Fusion power has long been sold as the technology that could light our cities with the same process that powers the stars.

Dark matter is an elusive type of matter that does not emit, absorb or reflect light, interacting very weakly with ordinary ...

A newly discovered celestial object may be a starless cloud that could change how astronomers understand dark matter.

Physicists have spent decades chasing two grand technological dreams: harnessing fusion power and uncovering the nature of ...

Scientists are uncovering dark matter, the biggest secret in the universe, with new detectors built to sense what was once ...

Scientists build ultra-sensitive detectors to study dark matter and dark energy, which make up most of the universe but remain unseen and poorly understood ...

New results from the world's most sensitive dark matter detector put the best-ever limits on particles called WIMPs, a leading candidate for what makes up our universe's invisible mass. Figuring out ...

Scientists still don’t know what dark matter is. It doesn’t interact with any electromagnetic force or regular matter except through the gravitational force it exerts. A research team has a come up ...

Researchers may have identified what could be a compelling clue in the ongoing hunt to prove the existence of dark matter. A mysterious diffuse glow of gamma rays near the center of the Milky Way has ...

Dark matter is one of nature's most confounding mysteries. It keeps particle physicists up at night and cosmologists glued to their supercomputer simulations. We know it's real because its mass ...

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 ...
