and has only a few stars. Its low luminosity suggests there are no stars, only clouds of gas. 

Astronomers have also found several galaxies that seem to lack dark matter altogether

Yes, dwarf galaxies contain dark matter.  Dwarf galaxies are small galaxies with a few billion stars.  They contain more dark matter than large spirals.  The mass of dark matter in dwarf galaxies can be thousands of times that of luminous matter. 

In cosmic simulations, dwarf galaxies have dark matter density that increases toward their cores. However, when observing dwarf galaxies, they don’t display this dark matter architecture. A study of the gravitational distortion of dwarf galaxies appears to support a theory of modified gravity rather than the existence of dark matter

Here are some other galaxies that are almost entirely dark matter: 

• Dragonfly 44 This galaxy is as massive as the Milky Way, but it’s only 1% as luminous. It’s made up of 99.99% dark matter. 
• Nube This galaxy has a very low surface brightness and is as massive as the Small Magellanic Cloud (SMC). 

Astronomers have long theorized the existence of dark galaxies, but there are no confirmed examples to date

Yes, most astronomers believe that dark matter exists.  There is evidence that dark matter exists in the universe.  For example, astronomers have observed how light is distorted by galaxy clusters, which is called gravitational lensing.  They have also calculated that galaxies would not have formed without a large amount of unseen matter. 

However, there is no direct detection of dark matter. We can’t shine a flashlight on it and see it because it doesn’t interact with normal radiation wavelengths. We can’t test whether dark matter exists on Earth. 

Dark matter is thought to be non-baryonic in nature. It’s made up of about 4.5% of the universe. The rest of the universe is made up of normal matter, which is less than 5%.
