Researchers at the University of Nottingham have developed a new method using a 3D-printed vacuum system to detect dark matter and potentially reveal the nature of dark energy. The system manipulates the gas density and uses ultracold lithium atoms to probe the effects of scalar fields, with the aim of observing domain walls: defects formed … Read more
Astronomers have discovered two new satellite galaxies of the Milky Way. The findings could help us better understand dark matter: the mysterious stuff that makes up about 85% of the matter in the universe, but remains essentially invisible to us. The discoveries also bring scientists one step closer to solving a persistent problem with the … Read more
Stars near the center of our galaxy could be forever fueled by dark matter, according to a team of astronomers who recently studied the distant light sources. Florida family sues NASA over home damaged by space debris The group of stars, known as S-cluster stars, are located just three light-years from the center of the … Read more
A galaxy orbiting next to our own about 380,000 light-years from Earth could provide new clues in the 90-year search for the nature of dark matter, the invisible glue that holds galaxies together. The mysterious substance is responsible for more than 80% of the universe’s mass, but has yet to be directly detected. Scientists say … Read more
Artist’s impression of a microlensing event caused by a black hole observed from Earth towards the Large Magellanic Cloud. The light from a background star in the GMC is diffracted by a putative primordial black hole (lens) in the Milky Way’s halo and magnified when observed from Earth. Microlensing produces very characteristic variations in the … Read more
Sign up for CNN’s Wonder Theory science newsletter. Explore the universe with news about fascinating discoveries, scientific developments and more. For about fifty years, the scientific community has been grappling with a substantial problem: there isn’t enough visible matter in the universe.

Using gravitational lensing, scientists have discovered that dark matter can extend more than a million light-years from galactic centers, proposing significant adjustments to our theories of gravity or the concept of dark matter itself. Credit: SciTechDaily.com Groundbreaking new research shows that the rotation curves of galaxies remain flat far away, confirming the predictions of modified … Read more
Researchers delve into a synthetic universe to help us better understand the real universe. Using supercomputers at the Department of Energy’s Argonne National Laboratory in Illinois, scientists have created nearly 4 million simulated images of the cosmos from NASA’s Nancy Grace Roman Space Telescope and the Vera C. Rubin Observatory, jointly funded by NSF (the … Read more
A recent study from the ARC Center of Excellence for Dark Matter Particle Physics suggests that neutron stars could play a crucial role in understanding dark matter. The study found that when dark matter particles collide into neutron stars, they can quickly heat these stars, potentially making them observable with future astronomical technologies. This rapid … Read more
