A blob of gas seen outside the Milky Way could be a type of starless, dark matter–dominated galaxy. Some scientists are skeptical.

A faint cosmic spin – one rotation per 500 billion years – could resolve the stubborn Hubble tension by tweaking standard ...

A groundbreaking discovery has rocked the field of neutrino astronomy—scientists have detected an ultra-high-energy neutrino ...

About half of the non-dark matter in the universe cannot be accounted for by stars and galaxies alone. Now, scientists say ...

Zhúlóng is the most distant spiral galaxy ever seen. It formed 1 billion years after Big Bang, yet has a calm structure like ...

While solitary black holes should be common, they are hard to find. The one in Sagittarius revealed itself when it passed in front of a dim background star, magnifying the star’s light and slowly ...

The rotating model, which does not break any known law of physics, suggests the universe could spin around once every 500 billion years. This would be far too slowly to detect easily, but enough to ...

In just the first 259 days of data collection, KATRIN, a beta-decay-based detector in Germany, has set the smallest upper ...

Scientists from CERN have discovered a signal that may indicate the existence of a new type of matter. The hypothetical ...

Quantum superposition is a phenomenon in which a tiny particle can be in two states at the same time — but only if it is not ...

Quarks are the reason protons have a positive charge. Each quark has a fraction of an electric charge. A proton has two up ...
