Dark matter is so pervasive throughout galaxies that its presence explains the stability and motion of stars in systems such as the Milky Way. For example, current models indicate that our galaxy is ...

Dark matter keeps getting blamed for the universe’s big patterns while staying stubbornly out of reach. You cannot see it, touch it, or capture it.

Using the Hubble Space Telescope, astronomers have discovered what seems to be a galaxy that is the most heavily dominated by ...

Earlier this week, science writer Paul Sutter covered a bold new study that leans toward so‑called “fuzzy” dark matter as the ...

You know that feeling when you find something hiding right where you've been looking all along? Astronomers just had that moment on a cosmic scale. A galaxy so faint, so nearly invisible that no one ...

Now physicists from the University of Washington are taking a big swing at answering that question. All matter exerts gravitational force. The more mass the object has, the greater the force. Yet, a ...

The spacecraft bus that will deliver NASA's Nancy Grace Roman Space Telescope to its orbit and enable it to function once there is now complete after years of construction, installation, and testing.

NASA's Hubble Space Telescope captures the magnificent starry population of the Coma Cluster of galaxies, one of the densest known galaxy collections in the universe — and where the effect of dark ...

A new study suggests that dark matter may consist of particles with different masses. By introducing a two-component self-interacting dark matter model, the researchers show that both the low-density ...

Astronomers overwhelmingly agree a supermassive black hole anchors the Milky Way. But a new theoretical analysis explores a far more speculative possibility: not a black hole, but a dense knot of dark ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

The reddest galaxies with the largest central bulb show the largest bars -gigantic central columns of stars and dark matter-, according to a scientific study that used Google Maps to observe the sky.
