Dark matter darker than previously thought
Highlights
Using observations from NASA\'s Hubble Space Telescope and Chandra X-ray Observatory, astronomers have found that dark matter does not slow down when colliding with itself, meaning it interacts with itself less than previously thought.

Washington: Using observations from NASA's Hubble Space Telescope and Chandra X-ray Observatory, astronomers have found that dark matter does not slow down when colliding with itself, meaning it interacts with itself less than previously thought. This finding narrows down the options for what this mysterious substance might be.
Dark matter is an invisible matter that makes up most of the mass of the universe. The colliding objects under observation are galaxy clusters. Galaxy clusters are made of three main ingredients: galaxies, gas clouds, and dark matter. During collisions, the gas clouds surrounding galaxies crash into each other and slow down or stop.
