For decades, astronomers have believed that dark matter and dark energy make up most of the universe. However, a new study suggests they might not exist at all. Instead, what we perceive as dark ...

Galaxies are far more than the sum of their stars. Long before stars even formed, dark matter clumped up and drew regular matter together with its gravity, providing the invisible scaffolding upon ...

New research suggests the supermassive black hole at the heart of the Milky Way is actually a tremendously massive yet compact clump of dark matter. Scientists say this clump would exert the same ...

The Bullet Cluster of galaxies might only have half as much dark matter than scientists thought, or perhaps even none at all, ...

The Universal Rotation Curve does not stop where the stars end. It continues into the most remote regions of spiral galaxies, where dark matter dominates. This is the finding of a study conducted by ...

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 ...

The Nature Index 2026 Research Leaders reveal the leading institutions and countries/territories in the natural sciences, health sciences, applied sciences and social sciences, according to their ...

Be careful out there, astronomers: There could be a dark galaxy in our midst. In research published today in Science Advances, researchers from the Chinese National Academy of Sciences discovered that ...

Dark matter doesn’t emit, absorb, or reflect light. It’s invisible but supposedly makes up 85% of the universe’s mass. Because it’s so abundant, astronomers believe it should explain many unsolved ...

Ask most astronomers, and they’ll tell you that dark matter and dark energy make up more than 95 percent of the universe and that they are the explanations for many of the large-scale phenomena we ...
