A team using the NASA/ESA Hubble Space Telescope has uncovered a new type of astronomical object—a starless, gas-rich, dark-matter cloud that is considered a "relic" or remnant of early galaxy formation. Nicknamed "Cloud-9," ...

In the early 1930s, Swiss astronomer Fritz Zwicky observed galaxies in space moving faster than their mass should allow, prompting him to infer the presence of some invisible scaffolding—dark matter—holding the galaxies together. ...

Dark matter, although not visible, is believed to make up most of the total mass of the universe. One theory suggests that ultralight dark matter behaves like a continuous wave, which could exert rhythmic forces that are ...

A team of astronomers and astrophysicists at the Chinese Academy of Science's National Astronomical Observatories has found evidence suggesting that a "gas clump" in a fast-moving cloud in the neighborhood of the Milky Way ...
Using the Green Bank Telescope (GBT), astronomers have detected a new giant molecular cloud in the Milky Way galaxy. The newfound cloud has a size of nearly 200 light years and its mass is estimated to be some 160,000 solar ...
For decades, people have been trying to directly detect dark matter: the missing mass in our universe. Now, there's a new, super-sensitive detector on the case—and even though it's still in the research and development phase, ...
