Forces have mediator particles. Electromagnetism is mediated by the photons, for example. So most of the decay of this excited dark matter particle would be this unknown mediator. The excited state ...

Last year, our most detailed map of the universe yet suggested our understanding of dark energy has been wrong for decades. The shock result is reigniting the search for a better cosmic story ...

Astronomers have just identified what appears to be a cosmic anomaly: a faint galaxy with so few visible stars that, according to calculations, as much as 99.9 percent of its mass is dark matter. The ...

David Joffe receives funding from NASA through a grant from the Georgia Space Grant Consortium. Curious Kids is a series for children of all ages. If you have a question you’d like an expert to answer ...

A huge clump of dark matter could be sitting on our galactic doorstep. Scientists found evidence of an invisible, massive nugget in the galactic neighborhood of the sun. The suspected clod of dark ...

A new high-resolution map of dark matter, created using data from NASA’s James Webb Space Telescope, is offering more clues into the part the mysterious stuff plays in the formation of universe. The ...

Scientists are shining a brighter light on dark matter thanks to a new high-resolution map, unveiling the invisible material that shapes everything we see. Using James Webb Space Telescope’s (JWST) ...

A new high-resolution map of distant galaxies may help scientists understand a mysterious invisible substance that helps hold the universe together. The ordinary matter all around us — stars, planets ...

NEW YORK (AP) — A new high-resolution map of distant galaxies may help scientists understand a mysterious invisible substance that helps hold the universe together. The ordinary matter all around us — ...

Dark matter is a mysterious substance that glues galaxies together. This map from the James Webb Space Telescope could help scientists finally figure out what it is. Using data from the James Webb ...

Astronomers found evidence that dark matter and neutrinos may interact, hinting at a "fundamental breakthrough" that challenges our understanding of how the universe evolved. When you purchase through ...

"WIMPs are still the leading candidate for dark matter, but billions of dollars of experiments have been done, only getting stronger and stronger upper limits, so alternative scenarios have to be ...
